The fun way to manipulate atoms

With their potential to perform calculations far beyond the reach of conventional supercomputers, machines harnessing certain quantum physics phenomena are expected to change the way the world solves complex problems. They ...

Silver atom nanoclusters could become efficient biosensors

Researchers have now managed to pinpoint what happens when light is absorbed by extremely small nanoclusters of silver atoms. The results may have useful application in the development of biosensors and in imaging.

Ionization mechanisms of captive atoms struck by light matter

Light interacting with hydrogen atoms enclosed in hollow cages composed of carbon atoms - referred to as fullerene material - produces ionisation. This phenomenon, which has been the subject of intense theoretical scrutiny, ...

Optimizing atomic neighborhoods for speedier chemical reactions

Scientists have discovered that for palladium-nickel catalysts, certain surface characteristics, measured at the atomic level, sped the creation of carbon dioxide from carbon monoxide. To reveal the optimal atomic neighborhood ...

Japan upgrades Fukushima leak to highest level in two years

Japan declared a radioactive water leak at the crippled Fukushima plant a level-three "serious incident" Wednesday, its highest warning in two years, as operators scrambled to seal a tank that has seeped 300 tonnes of toxic ...

Elucidating energy shifts in optical tweezers

A small piece of paper sticks to an electrically charged plastic ruler. The principle of this simple classroom physics experiment is applied at the microscopic scale by so-called optical tweezers to get the likes of polystyrene ...

Designing materials for the future

As energy demands rise, materials scientists are increasingly interested in developing longer-lasting materials for use in the next generation of advanced nuclear and fusion reactors. However, before researchers can think ...
