For nearly two decades, two-dimensional (2D) semiconductors have been studied as a complement or possible successor to silicon transistors, promising smaller, faster and more energy-efficient ...

Conventional crystals are materials in which atoms arrange themselves in repeating spatial patterns. Time crystals, on the other hand, are phases of matter characterized by repeating motions over time ...

Scientists developed a new method to convert carbon dioxide to methane with an electric field at low temperatures. In comparison to previous methods, this new method can produce any amount of methane ...

Optical materials are substances used to manipulate the flow of light. This can include reflecting, absorbing, focusing or splitting an optical beam. The efficiency of a specific material at each task ...
