A team led by scientists at the Department of Energy’s Oak Ridge National Laboratory explored how atomically thin two-dimensional (2D) crystals can grow over 3D objects and how the curvature of those objects can stretch and strain the
Ionic conduction involves the movement of ions from one location to another inside a material. The ions travel through point defects, which are irregularities in the otherwise consistent arrangement of atoms known as the crystal lattice.
The lighter wand for your gas BBQ, a submarine’s sonar device and the ultrasound machine at your doctor’s office all rely on piezoelectric materials, which turn mechanical stress into electrical energy, and vice versa.
Catalysts make chemical reactions more likely to occur. In most cases, a catalyst that’s good at driving chemical reactions in one direction is bad at driving reactions in the opposite direction.
