Stress - strain isotherms and thermoelastic properties of crosslinked amorphous polyoxyethylene in compression
(Elsevier, 1975-05)
Stress-strain isotherms at a number of temperatures in the range 45-85[deg]C have been determined for a compressed, amorphous polyoxyethylene network swollen with a constant amount of non-volatile diluent. The observed ...
The preparation and some reaction of F2PSPF2 and F2PC(CF3)2OPF2, and the synthesis of the bis-borane adduct of F2PSSPF2
(Elsevier, 1976)
The potentially bidentate fluorophosphine ligand F2PSPF2 can be prepared in 75% yield from the reaction of F2PBr and [(C4H9)3Sn]2S. On the basis of infrared and Raman spectra, the compound has been assigned a bent confirmation ...
Application of resonance Raman spectrometry to the determination of vitamin b12

On the extension of the model of matrix acid stimulation to different sandstones
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1976-07)
A model was developed for the acidization of various sandstone cores which successfully describes the flow and reaction in the porous media during acidization. A comparison of the experimental results of various investigators ...
Thermodynamics of the monohydrogen difluorides V. Melting thermodynamics of NH4HF2
(Elsevier, 1976-03)
The heat capacity of ammonium hydrogen difluoride was extended from 300 to 450 K by adiabatic calorimetry in order to study the melting phenomenon and provide thermodynamics into the liquid region. The corrected enthalpy ...
Thermophysical measurements on transition-metal tungstates III. Heat capacity of antiferromagnetic manganese tungstate
(Elsevier, 1976-07)
Three anomalies were found during measurements of the heat capacity of manganese tungstate from 4 to 350 K by adiabatic calorimetry; a small peak at (6.8 +/- 0.1) K, and two large sharp peaks at (12.57 +/- 0.05) K and ...
