Heat capacity of MnAs0.88P0.12 from 10 to 500 K: Thermodynamic properties and transitions
(Elsevier, 1987-10)
The heat capacity of MnAs0.88P0.12 has been measured by adiabatic shield calorimetry from 10 to 500 K. It is shown that very small energy changes are connected with two magnetic order-order transitions, indicating that ...
Thermophysics of metal alkanoates VII. Heat capacities and thermodynamic properties of potassium n-butanoate
(Elsevier, 1987-02)
The subambient heat-capacity curve of potassium n-butanoate as determined by adiabatic equilibrium calorimetry is characterized by a "bifurcated" transition whose "peaks" occur at 123.85 and 142.3 K. The corresponding (Cp, ...
Decreased pulmonary vascular responsiveness in rats raised on an essential fatty acid deficient diet
(Elsevier, 1987-02)
Leukotriene C4 is produced during hypoxic pulmonary vasoconstriction and leukotriene inhibitors preferentially inhibit the hypoxic pressor response in rats. If lipoxygenase products are important in hypoxic vasoconstriction, ...
Synthesis and rearrangements of ortho-selenonium phenoxides
(Elsevier, 1987)
A new class of selenonium zwitterions is prepared from the ortho- substitution of phenols with diphenylselenium bis(trifluoroacetate) 1. The zwitterions undergo a novel thermal rearrangement to produce diaryl ethers.
Thermodynamics of copper sulfides I. Heat capacity and thermodynamic properties of copper(I) sulfide, Cu2S, from 5 to 950 K
(Elsevier, 1987-11)
The heat capacity of Cu2S from 5 to 950 K was determined by adiabatic-shield calorimetry and the thermodynamic properties were evaluated. Transitions occur at 376 and about 710 K with [Delta]trsSm = (1.240+/-0.006)R and ...
