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.
Our top performing printers â the Xerox ColorQube 8570, Xerox Phaser 3320 and Brother HL-L8350CDW â display all of the printing and cost-saving attributes that encompass an elite laser printer. Keep in mind that the Xerox Phaser is a monochrome printer and doesn't make color prints.
