Publication bubble threatens China's scientific advance

Chinese researchers published more than 1.2 million papers from 2006 to 2010 - second only to the United States. But these impressive numbers mask an uncomfortable fact: most of these papers are of low quality or have little impact. Citation per article (CPA) measures the quality and impact of papers. China's CPA is 1.47, the lowest figure among the top 20 publishing countries.

Hints of universal behavior seen in exotic 3-atom states

A novel type of inter-particle binding predicted in 1970 and observed for the first time in 2006, is forming the basis for an intriguing kind of ultracold quantum chemistry. Chilled to nano-kelvin temperatures, cesium atoms---three at a time---come together to form a bound state hundreds or even thousands of times larger than individual atoms.

Edible carbon dioxide sponge made with all-natural nanostructures

A year ago Northwestern University chemists published their recipe for a new class of nanostructures made of sugar, salt and alcohol. Now, the same team has discovered the edible compounds can efficiently detect, capture and store carbon dioxide. And the compounds themselves are carbon-neutral.

Self-healing membranes - nature shows the way

Empa researchers have borrowed this trick from nature and developed a polymer foam surface coating with a closed cell construction which not only reduces the pressure loss after the membrane is damaged but also makes the inflatable structure more resistant and giving it a longer operational life.

Controlling silicon evaporation improves graphene

Scientists from the Georgia Institute of Technology have for the first time provided details of their "confinement controlled sublimation" technique for growing high-quality layers of epitaxial graphene on silicon carbide wafers. The technique relies on controlling the vapor pressure of gas-phase silicon in the high-temperature furnace used for fabricating the material.

Research highlights advances in nano-optics - nanoplasmonics and metamaterials

Light-matter interaction at the nanometer scale has turned into a very fast-growing field of research known as nano-optics. To highlight breakthroughs in the specific areas of nano-optics known as nanoplasmonics and metamaterials, the editors of the Optical Society's open-access journal Optical Materials Express have published a special Focus Issue on Nanoplasmonics and Metamaterials.
