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).
In a newly published study, the shape and geometry of nanoparticles can have a significant impact in modulating adverse injection reactions and offer realistic solutions for patients receiving nanopharmaceuticals.
Using pressure instead of chemicals, a team has fabricated nanoparticles into nanowire-array structures similar to those that underlie the surfaces of touch-screens for sensors, computers, phones and TVs.
