In groundbreaking materials research, a team led by University of Minnesota Professor K. Andre Mkhoyan has made a discovery that blends the best of two sought-after qualities for touchscreens and smart windows--transparency and conductivity.

JST PRESTO researcher developed a MEMS resonator that stably operates even under high temperatures by regulating the strain caused by the heat from gallium nitride (GaN). This device is small, highly sensitive and can be integrated with CMOS technology promising for the application to 5G communication, IoT timing device, on-vehicle applications, and advanced driver assistance system.

Although magnesium diboride (MgB2) is an interesting superconductor made from abundant materials, increasing its critical current density through easily accessible means has proven challenging. In a recent study, scientists form Shibaura Institute of Technology, Japan, used ultrasonication to turn cheap commercial boron into a fine powder. With it, bulk MgB2 with enhanced superconducting properties can be produced, paving the way to affordable superconducting magnets for medical and transportation applications.

The software was developed by the University of Trento. It is a new and revolutionary method to manage the accommodation of guests in hotel. RoomTetris finds the best solution, the ideal combination between demand and supply, optimizing room occupancy. A tile-matching game that no human mind, no matter how experienced and skilled, could do better, with the seriousness and scientific rigor of a mathematical demonstration

Gaining control of the flow of electrical current through atomically thin materials is important to potential future applications in photovoltaics or computing. Physicists in Arts & Sciences at Washington University in St. Louis have discovered one way to locally add electrical charge to a graphene device.

Lihong Wang demonstrates how his ultrafast camera technology might aid in the study of unpredictable systems.
