Photosynthetic membrane development in Rhodopseudomonas spheroides: Incorporation of bacteriochlorophyll and development of energy transfer and photochemical activity
(Elsevier, 1969-10-21)
1. 1. Bleached cells of Rhodopseudomonas spheroides, obtained by aerobic growth in the light, rapidly synthesize bacteriochlororphyll and carotenoids when transferred to 4% oxygen in the dark. Fluorescence excitation spectra ...
Vibrational analysis of chain folding in polyethylene crystals
(John Wiley & Sons, Inc., 1968-05)
The vibration frequencies of a polyethylene crystal lattice have been computed for various structures in which a fully deuterated chain is mixed with a normal chain. Intermolecular potential functions previously developed ...
Radiochemical separation of indium by amalgam-exchange
(Elsevier, 1962-01)
The radiochemical separation of indium by an amalgam-exchange technique has been critically evaluated for the aqueous hydrogen bromide system. The efficiency and contamination of the separation has been studied using tracers ...
Semipermeable ion-exchange membranes as a preconcentration matrix for trace analysis by electrochemical and neutron-activation techniques
(Elsevier, 1969-01)
Ion-exchange membranes were used in conjunction with neutron-activation analysis and anodic stripping voltammetry for the determination of certain trace metal ions. The various parameters which govern the applicability, ...
Isotopic tracer studies on the biosynthesis of deoxyribose in the rat
(Elsevier, 1963)
The biosynthesis of deoxyribose, in vivo, was studied with NaH14CO3 as a tracer, in normal adult, starved adult, normal newborn, "thiamine-deficient" adult and "tumor bearing" rats and in Yoshida ascites-tumor cells. ...
A force field for secondary chlorides
(Elsevier, 1967-08)
A force field has been derived for monochloro- and 2,4-dichloro-hydrocarbons. The Snyder-Schachtschneider force field for hydrocarbons was used as a starting point, the constants associated with the secondary chlorine being ...
Tetrahedral approximation in normal coordinate calculations of high polymers
(Elsevier, 1965-06)
The catalytic polarographic current of a metal complex : II. The nickel(II)-o-phenylenediamine system
(Elsevier, 1964-04)
The catalytic current observed as a pre-wave when Ni(II) is reduced polarographically in the presence of small quantities of o-phenylenediamine is studied as a function of Ni(II) ion and o-phenylenediamine concentration. ...
