A new technique to change the structure of liquid crystals could lead to the development of fast-responding liquid crystals suitable for next-generation displays --...

Scientists put the “solve” in “solvent” for lithium-sulfur battery challenge

Lithium-ion batteries represent the majority of batteries in consumer electronics and electric vehicles. Today, scientists are looking for new chemistries that could improve the energy...

New device could provide cooling without electricity

Imagine a device that can sit outside under blazing sunlight on a clear day, and without using any power cool things down by more...

Kirigami inspires new method for wearable sensors

As wearable sensors become more prevalent, the need for a material resistant to damage from the stress and strains of the human body's natural...

Composite metal foam outperforms aluminum for use in aircraft wings

The leading edges of aircraft wings have to meet a very demanding set of characteristics. New research shows that a combination of steel composite metal...

Scientists achieve 30% power conversion efficiency for solar cells

In a recent study published in Nature Energy, Professor Michael McGehee and his team demonstrate how to dramatically improve the stability of tin-containing perovskite...

Scientists pinpoint cause of harmful dendrites and whiskers in lithium batteries

Scientists have uncovered a root cause of the growth of needle-like structures--known as dendrites and whiskers--that plague lithium batteries, sometimes causing a short circuit,...

How to control friction in topological insulators

Topological insulators are innovative materials that conduct electricity on the surface, but act as insulators on the inside. Physicists at the University of Basel and...
