Nanocrystals store light energy and drive chemical reactions

Chemistry is increasingly making use of the trick plants can do with photosynthesis: driving chemical reactions that run poorly or do not occur spontaneously at all with light energy. This requires suitable photocatalysts ...

Tracking the nitric oxide signaling pathway

Both nitric oxide (NO) and hydrogen sulfide (H2S) act as gaseous signaling molecules with similar physiological effects. Many of the critical questions about the interplay between these two gasotransmitters hinge on their ...

Coated zinc sulfide nanoparticles are catalytically active

Ideally, a pigment should be resistant to corrosion under light irradiation—especially to UV radiation. It should also retain its white color in the long term. Today, the industry has already achieved all this with zinc ...

Eco-friendly nanoparticles for artificial photosynthesis

Researchers at the University of Zurich have developed a type of nanoparticle by adding zinc sulfide to the surface of indium-based quantum dots. These quantum dots produce clean hydrogen fuel from water and sunlight—a ...

Team demonstrates large-scale technique to produce quantum dots

A method to produce significant amounts of semiconducting nanoparticles for light-emitting displays, sensors, solar panels and biomedical applications has gained momentum with a demonstration by researchers at the Department ...

Nanocage surfaces get 'makeover' in room temperature

Kyoto University researchers have discovered a way of replacing surface ions of copper oxide nanocrystals at ambient conditions—a feat that will make nanocage production considerably simpler.
