Using carbon nanotubes (hollow tubes of carbon atoms), MIT chemical engineers have found a way to concentrate solar energy 100 times more than a regular photovoltaic cell. Such nanotubes could form antennas that capture and focus light energy, potentially allowing much smaller and more powerful solar arrays. “Instead of having your whole roof be a [...]
Simpler Way to Build Many Industrial and Household Chemicals Phosphorus, a mineral element found in rocks and bone, is a critical ingredient in fertilizers, pesticides, detergents and other industrial and household chemicals. Once phosphorus is mined from rocks, getting it into these products is hazardous and expensive, and chemists have been trying to streamline the [...]
ScienceDaily (Aug. 28, 2010) — In a step toward more efficient, smaller and higher-definition display screens, a University of Michigan professor has developed a new type of color filter made of nano-thin sheets of metal with precisely spaced gratings. The gratings, sliced into metal-dielectric-metal stacks, act as resonators. They trap and transmit light of a [...]
Clinical trials using patients’ own immune cells to target tumors have yielded promising results. However, this approach usually works only if the patients also receive large doses of drugs designed to help immune cells multiply rapidly, and those drugs have life-threatening side effects. Now a team of MIT engineers has devised a way to deliver [...]
Nanotechnology will be changing the world in ways that we can’t even imagine now. And like the paths of those earlier “big ideas,” nanotech is just beginning to scratch the surface – giving investors another chance to beat the crowd. In a report recently released by the Joint Economic Committee titled “Nanotechnology: The Future Is [...]
Tiny cancer-fighting agents are poised to play a big role in the future of chemotherapy. The breast cancer foundation Susan G. Komen for the Cure has awarded a UC Davis researcher $450,000 for the development of nanoparticles capable of effectively targeting and destroying tumor cells while leaving healthy cells unharmed. The grant, given to Dr. [...]
A new combination of nano and solar technology has made it possible for solar electric generation to be cheaper than burning coal. Nanosolar, Inc. has developed a way to produce a type of ink that absorbs solar radiation and converts into electric current. Photovoltaic (PV) sheets are produced by a machine similar to a printing [...]
On July 19, the Nano Korea Organization committee announced that ‘Nano Korea 2010 with IEEE NANO ‘ will be held from August 17 to 20 at KINTEX, Korea. The theme of its 8th event is “‘Nanotechnology for a Green World’. During the event they will redefine various issues about environment and energy in the nano-technical perspective, share of [...]
The people who run the Millennium Project of the American Council for the United Nations University (ACUNU) wanted to better understand the “Potential Environmental Pollution and Health Hazards Resulting from Possible Military Uses of Nanotechnology,” along with “Implications for Research Priorities Helpful to Prevent and/or Reduce Such Pollution and Hazards.” They put together a panel, [...]
Just Coat Your Plane With Stealth Paint Stealth planes are so expensive these days, what’s a spy to do? You can’t just fly into enemy territory because now the enemies all have those damn radar devices that will go beep boop whenever you get too close, ruining your intricately planned diamond heist. Well for the [...]
