The effect of the plasma composition on characteristics of the d.c. arc - V The influence of iodine vapour on the radial temperature distribution of the arc burning in the atmosphere of nitrogen and argon
(Elsevier, 1971)
Considering the solutions of the Elenbaas-Heller energy balance equation it is possible to indicate how the chemical reactions among the components of added substances influence the radial temperature distribution in the ...
Analysis of the organic matter of oil shales by nuclear magnetic resonance
(Pergamon Press, 1978)
13C NMR spectroscopy was applied in the investigation of the structure of the organic matter in oil shales. By using Proton Enhanced Nuclear Induction Spectroscopy, a fair resolution of aliphatic and aromatic carbon signals ...
Study of the reactions of hexanitrocobaltates(III) with amino acids. VII. Geometrical isomerism and absolute configuration of dinitrobis(aminoacidato)cobaltate(III) ions
(Elsevier, 1971)
Dinitrobis(aminoacidato)cobaltate(III) salts with L-α-aminobutyric acid, aminoisobutyric acid, L-valine, L-norvaline, L-leucine, L-norleucine, and L-isoleucine were prepared and resolved into optical isomers. We report ...
The effect of a localized deformation upon the common-emitter transistor current gain
(Elsevier, 1971)
Starting from the theory of the influence of pressure upon the semiconductor band diagram, and the Kroemer's proof of existence of different forces Fn and Fp acting upon the electrons and holes, a system of equations is ...
A new type of sesqiterpene lactone isolated from artemisia annua L. arteannuin B
(Elsevier, 1973)
The structure of a new sesquiterpene lactone, arteannuin B, isolated from Artemisia annua L. is reported.
Refractive index increments of di‐n‐alkylitaconate polymers and copolymers
(Wiley, 1970)
Refractive index increments of 11 poly(di‐n‐alkylitaconate) polymers were determined systematically in seven organic solvents, expected to be suitable for light scattering and other solution property measurements. Of 13 ...
Electron ground state in the semiconductor inversion layer and low frequency MIS capacitance
(Elsevier, 1976)
By varying the total energy and electrostatic energy functionals which represent an approximate self-consistent solution of Schrödinger's and Poisson's equation, the ground state of electrons is determined in a semiconductor ...
Reflectance study of cation adsorption on oxide layers of gold and platinum electrodes
(Elsevier Sequoia S.A., Lausanne, 1979)
The critical overpotential for zinc dendrite formation
(Kluwer Academic Publishers, 1979)
The critical overpotential for zinc dendrite growth is determined as 173 mV by the method described by Popov et al. [1]. It was shown that this procedure can be applied successfully to metal deposition processes when there ...
