摘要: A hydrogen detector with a porous layer of alumina. Pores with average pore diameters in the range of from about 10 to about 200 nanometers (nms) and average pore depths in the range of from about 10 to about 1000 nms have Pd nanoparticles in the pores forming a film. Electrodes on the Pd film measure changes in electrical resistance of the Pd film in the presence of hydrogen. Pd may be in the form of nanotubes. The alumina is anodized for various times to form the nanowalls or pores and vary the pore depths.

摘要: Single-walled carbon nanotubes (SWNTs) are decorated with metal nanoparticles to form high-performance flexible hydrogen sensors. The special process to form the high-performance flexible hydrogen sensors can combine a dry transfer printing technique and modification of SWNTs with palladium (Pd) nanoparticles to provide high-performance hydrogen sensors with excellent mechanical flexibility on plastic substrates. Two approaches can be used to decorate the SWNTs. One is physical deposition, such as electron beam evaporation (EBE) and the other is electrochemical deposition which can selectively grow palladium nanoparticles on the surface of the SWNTs, resulting in significantly decreasing the use of palladium. Preferably, the Pd nanoparticles are deposed on the SWNTs in a discontinuous arrangement so that the Pd nanoparticles are spaced away from each other to form individual discontinuous Pd nanoparticles rather a continuous Pd film. Advantageously, the SWNTs are arranged with substantial semiconducting pathways. Desirably, the high-performance flexible hydrogen sensors have an excellent response and recovery time, provide superior sensitivity for detecting hydrogen, and are bendable to conform to the contours of other structures.

摘要: An in situ polymer microstructure formation method. The monomer mixture is polymerized in a solvent/precipitant through exposure to ionizing radiation in the absence any chemical mediators. If an exposure mask is employed to block out certain regions of the radiation cross section, then a patterned microstructure is formed. The polymerization mechanism is based on the so-called free-radical retrograde-precipitation polymerization process, in which polymerization occurs while the system is phase separating above the lower critical solution temperature. This method was extended to produce a crosslinked line grid-pattern of poly (N-isopropylacrylamide), which has been known to have thermoreversible properties.

摘要: This invention provides ways to fabricate nanotubes and nanobead arrays by utilizing nanopores in anodic aluminum oxide (AAO) membranes. Nanotubes of bismuth and other low melting point metals with controlled diameters and lengths can be fabricated by sintering AAO coated with appropriate metals at temperatures above their melting points. Carbon nanotubes may also be readily formed by carbonizing a polymer on the interior walls of the nanopores in AAO membranes. Palladium nanobead arrays which can be used as ultrafast hydrogen sensors are fabricated by coating the flat surface of AAO membranes with controlled pore-wall ratios.
