Smooth sailing for electrons in graphene
Physicists at the University of Wisconsin-Madison directly measured, for the first time at nanometer resolution, the fluid-like flow of electrons in graphene using a technique called scanning tunneling potentiometry.
Atom-thin walls could smash size, memory barriers in next-gen devices
Researchers led by the University of Nebraska-Lincoln demonstrated how to construct, control, and explain the oxygen-deprived walls of bismuth ferrite, a nanoscopically thin material suited to next-gen electronics.
ENERGY
Perovskites, a ‘dirt cheap’ alternative to silicon, just got a lot more efficient
University of Rochester researchers used a substrate made of either a layer of metal or alternating layers of metal and dielectric material—rather than glass—and found this change increased the perovskite’s light conversion efficiency by 250%.

What electrons can tell us about the speed of sand
A new sediment tracer uses the interactions between radiation, charge, and the sun to uncover the hidden transport histories of sand grains. This method offers a new tool to help answer large-scale questions of how Earth’s surface continues to change.
Silica glass guitar pick jazzes up UN International Year of Glass 2022
Researchers at Kyushu University debuted the world’s first silica glass guitar pick with a live performance at the UN IYOG 2022 closing ceremony. The pick was developed by professor Shigeru Fujino of Kyushu University’s Global Innovation Center, in collaboration with Kyoto Sangyo University, Ikeda Picks, and Kohoku Kogyo Co., Ltd.
