Using Nanotubes in Computer Chips
MIT September 12th, 2009 A new technique for growing carbon nanotubes should be easier to integrate with existing semiconductor manufacturing processes

Solar cell made from single carbon nanotube
rdmag.com September 12th, 2009 Using a carbon nanotube instead of traditional silicon, Cornell researchers have created the basic elements of a solar cell that hopefully will lead to much more efficient ways of converting light to electricity than now used in calculators and on rooftops. The researchers fabricated, tested and measured a simple solar cell called a photodiode, formed from an individual carbon nanotube. Reported online Sept. 11 in the journal Science, the researchers—led by Paul McEuen, the Goldwin Smith Professor of Physics, and Jiwoong Park, assistant professor of chemistry and chemical biology—describe how their device converts light to electricity in an extremely efficient process that multiplies the amount of electrical current that flows. This process could prove important for next-generation high efficiency solar cells, the researchers say. "We are not only looking at a new material, but we actually put it into an application—a true solar cell device," said first author Nathan Gabor, a graduate student in McEuen's lab.

UWSP picked for research center
wausaudailyherald.com September 13th, 2009 The University of Wisconsin-Stevens Point has been chosen as one of seven UW campuses that will house new research centers designed to create relationships with small companies to stimulate business and develop new technologies. UWSP chemistry professor Michael Zach has been one of the national leaders in nanotechnology research and has a position at Argonne as well. Some of his recent work has focused on a technique that would allow almost anyone to create nanowires using simple, bench-top technology instead of million-dollar laboratories. That process would allow small startups to compete economically with giant corporations, and could expand the uses of nanowires.

Nanotechnology shows potential for oil and gas operations (OE 2009)
offshore-mag.com September 14th, 2009 There are many possibilities for nanoparticle technology applications in oil and gas operations, but the realities lag the possibilities, Sergio Kapusta said at Offshore Europe 2009 today. Kapusta, chief scientist and manager of Energy Innovation and Technology for Shell Global Solutions International, identified a number of operations that could benefit from nanotechnology in time. One of those areas is in reservoir management. At present, industry can acquire limited information from short distances outside the wellbore in hydrocarbon reservoirs. Drawing from medical applications, Kapusta said it could become possible to send nano "robots" into a reservoir and interrogate those robots to gather information about the horizon and also to deliver chemicals into the reservoir.

Power station ash for new cut price fillers
europeanplasticsnews.com September 14th, 2009 A new reprocessing technology that extracts high performance fillers from the waste ash produced by coal-fired power stations could slash the cost of manufacturing performance polymer compounds, according to process developer RockTron. The UK-based company - set up with £35m (€39.8m) of backing from a group of private and commercial investors, with a significant stake held by UK-based power station operator Scottish and Southern Energy - is running its first commercial scale reprocessing unit alongside the Fiddlers Ferry power station at Widnes in the north-west of England. This first installation has the capacity to handle 200 tonnes an hour of pulverised fuel ash (PFA) waste, from which it extracts a range of products including cenospheres (alumino-silicate hollow glass spheres), solid alumino-silicate microspheres, carbon and magnetite.

Nano material could boost new microchips
isa.org September 14th, 2009 "The new material we are predicting—graphone—makes graphene magnetic simply by controlling the amount of hydrogen coverage—basically, how much hydrogen is put on grapheme," said Puru Jena, Ph.D., distinguished professor in the Virginia Commonwealth University Department of Physics. "It avoids previous difficulties associated with the synthesis of magnetic grapheme." "One of the important impacts of this research is that semi-hydrogenation provides us a very unique way to tailor magnetism. The resulting ferromagnetic graphone sheet will have unprecedented possibilities for the applications of graphene-based materials," said Qiang Sun, Ph.D., research associate professor with the VCU team.

Scientists Build Nanostructures out of Single DNA Strands

Located at BioCity in Nottingham, the company has launched a reactor that allows the highly controlled production of nanoparticles in water for the first time ever and is now expanding at pace through feasibility studies and new contracts. Judges were particularly impressed at the firm's ability to take complex technology and transform it into a commercial opportunity capable of creating jobs and also developing new revenue streams for the University.

Under Observation - Restless Atoms Cause Materials to Age
Austrian Science Fund September 14th, 2009 Atoms have the habit of jumping through solids - a practice that physicists have recently been able to follow for the first time using a brand new method. This scientific advance was made possible thanks to the utilisation of cutting-edge X-ray sources, known as electron synchrotrons. The detailed findings of the project, backed by the Austrian Science Fund FWF, were recently published in the prestigious journal NATURE MATERIALS. The work unlocks new potential for the study of material ageing processes at the atomic level.

When Nano May Not Be Nano

Hybrid nano material targets antibiotic resistant bacteria
rsc.org September 14th, 2009 German researchers have developed a hybrid, light activated nanomaterial that can target, label and kill harmful antibiotic resistant bacteria such as Escherichia coli. The zeolite-based material may one day play a major role in both diagnosing and treating infectious diseases and possibly cancer, suggests the team. So-called 'photodynamic therapy' is a well-established technique in which a light source is used to trigger the action of a light-sensitive drug, and is already used to treat cancer and macular degeneration. However, scientists have been eager to develop cheaper therapeutic approaches with more functions. One such approach would be to develop a single nanomaterial that can carry out three important therapeutic jobs in one; that is, selectively target pathogens, label them (for diagnostic purposes) and then kill them.

Using magnetism to turn drugs on and off
Children’s Hospital Boston September 18th, 2009 Many medical conditions, such as chronic pain, cancer and diabetes, require medications that cannot be taken orally, but must be dosed intermittently, on an as-needed basis, over a long period of time. A few delivery techniques have been developed, using an implanted heat source, an implanted electronic chip or other stimuli as an "on-off" switch to release the drugs into the body. But thus far, none of these methods can reliably do all that's needed: repeatedly turn dosing on and off, deliver consistent doses and adjust doses according to the patient's need.

Colored Solar Panels Don’t Need Direct Sunlight
inhabitat.com September 18th, 2009 With normal solar cells, you need direct sunlight for them to generate power, and if the panels are at all shaded the efficiency drops significantly. A new type of solar cell, being developed in Jerusalem, is making huge waves because it can generate power from diffuse light using a specialized colored panel. They look a bit like colored plexi-glass but are actually panes made with fluorescent dyes and nanoparticle metals, and could possibly eclipse traditional solar panels in terms of price.
