Rare earth elements used in smartphones and electric vehicles could be extracted from the ground more sustainably using electric fields. Today, most rare earth metals used in electronics are mined ...

The phase and the group velocity of light propagating in conventional optical media cannot exceed the speed of light in vacuum. However, in so-called epsilon-near-zero (ENZ) materials, light ...

Their study, published in Nature, reveals how electric field effects can selectively accelerate coupled electrochemical processes in graphene. Electrochemical processes are essential in renewable ...

The new research focuses on the ambipolar electric field which was first theorised over 60 years ago by NASA's suborbital Endurance rocket, with scientists wanting to explore how the planet's ...

The aim of this module is to teach you the basic laws of electric and magnetic fields, their application to elementary problems involving steady and time changing fields and currents, and give you an ...

How an applied electric field for medical electrotherapy speeds wound healing. Creation of the self-powered, non-electronic electrotherapy patch. Results of the electrical and medical performance ...
