Using tiny radiation pressure forces - generated each time light is reflected off a surface - University of Oregon physicists converted an optical field, or signal, from one color to another. Aided by a "dark mode", the conversion occurs through the coupling between light and a mechanical oscillator, without interruption by thermal mechanical vibrations.

To detect the toxicity of engineered nanomaterials, such as carbon nanotubes, on living cells, researchers have developed a "nanocanary", the modern-day, high-tech equivalent of the canary in a coal mine that warned miners of dangerous buildups of toxic gases in the mine shaft.

A novel push coating technique that uses an original silicone rubber stamp having a trilayer structure has been developed. The technique enables highly efficient use of materials, improvement in thin-film crystallinity, and high resolution patterning. The findings should considerably accelerate the research and development of flexible electronic devices.

Researchers from the University of Southern California and the National Institute of Standards and Technology have demonstrated a technique for growing virtually pure samples of single-wall carbon nanotubes with identical structures, a process they liken to "cloning" the nanotubes. If it can be suitably scaled up, their approach could solve an important materials problem in nanoelectronics: producing carbon nanotubes of a specific structure to order.

One of the key challenges has been the reliability of the nanometer-scale tips, especially with performing nano-writing on hard, semiconductor surfaces. Now, researchers at the University of Illinois, University of Pennsylvania, and Advanced Diamond Technologies Inc., have created a new type of nano-tip for thermal processing, which is made entirely out of diamond.
