Thermodynamics of polynuclear aromatic molecules I. Heat capacities and enthalpies of fusion of pyrene, fluoranthene, and triphenylene
(Elsevier, 1971-01)
The heat capacities of three crystalline condensed-ring aromatic substances were studied from 5 to 350 K by adiabatic cryogenic calorimetry and into the liquid phase with the intermediate-range adiabatic calorimeter. The ...
Quantitative determination of reducing sugars, oligosaccharides, and glycoproteins with [3H]borohydride
(Elsevier, 1973-09)
A very simple and direct radioactive isotope method has been described for the quantitative determination of reducing sugars. The method can be adapted to give any degree of sensitivity desired. The procedure is of general ...
Thermodynamics of Fe(II)Fe(III) oxide systems I. Hydrothermal Fe3O4
(Elsevier, 1976-06)
The heat capacity of a hydrothermally-prepared polycrystalline sample of Fe3O4 was measured from 53 to 350 K, primarily to study the thermophysics of the Verwey transitions. Although the bifurcation of the transition was ...
A shift from phospholipid to triglyceride synthesis when cell division is inhibited by trans-fatty acids
(Elsevier, 1976-10)
The yeast mutant Saccharomyces cerevisiae (KD 46) requires added unsaturated fatty acid for growth. When cell growth was inhibited by the presence of trans-acids there was a marked inhibition of oleate esterification into ...
Thermodynamics of the monohydrogen difluorides IV. The low-temperature heat capacity of NH4HF2
(Elsevier, 1976-01)
Adiabatic calorimetric results on NH4HF2 show its heat capacity to be of a simple sigmate shape from 5 to 300 K. Values of Cp(T), So(T) - So(0), {Ho(T) - Ho(0)}/T, and -{Go(T) - Ho(0)}/T at 298.15 K are 25.50, 27.61, 14.23, ...
Heat capacities of alpha-iron(II) molybdate and iron(II) molybdate-II from 5 to 350 K
(Elsevier, 1975-08)
Heat capacities of iron(II) molybdate-II (a metastable high-pressure phase) and of two samples of alpha-iron(II) molybdate were measured over the temperature range 5 to 350 K by means of adiabatic calorimetry. Rounding of ...
Affinity binding of the cartilage proteoglycan protein-keratan sulfate core to immobilized hyaluronic acid
(Elsevier, 1978-10-01)
The protein-keratan sulfate core of bovine nasal cartilage proteoglycan was purified by affinity chromatography on a column of immobilized hyaluronic acid. The hyaluronic acid was immobilized by reaction with a hydrazido-alkyl ...
