Craig has helped develop face shields and ventilators that have been drawn up and designed with advice from clinicians in hospitals and emergency rooms across Atlanta. And he is currently helping construct a foldable box that serves as a shield to protect healthcare workers while they perform intubations.
An unexpected property of nanometer-scale antimony crystals — the spontaneous formation of hollow structures — could help give the next generation of lithium ion batteries higher energy density without reducing battery lifetime. The reversibly hollowing structures could allow lithium ion batteries to hold more energy and therefore provide more power between charges.
Nestled in the constellation Taurus, a spectacle of swirling cosmic gases measuring half a dozen light-years across glows in shades of emerald and auburn. The Crab Nebula was born of a supernova, the explosion of a giant star, and now, a lab machine the size of a double door replicates how the immense blast paints these astronomical swirls into existence.
