Advanced Functional Materials, EarlyView.Single‐crystal gold microplates are high‐performance nanomaterials with an impressive wafer‐based application space. Progress has, however, been tempered by an inability to exert synthetic control over microplate size, shape, and positioning. In this work, control over these parameters is demonstrated using a seed‐mediated synthesis that both confines ...

Synthesis and characterization of nano iron nitrides for application in hydrazine decomposition
, 2006 Nano iron nitrides were prepared from different nano iron oxides by Temperature-Programmed Reaction (TPR). It was found that the nano iron oxide prepared from homogeneous precipitation could yield 50~100 nm iron nitride.
