Pressure-treated wood is great stuff, but the chemicals used to preserve it from decay can leach out, where they can be toxic to insects, fungi and other creatures.

Gold nanoparticles can help identify Salmonella in five minutes, which is considerably faster than the 12-24 hours required to grow a reliable culture in a lab.

Researchers in the US and Korea have imaged growing nanocrystals on the atomic scale for the first time.

Researchers in China and Australia have observed superlubricity – the dropping of friction to near zero – on length scales much larger than before.

A new way to fabricate 3D nanostructures from gallium nitride using a focused ion beam (FIB) has been developed by researchers in Moldova, Australia, Germany and France.

Researchers at Oregon State University have tapped into the extraordinary power of carbon nanotubes to increase the speed of biological sensors. This technology might one day allow a doctor to routinely perform lab tests in minutes, speeding diagnosis and treatment while reducing costs. 

Research by University of Brighton scientists on the use of silver nanoparticles to decontaminate mercury-contaminated water has been highlighted by ‘Science’.

Chemists at Brown University have created a triple-headed metallic nanoparticle that reportedly performs better and lasts longer than any other nanoparticle catalyst studied in fuel-cell reactions. The key is the addition of gold: It yields a more uniform crystal structure while removing carbon monoxide from the reaction.

A new, single-step method of fabricating microcapsules, which have potential commercial applications in industries including medicine, agriculture and diagnostics, has been developed by researchers at the University of Cambridge.
