For several decades, physicists have known that light can be described simultaneously as a wave and a particle. This fascinating 'duality' of light is due to the classical and quantum nature of electromagnetic excitations, ...
Recent advances in smart contact lenses can assist biomedical engineers to realize medical applications and vision imaging for augmented reality with wireless communication systems. Previous research on smart contact lenses ...
(Phys.org) —There has been a great deal of research lately on flexible electronics, but so far these devices (which are mostly made of carbon) still use metal electrodes and oxide insulators, and these rigid materials limit ...
(Phys.org) —In today's wireless communication systems, the wireless signals are non-chaotic, meaning they have a well-defined period and frequency. Non-chaotic wireless signals are used in many applications, such as satellite ...
Electrons find each other repulsive. Nothing personal—it's just that their negative charges repel each other. So getting them to pair up and travel together, like they do in superconducting materials, requires a little ...

(Phys.org) —It was a big week for discovery as a Star Trek-like invisible shield was found thousands of miles above Earth—it's in the Van Allen radiation belt and appears to protect the planet below from "killer electrons." ...
(Phys.org) —A team of researchers studying comet Lovejoy has discovered that as the ball of ice passed through the sun's corona in December 2011, its tail wiggled in a way that allowed them to better understand coronal ...
Physicists at The University of Texas at Austin, in collaboration with colleagues in Taiwan and China, have developed the world's smallest semiconductor laser, a breakthrough for emerging photonic technology with applications ...
