Dr. John Schaibley, associate professor of physics, explains how to use an ultrafast white light laser to study two-dimensional semiconductor devices. His group fabricates and studies three-atom-thick electronic devices for future applications to ultra-high-speed and low-energy consumption computers that use quantum effects like electron spin. These ultra-thin and highly tunable materials also have applications to nanoscale voltage sensing, which can be used for microchip authenticity verification. To purchase the Supercontinuum laser (red box in image) Dr. Schaibley’s team won an instrumentation award of $250K from UArizona Research, Innovation & Impact. The team needs $79K more to make the purchase.

Standing next to a large 3D printer for metal alloys, Dr. Andrew Wessman, Materials Science & Engineering, describes the benefits of additive manufacturing over traditional metal forming processes. These include more efficient utilization of expensive materials, the possibility of combining multiple small parts into a single 3D printed structure, and the ability to create structures with complex geometries not producible with other methods such as aerostructures with integral cooling channels. These benefits can provide significant advantages for building hypersonic vehicles with excellent performance in challenging high temperature conditions.

The Arizona Polysonic Wind Tunnel (APWT) features a 15x15 inch test section. It is the largest polysonic facility operated by a U.S. university. Polysonic wind tunnels can operate at subsonic, transonic, supersonic and hypersonic speeds.

Graduate students and staff in the Department of Aerospace and Mechanical Engineering at the University of Arizona have been setting up a control room for the Arizona Polysonic Wind Tunnel (APWT). This allows the operator to run the wind tunnel remotely using computer control.
