Latest Carbon nanotube Stories
[ View the Video ] It's been long known that asbestos spells trouble for human cells. Scientists have seen cells stabbed with spiky, long asbestos fibers, and the image is gory: Part of the fiber is protruding from the cell, like a quivering arrow that's found its mark. But scientists had been unable to understand why cells would be interested in asbestos fibers and other materials at the nanoscale that are too long to be fully ingested. Now a group of researchers at Brown...
RED BANK, N.J., Sept. 14, 2011 /PRNewswire/ -- The U.S. Patent Office has awarded patent no. 7,999,176 B2 to Natcore Technology Inc. (TSX-V; NXT; NTCXV.PK) for a solar cell structure that uses carbon nanotubes to improve cell performance. Approved in April, this patent was issued on August 16. This patent, and the three earlier foundational patents on which it is based, cover a liquid phase deposition (LPD) process for growing inorganic films on silicon. One of these earlier patents is at...
Rice researchers power line-voltage light bulb with nanotube wire Cables made of carbon nanotubes are inching toward electrical conductivities seen in metal wires, and that may light up interest among a range of industries, according to Rice University researchers. A Rice lab made such a cable from double-walled carbon nanotubes and powered a fluorescent light bulb at standard line voltage -- a true test of the novel material's ability to stake a claim in energy systems of the...
Polyurethane reinforced with carbon nanotubes outperforms currently used materials Efforts to build larger wind turbines able to capture more energy from the air are stymied by the weight of blades. A Case Western Reserve University researcher has built a prototype blade that is substantially lighter and eight times tougher and more durable than currently used blade materials. Marcio Loos, a post-doctoral researcher in the Department of Macromolecular Science and Engineering, works with...

National experts, led by Case Western Reserve University researcher, wins federal grant CLEVELAND, Aug. 10, 2011 /PRNewswire-USNewswire/ -- A national team of experts, led by a Case Western Reserve University researcher, has received a multi-million-dollar grant to bring unrivaled qualities found in one- and two-dimensional nanomaterials into three dimensions. The scientists' goal is to produce new materials for a host of uses, ranging from high-efficiency batteries, ultracapacitors, fuel...
DNA, a molecule famous for storing the genetic blueprints for all living things, can do other things as well. In a new paper,* researchers at the National Institute of Standards and Technology (NIST) describe how tailored single strands of DNA can be used to purify the highly desired "armchair" form of carbon nanotubes. Armchair-form single wall carbon nanotubes are needed to make "quantum wires" for low-loss, long distance electricity transmission and wiring.Single-wall...
The Elsevier journal Reinforced Plastics reported that Zyvex Technologies' Piranha, a 54 ft unmanned boat built using carbon nanotube strengthened prepreg, has completed sea trials which demonstrate record fuel efficiency. Piranha is an unmanned surface vessel (USV) designed to enable a broad range of operations at sea with reduced operational costs and risks to sailors. The ground-breaking research that make such advances possible are reviewed in new and forthcoming books from Elsevier's...
Penn researchers have helped develop a nanotech device that combines carbon nanotubes with olfactory receptor proteins, the cell components in the nose that detect odors.Because olfactory receptors belong to a larger class of proteins that are involved in passing signals through the cell membrane, these devices could have applications beyond odor sensing, such as pharmaceutical research. The research was led by professor A. T. Charlie Johnson, postdoctoral fellow Brett R. Goldsmith and...
GLEN ALLEN, Va., July 25, 2011 /PRNewswire/ -- Industry analyst firm NanoMarkets has released its latest report on the transparent conductor market. In its new report the firm states that the market opportunities for the transparent conducting oxides, polymers and nanomaterials used in display, photovoltaics and other applications will exceed $6.9 billion in revenues by 2016. The report notes that while the market will continue to be dominated by Indium Tin Oxide (ITO), transparent...
