(Oak Brook, Illinois, United States) — Joint Commission International (JCI) has appointed new leaders in its global accreditation and consulting services as the fast-growing organization reached a milestone of recognizing 600 JCI-accredited health care organizations in 57 countries.
Paul Chang, MD, MBA, MPH, CPHQ, FACHE, is now Vice President, Accreditation, Standards, and Measurement, having served as Senior Executive Director in 2013. Dr. Chang joined JCI in 2007 as the Managing Director of JCI's Asia-Pacific Office, where he collaborated with regional ministries of health, government and non-government agencies, hospitals, and other organizations to improve health outcomes, quality, and safety. He brings unique perspectives to his new role in JCI, having previously served in the Singapore Ministry of Health and having led Changi General Hospital, an 800-bed public hospital, to achieve JCI accreditation and JCI disease-specific certification in two cardiology programs.
Dr. Chang takes over for Paul vanOstenberg, DDS, MS, who served in the vice president role for many years. Dr. vanOstenberg has been appointed to a new JCI position as Senior Advisor, Global Growth and Innovation, where he will help identify client needs, enhance JCI's regional presence, and continue to work with JCI's innovative projects in resource-poor countries. He has a long and pioneering history with JCI, having served as the first Managing Director of JCI's Europe Office and later as the first Managing Director of JCI's Asia-Pacific Office. Dr. vanOstenberg was appointed as JCI's first Executive Director of International Accreditation in 1998, a position that evolved into the vice president's role. During 2013, he led the release of the much-anticipated fifth edition of the Joint Commission International Accreditation Standards for Hospitals, a triennial update on global standards for quality care and patient safety, and introduced an accreditation pathway for health care networks.
"My new position provides a focal point for the exploration of new ideas for our clients as well as countries not currently served by accreditation. These types of innovation bring JCI to new groups of potential clients and help extend our mission. As the leading international accreditation and quality improvement organization, JCI has the critical mass to explore the value and impact of standards, implement the International Library of Measures, and create a global benchmarking database," comments Dr. vanOstenberg as he looks forward to his new responsibilities.
Another high-profile addition to JCI's talented leadership team is Marwa J. Zohdy, PhD, Vice President, Global Consulting Services for JCI and JCR. Appointed in October 2013, Dr. Zohdy is leading accreditation and performance improvement consulting for health care organizations in the U.S. and more than 100 countries. In prior positions, Dr. Zohdy served in the Healthcare Systems and Services practice of McKinsey & Company, where she worked closely with health care leaders in the U.S., United Kingdom, Middle East, and North Africa. Her assignments included health system design and growth strategy, national health insurance reform, best practices in stroke and diabetes care pathways, and product/service innovation.
Dr. Zohdy explains, "Our clients work across every health care setting and are seeking true collaboration. We serve as experienced thought partners, collaborating with them to advance to the next level of standards compliance and quality performance. In addition to mock survey and accreditation preparation, JCI's rich consulting expertise can be customized to a client's needs, using global best practices adapted to each unique situation." She cites JCI's Safe Health DesignTM consulting as an example that appeals to growing markets in the Middle East and Asia-Pacific, where new hospital construction demands early-stage guidance to ensure that facilities conform to quality and safety standards.
During 2014, JCI will publish updated standards for ambulatory care, clinical laboratory, and medical transport services. For the first time, JCI-accredited organizations will have access to the hand hygiene Targeted Solutions Tool® (TST®) researched and disseminated by the Joint Commission Center for Transforming Healthcare, a not-for-profit affiliate of The Joint Commission that develops targeted solutions to solve health care's most critical safety and quality problems. JCI is also launching WorldHospitalSearch.org, a consumer-focused website that provides helpful health information to patients, including how to locate JCI-accredited organizations in specific countries.

"Big Jay" can't help it if his '62 Impala puts the competition in their place.
Marco A. Patiñoillustrator
We first saw this bad boy of a '62 Chevy Impala during one of our local LRM shows and quickly asked as to who owned the car. "Why, that's Big Jay's car and he's right here," exclaimed members of Uniques C.C. of the Inland Empire. Well, before you can say centerfold, names and numbers were exchanged and questions were asked and answered before shaking on the appointment. Big Jay works too many hours as an air conditioning technician and enjoys blowing off a little steam with his interests, which include coaching a T-ball team, hanging out with friends and, mostly importantly, raising two youngsters.
As far as cars, it's a lowrider's life that Big Jay lives. Lots of dough was "invested" in a project that took approximately 21/2 years from start to finish. Nothing's been left out; from top to bottom, "Bad Influence" has been meticulously worked over. A lot of the bright work found on the '62 was done by AB Metal Polishing in Ontario, California, and all of the glass and weatherstripping was swapped out during the build-up. Even the rims were treated to a little anodizing by the dudes in Uniques' Santa Ana chapter.
As for the dirty work, a warmed over 350-c.i.d. engine transfers its ponies through a modified driveshaft sporting a heavy duty carrier baring and a Positraction rearend can relay that bowtie power to the pavement. All in all, a very impressive effort for a normal guy who just wants to have fun with family and gives the onlookers a little shudder when his tight '62 Super Sport rumbles down the road.
Owner: Big Jay
Vehicle: '62 Chevrolet Impala SS
City/State: San Bernardino, California
Club: Uniques C.C. (Inland Empire)
Engine/Drivetrain: '76 Corvette 350-c.i.d. engine bored .060 over with a 91/2 to 1 compression, mild cam, Edelbrock intake and carb, Zoops billet pulleys, aluminum radiator all hard lined and built by Jim at Burns Machine Shop in San Bernardino. The tranny is an OG two-speed Powerglide that was rebuilt with a shift kit.
Body/Paint: Paul and John of A-1 Hydros in San Bernardino shaved the firewall and cleaned up the body before sending the car to George and Caesar at All Auto in San Bernardino for the killer House of Kolor candy Oriental blue paint over a silver base. Artist "Fonzi" of Montebello, California, got down on the sexy mural found on the '62, while Mike Lamberson did up the Impala logo on the roof and the striping and silver leaf accents along the panels.
Interior: B&B Classics in Upland, California, installed an OG style interior to match the blue exterior. Lil' J's Custom Upholstery in Riverside, California, did up the skins in the trunk area of the six-deuce.
Sound System: Glen at Modern Image in Moreno Valley, California, installed Eclipse and Precision power audio gear to make Bad Influence go "boom. "
Setup: John Valdez at A-1 Hydros in San Bernardino installed 8-inch cylinders in front and 12s in the back, 31/2-ton coil in front and 11/2-ton coils in the rear. Two Marzocchi pumps with #9 gears and three Adex square dumps are hard lined to A-1 Customs blocks. Ten Trojan batteries wired to 12-volt solenoids and a fully wrapped Canadian "X" frame round out the setup.
Tires: P155/80-R13 Triumph
Wheels: 13x7 100-spoke Dayton

