Researchers have made a significant step toward breaking the so-called 'color barrier' of light microscopy for biological systems, allowing for much more comprehensive, system-wide labeling and imaging of a greater number of biomolecules in living cells and tissues than is currently attainable.
Scientists demonstrated that a vacancy in graphene can be charged in a controllable way such that electrons can be localized to mimic the electron orbitals of an artificial atom. Importantly, the trapping mechanism is reversible (turned on and off) and the energy levels can be tuned.
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).
