Electrocatalysis by foreign metal monolayers: Oxidation of formic acid on platinum
(Elsevier, 1975)
It was demonstrated that some foreign metal monolayers formed by underpotential deposition have pronounced catalytic effects on the oxidation of formic acid on platinum. The explanation of these effects was sought within ...
Quercetagetin 6,7,3',4'-tetramethyl ether: a new flavonol from Artemisia annua
(Elsevier, 1975)
Plant: Artemisia annua L. Source: South of Belgrade. A CHCl, extract of the whole plant yielded after chromatography a new polar flavonol, yellow crystals, mp 171-172 degrees, M+ m/e 374, C19H18O8. characterized by UV/VIS, ...
An analysis of elementary processes of water desorption from zeolites of type aPart. I. Zeolites with monovalent counterions: undefined
(Elsevier, 1976)
Complex DSC curves of water desorption from LiA, NaA and KA zeolites were resolved into the most probable elementary curves. The activation energies and transition temperatures of corresponding elementary processes were ...
Hydrogen evolution on gold electrode in the presence of lead adatoms
(Pergamon Press Ltd., 1979)
Investigation of occluded and nonoccluded synthetic zeolites. Base-catalyzed demethylation of tetramethylthionine-methylene blue on a denitrated zeolite
(Elsevier, 1972)
The adsorption of methylene blue from aqueous and non-aqueous media onto the zeolite NaA, the occluded zeolite NaANaNO3 and the denitrated zeolite NaANa2O has been investigated. Adsorption isotherms have a standard form ...
A novel procedure for the aromatization of ring a in 19-nortestosterone
(Elsevier, 1977)
A convenient, 40% overall yield synthesis of 2,3,17β-triacetoxy-1,3,5(10)-estratriene is described, which involves epoxidation of 19-nortestosterone and subsequent acetylation, lead tetra-acetate acetoxylation of the ...
