New Graphene-Based System Could Help Us ‘See’ Electrical Signaling in Heart and Nerve Cells

Image - This diagram shows the setup for an imaging method that mapped electrical signals using a sheet of graphene and an infrared laser. The laser was fired through a prism (lower left) onto a sheet of graphene. An electrode was used to send tiny electrical signals into a liquid solution (in cylinder atop the graphene), and a camera (lower right) was used to capture images mapping out these electrical signals.

Scientists Find Twisting 3-D Raceway for Electrons in Nanoscale Crystal Slices

Photo - A scanning electron microscope image shows triangular (red) and rectangular samples of a semimetal crystal known as cadmium arsenide. The rectangular sample is about 0.8 microns (thousandths of a millimeter) thick, 3.2 microns tall and 5 microns long. The triangular sample has a base measuring about 2.7 microns. The design of the triangular samples, fabricated at Berkeley Lab’s Molecular Foundry, proved useful in mapping out the strange electron orbits exhibited by this material when exposed to a magnetic field.
