Title: Nanocomposite particle synthesis using switchable ionic liquids (SWILs)
Dr. Nune, after his brief stay in Japan as JSPS postdoctoral fellow, he moved to University of Missouri-Columbia to work on the use of nanomaterials for biomedical applications. Before Joining PNNL, Dr. Nune was a postdoctoral research associate at the University of Kansas (KU) where he worked in a collaborative project between KU-Conoco-Phillips on the use of nanoparticles for enhanced oil recovery applications. His work has been highlighted in several external presses (National Cancer Institute; NCI, Royal Society of Chemistry; RSC), including Science Editorial Choice [Science 2008]. Dr. Nune currently is a research scientist working on the development of smart nanomaterials for gas storage, separation, sensing, delivery, and imaging applications.
Anisotropic nanomaterials such as nanowires and nanorods often exhibit interesting properties that are critical for designing devices with desired function. It is known that the solvent play a central role, impacting reaction rates, product separation, efficiency, and most importantly cost. Traditional solution based protocols offer flexibility such as the use of various surface protecting agents, reducing agents and solvents that generate huge solvent waste and are often energy intensive. Use of surfactants often results in materials containing nonmagnetic impurities that have impact during magnet fabrication ultimately resulting in economical and environmental burdens. On the other hand, switchable ionic liquids (SWILs) are a prime choice for solution-based FeConanocomposite synthesis, as SWILs can be used as soft templates that offer the ability to change the solvent and template in-situ. I will present our recent results obtained on the synthesis of nanoparticles using SWILs.
