Atomic 'Swiss Army Knife' precisely measures materials for quantum computers

Nanowerk.com - 5 hours 13 min назад
Scientists have developed a novel instrument that can make three kinds of atom-scale measurements simultaneously: It images single atoms. It maps atomic-scale hills and valleys on metal and insulating surfaces. And it records the flow of current across atom-thin materials subject to giant magnetic fields.

Fast-charging and high-capacity nanomesh-based cathodes for Li-ion batteries

Nanowerk.com - 6 июля, 2020 - 16:07
The concept of nanostructuring of battery electrodes is not new; it has been frequently employed to improve the charging speed and, in some cases, stability of Li-ion electrodes. Researchers now demonstrated 3D-interconnected Ni nanowire meshes as current collectors and structural scaffolds for building nanostructured Li-ion electrodes. This material exhibits a semi-ordered structure and is characterized by some of the highest combined porosity and surface-to-volume ratio among macroporous metals.
