Aluminum nitride, an important member of the group III nitrides with the highest bandgap of about 6.2 eV, has excellent thermal conductivity, good electrical resistance, low dielectric loss, high piezoelectric response, and ideal thermal expansion, matching that of silicon. The interest in field-emission (FE) applications of AlN materials has grown because(More)
Rhodostomin (Rho) is a snake venom protein isolated from Calloselasma rhodostoma. Rho is a disintegrin that inhibits platelet aggregation by blocking the binding of fibrinogen to the integrin alpha(IIb)beta3 of platelets. Rho produced in Escherichia coli inhibited platelet aggregation with a K(I) value of 263 nM. Although functional, Rho produced in E. coli(More)
Beaklike SnO2 nanorods were synthesized by a vapor-liquid-solid approach using Au as a catalyst. The nanorods grow along the [10 1] direction and the beak is formed by switching the growth direction to [1 12] through controlling the growth conditions at the end of the synthesis. The photoluminescence (PL) spectrum of the nanorods exhibits visible light(More)
Taper- and rodlike Si nanowires (SiNWs) are synthesized successfully on Si and Si(0.8)Ge(0.2) substrates. The growth mechanisms of taper- and rodlike SiNWs are proposed to be oxide-assisted growth (OAG) and vapor-liquid-solid (VLS) growth, respectively. For taperlike SiNWs annealed at 1200 degrees C for 3 h, the emission peaks are found at 772, 478, and 413(More)
In wireless networks, network coding has been considered as an effective approach that utilizes the broadcast nature of the wireless channel to achieve energy efficiency and improve the network throughput. While network coding can be utilized in different forms of communications, including unicast, multicast and broadcast, the MAC layer transmissions used(More)
Staphylococcal enterotoxins are potent T cell mitogens. Recent studies have shown that the binding of these toxins to class II MHC molecules on accessory cells is essential for the stimulation of T cells which bear specific V beta segment of TCR. In the present study we show that i.v. administration of staphylococcal enterotoxin B (SEB) results in an(More)
With the rapid growth and construction of information, the traditional voice-based static network has been gradually changed to dynamic network. By analyzing the current equipment situation and transmission services of metropolitan area network, some short comings which exist in the current transmission network come to conclusion. On the basis of the(More)
In addition to carbon nanotubes, the production of noncarbon nanostructures has attracted much attention over the past few years. In particular, and due to their unusual geometry and promising physical properties, inorganic fullerene nanostructures have become one of the main focuses in nanoscale research since the first report of the synthesis of WS2(More)
