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 ...
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 ...
