Improving battery safety and efficiency for electric vehicles

As electric vehicles and personal portable electronics become more ubiquitous, researchers are trying to solve some of the major limitations of current lithium-ion battery technology, which uses a graphite anode and a lithium-based ...

Measuring Zak phase in room-temperature atoms

In topological insulators, global geometric phases of energy bands determine the existence of unidirectionally propagating edge states, which are immune to local defects, bringing a new stage for designing noise-resilient ...

The 'dense' potential of nanostructured superconductors

From superfast magnetic levitation trains and computer chips to magnetic resonance imaging (MRI) machines and particle accelerators, superconductors are electrifying various aspects of our life. Superconductivity is an interesting ...

Research improves upon conventional LED displays

LED lights have become ubiquitous lighting solutions for homes and businesses, but when it comes to large, high-resolution displays, traditional LEDs have documented disadvantages. LED displays use a high voltage and a factor ...