It should not come as a surprise for you to think that quality water could be achieved through the cooperation established within the community at the end of the day. Yes, water treatment plants are a plausible outlet to such cleanliness, but in reality, having to maintain such refined quality needs to have the cooperation of the whole entire community in order to avoid having the water be contaminated at some point in its prominence. Not having any toxic material go to your water supply or even the bodies of water in general, would have you up for a good quality way of living that would for sure give you the utmost ease and comfort that you had wanted from the very start. This brings to you the realization of having to dispose those trash as properly as you can be, as having to do so would for sure give you the very best initiative of living your life whether personally or even professionally at that. It is very crucial in this case to have the whole populace be duly aware of water pollution and water quality, as having to emphasize such endeavors would for sure make them that much cautious of the things that they do in their personal or professional life in regards to environmental protection and awareness.
The outdoors are of course a great thing to explore in your own free time if you tend to be the free soul that you are. Despite having this as a liberating experience to go through, you may also tend to notice that there are indeed individuals out there that are not that keen on the disposal of items that they have under their own domain. While the impact of which may not seem apparent at first, it would eventually lead to a lot of issues that could be hard to come by sooner or later by the larger community involved in the pursuit of such quality supply to their way of living. Any tangible item out there could certainly be deemed as a contaminant, which could be detrimental to the overall environment in the process. Not only that, but those local water treatment plants would also be heavily affected by the pile up of wastes and contaminants coming their way in the process. Awareness at this very instance is an important thing to withhold in the community, as having people be cautious of their actions could lead to a whole new difference in the way how the water would be to their very own benefit.
Always keep it in your head that the water you are using is not yours alone to use whenever you like. Usable water is not that easy to replace, so do make it your very best to remain practical and conservative especially that nowadays, numerous advances have been made that may require the constant use of water as a means to do the usual methods of washing, taking a bath and of course, the most prominent of it all, drinking.

Energy efficiency is a global issue, both environmentally and economically. While oil prices rise demand for eletricity grows, and many are under the assumption that there's little we can do about it; we can only look at our energy bills and wince. But that, of course, isn't true. In fact, homeowners in the U.S. have the opportunity to make quite a difference in their energy spending, and it doesn't have to be difficult.
These numbers make it clear that a legitimate effort in bettering our energy usage must include homeowner participation. Unfortunately, so many people are deterred because 'energy efficiency' has been labelled expensive in our country. That association was likely born from the high costs of renewable energy sources like solar and wind, which have become trademarks of the green energy movement. But we don't have to make big investments to improve our carbon footprint, or save on those energy bills.
Air sealing, for example, is an extremely effective method for improving home efficiency, and it often yields a great ROI. But that's just one option, there are many other steps you can take: replacing old insulation and windows, or investing in a new furnace or ventilation system. The list goes on. Efficiency doesn't have to happen overnight, getting there is a process that's as gradual as you want it to be. If you're having trouble finding where to start, consider an energy assessment; it can give telling details about your home's energy consumption, and help prioritize the options available to you.


Lady Gaga is having a moment. While the six-time GRAMMY winner is musically in a league of her own, amassing a loyal following of "little monsters" and creating some of the most visually stunning music videos of all time, she's also proven her talents in other creative fields this year. Mother Monster showed her dark side as star of American Horror Story: Hotel, in which she played a vampire and for which she won a Golden Globe. Gaga also took the stage at the Oscars to perform a very special song she wrote as part of the soundtrack to the sexual assault documentary The Hunting Ground. But the singer also did what she does best at the GRAMMYs this year, where she performed a spectacular tribute to one of her greatest influences, David Bowie. As she celebrates her milestone 30th birthday on Mar. 28, we look back on the 10 things that make the "Just Dance" singer one of a kind.

Joseph Anthony Molloy (born March 13, 1961 in Tampa, Florida) is the former managing general partner of the New York Yankees from 1988 to 1998. He served as acting owner during the suspension of George Steinbrenner from 1992 to 1993.

Biography
Molloy attended St. Lawrence Catholic School and Tampa Catholic High School in Tampa, Florida. He attended a seminary for six months after high school. After deciding against clergyhood, Molloy obtained his college degree and became a science and physical education teacher at St. Lawrence. He also coached the school's basketball team.

Molloy married Jessica Steinbrenner, daughter of George Steinbrenner, the owner of the New York Yankees of Major League Baseball (MLB). Their first date occurred during the 1986 Hall of Fame Bowl and they married on November 7, 1987, at St. Patrick's Cathedral in New York. Molloy joined the Yankees in the summer of 1988. He was promoted to Vice President in 1989.

