Optical characterization of the CdZn(S1-xSex) 2 thin films deposited by spray pyrolysis method
(2006)
CdZn(S1-xSex)2 thin films have been deposited onto glass substrates by the spray pyrolysis method at a 275°C substrate temperature. The average optical transmittance of all the films was over 65% in the wavelength range ...
Optical characterization of the CdZn(S1-xSex)(2) thin films deposited by spray pyrolysis method
(Technical University Wroclaw, 2006)
CdZn(S1-xSex)(2) thin films have been deposited onto glass substrates by the spray pyrolysis method at a 275 degrees C substrate temperature. The average optical transmittance of all the films was over 65% in the wavelength ...
The determination of the thickness and optical constants of the ZnO crystalline thin film by using envelope method
(Natl Inst Optoelectronics, 2006)
ZnO crystalline thin film has been deposited onto glass substrates by the spray pyrolysis method. The crystallographic structure of the film and the size of the crystallites in the film were studied by X-ray diffraction. ...
Structural and optical properties of ZnO films prepared by spray pyrolysis technique
(2006)
ZnO filmleri püskürtme tekniği ile farklı taban sıcaklıklarında elde edilmiş ve elde edilen bu filmlerin yapısal ve optiksel özellikleri incelenmiştir. X-ışını kırınım desenleri, filmlerin hekzagonal ve polikristal yapıda ...
Plane symmetric solutions of gravitational field equations in five dimensions
(2006)
We present the effective field equations obtained from a generalized gravity action with Euler-Poincaré term and a cosmological constant in a D dimensional bulk space-time. A class of plane-symmetric solutions that describe ...

Spectroscopic determination of acid dissociation constants of some pyridyl Shiff bases
(American Chemical Society, 2006)
The acid dissociation constants (pK(a)) of eight biologically active pyridyl Shiff bases were determined using a UV-vis spectroscopic technique at 25 +/- 0.1 degrees C. The first acidity constants (pK(a1)) of the ...
Validated capillary electrophoresis study for the determination of cetirizine in pharmaceutical forms
(Taylor & Francis Inc, 2006)
A capillary electrophoretic method for the determination of cetirizine is described in this study. The method was developed by using a running buffer consisting of 10 mM of 10% methanol with pH 8.5, employing a fused silica ...
Kinetics, isotherm and thermodynamic studies of adsorption of Acid Blue 193 from aqueous solutions onto natural sepiolite
(Elsevier Science BV, 2006)
In the present study, natural sepiolite was used as an adsorbent for the investigation of the adsorption kinetics, isotherms and thermodynamic parameters of an acid dye (Acid Blue 193, AB 193) from aqueous solution at ...
Inverted oscillator
(IOP Publishing LTD, 2006)
The inverted harmonic oscillator problem is investigated quantum mechanically. The exact wavefunction for the confined inverted oscillator is obtained and it is shown that the associated energy eigenvalues are discrete, ...
