Researchers at the University at Buffalo have discovered a new, two-dimensional transistor that is made of graphene and the compound molybdenum disulfide and could help usher in a new era of computing. The transistor requires half the voltage of current semiconductors and has a current density greater than similar transistors under development.

Scientists at Columbia University and the University of Glasgow have discovered a new chemical design principle for exploiting destructive quantum interference. The scientists used their approach to create a six-nanometer single-molecule switch in which the on-state current is more than 10,000 times greater than the off-state current. They demonstrated that this approach can be used to produce stable and reproducible single-molecule switches at room temperature that can carry currents exceeding 0.1 microamp in the on state.

An international team of researchers, led by scientists at Penn State, found that arranging micro-supercapacitor cells in a serpentine, island-bridge layout allows the configuration to stretch and bend at the bridges, while reducing deformation of the micro-supercapacitors. The researchers used non-layered, ultrathin zinc-phosphorus nanosheets and 3D laser-induced graphene foam – a highly porous, self-heating nanomaterial – to construct the island-bridge design of the cells and noticed that these micro-supercapacitor arrays can charge and discharge efficiently and store the energy needed to power a wearable device.

Researchers at Rice University have identified a novel, second level of fluorescence by carbon nanotubes. The Rice University team discovered that single-walled nanotubes emit a delayed secondary fluorescence when triggered by a multistep process in a solution with dye molecules and dissolved oxygen. Potential applications for the findings include optoelectronics and solar energy developments.

Scientists at Washington State University have used human white blood cell membranes to carry two drugs, an antibiotic and an anti-inflammatory, directly to infected lungs in mice. The nano-sized drug delivery method successfully treated both the bacterial growth and inflammation in the mice's lungs. The study shows a potential new strategy for treating infectious diseases, including COVID-19.