Steinbrenner was banned from the Yankees in 1990 for his association with a known gambler, whom he hired to find dirt on Dave Winfield. Hank Steinbrenner, George's oldest son, declined the opportunity to run the Yankees. Robert Nederlander, a limited partner in the Yankees, served as managing general partner for 16 months before resigning. Daniel McCarthy, also a limited partner, was rejected by the commissioner. The Yankees then appointed Molloy in February 1992. He was unanimously approved.

Under Molloy's leadership, the Yankees invested money into player development and scouting. He green-lit the selection of Derek Jeter in the 1992 MLB Draft. Steinbrenner was reinstated on March 1, 1993, and Molloy remained a general partner. Molloy planned the development of Legends Field as a new spring training complex for the Yankees. He was also involved in hiring Bob Watson as the team's new general manager.

In 1997, Molloy requested a one-year leave of absence from the Yankees due to the stress of the job and George's managing style. Molloy and Jessica separated in January 1998. He officially resigned from the Yankees in February, and filed for divorce in March. After leaving the Yankees, he returned to teaching.

In 2017, Molloy joined a group that attempted to purchase the Miami Marlins of MLB.

Joe and Jessica's son, Robert, is a film producer. He runs the production company Pinstripe Productions.

Physicist Jan Vogelsang uses innovative laser systems to study ultrafast processes. The University has awarded him a Carl von Ossietzky Young Researchers' Fellowship for his work.
Like a model or a film star on the red carpet, Jan Vogelsang is used to flurries of flashing lights. However, rather than being in the spotlight himself, he is the one to produce the flashes – more than a hundred thousand per second – using sophisticated laser systems. Incredibly fast processes are the focus of his experiments: Vogelsang is studying electron motion in nanostructures.
"My work is a bit like that of a sports photographer," explains Vogelsang (33), who has been conducting his research at the University's Institute of Physics on the Carl von Ossietzky Young Researchers' Fellowship since November 2020. "If he wants a shot of an athlete in mid-jump, he needs a fast shutter speed so that the image is sharp." In other words, the flash has to be shorter than the process that is to be caught on camera. And the processes Vogelsang studies occur in extremely short time intervals: it takes just a few attoseconds for an electron, excited by a laser pulse, to detach from an atom. For context, two attoseconds are to a second what a second is to the age of the universe (estimated at about 13.77 billion years).
From Oldenburg to Lund – and back again
So the light flashes Vogelsang uses have to be equally short. In his doctoral thesis, which he completed at the University of Oldenburg in 2019, he experimented with ultrashort light pulses and built an innovative electron microscope that can film processes in structures only a few nanometres (or billionths of a metre) in size. Using this microscope, he was able to obtain unprecedented spatio-temporal resolution and thus capture extremely small and ultrafast phenomena on film. For this research he received the Friedrich Hirzebruch Prize awarded by the Studienstiftung des Deutschen Volkes (German National Academic Foundation), as well as an Outstanding Doctoral Thesis Award from the University Society of Oldenburg (UGO). He then went to Sweden, where he spent three years as a post-doctoral researcher at Lund University and continued with his experiments, focusing on the new possibilities that the combination of electron microscopy and extremely powerful laser systems offers.
In Lund, Vogelsang used consecutive light pulses from this type of laser system to make sophisticated measurements. With a first light pulse he stimulated electrons to move within the nanostructures. Then he used a second light pulse to film the electrons in motion with the aid of an electron microscope. He repeated the process many times, varying the time intervals between the two pulses. In this way he was able to obtain images that showed the different stages of the process, and then compile the images into films.
The number of light pulses a laser system can produce within a certain interval of time also determines which physical processes can be investigated using this specific technique. "Conventional systems work with visible light and produce pulses that last a few femtoseconds," says Vogelsang. In lasers that use extremely shortwave ultraviolet light, the duration of the pulses can be further and significantly shortened, he explains. "However, generating large numbers of such short UV pulses is in itself very challenging and the subject of current research." The systems that Vogelsang worked with at Lund University and now plans to set up in Oldenburg could generate up to 200,000 pulses per second. He is thus expanding on research which is already taking place here, in the laboratories of Professor Christoph Lienau and Professor Matthias Wollenhaupt. "We will be able to complete in a single working day experiments that would previously have taken ten days to implement," Vogelsang says. This will pave the way for experiments that had so far been impossible because the laser systems function stably only for a limited period of time.
Testing techniques, optimizing solar cells
In order to test this new investigative method and its potential uses, Vogelsang is first applying it to processes that are already relatively well researched: he uses the light pulses to excite electrons in materials such as gold or silver and film their movements. However, it is structures that consist of several different materials, for example metals and semiconductors, that particularly interest him. Here, he aims to find out how the electrons move across the junctions between the different materials.
In the long term, his research could for example help to foster innovations in solar cells. "Silicon has already been optimized to a large degree, but for other materials there is still plenty of potential for further development," says Vogelsang. In current practice, scientists experiment with different materials on the basis of which they construct solar cells and then test their efficiency. However, what exactly happens when electrons are released from atoms in solar cells, thereby generating electric current, has not yet been fully clarified. Vogelsang's work could thus contribute to a more targeted selection and adaptation of new materials. "In this way, basic research can help to make practical experiments more efficient," says Vogelsang.

Intersystem crossing in thermally activated delayed fluorescence (TADF) materials is an important process that controls the rate at which singlet states convert to triplets; however, measuring this directly in TADF materials is difficult. TADF is a significant emerging technology that enables the harvesting of triplets as well as singlet excited states for emission in organic light emitting diodes. We have observed the picosecond time-resolved photoluminescence of a highly luminescent, neutral copper(I) complex in the solid state that shows TADF. The time constant of intersystem crossing is measured to be 27 picoseconds. Subsequent overall reverse intersystem crossing is slow, leading to population equilibration and TADF with an average lifetime of 11.5 microseconds. These first measurements of intersystem crossing in the solid state in this class of mononuclear copper(I) complexes give a better understanding of the excited-state processes and mechanisms that ensure efficient TADF.

