Glimpse inside a graphene sandwich

In the search for novel types of superconductors — phases of matter that that conduct electric current without loss — scientists are investigating materials that consist of multiple layers. A team has studied in detail the properties of a system of three twisted graphene layers and gained important insights into its properties. Since the first…

Disposable masks could be used to improve concrete

With the pervasive single-use masks during the pandemic now presenting an environmental problem, researchers have demonstrated the idea of incorporating old masks into a cement mixture to create stronger, more durable concrete. In a paper published in the journal, Materials Letters, a Washington State University research team showed that the mixture using mask materials was…
