Icosahedral Crown Gold Nanocluster Au₄₃Cu₁₂ with High Catalytic Activity

, 2016
Structural and catalytic properties of the gold alloy nanocluster Au43Cu12 are investigated using a density-functional method. In contrast to the pure Au55 nanocluster, which exhibits a low-symmetry C1 structure, the 55-atom “crown gold” nanocluster ...

Deposition Rate‐Controlled Functional Evolution of p‐Type Selenium‐Alloyed Tellurium–Tellurium Oxide Films for Thin‐Film Transistors

Advanced Science, EarlyView.
This study investigates the effects of thermal deposition rate on next‐generation p‐type amorphous oxide semiconductor SeTe–TeOx films. Deposition rate governs the chemical states, microstructure, and electrical characteristics of the films, resulting in tunable device properties.

Potential‐Controlled Ammonium‐Assisted Reversible Electrodeposition of Polyoxometalates for Hybrid Redox Flow Batteries

Advanced Science, EarlyView.
Potential‐controlled NH4+‐assisted reversible electrodeposition of molecular metal oxide clusters enables dynamic solution‐to‐solid electron storage. Leveraging this deposition/dissolution reaction chemistry, polyoxometalate‐based hybrid flow batteries are demonstrated as a new platform for deposition‐based electrochemical energy storage.

High‐Current‐Density Acidic CO2 Electroreduction to Formic Acid Enabled by Multiscale Microenvironment Regulation Over Defect‐Rich Sn/SnOx

Advanced Science, EarlyView.
Acidic CO2 electroreduction to formic acid is enabled by integrating mixed Sn/SnOx nanoclusters, K+‐regulated interfacial solvation, and Janus wettability. Coordinated control of active sites, interfacial water, and gas‐liquid transport suppresses hydrogen evolution and delivers approximately 85% HCOOH Faradaic efficiency at 400 mA cm−2.

Synergistic Integration of Fe–N4 Single‐Atom Sites and Directionally Aligned Electrode Architecture for High‐Performance Lithium–Sulfur Batteries

Advanced Science, EarlyView.
A directionally ice‐templated sulfur cathode integrated with atomically dispersed Fe–N4 catalytic sites is developed for high‐performance lithium–sulfur batteries. The structure–catalysis synergy accelerates Li+ transport and polysulfide conversion, leading to high sulfur utilization and stable long‐term cycling performance.