Organic light-emitting diodes (OLEDs) (1, 2) have shown remarkable progress from a laboratory-based technology to large-scale industrial mass production. Key challenges remain in establishing low-cost high-efficiency materials for the conversion of as much of the injected charge into light as possible. The most promising strategy is the use of thermally activated delayed fluorescence (TADF) (3, 4), whereby otherwise lost dark triplet excitons are back-converted into emissive singlets, with intersystem crossing (ISC) being the fundamental process that governs the conversion of singlets to triplets and vice versa.
Initial OLEDs used singlet excitons formed in fluorescent materials, giving an upper limit of 25% for device efficiency due to spin statistics. In so-called "second-generation" OLEDs, namely, those that use metal complexes such as iridium(III) compounds, strong spin-orbit coupling from the heavy metal is used to enable fast ISC and triplet emission (5–9). Such phosphorescent emitters enable 100% of generated excitons to be harvested for the emission of light but require the use of heavy metals. The concept of TADF has proven to be an alternative strategy for high efficiencies based on more abundant starting materials with small spin-orbit coupling, such as luminescent copper(I) complexes (3, 10–21) or carefully designed organic emitters (4, 22–26). These materials also enable 100% internal device efficiencies by using both singlet and triplet excitons.
Recently, various copper(I) complexes with different structural motifs, such as tetrahedral or trigonal coordinated mono-, di-, tri-, or tetranuclear copper(I) complexes, have been studied (3, 10–21). In these materials, the central copper(I) atom with a moderate spin-orbit coupling (ξCu = 857 cm−1) (27) induces mixing of the excited singlet and triplet states and a small energy splitting between them, which leads to presumed fast intersystem crossing to the triplet and back. Repopulation of the excited singlet excitons at ambient temperature gives rise to thermally activated delayed fluorescence. This phenomenon was first proposed in the early 1980s by McMillin (28) for copper(I) bis(phenanthroline) complexes and later used by several research groups to design highly efficient emitting materials based on the plentiful metal copper. The use of singlet states (3, 14) enables copper(I) complexes to emit fluorescence at shorter wavelengths (compared to phosphorescence) because the excited singlet is naturally higher in energy than the triplet and has a short emission decay time, which are crucial for the efficiency of an OLED at high currents.
Particular organic materials designed to have a narrowed energy gap between the excited singlet and triplet states have also been found to show TADF (4, 22–26). In all efficient TADF emitters, the highest occupied (HOMO) and lowest unoccupied molecular orbitals (LUMO) are spatially separated on a donor and an acceptor part of the molecule, which leads to a small energy splitting between the excited singlet and triplet states (ΔEST) and thus faster ISC. The major difference of copper(I) complexes compared to all-organic molecules is higher spin-orbit coupling and thus intrinsically faster intersystem crossing. In addition to the generally faster emission decay times, the ease of emission color tunability by ligand variation makes copper(I) complexes an attractive alternative approach to organic emitters. A current challenge in the study of TADF systems is the unraveling of the various excited-state processes that occur, including radiative and nonradiative decay rates from the singlet, the rate of ISC, the rates of radiative and nonradiative losses in the triplet, and the rates of reverse intersystem crossing (RISC) from the triplet to singlet. Determining these rates can be challenging; thus, unambiguous observation of any of the key rates is valuable to the development of TADF materials. Knowing the rate of ISC enables the assessment of the suitability of materials as emitters in OLEDs, and as such is an important parameter in TADF systems.
This is the first known report on the intersystem crossing rate of a highly luminescent, TADF copper(I) complex in the solid state. This is crucial for the understanding of singlet utilization in OLEDs and the design of luminescent copper(I) complexes with short emission decay times. We chose a strongly emissive mononuclear TADF complex as a representative example of copper(I) complexes. We study the short-lived photoluminescence (PL) of the singlet metal-to-ligand and intraligand charge transfer (ML+IL CT) state by time-resolved emission and measure a time constant of 27 ps for ISC. The subsequent TADF is found to have an average lifetime of 11.5 μs.
We selected the compound [(bis(2-(diphenylphosphino)phenyl)ether)Cu(5-(2-pyridyl)tetrazolate)], denoted as [(DPEPhos)Cu(PyrTet)] (structure inset in Fig. 1), because this model compound represents an important class of neutral, mononuclear metal complexes that show TADF, assigned on the basis of a delayed component to the emission, the lifetime of which increases significantly when going to low temperatures along with a spectral shift indicative of change from singlet to triplet emission (11). It shows bright green emission with a peak at 535 nm and a PL quantum yield of 37% in neat film. The absorption and steady-state PL spectra of [(DPEPhos)Cu(PyrTet)] in amorphous powder and neat film are shown in Fig. 1.
Fig. 1 Absorption and emission spectra of [(DPEPhos)Cu(PyrTet)] in neat film.
The solid line represents neat film. The dashed line shows the emission spectrum of amorphous powder. a.u., arbitrary unit. The chemical structure of [(DPEPhos)Cu(PyrTet)] is shown in the inset.
As has been reported previously for this material in dichloromethane solution (11), the copper(I) complex exhibits strong absorption bands at 260 to 281 nm in film, which were assigned to ligand-centered transitions. Density functional theory (DFT) calculations predict a metal-to-ligand charge transfer (MLCT) transition with a strong intraligand charge transfer (ILCT) character localized on the anionic N^N ligand, which is confirmed by the very subtle 1MLCT shoulder at 339 to 341 nm. The PL maximum at 512 nm in the amorphous powder is red-shifted to 535 nm in the neat film, which is due to different intermolecular interactions or molecular environments, which could possibly lead to slightly distorted molecule geometries in neat film compared to powder (29–31). The strong influence of the environment on the photophysical properties of copper(I) complexes is further reflected in the broad emission spectra of [(DPEPhos)Cu(PyrTet)] as a result of a distribution of slightly different conformations.
Time-resolved photoluminescence was initially measured on a microsecond time range, and the results are shown in Fig. 2, with the experimental methods described in Materials and Methods. Luminescence decay dynamics at the PL maximum of the steady state TADF luminescence show long-lived emission, fitting to a biexponential decay function by convolving with the instrument response function (IRF) and giving lifetime components (and pre-exponential factors) of 7.5 μs (0.57) and 16.8 μs (0.43), which may correspond to different coordination environments in the film (31). A weighted average lifetime of 11.5 μs is determined by using the equation τAve = ΣAiτi/ΣAi, with Ai as the pre-exponential factors for the lifetime. In this measurement, any fast (<1 ns) dynamics are not observed owing to the long temporal response of the time-correlated single photon counting method.

