Copper blasted into a million-degree plasma strips away 22 electrons in a flash before atoms recover

When laser flashes hit matter, electrons are knocked off their orbits around the atomic nuclei. This can generate extremely hot plasmas composed of charged particles—ions and electrons. Researchers at ...

Laser‑driven single‑step synthesis of monolithic prelithiated silicon‑graphene anodes for ultrahigh‑performance zero‑decay lithium‑ion batteries

We report an ambient single-step laser-driven process that simultaneously synthesizes and integrates prelithiated silicon nanoparticles into a robust graphene matrix using simple precursors.
