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.

Tools of the trade: Diamonds are forever... for focusing intense x-rays

Diamonds can add more than sparkle and style to X-ray experiments at the Linac Coherent Light Source. They are giving scientists a way to focus the LCLS's powerful X-rays to a much tinier, brighter point without destroying the very device that does the focusing, according to a report from the Swiss team that created the new diamond-based technology.

The next generation of switchable glass: the micro-blinds

The National Research Council, Canada is developing an innovative technology for smart glass with possible applications in sectors such as building, aircraft, automotive and displays. The micro-blinds are actuated by electrostatic forces; they allow the dynamic control of light transmission at remarkable speed and could lead to major energy savings in buildings. The idea is based on a cost-efficient manufacturing scheme.
