'Cloning' could make structurally pure nanotubes for nanoelectronics
Researchers from the University of Southern California and NIST 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.

Paper-and-scissors technique rocks the nano world
Sometimes simplicity is best. Northwestern University researchers have discovered an easy way to make nanofluidic devices: using paper and scissors. And they can cut a device into any shape and size, adding to the method's versatility. Nanofluidic devices are attractive because their thin channels can transport ions -- and with them a higher than normal electric current -- making them promising for use in batteries and new systems for water purification, harvesting energy and DNA sorting.

Nanometer-scale diamond tips improve nano-manufacturing
One of the most promising innovations of nanotechnology has been the ability to perform rapid nanofabrication using nanometer-scale tips. The fabrication speed can be dramatically increased by using heat. High speed and high temperature have been known to degrade the tip... until now. Researchers have created a new type of nano-tip for thermal processing, which is made entirely out of diamond.

New freeform standards to support scanning CMMs
The National Physical Laboratory, the UK's National Measurement Institute, has developed a new range of three dimensional standards for verifying freeform coordinate measurement machines. The standard allows the verification of portable and fixed non-contact coordinate measuring systems such as those employing laser scanning and fringe projection technologies, as well as those employing tactile sensors. It also helps evaluate the surface measurement capabilities of new scanning measurement technologies.

UT Arlington physics team demonstrates new power generation technique
University of Texas at Arlington and Louisiana Tech University researchers created a hybrid nanomaterial that can be used to convert light and thermal energy into electrical current. The team built a prototype thermoelectric generator they hope can eventually produce milliwatts for use in devices such as self-powering sensors, low-power electronic devices and implantable biomedical micro-devices, they said. UT Arlington's Wei Chen has also coupled gold nanoparticles with copper sulfide nanoparticles for potential use in cancer therapy.

Detection, analysis of 'cell dust' may allow diagnosis, monitoring of brain cancer
A novel miniature diagnostic platform using nuclear magnetic resonance technology is capable of detecting minuscule cell particles known as microvesicles in a drop of blood. Microvesicles shed by cancer cells are even more numerous than those released by normal cells, so detecting them could prove a simple means for diagnosing cancer.

Canada and Europe fund intelligent senior homes
Technology may soon be helping seniors to live longer, healthier lives. A trio of researchers, including Simon Fraser University's Andrew Sixsmith, is working to develop intelligent, interactive sensors to be embedded in seniors' homes and used to support independent living. Sixsmith and his colleagues in Toronto and Sweden are receiving $730,000 through a joint federal and European health research-funding program to develop ambient assistive living technologies.

Ben-Gurion University develops side-illuminated ultra-efficient solar cell designs
The new cell architecture developed at the David Ben-Gurion National Solar Research Center at BGU can exceed an ultra-efficient 40 percent conversion efficiency with intensities equal to 10,000 suns." Our new designs for concentrator photovoltaic cells comprise multiple tiers of semiconductor materials that are totally independent, and overcome numerous challenges in compiling the elements of even the most efficient solar cells," BGU Prof Gordon says.

Nanocrystals and nickel catalyst substantially improve light-based hydrogen production
Hydrogen is an attractive fuel source because it can easily be converted into electric energy and gives off no greenhouse emissions. A group of chemists at the University of Rochester is adding to its appeal by increasing the output and lowering the cost of current light-driven hydrogen-production systems.

New study reveals challenge facing designers of future computer chips
To build the computer chips of the future, designers will need to understand how an electrical charge behaves when confined to metal wires a few atom-widths in diameter. Now, physicists at McGill University, in collaboration with researchers at General Motors R&D, have shown that electrical current may be drastically reduced when wires from two dissimilar metals meet.

Researchers create laser the size of a virus particle
The miniaturization of the laser -- a key, workhorse instrument -- is critical to ultra-fast data processing and ultra-dense information storage. Now a Northwestern University research team has found a way to manufacture single laser devices that are the size of a virus particle and that operate at room temperature. These plasmonic nanolasers could be readily integrated into silicon-based photonic devices, all-optical circuits and nanoscale biosensors.
