Corrosion of Pure and Amalgamated Zinc in Concentrated Alkali Hydroxide Solutions
(IOP Publishing, 1974)
Corrosion of pure and amalgamated zinc in pure concentrated KOH solutions was investigated using two methods: (a) galvanostatic measurements of the kinetics of hydrogen evolution with electrodic assessment of corrosion ...
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 ...
Criteria for the determination of the stereochemistry of steroidal indolizidines
(Elsevier, 1974)
E/F-Indolizidine steroids, which represent a structural unit of Solanum alkaloids, have been synthesized and used to evaluate criteria (IR—Bohlmann bands,1a-c —hydrogenbond,2a-e NMR,3a-c mass spectra,4 kinetic studies of ...
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 ...
A new type of d.c. arc as spectrochemical light source
(Elsevier, 1974)
A new type of d.c. arc light source for spectrochemical purposes has been developed. The horizontal arc burning in a graphite tube is placed in an inhomogeneous magnetic field. The limits of detection of In and Pb have ...
Homoallylic interaction in steroidal cyclodecenyl systems
(Pergamon Press, 1974)
A new technique for measuring adsorption on non-noble metals
(Elsevier, 1974)
A new technique for measuring adsorption on non-noble metals is presented here on the basis of former experimental results and experience.
Influence of carriers on the capacitance of p-n junctions with deep donors
(Elsevier, 1974)
Applying the definition of p-n junction capacitance [1], 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 ...
