Abstract: Method for producing metal oxide nanoparticles. The method includes generating an aerosol of solid metallic microparticles, generating plasma with a plasma hot zone at a temperature sufficiently high to vaporize the microparticles into metal vapor, and directing the aerosol into the hot zone of the plasma. The microparticles vaporize in the hot zone into metal vapor. The metal vapor is directed away from the hot zone and into the cooler plasma afterglow where it oxidizes, cools and condenses to form solid metal oxide nanoparticles.

Abstract: The present invention provides methods for modulating cellulose, hemicellulose and lignin composition and deposition in secondary cell wall layers of plants to improve plant traits that are commercially desirable (e.g., enhanced digestibility of forage crops by animals, increased post-harvest processing of wood and crops for energy production and pulping, increase mechanical strength of plants, and others). The invention also provides methods for identifying genes encoding transcription factors that regulate the formation of secondary cell walls, polynucleotide sequences that encode key components of secondary cell walls, and transgenic plants comprising these sequences.

Abstract: The present invention relates to a method for effecting the closure of an application window in response to an event associated with its parent window. The method comprises polling an indicator associated with the parent application window and in the absence of said indicator accessing a system provided function causing the closure of the application window.

Abstract: A method for closing a child application window of a parent window. An indicator is instantiated in data loaded into the parent window, followed by performance of a loop. In each iteration of the loop: (a) if it is ascertained that the data currently loaded into the parent window includes the indicator, then pausing of a first number of seconds is followed by looping back to perform the next iteration, otherwise pausing of a second number of seconds is followed by determining whether the data currently loaded into the parent window includes the indicator; (b) if it is determined that the data currently loaded into the parent window includes the indicator, then pausing of the first number of seconds is followed by looping back to perform the next iteration, otherwise the loop is exited and the child application window is closed during a final iteration.

Abstract: In a field effect transistor having a quantum well is provided by a primary conduction channel, at least one secondary conduction channel immediately adjacent and in contact with the primary channel has an effect bandgap greater than the effective bandgap of the primary channel, and the modulus of the difference between the impact ionisation threshold IIT of the primary channel and the effective conduction band offset (the height of the step) between the primary and secondary channels being no more than 0.5 Eg (effective), or (alternatively) no more than 0.4 eV. Higher energy carriers which might otherwise cause impact ionization leading to runaway are thus diverted into the secondary channel allowing the device to run faster at increased voltages and/or to exhibit much greater resistance to runaway. The primary channel is prefereably of low bandgap material, for example InSb, InAs, InAs1-y, In1-xGaxAs.

Abstract: Graphitic structures have been prepared by exposing templates (metal, metal-coated ceramic, graphite, for example) to a gaseous mixture that includes hydrocarbons and oxygen. When the template is metal, subsequent acid treatment removes the metal to yield monoliths, hollow graphitic structures, and other products. The shapes of the coated and hollow graphitic structures mimic the shapes of the templates.

Abstract: An intramedullary nail (20) and related method for fixing a fracture in a long bone. The nail (20) comprises an elongate member (22) having a longitudinal axis (54), a proximal end section (32), a distal end section (34) and a solid central section (24) extending between the proximal and distal end sections (32, 34). The proximal and distal end sections (32, 34) respectively include proximal and distal fastener receiving areas (28, 30) of greater cross sectional dimensions than the central section (24). Each fastener receiving area (28, 30) includes at least one hole (50, 52) extending transverse to the longitudinal axis for receiving a cross fastener (110) adapted to secure to the bone on opposite sides of the elongate member (22). The proximal and distal end sections (32, 34) thereby provide rigid anchoring locations relative to the central section (24) and the central section provides flexibility to promote healing of the fracture.

Abstract: Method for producing carbon nanotubes. Carbon nanotubes were prepared using a low power, atmospheric pressure, microwave-generated plasma torch system. After generating carbon monoxide microwave plasma, a flow of carbon monoxide was directed first through a bed of metal particles/glass beads and then along the outer surface of a ceramic tube located in the plasma. As a flow of argon was introduced into the plasma through the ceramic tube, ropes of entangled carbon nanotubes, attached to the surface of the tube, were produced. Of these, longer ropes formed on the surface portion of the tube located in the center of the plasma. Transmission electron micrographs of individual nanotubes revealed that many were single-walled.

Abstract: A bipolar transistor with vertical geometry comprises a base region (1) provided with a base contact (21), emitter and collector regions (2,3) arranged to extract minority carriers from the base region, and an excluding structure for counteracting entry of minority carriers into the base region via the base contact, wherein the base region has a bandgap of greater than 0.5 eV and a doping level greater than 1017 cm?3. As shown the base includes an excluding heterojunction (4) preventing entry of carriers from the base contact (21), but alternatively the base region could comprise a “high-low” doping homojunction. The construction shows improved resistance to thermal runaway even in multi-finger transistors. It is particularly useful for high power, high frequency transistors, e.g. base on gallium indium arsenide. The collector region preferably has a heterostructure.

Abstract: A catalytic reactor system especially useful for hydrogenation, dehydrogenation, hydrocarbon isomerization, and hydrocracking was demonstrated for isomerizing 1-butene to 2-butene. The reactor system includes a noble metal-containing catalyst bed and a base-metal catalyst bed in physical contact with but substantially unmixed with the noble metal catalyst bed. The reactor includes a gas inlet for sending hydrogen to the noble metal catalyst and an inlet for sending 1-butene to the second catalyst bed. An outlet is provided for product and unreacted hydrogen and 1-butene. The reactor system is configured such that hydrogen flows through the noble metal catalyst bed first and then through the base-metal catalyst bed, while 1-butene flows through the base metal catalyst bed, with minimal backflow through noble metal bed.

Abstract: Method for producing metallic particles. The method converts metallic nanoparticles into larger, spherical metallic particles. An aerosol of solid metallic nanoparticles and a non-oxidizing plasma having a portion sufficiently hot to melt the nanoparticles are generated. The aerosol is directed into the plasma where the metallic nanoparticles melt, collide, join, and spheroidize. The molten spherical metallic particles are directed away from the plasma and enter the afterglow where they cool and solidify.
