TEM (a, b, and c) images of prepared mesoporous silica nanoparticles with mean outer diameter: (a) 20nm, (b) 45nm, and (c) 80nm. SEM (d) image corresponding to (b). The insets are a high magnification of mesoporous silica particle.
The Definition of a Monochrome Laser Printer. Monochrome laser printers are machines that print text and images from computers by using a laser beam to control where a single color is applied to paper. They're often faster than other types of printers and can generally produce large numbers of black-and-white documents cheaper than other printers.
Note: To keep the print head clear and ready to print, the printer uses a small amount of ink from all the cartridges whenever it prints. Even if you select Black/Grayscale or Grayscale, some color ink is still being used. Black/Grayscale or Grayscale is not recommended for printing black-and-white photos.ote: If you don't see these buttons, click Setup, Printer, or Options, then click Properties or Preferences on the next screen. 1  Click the Main or Advanced tab. 2  Select Black/Grayscale under Print Options.
