Researchers develop ideal single-photon source

With the help of a semiconductor quantum dot, physicists at the University of Basel have developed a new type of light source that emits single photons. For the first time, the researchers have managed to create a stream ...

Scientists 'squeeze' light one particle at a time

A team of scientists has successfully measured particles of light being "squeezed", in an experiment that had been written off in physics textbooks as impossible to observe.

Copper clusters capture and convert carbon dioxide to make fuel

Capture and convert—this is the motto of carbon dioxide reduction, a process that stops the greenhouse gas before it escapes from chimneys and power plants into the atmosphere and instead turns it into a useful product.

Closer look at microorganism provides insight on carbon cycling

Some of the world's tiniest organisms may have a large impact on climate change. Researchers from the U.S. Department of Energy's Argonne National Laboratory and the University of Tennessee found that microorganisms called ...

New lenses grown layer-by-layer increase X-ray power

When you're working with the brightest x-ray light source in the world, it's crucial that you make use of as many of the photons produced as possible. That's why physicists Hanfei Yan and Nathalie Bouet at the National Synchrotron ...

X-ray imaging reveals secrets in battery materials

In a new study, researchers explain why one particular cathode material works well at high voltages, while most other cathodes do not. The insights, published in the 19 June issue of the journal Science, could help battery ...

Nanosilver and the future of antibiotics

Precious metals like silver and gold have biomedical properties that have been used for centuries, but how do these materials effectively combat the likes of cancer and bacteria without contaminating the patient and the environment?
