Abstract : 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 electrolyte/electrode 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.
