Aug 18, 2005 · Researchers produce strong, transparent carbon nanotube sheets. ... and untold trillions of these invisible strings must be assembled to make useful macroscopic articles that can exploit the ... (SHM) technique to detect, locate and quantify damage that occurs at one or more locations in large polymer composite structures (LPCSs) made of electrically non-conductive fibers and carbon nanotube networks. Our technique exploits the piezoresistive effect of multiwalled carbon nanotubes (MWCNTs) in epoxy resin. A detector for detecting infrared photons is disclosed. It comprises an anode, a cathode including a plurality of nanotubes formed from carbon and means for electrically connecting the nanotubes, and bias circuitry for applying an electric field between the anode and the cathode such that when infrared photons are absorbed by the nanotubes, photoelectrons are created.

Jun 11, 2014 · Researchers at Sandia National Laboratories, along with collaborators from Rice University and the Tokyo Institute of Technology, are developing new terahertz detectors based on carbon nanotubes ... App slate iphone.plCarbon Monoxide Fact Sheet Carbon monoxide (CO) is a poisonous gas that is created when common fuels such as natural gas, oil, wood or coal burn incompletely. This odorless, colorless, tasteless gas is often called the “silent killer” because it is virtually undetectable without the use of detection technology like a CO alarm. voltages can be easily obtained by connecting six 22.5V carbon– zinc batteries in series, suggesting that portable nanotube sensors based on the above idea could be made and utilized. Ionization sensors such as photo-ionization detectors (PID), flame-ionization detectors (FID) or electron-capture detectors Oct 24, 2011 · Researchers at UT Dallas recently demonstrated that transparent carbon nanotube sheets, which can have the density of air and the specific strength of steel, can be used to make objects invisible. In the experiment, the researchers heated the sheets electrically, which transferred the heat to the surrounding area (a petri dish of water). As you can see from the photographs, this caused light to bend away from the carbon nanotube sheet, effectively cloaking anything behind it with invisibility. See additional applications in: Optical properties of carbon nanotubes. Carbon nanotube photoluminescence (fluorescence) can be used to observe semiconducting single-walled carbon nanotube species. Photoluminescence maps, made by acquiring the emission and scanning the excitation energy, can facilitate sample characterization.

RICHARDSON, Texas (Aug. 18, 2005) – University of Texas at Dallas (UTD) nanotechnologists and an Australian colleague have produced transparent carbon nanotube sheets that are stronger than the same-weight steel sheets and have demonstrated applicability for organic light-emitting displays, low-noise electronic sensors, artificial muscles ... Dec 01, 2011 · A carbon nanotube coating developed at the University of Michigan acts as a "magic black cloth" that conceals an object's three-dimensional geometry and makes it look like a flat black sheet. The 70-micron coating, or carbon nanotube carpet, is about half the thickness of a sheet of paper.

2. Carbon nanotubes detectors. As skectched in figure 1, a possible layout for a CNTs-based prototype detector is that obtained by starting from a suitable substrate (silicon, sapphire or others) whose surface is covered with electrodes. Those electrodes are usually a few microns interdigitated in order to take high the ratio in between the ... conformance with this Material Safety Data Sheet, or in combination with any other product or process, is the responsibility of the user.

Our current sensor development results have proved that the carbon nanotube sensors can offer very high sensitivity for NO 2 , ammonia, methane, acetone, benzene and toluene detection, with detection limits in the lower ppm to ppb level and response time in seconds to minutes. Each sensor draws the power in micro-watts to milli-watts. Aug 19, 2005 · Individual carbon nanotubes are like minute bits of string, and many trillions of these invisible strings must be assembled to make useful macroscopic articles. We demonstrated such assembly at rates above 7 meters per minute by cooperatively rotating carbon nanotubes in vertically oriented nanotube ...