The red solid line represents a fit to a biexponential decay with a time component of 7.5 μs (0.57 pre-exponential amplitude) and a component of 16.8 μs (0.43), which gives a weighted average lifetime of 11.5 μs. The IRF is also shown.
The picosecond luminescence decay dynamics of a neat film at a wavelength region 540 to 600 nm, which is around the PL maximum and on the red side of the PL, are shown in Fig. 3A, with the experimental details described in Materials and Methods. The observed decay can be fitted to a single exponential with a time constant of 27 ps when convolved with the IRF. This decay sits on a very strong background of long-lived emission lasting longer than 12 ns (the measurement frequency being 80 MHz), making the observation of the 27-ps decay challenging. Data acquisition over longer periods enabled the fast decay to become discernible from the background noise, with careful frequent sample position changes and monitoring of the background PL used to ensure that no sample degradation was occurring. To confirm that this decay does not embody a spectral shift within the singlet state, we recorded the time-resolved spectra as shown in Fig. 3B and found that in the time windows of 0 to 20 and 40 to 60 ps, the two PL spectra are essentially the same, and both agree with the PL spectrum for the long-lived (>12 ns) background from the measurement, which is representative of TADF emission. The long-lived spectrum was subtracted from both picosecond spectra to ensure that the background did not alter their shapes. Spectra without normalization that show the picosecond decay are provided in fig. S1A.

