Atomically Dispersed Mo–S Sites Boost NiFe–Layered Double Hydroxide for Industrial‐Level Seawater Electrolysis

Advanced Energy Materials, EarlyView.
(Mo–S)1@NiFe–LDH promotes the rapid structural transition to the active oxyhydroxide phase, enabling selective seawater oxidation at industrial‐level current densities. Atomically dispersed Mo–S sites within the LDH lattice efficaciously modulate the structural flexibility to lower the thermodynamic barrier for early‐phase activation.

SigmaFormer: Augmenting transformer encoders with COSMO sigma profiles for pure component property prediction

AIChE Journal, EarlyView.
Abstract Transformer‐based molecular models pretrained on SMILES strings demonstrate strong performance in property prediction. However, these model often lack explicit integration of molecular surface charge distributions that govern intermolecular interactions such as hydrogen bonding and polarity.

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
