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 ...
Molybdenum and hydroxybenzene complexes in concentrated sulphuric acid
(Elsevier, 1976)
It is already known [1--5] that Ti, W, V, Mo and some other metals form
coloured complexes with 1,4-benzenediol in concentrated sulphuric acid. We
have also found that hydroxybenzene has similar properties. Papers found ...
Electrochemical oxidation of formic acid at noble metals: Catalytic effects of foreign metal monolayers
(Elsevier, 1977)
The catalytic effects of a submonolayer of lead on noble metals have been shown and discussed in terms of a previously published model. A theoretical analysis of these effects is presented. It was demonstrated that foreign ...
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 ...
Investigation of the anodic processes on platinum in perchlorate and chlorate solutions by linear sweep voltammetry using the rotating double-ring electrodes
(Elsevier, 1976)
There have been several attempts to elucidate events occurring on platinum immersed into pure perchloric acid solutions, when submitted to high anodic polarisation. The polarisation curve was shown to exhibit two levels, ...
Structural change in the zeolite inclusion complex through high temperature treatment. Denitrated zeolite
(Elsevier, 1976)
In the sodium nitrate melt, sodium zeolite, NaA, forms the
inclusion complex NaA.NaNO3[1,2] which contains sodium
nitrate molecules in the central a cage. Our earlier
investigations [3] of inclusion complexes have shown ...
The dissolution of iron under cathodic polarization
(Pergamon Press, 1979)
It has been shown that the dissolution rate for iron at cathodic potential is higher than expected on the grounds of the Wagner-Traud mixed potential theory. This observation cannot be explained by a parallel chemical ...
Powdered sample analysis in a double plasma arc source in a graphite tube
(Elsevier, 1977)
A double plasma d.c. arc burning in a horizontal graphite tube in a magnetic field was developed as a light source for spectrochemical purposes. It was demonstrated experimentally that a prolongation of the residence time ...
Pulsating potential electrolysis in the deposition of copper
(Elsevier, 1973)
A very low impedance circuit was constructed in order to provide a pulsating cathodic potential for a copper electrode immersed in a copper sulphate solution of the type used in copper refining. The increase in surface ...
Electric conductivity and viscosity of 1,4-benzenediol and hydroxybenzene solutions in concentrated sulphuric acid
(Elsevier, 1974)
Many authors have dealt with the formation of the complexes of 1,4-benzenediol and some metals in concentrated sulphuric acid. However, no data can be found in the literature either on the reaction of 1,4-benzenediol with ...
