Researchers discover important mechanism behind nanoparticle reactivity

An international team of researchers has used pioneering electron microscopy techniques to discover an important mechanism behind the reaction of metallic nanoparticles with the environment. Crucially, the research shows that oxidation of metals - the process that describes, for example, how iron reacts with oxygen, in the presence of water, to form rust - proceeds much more rapidly in nanoparticles than at the macroscopic scale.

NanoSafety Cluster launches its first newsletter

The NanoSafety Cluster is an EC initiative to maximise the synergies between the past, ongoing and future FP7 nanosafety projects. Each of these projects addresses key aspects of nanosafety, including toxicology, ecotoxicology, exposure assessment, risk assessment, standardisation, and mechanisms of interaction.

New approach produces cleanest graphene yet, with previously unrealized performance

Columbia Engineering researchers have experimentally demonstrated for the first time that it is possible to electrically contact an atomically thin two-dimensional material only along its one-dimensional edge, rather than contacting it from the top, which has been the conventional approach. With this new contact architecture, they have developed a new assembly technique for layered materials that prevents contamination at the interfaces, and, using graphene as the model 2D material, show that these two methods in combination result in the cleanest graphene yet realized.

Micromotors mix for more effective oxidative degradation of chemical weapons

Rapidly and efficiently converting chemical weapons into nontoxic products in remote areas is one of the most difficult tasks in the disposal of weapons of mass destruction. A team from the University of California, San Diego has now described how self-propelled micromotors can accelerate the oxidative neutralization of nerve agents by intensively mixing the remediation solution.