To understand the excited-state processes in the copper(I) complex [(DPEPhos)Cu(PyrTet)], we examined the photoluminescence on picosecond, nanosecond, and microsecond time scales to aid in our assignments. Figure 4 shows a schematic model of the photophysical processes in [(DPEPhos)Cu(PyrTet)].
Fig. 4 Schematic representation of excited-state transitions in [(DPEPhos)Cu(PyrTet)].
Shown are r, radiative transition (solid arrows); nr, nonradiative transition (oscillatory arrows). After excitation to the excited singlet state (Ia), intersystem crossing to the triplet state occurs (kISC). At sufficient temperature, the excitons are repopulated to the excited singlet state (kRISC), and subsequently thermally activated delayed fluorescence occurs. kS and kT depict the rate constants from the excited singlet or triplet state, respectively.
Our primary interest lies in what happens in the initial phase after excitation of the system, that is, how quickly excitons relax to the lowest excited singlet S1 state and then undergo ISC to the triplet state T1. From photoluminescence dynamics on the picosecond time scale (Fig. 3), a single fast decay of 27 ps is observed. We are left to interpret this decay with the knowledge that excitons in the triplet state do not emit much (or, more likely, any) light. Thus, when measuring the rapid decay of the PL in the wavelength region 540 to 600 nm, emission from the singlet state S1 is observed. The main processes that can occur after photoexcitation are relaxation to the lowest excited states/lowest energetic sites due to environmental inhomogeneity (32, 33) and ISC to the triplet state. Time-resolved spectra in the time windows of 0 to 20 and 40 to 60 ps are essentially the same, indicating that this decay is not linked to any spectral relaxation or vibrational cooling in the singlet state, showing that these processes must be faster or slower than the time scale that we focus on here. Dissipation of excess energy in processes such as S2 → S1 internal conversion was reported on a time scale of 50 to 100 fs for copper(I) bis(imine) complexes, whereas a subsequent flattening distortion is strongly correlated to the steric hindrance of the complex geometry and can reach subpicosecond time scales for complexes with bulky phenanthroline ligands (34–36) or can even be absent for sterically restricted molecules (37). However, substantial structural changes of the molecule [(DPEPhos)Cu(PyrTet)], such as the reported flattening distortion after excitation, apparently do not occur in the observed picosecond time window because this would result in a spectral red shift with time. To further confirm that exciton hopping to the lowest energy sites is not occurring on this time scale, we measured the complex in solution, and although the emission is weak, we find an almost identical decay time of 26 ps (Fig. 3A). The similar decay dynamics of [(DPEPhos)Cu(PyrTet)] observed for neat film and solution in the 100-ps time window indicate a similar coordination geometry around the copper(I) center in both film and solution due to an apparently restricted geometry, or only a marginal effect of the potentially distorted complex in solution on the ISC process (distortions in solid state are much more restricted). Because of the weak emission of the complex in solution, a detailed study of the photophysics would reveal differing processes at work. We speculate that molecular reorganization in the excited state leads to fast nonradiative decay. This is most likely from the triplet, owing to the very similar ISC time that is observed in solution and film. Indeed, the very similar times in solution and film tell us that the environment surrounding the complex [namely, tetrahydrofuran (THF) solvent molecules or other [(DPEPhos)Cu(PyrTet)] molecules] has little effect on the rate of ISC. Consequently, we assign the 27-ps process to ISC, consistent with the observation that, after this process, no further emission is observed on a time scale shorter than 12 ns (with the measurement frequency being 80 MHz); that is, all subsequent emission is delayed fluorescence. After the excitons have transferred to the triplet, reverse intersystem crossing back to the excited singlet occurs, giving TADF emission. The delayed component (Fig. 2) is reported as an average lifetime, consisting of two exponential decay components. The exact nature of these two components is out of the scope of this work but may well represent conformational disorder of the molecules in the film. What is important and interesting to note is that whereas conformational disorder may play a role in the dynamics of the delayed component, the process of interest here—ISC—is a single exponential decay of 27 ps, indicating that such disorder does not have an appreciable effect on the time constant of ISC. Reverse intersystem crossing is a subtle process that is difficult to observe. According to the Boltzmann statistics, very small proportions of the triplet state will return to the singlet at any given time, leading to a steady-state condition, with continual RISC to maintain the correct population ratios. Owing to the fast rate of intersystem crossing, RISC that does occur will have a high probability of being delivered straight back to the triplet again, thus leading to a high degree of cycling between the singlet and triplet with slow loss of population via singlet radiative decay in high-efficiency materials such as the complex studied here. We thus can conclude that the time constant of 27 ps found for the luminescence decay dynamics from 540 to 600 nm can be attributed to intersystem crossing from S1 → T1. This gives an ISC rate of 3.7 × 1010 s−1 (= τISC−1).
We investigated broadband picosecond transient absorption dynamics for [(DPEPhos)Cu(PyrTet)] in neat film to attempt to observe the ISC process (fig. S2). Because of spectral overlap of strong long-lived photoluminescence (535 nm), the negative signal of excited-state absorption (ESA) was very noisy despite subtraction of the background fluorescence before analysis. This forbade detailed tracking of the temporal dynamics; however, we can see that that ESA decays on a similar time scale of tens of picoseconds to that observed with much better quality data in time-resolved PL. This result qualitatively complements the assignment of the observed kinetics to ISC; however, if similar singlet and triplet ESA bands exist, or they overlap strongly with the photoluminescence, then the crossing can be very challenging to measure, as was found here.
The small spin-orbit coupling constant of copper (ξCu = 857 cm−1) is reflected in the rather slow ISC of 27 ps compared to iridium(III) complexes (ξIr = 3909 cm−1) (27) with ISC time constants of ~100 fs (6, 7). Nevertheless, copper(I) complexes can harvest both triplet and singlet excitons for the emission of light and achieve internal quantum efficiencies of 100% (10, 30) by using the smaller spin-orbit coupling for thermally activated delayed fluorescence.
When compared to reported ISC constants of copper bis(imine) complexes that exhibit TADF in solution (10 to 15 ps) (35, 38–41), the time constant of 27 ps in the studied TADF [(DPEPhos)Cu(PyrTet)] in the solid state appears to be slower than one would expect. This indicates a weak effective spin-orbit coupling in the molecular orbitals involved in the emission, which is intrinsically controlled by ligands and/or halides coordinated to the copper(I) center and the specific coordination geometry (38). DFT calculations also confirmed an ML+IL CT transition with a small percentage of copper(I) interactions (weak internal heavy atom effect) (19). In addition to the intrinsic control of the ISC rate by ligands and/or halides, the environment and morphology can have a strong influence by changing the molecular ground- or excited-state geometry or by opening up other channels for ISC by the ease of structural changes, for example, in solution (38, 41). This shows the importance of solid-state measurements for the understanding of photophysical processes in an OLED because this replicates the state of matter that exists in working devices. The benefit of faster intersystem crossing when compared to all-organic emitters is that a greater tolerance is enabled on the energy splitting between singlet and triplet; thus, modifications can be made to the chemical structure for advantageous optoelectronic properties with less risk of switching off TADF.
The overall PL lifetime that we observe for TADF is comparable to other mononuclear neutral copper(I) complexes based on N^N and P^P ligands, which exhibit TADF lifetimes in the solid state in a similar range, that is, 13 to 54 μs (3, 20, 42, 43). By applying different ligand systems (44) or by using polynuclear copper(I) complexes and introducing halides (13–15, 45), the TADF lifetimes can be significantly reduced down to 2 to 4 μs while still maintaining high PL quantum yields, thus leading one to ask what the rate of ISC would be in those materials.
To conclude, the picosecond dynamics of a highly luminescent TADF copper(I) complex [(DPEPhos)Cu(PyrTet)] have been measured in the solid state by means of time-resolved photoluminescence and transient absorption spectroscopy. In time-resolved photoluminescence measurements, we have observed a 27-ps decay representing intersystem crossing from the excited singlet state S1 to the triplet state T1 with a rate constant of 3.7 × 1010 s−1. This is the first time a direct observation of ISC in the solid state of a TADF copper complex has been reported, and contributes to the ability to understand the numerous excited-state processes by unambiguously measuring the rate of ISC. After the exciton has crossed to the triplet, reverse intersytem crossing back to the singlet occurs on a longer time scale by thermal activation, giving rise to an overall average PL lifetime of 11.5 μs. The copper(I) complex [(DPEPhos)Cu(PyrTet)] represents a promising class of emitter material for OLED applications. The determination of the ISC rate in such highly emissive compounds is challenging but very important for the understanding of the excited-state mechanisms in TADF materials that can be used in OLEDs. Implications of such fast intersystem crossing in a TADF OLED material include the realization of molecules that enable high device efficiencies without very demanding small singlet-triplet gap requirements; that is, fast ISC can be used to make up for a slightly larger gap while still enabling back-transfer from the triplet to singlet. For copper(I) complexes, future exploration of molecules with different structural motifs may offer the ability to (further) tune the ISC rate and, thus, the overall TADF efficiency and emission decay time to improve performance in OLEDs while also enabling adjustment of the emission color by ligand modifications.
The compound [(DPEPhos)Cu(PyrTet)] was synthesized according to literature methods (11). Solvents were purchased from VWR and Sigma-Aldrich at spectroscopic grade.
[(DPEPhos)Cu(PyrTet)] was studied as neat films prepared by dissolving the material in CH2Cl2 at concentrations of 20 mg/ml for streak camera and transient absorption measurements, and at 10 mg/ml for steady-state PL and time-correlated single photon counting measurements and spin-coating the solutions to form a solid-state thin film. [(DPEPhos)Cu(PyrTet)] was dissolved in THF for solution measurements; different solvents were used for solution measurements and film deposition owing to the required concentrations for spinning films. Because films were measured under an active vacuum of 10−5 mbar, any residual solvent would be removed from the film and would not influence the observed PL dynamics.
Photophysical measurements
All photophysical measurements were performed at room temperature, unless noted otherwise. Ultraviolet (UV)–vis absorption spectra were measured on a Thermo Scientific Evolution 201 UV-vis spectrometer and a Varian Cary 300 double beam spectrophotometer. Absolute PL quantum yields were measured using the integrating sphere method (46) with a Hamamatsu Photonics C9920-02G system purged by nitrogen. Emission and excitation spectra were recorded on a Horiba Scientific FluoroMax-4 spectrofluorometer. Emission lifetimes were measured under nitrogen on the same system using the time-correlated single photon counting method. For this, a SpectraLED was used as the excitation source [λ = 314 nm, pulse full width at half maximum (FWHM) = 493 ns]. Decay curves were analyzed with the software DAS-6 and DataStation provided by HORIBA Jobin Yvon. Streak camera measurements of neat films were taken at a range of wavelengths from 540 to 600 nm on a Hamamatsu synchroscan universal streak camera, measuring at 80 MHz, giving an instrument response of 2.5 ps (FWHM). Measurements were completed in vacuum at 10−5 mbar. The excitation source for streak camera measurements was at 375 nm, which was derived from the frequency-doubled output of the signal of a parametric amplifier with pulses at 20 kHz and 300 fs (FWHM), pumped by a Pharos regenerative amplifier from Light Conversion. Care was taken to keep peak excitation powers low to avoid exciton annihilation or degradation effects. Because prompt fluorescence in copper(I) complexes is very weak, the signals had to be averaged from several scans (no change was observed during integrations). Transient absorption studies were undertaken by the pump/probe technique with a Spectra Physics Hurricane regenerative amplifier, producing pulses of 100 fs at 5 kHz and 800 nm. The pump (400 nm) was obtained by frequency doubling the fundamental, whereas the probe was a white light continuum (420 to 760 nm) generated with 800-nm amplified light focused on calcium fluoride. Because dynamics >2 ps were of interest, the setup was not corrected for spectral chirp. Detection of the continuum probe was made with a silicon photodiode array from the company Entwicklungsbüro Stresing, with transient absorption measured by chopping the pump at 2.5 kHz. The measurements were carried out under an active vacuum of 10−5 mbar to minimize photodegradation.

