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.
Monoprinting is a form of printmaking that has lines or images that can only be made once, unlike most printmaking, where there are multiple originals. There are many techniques of monoprinting. Examples of standard printmaking techniques which can be used to make monoprints include lithography, woodcut, and etching.
