New nanoscale imaging method finds application in plasmonics
Researchers from NIST and the University of Maryland have shown how to make nanoscale measurements of critical properties of plasmonic nanomaterials, the specially engineered nanostructures that modify the interaction of light and matter for a variety of applications including sensors, cloaking (invisibility), photovoltaics and therapeutics.

Artificial organelles transform free radicals into water and oxygen
Researchers at the University of Basel have successfully developed artificial organelles that are able to support the reduction of toxic oxygen compounds. This opens up new ways in the development of novel drugs that can influence pathological states directly inside the cell. The results have been published in the Journal "Nano Letters".

Air Force support for a new generation of lithium-ion batteries
Four years ago, a Rice University research team demonstrated that they could chemically unzip cylindrical shaped carbon nanotubes into soluble graphene nanoribbons (GNR) without compromising the electronic properties of the graphitic structure. A recent paper by the team, published in IEEE Spectrum and partially funded by AFOSR, showed that GNR can significantly increase the storage capacity of lithium ion by combining graphene nanoribbons with tin oxide.

NIST shows how to make a compact frequency comb in minutes
Laser frequency combs -- high-precision tools for measuring different colors of light in an ever-growing range of applications -- are not only getting smaller but also much easier to make. NIST physicists can now make the core of a miniature frequency comb in one minute. Conventional microfabrication techniques, by contrast, may require hours, days or even weeks.

Putting more science into the art of making nanocrystals
Andrew Greytak, a chemist in the College of Arts and Sciences at the University of South Carolina, is leading a research team that's making the process of synthesizing quantum dots much more systematic. His group just published a paper in Chemistry of Materials detailing an effective new method for purifying CdSe nanocrystals with well-defined surface properties.

Jagged graphene edges can slice into cell membranes
Researchers from Brown University have shown how tiny graphene sheets can be big trouble for cells. Sharp corners and jagged edges on the sheets puncture cell membranes, allowing the sheet to enter the cell and disrupt function. The new understanding of how graphene interacts with cells could lead to safer production of this important nanomaterial.

In Bolivia, in the largest continuous salt desert in the world, researchers from the Polytechnic University of Catalonia have found a bacterium that stores large amounts of PHB, a prized polymer. This biodegradable plastic is used by the food and pharmaceutical industries, for example to produce nanospheres to transport antibiotics.

Heat radiation of small objects: Beyond Planck's equations
In 1900, Max Planck came up with his famous equation, describing heat radiation of stars or glowing metal - but it is not applicable for very small objects. Physicists in Vienna have studied the heat radiation of ultra thin glass fibers. Their findings can be explained by the more general theory of fluctuational electrodynamics. Understanding heat radiation of small objects is important for nanotechnology, and also for climate predictions.

Eavesdropping on lithium ions
It's a jungle down there at batteries' atomic level, with ions whacking into electrodes, eventually causing the battery to fail. Now, a Michigan Technological University scientist has developed a device that lets researchers spy on the actions of lithium ions inside a nanobattery -- and use that data to develop better, longer-lasting batteries to power everything from electric cars to cell phones.

Molecular chains hypersensitive to magnetic fields
Researchers have for the first time created perfect one-dimensional molecular wires of which the electrical conductivity can almost entirely be suppressed by a weak magnetic field at room temperature. The underlying mechanism is possibly closely related to the biological compass used by some migratory birds. This spectacular discovery may lead to radically new magnetic field sensors, for smartphones for example. The leading scientific journal Science publishes the research results on 4 July.

Tiny tweezers allow precision control of enzymes
Hao Yan and his colleagues at Arizona State University's Biodesign Institute describe a pair of tweezers shrunk down to an astonishingly tiny scale. The group demonstrated that the nanotweezers, fabricated by means of the base-pairing properties of DNA, could be used to keep biological molecules spatially separated or to bring them together as chemical reactants, depending on the open or closed state of the tweezers.
