Plants and algae make their fuel from sunlight. Perhaps we could do the same using semiconductors. A team of scientists at ...
Insulators are materials in which electrons cannot move freely. Past theoretical studies predicted the existence of an unusual insulating state dubbed obstructed atomic insulator (OAI), in which ...
Using a new technique that can create vacancies at any site across a material and then shrink it to about 1/2,000 of its ...
Energy harvesting of all types generates significant interest and attention, as it has that aura of getting a little bit of ...
Scientists have developed two new covalent organic frameworks (COFs) that efficiently produce hydrogen peroxide — a valuable ...
Defect-engineered zinc oxide converts tiny reversible strains into near-infrared light, opening a rare-earth-free path to ...
Abstract: This article presents a globally optimized radio frequency (RF) energy harvesting system that leverages the novel concepts of 3-D maximum power point tracking (3-D MPPT) and collaborative ...
Abstract: A dual-band energy-selective surface (ESS) that achieves stealth for in-band and out-of-band electromagnetic (EM) waves is proposed in this article. It consists of an absorptive layer and a ...
