Researchers make scalable arrays of building blocks for ultrathin electronics

Semiconductors, metals and insulators must be integrated to make the transistors that are the electronic building blocks of your smartphone, computer and other microchip-enabled devices. Today's transistors are miniscule--a mere 10 nanometers wide--and formed from three-dimensional (3D) crystals. But a disruptive new technology looms that uses two-dimensional...

Graphene nanoscrolls used in design of near-frictionless material

Argonne scientists used Mira to identify and improve a new mechanism for eliminating friction, which fed into the development of a hybrid material that exhibited superlubricity at the macroscale for the first time ("Macroscale superlubricity enabled by graphene nanoscroll formation"). Argonne Leadership Computing Facility (ALCF) researchers helped...

New study shows how nanoparticles can clean up environmental pollutants

Many human-made pollutants in the environment resist degradation through natural processes, and disrupt hormonal and other systems in mammals and other animals. Removing these toxic materials — which include pesticides and endocrine disruptors such as bisphenol A (BPA) — with existing methods is often expensive and time-consuming. In a new paper published...
