Machine learning analyses help unlock secrets of stable 'supercrystal'

Fri, 11/08/2019 - 14:21
Beyond solids, liquids, gases, plasma, and other examples only accessible under extreme conditions, scientists are constantly searching for other states of matter. Although newly discovered states tend to be short-lived, a recent experiment transformed a mixture of two materials into a novel state of matter with a much longer lifetime - a supercrystal.

Paving the way for inorganic perovskites' use in high-performance electronic applications

Thu, 11/07/2019 - 12:05
New work provides insight into the control over phase and ordering during halide perovskite epitaxial growth and expands the selection of photoactive materials for growing epitaxial halide perovskites that can be exploited in high-performance electronic applications. Hybrid organic-inorganic halide perovskite has attracted tremendous attention as an exceptional new class of semiconductors for solar harvesting, light emission, lasing and thin-film electronics. However, the toxicity of lead devices and lead manufacturing combined with the instability of organic components have been two key barriers to widespread application. Tin-based inorganic halide perovskites have been considered promising substitutes for their lead analogues.

Why is ice so slippery?

Tue, 11/05/2019 - 14:03
The answer lies in a film of water that is generated by friction, one that is far thinner than expected and much more viscous than usual water through its resemblance to the 'snow cones' of crushed ice we drink during the summer.
