Wavelike, collective oscillations of electrons known as “plasmons” are very important for determining the optical and electronic properties of metals. In atomically thin 2D materials, plasmons have an energy that is more useful for applications, including sensors and communication devices, than plasmons found in bulk metals. But determining how long plasmons live and whether their

Experts from the University of Surrey believe their dream of clean energy storage is a step closer after they unveiled their ground-breaking super-capacitor technology that is able to store and deliver electricity at high power rates, particularly for mobile applications. In a paper published by the journal Energy and Environmental Materials, researchers from Surrey’s Advanced

Insights into a flipping crystal could further research into the development of autonomous robots. Hokkaido University scientists have fabricated a crystal that autonomously flips back and forth while changing its flipping patterns in response to lighting conditions. Their findings, published in a Chemistry Europe’s journal, bring scientists closer to understanding how to build molecular robots

Allowing users to create objects from simple toys to custom prosthetic parts, plastics are a popular 3D printing material. But these printed parts are mechanically weak — a flaw caused by the imperfect bonding between the individual printed layers that make up the 3D part. Researchers at Texas A&M University, in collaboration with scientists in

Scientists at Japan’s Institute for Integrated Cell-Material Sciences (iCeMS) are leading efforts to synthesize stronger and efficient materials for hydrogen fuel cell membranes. Most fuel cells currently on the market employ liquid membranes. A new coordination polymer glass membrane, reported in the journal Chemical Science, works just as well as its liquid counterparts with added

BEER-SHEVA, Israel – May 12, 2020 – Ben-Gurion University of the Negev (BGU) researchers are developing safe, new anti-viral nanoparticle coatings that demonstrate significant potential in preventing active surface infection with SARS-CoV-2. The new coating could be used in hospitals and healthcare facilities as well as public locations such as schools, airports, trains, buses, and

Graphene is a diamagnetic material, this is, unable of becoming magnetic. However, a triangular piece of graphene is predicted to be magnetic. This apparent contradiction is a consequence of “magic” shapes in the structure of graphene flakes, which force electrons to “spin” easier in one direction. Triangulene is a triangular graphene flake, which possesses a