AFCON 2021: Aubameyang back in training after negative Covid-19 test
Gabon have been handed a major boost ahead of their second Africa Cup of Nations group match against Ghana on Friday following the return of talisman and captain Pierre-Emerick Aubameyang.
The Arsenal forward missed the Les Panthères' opening match, a 1-0 win over Comoros, and will be hunting for a second win that will send them through to the knockout phase.
Aubameyang, who is out of favour at the London club, alongside Mario Lemina both tested positive last week, and their availability is a big relief for coach Patrice Neveu.
Neveu is however still unavailable as he continues with self-isolation following a positive test.
Gabon's last match of the group will be against Morocco on January 18, 2022.

Interesting facts about Basset Hounds
The Basset Hound is a breed of dog in the hound family.
Originally used to trail hares, rabbits, and deer, it has also been used in hunting birds, foxes, and other game.
Their sense of smell and ability to ground-scent is second only to the Bloodhound.
Short-legged and heavy-boned, the basset hound has long, pendulous ears and a short coat. It is usually bicolours or tricolours of standard hound colouration which is black, tan, and white.
The Basset Hound is from 28 to 38 centimeters (11 to 15 inches) tall and weighs from 20 to 34 kilograms (45 to 75 pounds).
The average lifespan for a Basset Hound is about 10 to 12 years.
The name "basset" is derived from the French word bas, meaning 'low', with the attenuating suffix –et — together meaning 'rather low'.
The earliest-known depictions of short-legged hunting dogs are engravings from the Middle Kingdom of Egypt. Mummified remains of short-legged dogs from that period have been uncovered in the Dog Catacombs of Saqqara, Egypt.
Scent Hounds were used for hunting in both Ancient Greece and Ancient Rome.
The basset type originated in France, and is descended from the 6th century hounds belonging to St Hubert of Belgium, which through breeding at the Benedictine Abbey of St. Hubert eventually became what is known as the St Hubert's Hound around 1000 AD.
It is believed that the Basset type originated as a mutation in the litters of Norman Staghounds, a descendant of the St Hubert's Hound.
Basset-type hounds became popular during the reign of Emperor Napoleon III.
The controlled breeding of the short haired basset began in France in the year 1870.
French basset hounds were being imported into England at least as early as the 1870s. While some of these dogs were certainly Basset Artésien Normands, by the 1880s linebreeding had thrown back to a different heavier type.
Everett Millais, who is considered to be the father of the modern Basset Hound, bred one such dog, Nicholas, to a Bloodhound bitch named Inoculation through artificial insemination in order to create a heavier basset in England in the 1890s. The litter was delivered by caesarean section, and the surviving pups were refined with French and English bassets.
The first breed standard for what is now known as the Basset Hound was made in Great Britain at the end of 19th century. This standard was updated in 2010.
Basset Hounds are friendly, outgoing, and playful dogs. They are also widely known for being stubborn.
They make great pets, especially for families with children, even though they are a bit hard to train.
Because of its gentle, non-confrontational nature, the Basset can be used for hunting in packs or alone.
They are extremely vocal and famously devoted to tracking.
This is a breed that requires exercise on a regular basis due to their ability to gain weight and be on the rather "lazy side." In fact, it is a necessary requirement, other than not being able to let the dog off the leash under any circumstances while they are being walked-the Basset will never respond to you while on a dead run after a scent or chasing something that runs. Walking them around the block just is not enough.
On February 27, 1928, Time magazine featured a basset hound on the front cover. The accompanying story was about the 52nd annual Westminster Kennel Club Dog Show at Madison Square Garden as if observed by the basset hound puppy.
Marquis de Lafayette brought Basset Hounds, to the United States as a gift to President George Washington to use in his hunting expeditions.
Basset Hounds are one of six recognised "basset"-type breeds in France.

