Site‐Specific Hydroxide Formation and Corrosion on Mg Nanocrystals

Advanced Science, EarlyView.
Using single‐crystalline Mg nanocrystals, this study uncovers the intrinsic corrosion initiation mechanism. The stability of the protective Mg(OH)2 film depends on its interfacial coherence with the Mg substrate. Corrosion initiates at exposed corners, where film coverage is incomplete.

Tailored Catalytic Microenvironments Enable Efficient Electrochemical Ammonia Production

Advanced Science, EarlyView.
This study shows that Co2+ substitution in inverse spinel FeFeCoO4 constructs an integrated catalytic microenvironment for efficient nitrate‐to‐ammonia reduction. Jahn–Teller distortion activates Fe sites for *H generation, while hard–soft acid–base regulated dual‐metal sites optimize proton‐coupled electron transfer and intermediate adsorption ...

Enhancing Li‐S Battery Performance Through Low‐Concentration Electrolytes with Organic Se/Te Co‐Additives to Address Solubility and Kinetic Challenges

Advanced Science, EarlyView.
This work presents a low‐concentration electrolyte enabled by hybrid organic Se/Te additives (DPDSe/DPDTe) that restructures solvation, boosts polysulfide dissolution, and provides dual‐site synergistic catalysis, delivering high capacity and stable cycling in Li–S coin and pouch cells, supporting high‐energy, high‐power operation.
