A Conserved Isoleucine Gates the Diffusion of CO and O2 to the Active Site of NiFe CO‐Dehydrogenase

Angewandte Chemie, EarlyView.
A combination of protein film electrochemistry and site‐directed mutagenesis shows that isoleucine 563 (numbering of Thermococcus sp. AM4) gates the arrival of both CO and O2 to the active site of the nickel‐iron CO dehydrogenases. Mutations at this position increase the resistance to O2 at the cost of a slower reaction with CO.

Direct Observation of Radical‐Mediated Oxide‐to‐Alloy Transformation in Solution Under Pulsed Laser Irradiation

Angewandte Chemie, EarlyView.
Time‐resolved in situ x‐ray absorption spectroscopy and DFTB‐based molecular dynamics simulations identify direct hydrogen atom transfer from ethanol to lattice oxygen as the elementary step of laser‐driven reduction in NiCo2O4. While this transfer is facile, the subsequent release of lattice oxygen is entropy‐driven and becomes accessible only at ...

Dissipative Regenerative Chemiluminescence in Water: A Perylene‐Based Out‐of‐Equilibrium Light‐Emitting System

Angewandte Chemie, EarlyView.
Driven by sodium dithionite and hydrogen peroxide under mild aqueous conditions, a water‐soluble perylene bisimide undergoes reversible electron‐transfer cycles that generate its emissive excited state without dye decomposition. We define this out‐of‐equilibrium system as chemically fueled regenerative chemiluminescence (CFRCL), opening new avenues for
