Theory reveals the nature of crystals defects (of silicon carbide)

29 августа, 2019 - 17:26
Imperfections of crystal structure, especially edge dislocations of an elongated nature, deeply modify basic properties of the entire material and, in consequence, drastically limit its applications. Using silicon carbide as an example, physicists have shown that even such computationally demanding defects can be successfully examined with atomic accuracy by means of a cleverly constructed, small in size, model.

Nanotechnology and the concept of friction

29 августа, 2019 - 08:52
The precise mechanisms underlying friction at the nanoscale are still not completely understood. While gears, bearings, and liquid lubricants can reduce friction in the macroscopic world, the origins of micro-and nanoscale friction for small devices require other solutions. This primer explains the concept of friction, in nature and man-made systems, especially at the nanoscale. It then discusses a new class of 'smart' materials with the ability to modulate the friction of a surface.
