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.
Monochrome means one color. Typically one color is presented in different values and intensities â or different shades of the single color. Monochrome is a phrase often associated with older computer system monitors. Monitors, for example, can be monochrome, grayscale or color. Monochrome monitors actually use two colors, one for the display image (the foreground) and one for the background. Graphic and digital images can also be monochrome, grayscale, or color. In photography a monochromatic image is usually in the form of a black and white photograph, which can be produced using black and white film or by removing colors in post-production.
