The effect of fluid flow on graphene

The application of graphene in a liquid environment has so far received little attention. Fong Yew Leong from the A*STAR Institute of High Performance Computing has now shed some light on the effects of fluid dynamics on graphene in such applications through a combination of molecular dynamics simulations and scaling arguments.

Nature may be making silver nanoparticles on its own

Nanoparticles of silver are being found increasingly in the environment - and in environmental science laboratories. Because they have a variety of useful properties, especially as antibacterial and antifungal agents, silver nanoparticles increasingly are being used in a wide variety of industrial and consumer products. This, in turn, has raised concerns about what happens to them once released into the environment. Now a new research paper adds an additional wrinkle: Nature may be making silver nanoparticles on its own.

European Food Safety Authority publishes nanotechnology guidance for food and feed assessment

The European Food Safety Authority (EFSA) has today published a guidance document for the risk assessment of engineered nanomaterial applications in food and feed. The guidance is the first of its kind to give practical guidance for addressing potential risks arising from applications of nanoscience and nanotechnologies in the food and feed chain.

Doppler effect found even at molecular level - 169 years after its discovery

Scientists have experimentally shown a different version of the Doppler effect at a very small level - the rotation of an individual molecule. Prior to this such an effect had been theorized, but it took a complex experiment with a synchrotron to prove it's for real.

Consultation: Green Paper on a Common Strategic Framework for future EU research and innovation funding

On 9th February 2011, the European Commission presented a Green Paper which proposes major changes to EU research and innovation funding to make participation easier, increase scientific and economic impact and provide better value for money. The Commission is seeking the views of all interested individuals and organisations on these proposed changes and on the specific questions set out in the Green Paper.

New technique improves artificial photosynthesis

This discovery will make it possible to improve photoelectrochemical cells. In the same way that plants use photosynthesis to transform sunlight into energy, these cells use sunlight to drive chemical reactions that ultimately produce hydrogen from water.

CO2 makes life difficult for algae

The acidification of the world's oceans could have major consequences for the marine environment. New research shows that coccoliths, which are an important part of the marine environment, dissolve when seawater acidifies.

Pyrite nanoparticles from deep-sea hydrothermal vents rich source of iron

Similar to humans, the bacteria and tiny plants living in the ocean need iron for energy and growth. But their situation is quite different than ours - for one, they can't exactly turn to natural iron sources like leafy greens or red meat for a pick-me-up. So where does their iron come from? New research points to a source on the seafloor: nanoparticles of pyrite, or fool's gold, from hydrothermal vents at the bottom of the ocean.

CEA-Leti and 5 partners collaborating on self-powered cardiac pacemaker

Leti and five partners are developing a self-powered cardiac pacemaker eight times smaller than current models. This energy self-sufficient device will harvest mechanical energy from the movements of the heart, potentially eliminating the need for battery replacement through post-op surgery and lowering healthcare costs.
