Abstract The vigorous response of multiwalled carbon nanotubes (MWNTs) to microwave irradiation, leading the release a large amount heat, is used locally melt plastic matrix adjacent within period seconds. This results in intercalation MWNTs into polymer at room temperature without any physical damage polymer. so‐called “microwave welding” approach creates new paradigm for formation very strong MWNT–polymer bonds use adhesive, and represents significant step forward fabrication functional...
Lead zirconate titanate (Pb(1.1)(Zr(0.52)Ti(0.48))O(3)) thin films of thickness 260 nm on Pt/Ti/SiO(2)/Si substrates were densified by 2.45 GHz microwave annealing. The PZT annealed at various annealing temperatures from 400 to 700 °C for 30 min. X-ray diffraction showed that the pyrochlore phase was transformed perovskite 450 and film fully crystallized. secondary (again pyrochlore) observed in films, which above 550 °C. surface morphologies changed due phase. Higher dielectric constant...
The drastic temperature rise of multiwall carbon nanotubes (MWCNTs) in response to microwave irradiation was applied weld a MWCNT paste on polymer substrate within few seconds. It provides strong bonding between the and without thermal damage substrate. A flexible field emitter made from welded polycarbonate, showing excellent electrical conduction field-emission properties even under bending. works with turn-on voltage 0.8V∕μm due direct electron transfer. By this method, printed circuits...
Polarized Raman scattering measurement on single wurtzite c-plane (001) ZnO nanorod grown by hydrothermal method has been performed at room temperature. The polarization dependence of the intensity for phonon modes A1(TO), E1(TO), and E2high in are obtained. deviations polarization-dependent spectroscopy from prediction selection rules observed, which can be attributed to structure defects as confirmed comparison transmission electron microscopy, photoluminescence spectra well dependent...
Thick piezoelectric films are fabricated by screen printing and firing the pastes prepared with either calcined or sintered composition of Pb 0.9875 [(Zr 0.52 Ti 0.48 ) 0.975 Nb 0.025 ]O 3 . Lithium carbonate equal amount Bi 2 O added as liquid phases to promote densification. The spontaneous polarization, P s , ranges from 6 10 µC/cm remanent r is 8 coercive force lies between 1.8 4KV/mm. Bimorph structure formed fabricating film on a ceramic (PZT) sheet. PZT sheet oppositely poled for...
It has been discovered that ceramic barrier layer devices fabricated by diffusion of CuO into the grain boundaries Nb/sub 2/O/sub 5/-doped (Ba/sub 0.8/Sr/sub 0.2/) (Ti/sub 0.9/Sn/sub 0.1/)O/sub 3/ semiconducting substrates, using Li/sub 2/CO/sub 3//Bi/sub liquid phase as a carrier, possess rectifying properties. The faster motion Li/sup +/ under capillary and gravity forces its grains p-type dopant are considered to be source property. Larger size n-type substrates can sintering pressed...
