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.
Scientists of Tomsk Polytechnic University jointly with colleagues from the University of Lille (Lille, France) synthetized a new material based on reduced graphene oxide (rGO) for supercapacitors, energy storage devices. The rGO modification method with the use of organic molecules, derivatives of hypervalent iodine, allowed obtaining a material that stores 1.7 times more electrical energy. The research findings are published in Electrochimica Acta academic journal (IF: 6,215; Q1).
Tsukuba University scientists describe the diffusion of sound in disordered materials, such as glass, using a new mathematical model. This work may lead to stronger and cheaper displays for touchscreen devices.
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.
A proposed hybrid-electric plane could "eliminate aviation's air pollution problem," say MIT engineers. Their design could reduce global nitrogen oxide (NOx) emissions by 95 percent, they report in a study.
Which demographic and socioeconomic factors were associated with patient participation in telehealth during the COVID-19 pandemic surge was examined in this observational study.
Lihong Wang demonstrates how his ultrafast camera technology might aid in the study of unpredictable systems.
