Nmr Spectroscopic Study and Dft Calculations of Vibrational Analyses, Giao Nmr Shieldings and (1)J(Ch), (1)J(Cc) Spin-Spin Coupling Constants of 1,7-Diaminoheptane
(Chem Soc Ethiopia, 2009)
Vibrational frequencies and approximate mode descriptions of 1,7-diaminoheptane (dahp) have been determined via Becke-3-Lee-Yang-Parr (B3LYP) density functional method with 6-31G(d) basis set. H-1, proton coupled and ...
Characterization and Heterojunction Application of Nanorod Structure ZnO Films Prepared by Microwave Assisted Chemical Bath Deposition Method Without Any Template
(Amer Scientific Publishers, 2016)
The ZnO films have been deposited on p-type silicon (p-Si) substrates using a microwave assisted chemical bath deposition (MW-CBD) method without any template from an aqueous alkaline bath containing zinc nitrate and ...
Structural, Optical and Electrical Properties of Erbium-Doped ZnO Thin Films Prepared by Spin Coating Method
(Amer Scientific Publishers, 2016)
In order to investigate the influence of erbium (Er) content on morphological, structural and optical properties of ZnO films, both undoped and Er doped ZnO films were prepared by sol gel method using spin coating technique. ...
Hamilton formulation for the analysis of RLC circuits
(Physics Essays Publication, 2002)
The Hamiltonian formulation well known in classical mechanics is applied to RLC circuits. The flux linkages for the inductances are assumed to be the generalized momenta (conjugate momenta), and the Hamiltonian function ...
Biquaternionic representations of angular momentum and Dirac equation
(Slovak Acad Sciences Inst Physics, 2003)
In the present article, after defining biquaternions, the general properties of biquaternion's algebra are introduced. The matrix representations of biquaternions are presented, as well. Then, the biquaternionic angular ...
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 ...
Nitrate removal from aqueous solution by hexadecyltrimethylammoniumbromide- modified clinoptilolite
(2011)
In the first stage of study, detailed characterization studies were performed on clinoptilolite-rich tuff mined from the Gördes/Manisa region (Turkey). The physical and chemical properties were determined using instrumental ...
Catalysis of autoxidation of 2,6-di-tert-butylphenol in water by metallophthalocyanine tetrasulfonates bound to polyelectrolyte supports
(Scientific Technical Research Council Turkey, 1996)
2,6-and 2,10-Ionenes and soluble poly(vinylbenzyl)trimethylammonium chloride polyelectrolytes were synthesized and used as catalyst supports for cobalt-, iron- and copper-phthalocyanine tetrasulfonates on the autoxidation ...
