Researchers seek way to make solar cells ultra-thin, flexible
Researchers at The University of Texas at Dallas are developing nanotechnology that could lead to a new platform for solar cells, one that could drive the development of lighter, flexible and more versatile solar-powered technology than is currently available. The National Science Foundation recently awarded a $390,000 grant to the researchers to further explore their research on the feasibility of ultrathin-film photovoltaic devices, which convert light from the sun into electric power.

Researchers create 'nanoflowers' for energy storage, solar cells
Researchers from North Carolina State University have created flower-like structures out of germanium sulfide (GeS) – a semiconductor material – that have extremely thin petals with an enormous surface area. The GeS flower holds promise for next-generation energy storage devices and solar cells.

Improving nanometer-scale manufacturing with infrared spectroscopy
While there have been significant breakthroughs in nano-manufacturing, there has been much less progress on measurement technologies that can provide information about nanostructures made from multiple integrated materials. Researchers at the University of Illinois Urbana-Champaign and Anasys Instruments Inc. now report new diagnostic tools that can support cutting-edge nano-manufacturing. Using atomic force microscope based infrared spectroscopy to characterize polymer nanostructures and systems of integrated polymer nanostructures, researchers were able to chemically analyze polymer lines as small as 100 nm

The best of both catalytic worlds
Berkeley Lab researchers have combined the best properties of heterogeneous and homogeneous catalysts by encapsulating metallic nanoclusters within the branched molecular arms of dendrimers. The results are heterogenized homogeneous nanocatalysts that are sustainable and feature high reactivity and selectivity.

Glowing DNA invention points towards high speed disease detection
Many diseases, including cancers, leave genetic clues in the body just as criminals leave DNA at a crime scene. But tools to detect the DNA-like sickness clues known as miRNAs, tend to be slow and expensive. Now Chemistry researcher Tom Vosch and plant molecular biologist Seong Wook Yang, University of Copenhagen, have invented a DNA sensor, coupling genetic material to a luminous molecule which goes dark only in the presence of a specific target.

Catalytic converters like it hot
Catalytic converters work poorly if they have not yet warmed up. Tiny metal particles in a catalytic converter require a minimum temperature to function efficiently. At the Vienna University of Technology, thanks to a new measuring method, it has now become possible to examine many different types of these particles at the same time. Reliable information regarding what it is exactly that the efficiency of catalytic converters depends on has thus been obtained for the first time.

Origin of ultra-fast manipulation of domain walls discovered
An international team of researchers has found at the free electron laser FLASH a surprising effect that leads in ferromagnetic materials to a spatially varying magnetization manipulation on an ultrafast timescale. This effect could be the key to further miniaturization and performance increase of magnetic data storage devices.

Building 3-D structures from a 2-D template
In modern telecommunications, light carries digital information over kilometers within seconds. Adapted optical materials con-trol the light signals. In the AFM journal, researchers from Ber-lin, Louvain, and from Karlsruhe Institute of Technology present a method to produce photonic crystals. Their optical properties are adjusted by structures of micrometer size. The method is rapid, cheap, and simple and partly uses the self-organization principle (DOI: 10.1002/adfm.201201138).

University of Minnesota engineers invent new device that could increase Internet download speeds
A team of scientists and engineers at the University of Minnesota has invented a unique microscale optical device that could greatly increase the speed of downloading information online and reduce the cost of Internet transmission. The device uses the force generated by light to flop a mechanical switch of light on and off at a very high speed. This development could lead to advances in computation and signal processing using light instead of electrical current.
