The team’s results are the first demonstration of an industrial, scalable method for manufacturing high-quality graphene that is tailored for use in membranes that filter a variety of molecules, including salts, larger ions, proteins, or nanoparticles. Such membranes should be useful for desalination, biological separation, and other applications.

In a world-first, an ESA-led team has built and fired an electric thruster to ingest scarce air molecules from the top of the atmosphere for propellant, opening the way to satellites flying in very low orbits for years on end.

A sandwich of two graphene layers can conduct electrons without resistance if they are twisted at a ‘magic angle’’, physicists have discovered. The finding could prove to be a significant step in the decades-long search for room-temperature superconductors.
