In this paper, the fabrication and results of zinc oxide (ZnO) thin-film CO gas sensor are discussed. The thin film c-axis oriented ZnO is deposited on Si/SiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> substrate at room temperature using RF magnetron sputtering technique. annealed different temperatures starting from 200 °C to 400 °C. crystalline structural properties analyzed by X-ray diffraction technique preferred orientation...
The photophysical properties of a hemicyanine dye, 4-[4-(dimethylamino)styryl]-1-docosylpyridinium bromide (DASPC22), have been studied in homogeneous media pure solvents and mixed using UV–vis absorption fluorescence spectroscopies. These were explored to study the binding interactions between DASPC22 nanotubes β-cyclodextrin (β-CD) absorption, steady-state anisotropy, time-correlated single-photon-counting (TCSPC) measurements dye. molecules form H-aggregates water. β-CD forms simple...
Thermal analysis of an <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">L</i> -band 60-kW (continuous-wave) double-ring strapped magnetron for optimizing the design a cathode support structure and cooling system is presented. This consists oxygen-free copper anode with ten built-in channels directly heated tungsten cathode. The operating temperature greater than 2000°C; therefore, proper thermal essential reliable operation. heat convection...
A millimetre wave antenna array, mounted on a space vehicle re-entering the Earth's atmosphere, encounters high density plasma around it. At power, field heats electrons nonuniformly. The electron temperature, Te, follows pattern, being maximum along direction of principal (z-axis) and falling off rapidly across ambipolar diffusion under pressure gradient force creates refractive index profile with z-axis, leading to self-convergence enhancement in effective gain antenna.
A practical pillbox window design was performed using impedance matching approach for use in THz vacuum electron devices. The fabricated W-band miniature assembly showed broad frequency band ~ 8 GHz VWSR less than 1.22.
To save the environment it is primarily required to electricity.Since, generation of electricity add pollutants environment.The developed desert cooler which described in this paper uses naturally blowing air provide cooling effect.It allows enter inside from four sides while outgoing only through a passage bottom.Thus blown circulated room cooler, requires no blow as conventional coolers.The describes methods designing and manufacturing cooler.A test setup presented was prepared...
Metal assisted chemical etched Si nanostructures have been transferred on flexible sheets (adhesive tape) followed by deposition of Au/Ag nanoparticles to make SERS active platform. It shows significant enhancement Raman signal glucose in the vicinity metal due its coupling with surface plasmon nanostructures. detection is extremely difficult because weak cross section and poor adsorption NPs. Fabricated platform was utilized detect without any label at low concentration 10 micro molar (μM)....
Cr-Mo creep resistant steels are used specially for power tubines and pipings due to their long term properties at elevated temperatures pressures. Welding is commonly required join the different structural components made of this steel. Therefore weld joints should also possess temperatures, which depend on correct choice filler material, preheat treatment, post heat treatment welding technique used. Possible failures remedies have been discussed. Various processes these reviewed.
