Determination of small amounts of zirconium--I: gravimetric procedures using mandelic acid and its derivatives
(Elsevier, 1963-06)
The limiting factors have been investigated for precipitation of zirconium at the milligram level by mandelic acid, p-bromomandelic acid and m-nitromandelic acid; the latter has only been briefly studied previously. Optimum ...
Capillary penetration between dissimilar solids
(Elsevier, 1968-04)
The major purpose of this study was to develop and evaluate a mathematical model for the capillary penetration of a liquid between two dissimilar plates. Attempts have been made in the past to apply the Young-Laplace ...
Voltammetric determination of iodide and bromide at the rotating pyrolytic graphite electrode
(Elsevier, 1966)
A voltammetric procedure has been developed for the determination of iodide and bromide by oxidation at the rotating pyrolytic graphite electrode (R.P.G. electrode) in sulfate background. The method can be extended to cover ...
Metabolism of plasmalogen III. Relative reactivities of acyl and alkenyl derivatives of glycerol-3-phosphorylcholine
(Elsevier, 1965-06-01)
1. (1) The alkenyl ether derivatives of phospholipids (plasmalogens) react at slower rates than the acyl analogs in several enzyme-catalyzed reactions.2. (2) Alkenylglycerol-3-phosphorylcholine is essentially inert as a ...
Starch-gel electrophoresis of citrate-condensing enzyme from pig heart
(Elsevier, 1963)
Citrate-condensing enzyme from pig heart can exist in vitro as two distinct species which are separable by starch-gel electrophoresis. Several mild types of treatment can interconvert these enzymes and suggest that the ...
Heat capacity and vapor pressure of crystalline bis(benzene)chromium. Third-law entropy comparison and thermodynamic evidence concerning the structure of bis(benzene)chromium
(Elsevier, 1969-05)
Heat capacity measurements from 5 to 350[deg] K and vapor pressure measurements on bis(benzene)chromium together with the published frequency assignments permit a correlation between the third-law and spectroscopic entropies. ...
