Small packages delivering huge results
University of Melbourne researchers have developed an efficient system to coat tiny objects, such as bacterial cells, with thin films that assemble themselves which could have important implications for drug delivery as well as biomedical and environmental applications.

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.

Bacteria from Salar de Uyuni in Bolivia conceal bioplastic
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.

Antifreeze, cheap materials may lead to low-cost solar energy
A process combining some comparatively cheap materials and the same antifreeze that keeps an automobile radiator from freezing in cold weather may be the key to making solar cells that cost less and avoid toxic compounds, while further expanding the use of solar energy.

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.
