New chemistry for ultra-thin gas sensors

The application of zinc oxide layers in industry is manifold and ranges from the protection of degradable goods to the detection of toxic nitrogen oxide gas. Such layers can be deposited by atomic layer deposition (ALD) which ...

New, safe zinc oxide quantum dots

Nowadays, zinc oxide nanoparticles are among the most commonly used nanomaterials. They seem to be safe for humans, but there are still no standards for their toxicity, and despite investigations, the toxicological impact ...

X-rays reveal uptake of nanoparticles by soya bean crops

Scientists have, for the first time, traced the nanoparticles taken up from the soil by crop plants and analysed the chemical states of their metallic elements. Zinc was shown to dissolve and accumulate throughout the plants, ...

New options for transparent contact electrodes

Found in flat screens, solar modules, or in new organic light-emitting diode (LED) displays, transparent electrodes have become ubiquitous. Typically, they consist of metal oxides like In2O3, SnO2, ZnO and TiO2.
