Light-emitting triangles may have applications in optical technology

For the first time, scientists have created single layers of a naturally occurring rare mineral called tungstenite, or WS2. The resulting sheet of stacked sulfur and tungsten atoms forms a honeycomb pattern of triangles that ...

New study gives insight into graphene grain boundaries

(Phys.org)—Using graphene – either as an alternative to, or most likely as a complementary material with – silicon, offers the promise of much faster future electronics, along with several other advantages over the ...

NASA investigates use of 'trailblazing' material for new sensors

Tiny sensors—made of a potentially trailblazing material just one atom thick and heralded as the "next best thing" since the invention of silicon—are now being developed to detect trace elements in Earth's upper atmosphere ...

Glass has potential to be stronger, researchers say

(Phys.org)—Glass is strong enough for so much: windshields, buildings and many other things that need to handle high stress without breaking. But scientists who look at the structure of glass strictly by the numbers believe ...

Every atom counts in graphene formation

(Phys.org)—Like tiny ships finding port in a storm, carbon atoms dock with the greater island of graphene in a predictable manner. But until recent research by scientists at Rice University, nobody had the tools to make ...
