(Elsevier Science BV, 2009)In this study, the infrared spectrum of N-(2-oxo-2H-chromen-3-yl)acetamide (3-acetamidocoumarin; 3AC) isolated in solid argon, at 10 K, was obtained and assigned. In consonance with the relative energies of the three ... -
Influence of dopant concentration on the optical properties of ZnO: In films by sol-gel method
(Elsevier Science Sa, 2009)Undoped and in doped ZnO films have been deposited by sol-gel spin coating method. The effect of indium, incorporation on structural and optical properties of ZnO films has been investigated. X-ray diffraction patterns of ... -
Investigation of carbon produced by methane pulsed discharge
(Wiley-V C H Verlag GMBH, 2007)Pulsed discharges of methane gas at atmospheric pressure were generated using high voltage power supply (20 kV-25 kHz) to produce the carbon. The pulsed discharge of methane gas was generated between two sharp wolfram ... -
The investigation of dielectric properties of pyrophyllite
(Trans Tech Publications LTD, 2004)Pyrophyllite, a clay mineral, is hydrous aluminum silicate which has a chemical formula of Al2Si4O10(OH)(2). Such properties of high dielectric constant (permittivity) and low electrical conductivity make it useful for ... -
