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.
New research led by the University of Pittsburgh is poised to drastically improve the use of tracheal stents for children with airway obstruction. Researchers demonstrate for the first time the successful use of a completely biodegradable magnesium-alloy tracheal stent that safely degrades and does not require removal.
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.
A team led by Prof. YU Shuhong from the University of Science and Technology of China reported a bio-inspired lotus-fiber-mimetic spiral structure BC hydrogel fiber with high strength, high toughness, excellent biocompatibility, good stretchability, and high energy dissipation.
Computational materials science experts at the US Department of Energy's Ames Laboratory enhanced an algorithm that borrows its approach from the nesting habits of cuckoo birds, reducing the search time for new high-tech alloys from weeks to mere seconds.
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.
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.
The reproductive cycle of viruses requires self-assembly, maturation of virus particles and, after infection, the release of genetic material into a host cell. New physics-based technologies allow scientists to study the dynamics of this cycle and may eventually lead to new treatments.
