wo-dimensional materials can be used to create smaller, high-performance transistors traditionally made of silicon, according to Saptarshi Das, assistant professor of engineering science and mechanics (ESM) in Penn State's ...
Seen from space, the Earth is blue. The Earth has been blue for over 4 billion years because of the liquid water on its surface. How has the Earth managed to sustain liquid water on its surface for such a long time?
While chlorine and ultraviolet light are the standard means of disinfecting water, ozone is equally effective in killing germs. To date, ozone has only been used as an oxidation agent for treating water in large plants. Now, ...
Ocean pollution is widespread, worsening, and poses a clear and present danger to human health and wellbeing. But the extent of this danger has not been widely comprehended—until now. Our recent study provides the first comprehensive ...
Russian researchers have proposed a new method for synthesizing high-quality graphene nanoribbons—a material with potential for applications in flexible electronics, solar cells, LEDs, lasers, and more. Presented in The Journal ...
Stimuli-responsive, self-folding, two-dimensional (2-D) layered materials have interesting functions for flexible electronics, wearables, biosensors, and photonics applications. However, limits with scalability and a lack ...
With only about 50 million miles (80 million kilometers) left to go in its 293-million-mile (471-million-kilometer) journey, NASA's Mars 2020 Perseverance rover is nearing its new planetary home. The spacecraft has begun ...
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, ...
Rapid, accurate communication worldwide is possible via fiber optic cables, but as good as they are, they are not perfect. Now, researchers from Penn State and AGC Inc. in Japan suggest that the silica glass used for these ...
New periodic structures known as moiré lattices can be observed in two-dimensional (2-D) heterostructures containing layers with slightly different lattice vectors, which can in turn support new topological phenomena. It ...
