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.
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.
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.
Researchers at Chalmers University of Technology have built a very simple nanoantenna that directs red and blue colours in opposite directions, even though the antenna is smaller than the wavelength of light.
Stanford University's Global Climate and Energy Project is awarding $3.5 million to researchers at five universities to develop new technologies that could dramatically improve energy storage capacity on the electric grid.
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.
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.
Scientists have observed individual phase slips in aluminum nanowires and characterized the nature and temperature at which they occur. This information could help scientists remove phase slips from nano-scale systems, which could lead to more reliable nanowires and more efficient nanoelectronics.
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.
