Binary gas diffusion of methane-nitrogen through porous solids
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1977-05)
Diffusion rates of nitrogen and methane have been measured across ten porous solids at 35°C and 1 atm by a steady state flow method. The porous plugs used were cylindrical in shape, with diffusion occurring in the direction ...
Reactive intermediates in the photolysis of cyclopentadienylcobalt(I) dicarbonyl and in the reduction of cyclopentadienylcobalt(III) carbonyl diiodide
(Elsevier, 1977-02-22)
Photolysis of (C5H5)Co(CO)2 (I) in toluene or petroleum ether solution at -78[deg]C generates the unsaturated monocarbonyl species (C5H5)Co(CO), which was identified in solution by its IR spectrum. At room temperature, ...
Phosphorescence microwave photoexcitation spectrum of 1,4-dibromonaphthalene
(Elsevier, 1977-02-15)
The phosphorescence microwave photoexcitation spectrum of 1,4-dibromonaphthalene is obtained by monitoring the X-trap phosphorescence at 20164 cm-1 and AM modulating the 2942 MHz zero-field spin resonance. The comparative ...
Reaction patterns of cyclopentadienylcobalt(I) carbonyl and acetylene derivatives
(Elsevier, 1977-02-22)
Studies have been made of photochemical and thermal reaction sequences through which bisubstituted acetylenes are transformed in (C5H5)Co-carbonyl reaction systems into cyclobutadiene and cyclopentadienone complexes and ...
High-pressure liquid chromatography and field desorption mass spectrometry of heme a, Heme a dimethyl ester and acetyl heme a dimethyl ester
(Elsevier, 1977-07-21)
Field desorption mass spectroscopy was shown to be a valid technique for determining the molecular weights of hemins and hemin esters, as well as of porphyrins. The observed base peaks of ligand-free protoheme IX, protoheme ...
Formation of palmityl-[3'-32P]coenzyme a from [[gamma]-32P]ATP in mitochondrial extracts of guinea pig liver
(Elsevier, 1977-01-15)
Investigations of the incorporation of 32P into acyl-coenzyme A (CoA) in incubation mixtures containing a soluble protein preparation derived from mitochondria, [[gamma]-32P]ATP, and palmityl-CoA have led to the discovery ...
Analysis of the carbon-13 and proton NMR spectra of bovine chromaffin granules
(Elsevier, 1977-03-29)
Natural abundance carbon-13 and proton NMR spectra of bovine chromaffin granules have been obtained and analyzed using computer simulation techniques. High resolution spectra show the presence of a fluid aqueous phase ...
Thyroid control over biomembranes : Rat liver mitochondrial inner membranes
(Elsevier, 1977-06)
The effects of hypothyroidism and one injection of -thyroxine on oxidative phosphorylation and the composition of proteins and phospholipids were examined in vesicles prepared from rat liver mitochondria by digitonin ...
