Amorphous nanomaterials, with unique structural features such as long-range atomic disorder and nanoscale particle or grain sizes, possess some advantageous properties for a number of materials applications. For example, amorphous vanadium oxide exhibits a record-high cycling stability for supercapacitors. Several synthetic strategies have been developed to produce amorphous nanomaterials, such as physical processing-based approaches including cutting, deposition, and spinning, as well as chemical syntheses by solution or solid state reactions. However, despite the rapid development of amorphous nanomaterials, their morphology is still irregular or primarily sphere-like. The limited morphology control is partially attributed to the lack of preferred growth direction for the amorphous materials. It will be interesting to know whether different morphologies of even amorphous nanomaterials can influence their properties as much as their crystalline counterparts.
