New Water Oxidation Mechanism in Photosystem II Resolves Major Experimental Controversies

Angewandte Chemie, EarlyView.
In Photosystem II Oxygen Evolving Complex, we discovered the O3‐O6 peroxide at lower energy. Assignment of the O3 ligated by histidine (His337) as a slow exchanging substrate and its coupling with O6 give the O─O bond formation mechanism most consistent with all currently available experimental data. Proposal shows how protein environment can steer the

Piezoelectric Nanocomposite Hydrogel for Wireless Neural Stimulation and Tissue Augmentation

Advanced NanoBiomed Research, EarlyView.
A cell/tissue supporting piezoelectric hydrogel system (PZ‐gel) that incorporates ferroelectric, pyroelectric, and piezoelectric ceramic material barium titanate into an alginate/carboxymethyl chitosan hydrogel. The PZ‐gel can be sonoactivated for wireless neural cell and tissue stimulation, with the potential to be used as a stimulatory cell substrate

Structural and Functional Siderophore Remodeling by Enzymatic Delipidation

Angewandte Chemie, EarlyView.
A surprising functional switch in bacterial siderophores was discovered through genome mining and the analysis of environmental and pathogenic Pandoraea species. Pandorachelin B, a lipocyclopeptide that promotes swarming motility, is cleaved by a specialized acylase, yielding a ring‐contracted, homodetic cyclopeptide, pandorachelin A, which exhibits ...

Solvent Hydrogen Bonding Determines Adsorption Geometry of Trimesic Acid on Cu

Angewandte Chemie, EarlyView.
Water reorients adsorbate molecules. Combined tip‐enhanced Raman spectroscopy, density functional theory and molecular dynamics simulations reveal the adsorption geometry of trimesic acid on Cu. Subtle adsorbate–substrate–solvent energy differences due to hydrogen bonding dictate molecular orientation at solid/liquid and solid/gas interfaces, providing
