A new study finds that robust superlubricity can be achieved using graphite and hexagonal boron nitride, which exhibit ultra-low friction and wear. This is an important milestone for future ...
Researchers have created microscale robots less than 1 millimeter in size that are printed as a 2D hexagonal 'metasheet' but, with a jolt of electricity, morph into preprogrammed 3D shapes and crawl.
