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.

Read More 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.

This enables his design to improve current electrode performance by a factor of 1000. Furthermore, Dr. Smith has improved the shape and arrangement of his flow channels by arranging them in a hierarchical fashion and creating a cube-root shape. This results in an optimized and improved flow channel that makes the electrodes much more permeable than current designs. Effectively, these electrodes can now have a flow with very low amounts of pressure required.
