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.
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 ...
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 ...
Multiphoton resonance absorption characteristics
(IOP Publishing, 1977)
It is shown that the Dyson equation gives finite values for multiphoton resonance absorption rates when an appropriate diagram summation technique is applied. A simple recurrence formula connects the n-photon absorption ...
Electrocatalysis by foreign metal monolayers. Oxidation of formic acid on palladium
(Elsevier, 1978)
Catalytic effects of foreign metal monolayers deposited at underpotentials have been found for the oxidation of formic acid on palladium electrode. Palladium is known to form no poisoning species in oxidation of HCOOH. ...
On the kinetics and mechanism of the Cd(II)/Cd(Hg) system in acid media
(Elsevier, 1977)
The kinetics and mechanism have been investigated in the Cd(II)/Cd(Hg) system in 2 M NaClO4 + 1 M HClO4, at 25 ± 0.5°C. The galvanostatic single-pulse method has been used. The value of double-layer capacity, exchange ...
Studies of the deposition of cadmium on foreign substrates
(Elsevier, 1977)
Cadmium deposition on nickel, lead, silver, gold and copper has been studied by the potential sweep and potentiostatic method with a simultaneous observation of the surface by optical microscopy. It was found that the ...
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 ...
