Organic Solvent Nanofiltration (OSN)
Organic solvents play pivotal roles in the chemical, semiconductor manufacturing, and pharmaceutical industries. Across many processes, significant portions of the capital and operating costs are associated with the separation processes that deal with solvents. Because conventional separation processes such as evaporation, distillation, and extraction are highly energy-intensive, membrane-based separations are now becoming more attractive. Along these lines, the use of nanofiltration (NF) membranes for organic solvent separation has found a special place, and the field of “organic solvent nanofiltration” (OSN) has been evolving very rapidly. Among different types of membranes used for OSN, thin-film composite (TFC) and their derivative thin-film nanocomposite (TFN) membranes prepared via interfacial polymerization (IP) offer superior separation performance.

Supported Ionic Liquid Membranes
This project will serve as a fundamental investigation into the optimization of Supported Ionic Liquid Membranes (SILMs) and their use for capturing and sequestering Carbon Dioxide. SILMs are primarily comprised of a solvent, a polymer, and an ionic liquid, which is an ionic salt with a melting point below 100C. These often large and bulky salts feature a variety of characteristics that are desirable for Carbon Capture, including a high thermal stability, a low vapor pressure, and a negligible volatility. Ionic Liquids have only recently entered the sphere of application, so much optimization remains to find a sustainable alternative to the ecologically harmful carbon capture systems currently in place across the globe. Current efforts are being put towards investigating the ramifications of changing the polydispersity index of the polymer used in the solutions. This project hopes to push the limits of carbon capture and help develop a more sustainable industry.
Textile-based supercapacitors (TSCs)
Textile-based supercapacitors (TSCs) made by knitting yarn coated with conductive material into electrical circuits have many applications in the medicine, military, and consumer sectors. These devices are meant to collect and store energy from waste body heat and movement for delivery to personal electronic devices as a greener and more renewable alternative to Lithium-ion batteries that are currently used as a mobile power source. At PSE Bavarian Labs, we are the first group to successfully use wool as an electrode substrate in TSC research.

Summer Research Experience for Teachers (RET) Program
PSE Bavarian Labs participates in the summer Research Experience for Teachers (RET) program with the Nebraska Nanoscale Facility (NNF). This is a funded position for college community educators and high school teachers to participate in summer research activities in our lab. Participants can then turn their summer work into modules to teach their students during the academic year.
When: Mid-June until the end of July.
Applications are due in April.
