Dr. Boppart has created a new manner of calibrating multimodal optical instruments. Unlike prior solutions, such as fluorescent beads, this invention does not bleach and can be used calibrate instruments across multiple frames longitudinally. This solution can also be used to normalize imaging data and is able to calibrate instruments for 2D and 3D multimodal instruments so that standardized imaging under realistic, tissue-sample-like settings can be achieved.

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.

Researchers have developed a novel design strategy that mitigates the formation of vortices across the rotor near-wake region. The unique design aims to reduce thrust distribution across the tip region in order to mitigate the formation of energetic, coherent vortices at the blade tip. The invention features a unique geometrical rotary wing design that creates zero vortices at the wingtip allowing noise reduction generated by blade-vortex interactions. This invention could be used for lifting rotors or propellers on standard helicopter flight vehicles, other vertical lift aircraft, and turbines with minimal effect in total rotor efficiency.

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.

Dr. Rakesh Kumar and his team have developed a new system and tool to analyze logic circuits and find opportunity to automatically optimize them. This technology automatically identifies unused instructions from microprocessors that an application is guaranteed not to exercise, eliminates these components and optimizes the design to reduce their cost, area and power requirement. This system uses a combination of techniques that differ from prior methods and leads to improved results. Instead of adding instructions to a specific design, it automatically removed unused ones and generates enhanced hardware from arbitrary designs.

Researchers at the University of Illinois have developed ultra-flexible heterostructures made from 2D layers of van der Waals bonded materials. The heterostructures retain the optoelectronic properties of their constituent layers, but offer tunable mechanical properties which can include flexibility rivaling that of lipid bilayers. Applications for this technology include MEMS devices and flexible, stretchable, and conformal circuitry, including reconfigurable 2D devices and folded/curved/crumpled nanostructures.

Researchers from the University of Illinois have developed a platform for stretchable + flexible optoelectronics that offer consistent performance in stretched vs. non-stretched mode. The platform, which features stacked layers of two-dimensional materials that are crumpled or wrinkled, can enable new designs and manufacturing methodologies for devices that offer both toughness and malleability at scales as small as nanometers.

Researchers at the University of Illinois have developed a three-dimensional high electron mobility transistor (HEMT) architecture that utilizes ultra-wide bandgap (UWBG) materials. These structures and devices can be used for high-power, high-frequency applications, where they can confer an order of magnitude higher performance than wide bandgap (WBG) devices, including simultaneously achieving 10x higher power density while operating at frequencies as high as 120 GHz.
