Researchers at the Cavendish Laboratory, University of Cambridge have demonstrated a new way to control radiation in the terahertz range—an often-overlooked part of the electromagnetic spectrum—with ...

Neuromorphic chips are the new hotness in semiconductor research. These chips consist of networks of transistors that interact the way neurons do, allowing them to process analog input, like visual ...

Effective control of terahertz radiation requires fast and efficient modulators with a large modulation depth—a challenge that is often tackled by using metamaterials. Metamaterial-based active ...

Graphene supercapacitors are moving from lab curiosity to serious contender for the next wave of electric vehicle energy storage. By pairing the near-instant charging of capacitors with the high ...

Graphene capacitors are both highly flexible and have an energy density far beyond existing electrochemical capacitors, possibly within reach of conventional lithium-ion and nickel metal hydride ...

A basic DVD writer was used to make graphene capacitors. These capacitors are thin, flexible, and potentially very inexpensive to manufacture, opening exciting possibilities for future electronics ...

Plasmonics is a subfield of nanophotonics involving the study of surface plasmon polaritons (SPP) 1,2,3. Quantum plasmonic nano-antennas have prominent applications in biosensing since they can ...

Consider an electric vehicle that takes only a few seconds to recharge while braking and then using that energy to power up the vehicle until the next stop. Imagine a lightweight smartphone that, ...

Obtaining useful work from random fluctuations in a system at thermal equilibrium has long been considered impossible. In fact, in the 1960s eminent American physicist Richard Feynman effectively shut ...
