This report details the procurement and integration of an infrared IR spectrometer Thermo Scientific - Nicolet iS50R Spectrometer intoour electrochemistry program. The instrument is being utilized to characterize ionic liquid-based IL-based electrolyte systems viasimultaneous electrochemical and spectroscopic studies. These studies are enabling us to understanding the microscopic molecular andionic dynamics at electrolyteelectrode interfaces. This information is important for the development of enhanced energy conversionprocesses and devices e.g., supercapacitors. The Nicolet iS50R spectrometer has been synchronized with a potentiostat to perform surfaceenhanced infrared absorption SEIRA spectroscopy during electrochemical voltammetric perturbation. The spectrometer has also beenutilized to help us characterize biomaterials before and after processing in a separate project that aims to create robust, functionalbiocomposites. In particular, we are interested to develop tough bio-based composites for energy storage and water remediationapplications. Sample data from these ongoing efforts are demonstrated in this report.
