X-ray and carbon-13 nuclear magnetic resonance characterization of cyclopropane derivatives obtained by solvolysis of (E)-3α- and (E)-3β-hydroxy-5,10-seco-1(10)-cholesten-5-one tosylates
(Pergamon Press, 1979)
The stereochemistries and conformations of the cyclopropane ring containing compounds derived from (E-3α- and (E)-3β-hydroxy-5,10-seco-1(10)-cholesten-5-one tosylates have been determined by X-ray methods and the results ...

Photochemically induced oxidation of some steroidal isoxazolidines by molecular oxygen
(Royal Society of Chemistry, 1977)
U.v. irradiation of the steroidal isoxazolidines 5α,10α-imino- oxy-5(10 → 1βH)abeo-5α-cholestan-3β-olacetate (1a) and the corresponding N-methyl and N-acetyl derivatives (1b) and (1c) in various solvents in the presence ...
Catalytic effect of metal adatoms deposited at underpotential
(AIP Publishing, 1974)
Electrochemical deposition of up to a monolayer of
metal on foreign substrates at potentials positive to the
reversible one (underpotential deposition) has been
known for some time. 1,2 It appeared interesting to see
if ...
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 ...
Mass spectrometric analysis of plasma composition of a D. C. arc burning in an air atmosphere / Massenspektrometrische Analyse der Plasmazusammensetzung eines Gleichstrombogens in Luft
(Springer-Verlag, 1979)
The plasma composition of a d. c. arc burning in air was investigated by mass spectrometry. It has been found that the CO and CO2 contents result from homogenous chemical reactions and that the content of carbon is about ...
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 ...
Static characteristics of the metal-insulator-semiconductor- insulator-metal (MISIM) structure—II. Low frequency capacitance
(Elsevier, 1975)
It is shown that the reciprocal value of low frequency capacitance of a MISIM structure can be represented by a sum of reciprocal values of insulator layer and surface space charge capacitances and an “interaction” term ...
