Dec 25, 2020 (Nanowerk News) Light travels at a speed of about 300,000,000 meters per second as light particles, photons, or equivalently as electromagnetic field waves. Experiments led by Hrvoje Petek, an H.K. Mellon professor in the Department of Physics and Astronomy examined ideas surrounding the origins of light, taking...
Record-setting thermoelectric figure of merit achieved for metal oxides
Dec 23, 2020 (Nanowerk News) Waste heat is a highly promising source of renewable energy; however, the efficiency of using heat to generate energy has historically been much lower than hydroelectric, wind or solar power. While there are a number of materials that can be used for the generation of...

Atomic-scale nanowires can now be produced at scale
Dec 24, 2020 (Nanowerk News) Researchers from Tokyo Metropolitan University have discovered a way to make self-assembled nanowires of transition metal chalcogenides at scale using chemical vapor deposition. By changing the substrate where the wires form, they can tune how these wires are arranged, from aligned configurations of atomically thin...
