Rise time of silicon p-i-n photodiodes
(Elsevier, 1983)
Exact analytical expressions are derived for the short circuit photodiode currents excited by light pulses, under the assumption that the drift carrier velocity linearly depends on the electric field in the depletion layer. ...
Underpotential deposition of metals in the presence of surfactants: Deposition of thallium and lead on an Ag (100) electrode in the presence of sodium dodecyl sulphate
(Elsevier, 1985)
In this work sodium dodecyl sulphate (SDS) was used to modify the surface of an Ag (100) single crystal electrode. Both the underpotentlal deposition (UPD) and overpotential deposition (OPD) of thallium and lead were studied ...
Sesquiterpene lactones from Inula helenium
(Pergamon Press, 1989)
The isolation of 11(13)-dehydrocriolin [a germacranolide also known as 11(13)-dehydroivaxillin], 2α-hydroxyalantolactone, 4α,5α-epoxy-10α,14-H-inuviscolide (the major component) and carabrone from the aerial parts of Inula ...
Fundamental aspects of pulsating current metal electrodeposition IX: The prevention of spongy deposit formation on inert substrates
(Elsevier, 1984)
It is shown that spongy deposits are obtained under d.c. conditions and that compact deposits are obtained in pulsating current (PC) deposition with high pause-to-pulse ratios at the same average current density and ...
Carbon monoxide oxidation on mixed spinels CuxCo3-xO4 (0 ≫ × ≫ 1) in the presence of sulphur compounds
(Elsevier, 1985)
The influence of the copper content in CuxCo3-xO4 (0 ≫ × ≫ 1) mixed oxides on carbon monoxide oxidation in the presence of SO2 was investigated. The average oxidation rate was found to increase very slowly with increasing ...
A novel pimara-8(9),15-diene from lycopus europaeus
(Pergamon Press, 1985)
Identification of a novel trioxygenated Δ8(9),15_ pimaric acid methyl ester from plant species Lycopus europaeus by means of two-dimensional 1H NMR spectroscopy (COSY and NOESY) is reported. © 1985.
Optical and electrochemical study of underpotential deposition of bismuth on gold electrode
(Elsevier, 1980)
The underpotential deposition of Bi on Au has been investigated by specular reflectance spectroscopy and linear sweep voltammetry. The spectral dependance of ΔR/R caused by Bi adatoms has been determined and compared with ...
Novel trioxygenated caryophyllenes from Inula Spiraefolia
(Pergamon Press, 1982)
The identification of two novel isomeric trioxygenated caryophyllenes from the plant species Inula Spiraefolia is reported. © 1982.
Combined lyotropic and thermotropic phase transitions of deoxycholic acid
(Elsevier, 1980)
Phase transitions of deoxycholic acid have been examined by studying systems which form a clathrate during crystallization. It has been shown that, depending upon the type of solvent molecule present, the deoxycholic acid ...
Oxygen reduction on the Au (311) electrode surface in alkaline electrolyte
(Elsevier, 1988)
Oxygen reduction was studied for the first time using a single crystal electrode in a rotating disc-ring arrangement. The Au (311) surface shows a complex behaviour, with a very high activity in certain potential regions. ...
