Physicists from the Moscow Institute of Physics and Technology and the Institute for High Pressure Physics of the Russian Academy of Sciences have used computer modeling to refine the melting curve of graphite that has been studied for over 100 years, with inconsistent findings. They also found that graphene “melting” is in […]

Abstraction. Credit: Daria Sokol/MIPT Press Office Researchers from the Moscow Institute of Physics and Technology, Kotelnikov Institute of Radio Engineering and Electronics, and N.G. Chernyshevsky Saratov State University have demonstrated that the coupling elements in magnonic logic circuits are so crucial that a poorly selected waveguide can lead to signal […]

This image, magnified 25,000 times, shows a section of a prototype accelerator-on-a-chip. The segment shown here are one-tenth the width of a human. The oddly shaped gray structures are nanometer-sized features carved in to silicon that focus bursts of infrared laser light, shown in yellow and purple, on a flow […]

Light makes the conditioned liquid crystal move. Credit: Aalto University, Tampere University, Cell Press Researchers trained material the same way as Pavlov trained dogs. Conditioning is a method made famous by Ivan Pavlov’s experiments with dogs. Pavlov trained a dog by ringing a bell every time the dog was fed. […]

Engineers have characterized the thermal energy conversion mechanism in the lattice of an advanced nanomaterial called chalcogenide perovskite and demonstrated its ‘tunability’ — important for its potential use in solar energy generation. For solar cells to be widely used in the coming decades, researchers must resolve two major challenges: increasing […]
