Nanowire Materials: From Synthesis to Applications

MSD Colloquium

Abstract: Nanowires are a group of one-dimensional structures that often show unique properties such as enhanced electrical, magnetic, and thermal properties in a preferred direction due to high length-to-diameter aspect ratios. Three-dimensional nanowire networks provide large surface areas, which can have superior catalytic properties. The specific attributes of nanowires have led to broad applications in multidisciplinary fields.

In this presentation, we report our nanowire development regarding a miniaturized RF device, a solid-state lithium battery electrolyte, and filtration membrane applications. Synthesis of nanowires by electrospinning and electroplating methods will be compared. In situ synchrotron-based small-angle X-ray scattering of electrospinning will also be discussed, which shows significantly reduced development time and cycles.

Bio: Yuepeng Zhang is a principal materials scientist with expertise in functional nanomaterials, thin films, and small-scale hybrid device development for RF and energy-storage applications. Her research experience includes roll-to-roll synthesis of nanowires and nonwoven structures, miniaturized RF components and devices, heat-assisted magnetic recording media, three-dimensional magnetic sensors, nanocomposite exchange-spring magnets, and magnetic shape memory thin films.
