Self-assembled superlattices create molecular machines with 'hinges' and 'gears'
A combined computational and experimental study of self-assembled silver-based structures known as superlattices has revealed an unusual and unexpected behavior: arrays of gear-like molecular-scale machines that rotate in unison when pressure is applied to them.

£800,000 grant to create the computers of the future
Dr. Patmore was the recipient of one of the small number of University Research Fellowships bestowed annually by the Royal Society, which was founded in the 1660s. The fellowships -- for which there is intense competition -- run for several years, during which the Society provides the bulk of the recipient's salary and meets the cost of consumable items needed for research.

To bridge LEDs' green gap, scientists think small... really small
Nanostructures half the breadth of a DNA strand could improve the efficiency of light emitting diodes, especially in the 'green gap,' simulations at the US Department of Energy's National Energy Research Scientific Computing Center have shown. Nanostructure LEDs made from indium nitride could lead to more natural-looking white lighting while avoiding some of the efficiency loss today's LEDs experience at high power.

Energy breakthrough uses sun to create solar energy materials
Researchers have discovered a way to tap the sun not only as a source of power, but also to directly produce the solar energy materials that make this possible. This breakthrough could make the sun almost a 'one-stop shop' that produces both the materials for solar devices and the eternal energy to power them.

Fighting cancer with lasers and nanoballoons that pop
Researchers are developing a better delivery method for cancer drugs by encapsulating the drugs in nanoballoons -- which are tiny modified liposomes that, upon being struck by a red laser, pop open and deliver concentrated doses of medicine.

A pocket-size ultrasonic nebulizer employing a novel nozzle improves inhalers
Inhalation is an increasingly important route for non-invasive drug delivery for both systemic and local applications. Control of particle size and output plays a critical role in the efficient and effective delivery of oft en expensive medications to the lung. Drugs designed to treat pulmonary diseases or for systemic absorption through the alveolar capillary bed require optimum particle sizes (1 to 6 μm) for effective delivery.

Structural insights into the inner workings of a viral nanomachine
Researchers at the Virginia Tech Carilion Research Institute are using new nanoscale im-aging approaches to shed light on the dynamic activities of rotaviruses, important pathogens that cause life-threatening diarrhea in young children. Once a rotavirus enters a host cell, it sheds its outermost protein layer, leaving behind a double-layered particle (DLP). These DLPs are the form of the virus that produces messenger RNA molecules, which are critical for launching the infection.

Making the most of carbon nanotube-liquid crystal combos
Dispersions of carbon nanotubes with liquid crystals have attracted much interest because they pave the way for creating new materials with added functionalities. Now, a study published in EPJ E by Marina Yakemseva and colleagues focuses on the influence of temperature and nanotube concentration on the physical properties of such combined materials.

A breakthrough in creating invisibility cloaks, stealth technology
Scientists have managed to create artificial nanostructures that can 'bend light,' called metamaterials. But the challenge has been making enough of the material to turn invisibility cloaks into a practical reality. The work of Debashis Chanda at the University of Central Florida, however, may have just cracked that barrier.

Fabricating nanostructures with silk could make clean rooms green rooms
Tufts University engineers have demonstrated that it is possible to generate nanostructures from silk in an environmentally friendly process that uses water as a developing agent and standard fabrication techniques. This approach provides a green alternative to the toxic materials commonly used in nanofabrication while delivering fabrication quality comparable to conventional synthetic polymers. Nanofabrication is at the heart of manufacture of semi-conductors and other electronic and photonic devices.
