Switching on the future: Electronic switches on the molecular scale

A research team in Japan has shown that a molecular electronic switch with multi-conductance states (for example, high, medium and low states) is possible using a single quarter thiophene-based junction. In this new switch, the switching behavior is triggered by external mechanical force.

New materials for more powerful solar cells

Applying a thin film of metallic oxide significantly boosts the performance of solar panel cells. Researchers have developed a new class of materials comprising elements such as bismuth, iron, chromium, and oxygen. These multiferroic materials absorb solar radiation and possess unique electrical and magnetic properties.