Done On Bradstreet
Websites: http://doneonbradstreet.com/
Origin: Calgary, Alberta
In July of 1970 a well-known Calgary band named Done On Bradstreet was on the rise. They had been chosen by the promoters of Festival Express to open the Calgary stop on the tour and were slated to record their debut record with famed producer Norman Petty in Clovis, New Mexico. Done On Bradstreet had opened a number of big shows in the past but Festival Express was without a doubt the biggest. Sharing the stage with The Band, Janis Joplin and The Grateful Dead would be a career highlight for any band. The Festival Express proved to be a great testing ground for Done On Bradstreet's original material as the band was well received by fans and fellow musicians alike. The next step was to record this music. Done On Bradstreet made the 2000 km journey to Clovis just three weeks after their gig at Festival Express. Together they recorded six songs for their debut record under the guiding hand of Norman Petty. Unfortunately a series of Circumstances led to the band not hearing these recordings for 40 years. When the tape finally arrived 40 years after the recording sessions the band was thrilled to find that the music had stood the test of time. Done On Bradstreet now presents their debut recording, The Time Capsule.

Foreign, local firms vie for web-based broadcasting market in Korea
SEOUL, Jan. 9 (Yonhap) -- South Korea's mobile carriers and foreign technology firms are vying for the nation's growing market for Internet-based broadcasting services as people spend more time on their smartphones watching TV shows and movies.
While the so-called over-the-top content (OTT) broadcasting, which delivers video and other content via the Internet, is growing, some analysts say there is a long way to go before people embrace paid Internet broadcasting services.
Following the entry by an Internet TV network Netflix into the Korean market, U.S. video streaming services YouTube Red and Amazon's Prime Video also started business in the Korean market late last year.
The nation's three mobile carriers -- SK Telecom, KT and LG Uplus -- and Internet portals have offered Internet-based TV broadcasting, but only 4.7 percent of viewers subscribed to a paid service, according to data by the Korea Communications Commission.
However, the data showed that people are increasingly using their smartphones to watch TV.
In a survey by the commission of 7,385 people, unveiled late last year, 27.1 percent of the respondents said they used the OTT service.
In comparison, a 2015 survey showed that 14 percent used the OTT service.
Revenues for the Korean market for web-based broadcasting stood at 317.8 billion won (US$263.8 million) last year.
This year, the market is expected to jump 53.7 percent to 488.4 billion won, according to the commission's report.
YouTube was the most popular platform for Internet broadcasting, followed by Facebook; Naver's TV platform; AfreecaTV, a person-to-person video streaming website; and Daum's TV platform.
Paid web-based broadcasting services, run by KT, SK Telecom and LG Uplus, each accounted for about 1 percent of the total market, according to the data.
To increase their subscriber bases, companies have offered free services.
CJ E&M has provided a free live-streaming service of its 153 TV channels since last Tuesday.
Pooq, a TV app that broadcasts TV dramas and shows, is also expanding the scope of its free on-demand video streaming services.
An industry observer said OTT service providers aim to increase their subscriber bases with free services, while making efforts to make profits with ad revenues.

Yes, folks, it's 9/02/10, so all the fans of Beverly Hills, 90210 are celebrating 90210 Day. I can't think of a better day to celebrate.
I've seen every episode many times, I'm almost 41 years old and still have a mad crush on Dylan McKay (and a girl crush on Valerie Malone, what? She's hot!) I still think that Steve Sanders is the "original TV douche" after which all others were modeled yet pale in comparison. It's one of my favorite shows of all time, just slightly edged out of the top spot by Star Trek: The Next Generation.
Gawker TV has clips of their top 9 favorite moments. My favorite of all time made the list. That would be the prom/graduation two-parter, most popularly know as "Donna Martin Graduates!" A few of my other faves are missing like The Color Me Badd (Donna Martin's mother is a dirty cheater) episode, Kelly joining the cult and Dylan saving David from the DEA.
Were you a fan of 90201? Who was your favorite character, favorite episode? Will you be tuning in to the Labor of Love marathon on Monday? I know I will, for at least a few episodes. Somewhere, a few miles from here, my husband just shivered with dread but has yet to find out why.
Love it!! Thank you for bringing this to my attention! I so need a little Dylan time!
And seriously, is it really fair that Jenny Garth looks exactly the same how many years later?!?! Good for her!
And how fair is it that Jenny Garth looks exactly the same so many years later?!?! Good for her(I liked Kelli)!
I was a huge 90210 fan back in the day. I've never seen an episode of the new version though because it can't possibly compare. I had many fantasies about Dylan McKay. Happy belated 90210 Day!
Oh, so sorry I am late on this post. All I have to add is "Donna Martin Graduates!"
