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 ...
Ion beam modification of metals: Compositional and microstructural changes
(Elsevier, 1989)
Ion implantation has become a highly developed tool for modifying the structure and properties of metals and alloys. In addition to direct implantation, a variety of other ion beam techniques such as ion beam mixing, ion ...
Application of resonance Raman spectrometry to the determination of vitamin b12
(Elsevier, 1975-05)
High levels of non-activated receptors in glucocorticoid-sensitive S49wt mouse lymphoma cells incubated with dexamethasone
(Elsevier, 1994-10)
Upon agonist binding the heteromeric glucocorticoid receptor complex under goes a conformational change (receptor activation). This event involves the dissociation of a dimer of 90 kDa heat shock proteins. Whereas receptor ...
Curing reaction and product properties of polysulfones terminated with active functional groups
(Wiley Subscription Services, Inc., A Wiley Company, 1991-11-20)
The curing processes of maleimide-terminated polyether sulfone oligomers ( M n from 1100 to 3000) and ethynyl-terminated polysulfone prepolymers ( M n from 2600 to 12000) were investigated by means of DSC. The ...
Relationship between the subunit structure of insulin receptor and its competence to bind insulin and undergo phosphorylation
(Elsevier, 1984-11-01)
Insulin receptor partially purified from human placenta by chromatography on immobilized wheat germ agglutinin was subjected to affinity cross linking to determine the relationship between the subunit structure of the ...
Expression and regulation of cytochrome P-450I genes (CYP1A1 and CYP1A2) in the rat alimentary tract
(Elsevier, 1992-12-29)
Cytochrome P-450 (P450) enzymes in the mucosa of the alimentary tract may be involved in the activation and/or inactivation of ingested xenobiotics and procarcinogens. Since the multiple P450 enzymes have overlapping ...
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 ...
