UCLA-led research team develops world's most powerful nanoscale microwave oscillators
A team of UCLA researchers has developed the world's most powerful nanoscale microwave oscillators. The new electron spin-based oscillators came out of research at UCLA Engineering, focuses on spin-transfer torque magnetoresistive random access memory or STT-RAM, which has great potential over other types of memory currently in use for both speed and power efficiency. The new oscillators could lead to mobile communication devices that are less expensive to manufacture and deliver a much better signal quality.

Nano-sandwich technique slims down solar cells, improves efficiency
Researchers from North Carolina State University have found a way to create much slimmer thin-film solar cells without sacrificing the cells' ability to absorb solar energy. Making the cells thinner should significantly decrease manufacturing costs for the technology.

Faster, cheaper gas and liquid separation using custom designed and built mesoscopic structures
In what may prove to be a significant boon for industry, separating mixtures of liquids or gasses has just become considerably easier. Using a new process they describe as "reverse fossilization," scientists at Kyoto University's WPI Institute for Integrated Cell-Material Sciences have succeeded in creating custom designed porous substances capable of low cost, high efficiency separation.

Discovery of material with amazing properties
Normally a material can be either magnetically or electrically polarized, but not both. Now researchers at the Niels Bohr Institute at the University of Copenhagen have studied a material that is simultaneously magnetically and electrically polarizable. This opens up new possibilities, for example, for sensors in technology of the future. The results have been published in the scientific journal, Nature Materials.

Graphene Research: Trapping light in a carbon net
Graphene, an ordered monolayer of carbon, is the thinnest substance known, and yet has extraordinary mechanical strength. A new study shows that its two-dimensional network of atoms can even trap light.

Penn researchers' study of phase change materials could lead to better computer memory
Memory devices for computers require a large collection of components that can switch between two states, which represent the ones and zeros of binary language. Engineers hope to make next-generation chips with materials that distinguish between these states by physically rearranging their atoms into different phases. Researchers at the University of Pennsylvania have now provided new insight into how this phase change happens, which could help engineers make memory storage devices faster and more efficient.

Researchers tune the strain in graphene drumheads to create quantum dots
Researchers have shown that they can tune the strain in graphene suspended like drumheads over microscopic holes in a substrate of silicon oxide using the tip of an advanced scanning probe microscope and a conducting plate below the substrate. Tuning the strain enabled the group to create areas in the graphene where electrons behaved as though they were confined to quantum dots.

Scientists gain understanding of self-cleaning gecko foot hair
Wall-climbing robots, bioadhesives or other sticky substances can benefit greatly from a recent discovery about the self-cleaning and reuse abilities of a gecko's foot hair by a University of Akron graduate student-researcher and his partners. Their work was published in the June 13 edition of Interface, the journal of the Royal Society. The sticky yet clean attribute of this discovery is the gecko toe pad and its ability to repeatedly attach and detach to a surface.

Graphene? From any lab!
Considered by many as the most promising material of the future, graphene still remains an expensive and hard-to-fabricate substance. Researchers from the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw, and the Interdisciplinary Research Institute in Lille developed a low cost method for manufacturing multilayered graphene sheets. The new method does not require any specialized equipment and can be implemented in any laboratory.

Taming light with graphene
Spanish research groups achieve first ever visualizations of light guided with nanometric precision on graphene. This visualization proves what theoretical physicists have long predicted; That it is possible to trap and manipulate light in a highly efficient way, using graphene as a novel platform for optical information processing and sensing. Synergies between IQFR-CSIC, ICFO and nanoGUNE give rise to these noteworthy results reported in Nature this week in a back-to-back.

Nano-pesticides: Solution or threat for a cleaner and greener agriculture?
Research is urgently needed to evaluate the risks and benefits of nano-pesticides to human and environmental health. Melanie Kah and Thilo Hofmann from the Department of Environmental Geosciences of the University of Vienna recently performed an extensive analysis of this emerging field of research. The results were published June 6th in the internationally recognized journal Critical Reviews in Environmental Science and Technology. The study presents the current scientific state of art on nano-pesticides and identifies direction priorities for future research.

In nanotube growth, errors are not an option
At the right temperature, with the right catalyst, there's no reason a perfect single-walled carbon nanotube 50,000 times thinner than a human hair can't be grown a meter long. That calculation is one result of a study by collaborators at Rice, Hong Kong Polytechnic and Tsinghua universities who explored the self-healing mechanism that could make such extraordinary growth possible.

Study improves understanding of surface molecules in controlling size of gold nanoparticles
North Carolina State University researchers have shown that the "bulkiness" of molecules commonly used in the creation of gold nanoparticles actually dictates the size of the nanoparticles – with larger so-called ligands resulting in smaller nanoparticles. The research team also found that each type of ligand produces nanoparticles in a particular array of discrete sizes.
