Researchers from the University of Illinois have developed a unique geometry of an electrodialysis system for enhanced efficiency of water purification. Electrodialysis can be inefficient due to concentration polarization of the ion depleted zone. The unique geometry of this technology increases the flux of purified water by removing current limiting regime in electrodialysis system.

Researchers at the University have created a system of UV disinfection using visible light lasers. The COVID-19 pandemic has vastly increased the need and urgency for effective and safe sanitation of large spaces including hospitals, public transportation, and meeting spaces. This fiber optic system tracks existing internal wiring and emits light via diodes that distribute ultraviolet light throughout a space to maximize disinfection. The UV light is emitted at a wavelength of less than 222 nm, making it safe for human contact. There are no lamps or filters required.

Dr. Miljkovic has developed microstructured aluminum (Al) tubes with increased heat transfer rates of 240% during refrigerant flow boiling. Highly conformal are generated by a scalable etching technique. The cost-effective techniques used to create etched-Al microstructures stand to significantly reduce manufacturing cost and time required for current enhancement approaches such as extrusion, drawing, and welding. At the same time increased performance is ensured on the thermal side. In addition, the fabricated etched structures are highly durable due to structure formation based on the base metal, and therefore do not suffer from thermal expansion coefficient mismatch issues, as is the case with other enhancements.

Professor Xiao Su and colleagues have developed an electrochemical system for the separation and reutilization of homogenous catalysts including Pt and Pd-cross coupling catalysts and many other noble metal homogenous catalysts. This catalyst recycling system allows for the direct capture of a homogenous catalysts from a reaction mixture, the captured catalyst can then be desorbed into a new reaction mixture. Notably, this catalyst capture and release system operates without chemically altering the catalyst species thus this system maintains the original catalyst activity. This electrochemical system utilizes redox polymer electrodes allowing for the >99% catalyst adsorption within a 5-minute period. The adsorption properties of this system can be easily adjusted by modifying the applied current and electrode dimensions. Furthermore, >99% of the catalyst adsorbed can be released from the redox electrodes resulting in a highly efficient catalyst recycling system.

Researchers have developed a dry surface and shape adaptive thin shape memory polymer adhesive specifically targeting flexible fabric adherends. Current temporary or permanent adhesives for lightweight fabrics lack reusability, shape and surface adaptability. The invention uses unique characteristics of shape memory polymer to create a surface and shape adaptive adhesive that leaves no residue, can be reused, is washable and has high holding strength. The primary application of this invention will be to use as thin flexible adhesive for fabrics.
