Researchers built a fully functional, nanometer-sized transistor by using atomically flat, two-dimensional molybdenum disulfide semiconductor and a single-walled carbon nanotube imbedded in zirconium dioxide.
The way that nanoparticles behave in the environment is extremely complex. There is currently a lack of systematic experimental data to help understand them comprehensively, as environmental scientists have shown in a large overview study.
Researchers have proposed a new method of sensing gases based on a distinct optical fingerprint that arises in the presence of gas molecules. The research demonstrates a new principle which could lead to efficient gas sensors based on few-atom-thick transition metal dichalcogenides (TMDs).
