Borohydride electrochemical oxidation on carbon-supported Pt-modified Au nanoparticles

, 2010
The carbon-supported Pt-modified Au nanoparticles were prepared by two different chemical reduction processes, the simultaneous chemical reduction of Pt and Au on carbon process (A-AuPt/C) and the successive reduction of Au then Pt (B-AuPt/C) on carbon ...

Shaping Matter with Acoustic Waves: From Particles to Functional Structures

Advanced Functional Materials, EarlyView.
Acoustic‐directed assembly is reviewed as a materials‐oriented strategy for organizing particles, polymers, metals, and biological systems into functional structures. The review distinguishes reversible manipulation from permanent structure formation through medium fixation, particle fixation, and in situ material generation, highlighting routes toward

Phase Engineering of Atomically Precise Nanoclusters (APNCs) of Gold and Beyond

Advanced Materials, EarlyView.
Engineering the structural phase of materials is of paramount importance for both fundamental research and practical applications. In this Review, we summarize the recent progress in controlling the phases of atomically precise nanoclusters (APNCs) of gold, silver and copper, as well as bimetallic systems. The phase‐enabled material properties of APNCs

Design of High‐Energy Anode for All‐Solid‐State Lithium Batteries–A Model with Borohydride‐Based Electrolytes

Advanced Materials Interfaces, EarlyView.
This study proposes a function‐sharing anode design to enable nonmetallic lithium insertion while maintaining intimate interfacial contact with the solid‐state electrolyte. A combination of lithium‐compatible and conformable borohydrides, highly conformable indium metal, less‐graphitized acetylene black, and a layer of highly graphitized massive ...
