Elucidating Sodium Ion Storage Mechanisms in Hard Carbon Anodes at the Electronic Level

Advanced Functional Materials, EarlyView.
High‐resolution, multi‐frequency continuous wave, and pulsed Electron Paramagnetic Resonance (EPR) spectroscopy uncover the intricate Na ion storage mechanisms in hard carbon. This study reveals the coexistence of Na ion intercalation and solvent co‐intercalation, alongside a subsequent transition of Na ions from ionic to quasi‐metallic to metallic ...

Punching Holes in an Enzyme

Chemistry & Biology, 2009
Schramm and coworkers have punched holes into human purine nucleoside phosphorylase by substitution of glycine for aromatic amino acid residues at a protein lid. The results of studies on the enzymes with holes illuminate hidden chemistry that occurs at the enzyme active site.
