Scientists demonstrated that scanning photocurrent microscopy could provide the optoelectronic information needed to improve the performance of devices for power generation, communications, data ...

Inductors control electric current by using magnetic fields to resist sudden changes. This video explains how a simple coil can manage current flow and stabilize circuits in many electronic devices. A ...

The topic of electricity often poses difficulties for many secondary school students in physics lessons. Researchers have now developed and empirically evaluated a new, intuitive curriculum as part of ...

After a year of trial and error, Liyang Chen had managed to whittle down a metallic wire into a microscopic strand half the width of an E.coli bacterium — just thin enough to allow a trickle of ...
