Influence of carriers on the capacitance of p-n junctions with deep donors
(Elsevier BV, 1974)
Applying the definition of p-n junction capacitance , which takes into account the effect of carriers in the space-charge region, a sufficiently accurate approximate expression is derived for the low-frequency capacitance ...
Static characteristics of the metal-insulator-semiconductor- insulator-metal (MISIM) structure—II. Low frequency capacitance
(Elsevier BV, 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 ...
Reflectance study of cation adsorption on oxide layers of gold and platinum electrodes
(Elsevier Sequoia S.A., Lausanne, 1979)
Oxidation and reduction of phenols
Structure-reactivity relationship in the solvolysis of 5,10-secosteroidal 5-p-nitrobenzoates
(Pergamon Press, 1979)
The solvolysis of (Z)- and (E)-3β-acyloxy-5,10-seco-1(10)-cholesten-5β-ol p-nitrobenzoates 4 and 5 has been investigated and compared with the solvolytic reactivity of the epimeric (Z)- and (E)-5α-p-nitrobenzoates 1 and ...
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 ...
Transannular solvolysis reactions in seco-steroids containing a ten-membered ring.
(Pergamon Press, 1970)
Homoallylic interaction in steroidal cyclodecenyl systems
(Pergamon Press, 1974)
Mass spectrometric analysis of plasma composition of a D. C. arc burning in an air atmosphere / Massenspektrometrische Analyse der Plasmazusammensetzung eines Gleichstrombogens in Luft
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 ...
New approach to the aromatization of ring B in 19-norsteroids and to the synthesis of equilenin-type compounds
(Royal Society of Chemistry, 1978)
When 7α-acetoxy-3,3 : 17,17-bis(ethylenedioxy)-5,10-epoxy-5β, 10β-oestran-6-one (2), formed by lead tetra-acetate acetoxylation of the parent compound (1), is heated with alkali, it undergoes ring B aromatization to give ...
