Researchers in Switzerland, Germany and The Netherlands have succeeded in imaging single skyrmion bubbles in an experiment for the first time using a technique called soft X-ray holography. The way the tiny structures move implies that they behave like particles with mass – a finding that might be important for understanding topologically related structures in […]

A new type of nanoparticle could allow patients to be imaged in six different ways with an injection of just one contrast agent, reports an international research team. If put into clinical use, the technology could give doctors the ability to combine the strong points of a number of imaging techniques, providing a clearer overall […]

Carbon nanoparticles can act as antioxidants according to new spectroscopy experiments by researchers in Houston, Texas. The hydrophilic carbon clusters studied can work as fast as most naturally occurring single-site enzymes for converting reactive oxygen species, such as superoxide, to oxygen without affecting “good” free radicals like nitric oxide. The finding will be important for […]

More than 15 years ago, Stanford University launched “Folding@Home”, a distributed computing project that enabled anyone who chose to take part to donate their computer’s idle processing power for protein-folding number crunching. The project has since led to 114 published research articles and was recently extended to harness idle processing power in smartphones via a […]

Researchers in the US and Italy say they have succeeded in making the first field-effect transistors from “silicene” – something that was thought difficult to do until now, since the material rapidly degrades in air. Silicene is a sheet of silicon just one atom thick arranged in a hexagonal lattice and is a close cousin […]

When single-walled carbon nanotubes are made, a mixture of both metallic and semiconducting nanotubes is produced. This is a problem when trying to make electronic devices from these nanomaterials because, ideally, either semiconducting or metallic tubes are needed depending on the application and not both. Now, researchers in the US have found that a polymer […]

Researchers at the University of Michigan in the US have made a new type of nanomaterial, dubbed aramid nanofibre, that is as strong as carbon nanotubes but which is much easier and cheaper to produce – from Kevlar™ threads. The material can suppress dendrite growth in the ion-transporting separators placed between the cathode and anode […]
