Single crystalline epitaxy of all inorganic lead-free halide perovskite paves the way for high-performance electronics

Thu, 03/29/2018 - 08:15
Halide perovskites have attracted tremendous interest due to their fascinating optoelectronic properties. Driven by the concerns of toxicity derived from lead and instability caused by organic components, researchers have turned to all-inorganic lead-free halide perovskites. However, compared to hybrid lead perovskite, lead-free compositions usually demonstrate poor crystallinity, low ordering, and high defects that suppress the performance of optoelectronic devices. Scientists now have deployed a new approach to grow all inorganic lead-free halide perovskites.

New technique accurately measures the water slippage in single graphene nanofluidic channels

Wed, 03/28/2018 - 05:24
For most viscous liquids, the solid surface of surrounding channel walls poses friction resistance to the flowing liquid, causing a loss of velocity at the liquid/solid interface. As a result, for regular surfaces the energy required for nanofluidic applications is enormous because of the tremendous hydraulic resistance inside nanoscale conduits. A new technique to accurately measure the hydraulic resistance inside graphene nanofluidic channels makes increasing the efficiencies of most nanofluidic applications possible.
