 Applied Physics LettersNanotube defects equal better energy and storage systems Most people would like to be able to charge their cell phones and other personal electronics quickly and not too often. A recent discovery made by UC San Diego engineers could lead to carbon nanotube-based supercapacitors that could do just this. Contact: Andrea Siedsma

Angewandte ChemieUCLA researchers create 'fly paper' to capture circulating cancer cells Just as fly paper captures insects, an innovative new device with nano-sized features developed by researchers at UCLA is able to grab cancer cells in the blood that have broken off from a tumor. These cells, known as circulating tumor cells, or CTCs, can provide critical information for examining and diagnosing cancer metastasis, determining patient prognosis, and monitoring the effectiveness of therapies.

NatureSmall optical force can budge nanoscale objects With a bit of leverage, Cornell researchers have used a very tiny beam of light with as little as 1 milliwatt of power to move a silicon structure up to 12 nanometers. That's enough to completely switch the optical properties of the structure from opaque to transparent.

NatureNew study confirms exotic electric properties of graphene First, it was the soccer-ball-shaped molecules dubbed buckyballs. Then it was the cylindrically shaped nanotubes. Now, the hottest new material in physics and nanotechnology is graphene: a remarkably flat molecule made of carbon atoms arranged in hexagonal rings much like molecular chicken wire.

Proceedings of the National Academy of SciencesNJIT engineer discovers why particles disperse on liquids Even if you are not a cook, you might have wondered why a pinch of flour (or any small particles) thrown into a bowl of water will disperse in a dramatic fashion, radiating outward as if it was exploding. Pushpendra Singh, Ph.D., a mechanical engineering professor at NJIT who has studied and written about the phenomenon, has not only thought about it, but can explain why.

Nature MethodsScientists guide immune cells with light and microparticles A team led by Yale University scientists has developed a new approach to studying how immune cells chase down bacteria in our bodies. They used holographic optical tweezers to guide "artificial bacteria" -- microparticles that mimic bacteria by giving off a chemical "scent," stimulating immune cells to respond. By controlling the chemical patterns produced, they were able to study how immune cells respond to and interact with these chemical signals.

Nature PhysicsNIST demonstrates 'universal' programmable quantum processor Physicists at the National Institute of Standards and Technology have demonstrated the first "universal" programmable quantum information processor able to run any program allowed by quantum mechanics—the rules governing the submicroscopic world -- using two quantum bits (qubits) of information. The processor could be a module in a future quantum computer, which theoretically could solve some important problems that are intractable today.

Nanotech in space: Rensselaer experiment to weather the trials of orbit Novel nanomaterials developed at Rensselaer Polytechnic Institute are scheduled to blast off into orbit on Nov. 16 aboard Space Shuttle Atlantis. The project, funded by the US Air Force Multi University Research Initiative, seeks to test the performance of the new nanocomposites in orbit. The materials will be mounted to the International Space Station's outer hull and exposed to the rigors of space.

Optics ExpressInvisibility visualized: German team unveils new software for rendering cloaked objects Scientists and curiosity seekers who want to know what a partially or completely cloaked object would look like in real life can now get their wish -- virtually. A team of researchers at the Karlsruhe Institute of Technology in Germany has created a new visualization tool that can render a room containing such an object, showing the visual effects of such a cloaking mechanism and its imperfections.

Physical Review LettersIn touch with molecules The performance of modern electronics increases steadily on a fast pace thanks to the ongoing miniaturization of the utilized components. However, severe problems arise due to quantum-mechanical phenomena when conventional structures are simply made smaller and reach the nanometer scale. Therefore current research focuses on the so-called bottom-up approach: the engineering of functional structures with the smallest possible building blocks -- single atoms and molecules.

Nano LettersUnderstanding mechanical properties of silicon nanowires paves way for nanodevices Silicon nanowires are attracting attention from the electronics industry due to the drive for smaller devices, from cell phones to computers. The operation of these devices, and an array of additional applications, will depend on the mechanical properties of these nanowires. Research from North Carolina State University shows that silicon nanowires are far more resilient than their larger counterparts, a finding that paves the way for smaller, sturdier nanoelectronics, nanosensors, light-emitting diodes and other applications.

Journal of Applied PhysicsNew nanocrystalline diamond probes overcome wear Researchers at the McCormick School of Engineering and Applied Science at Northwestern University have developed, characterized, and modeled a new kind of probe used in atomic force microscopy, which images, measures, and manipulates matter at the nanoscale. Using diamond, researchers made a much more durable probe than the commercially available silicon nitride probes, which are typically used in AFM to gather information from a material, but can wear down after several uses.

Nature ChemistryEngineers image nanostructure of a solid acid catalyst and boost its catalytic activity Aberration-corrected scanning transmission electron microscopy and Raman, infrared and UV-visible spectroscopies pinpoint sub-nanometer clusters of tungsten oxide mixed with tiny amounts of zirconium as the active catalytic species in the catalyst. In lab tests, the clusters increased the activity of a poor catalyst by more than 100 times. Solid acid catalysts are more environmentally friendly than liquid catalysts, which evaporate, spill and cause corrosion. Tungstated zirconia's uses include the improvement of gasoline's octane content.
