Direct solution analysis using an arc source incorporating two plasmas rotating in a graphite tube
(Elsevier, 1977)
As a continuation of earlier work on arc sources for the spectrochemical analysis of powdered samples, a source appropriate for multi-element analysis of trace elements in solution has been developed. The nebulized solution ...
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 ...
A simple boundary condition at semiconductor-insulating substrate interface of a TFT
(Elsevier, 1977)
Using the Wexler, Green and Miles (WGM) procedure, a criterion is given for neglecting the electric field in insulating substrate of a Thin Film Transistor in presence of surface states. It is shown that this is fulfilled ...
Cohesive energy densities of poly(di‐n‐alkyl itaconates)
(Wiley, 1977)
The solubility parameters of the first ten members of the homologous series of poly(di‐n‐alkyl itaconates) were determined from limiting viscosity numbers in various organic solvents, differing in structure, polarity and ...
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 ...
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 ...
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 ...
1H n.m.r. spectra of some bicyclic compounds: I—relative configurations of the diastereomeric endo‐α‐methyl‐5‐norbornene‐2‐methanols, the corresponding saturated analogues, and their cyclization ether products
(Wiley, 1977)
The configurational and conformational relationship at C‐2 and C‐α in the two racemic diastereomeric endo‐α‐methyl‐5‐norbornene‐2‐methanols and the corresponding saturated endo‐α‐methyl‐2‐norbornanemethanols were determined ...
