Theory of Thermal Unimolecular Reactions in the Fall‐off Range. II. Weak Collision Rate ConstantsAbstract The master equation of thermal unimolecular reactions in the fall‐off range has been solved for a number of representative molecular systems. Weak collision broadening factors F WC (k 0 /k ∞) are derived and represented empirically. Weak col... ...

A mechanistic theory of hydrogen embrittlement of steelsAbstract Consideration of the relation between the cohesive energy and the surface free energy leads to the inference that dissolved hydrogen reduces the maximum cohesive resistive force of which the iron lattice is capable. This forms the basis of a mechanistic model for the velocity of hydrogen‐induced crack propagation in steels. The crack grows when the local te... ...

Applications of the Augmented van der Waals Theory of Fluids.: I. Pure FluidsAbstract The relation for the compressibility of hard convex bodies (Boublik, 1975) is combined with the power series in (u/k T ) and (V°/V ) (Alder et al., 1972) to obtain the most general and accurate equation of state of fluids. 24 universal constants of the series were fitted to the internal energy and ...

Theory of Thermal Unimolecular Reactions in the Fall‐off Range. I. Strong Collision Rate ConstantsAbstract (k 0 /k ∞)‐reduced strong collision fall‐off curves of thermal unimolecular reactions are analyzed. They are represented by the Lindemann‐Hinshelwood expression multiplied by strong collision broadening factors F SC . The factors ...

Magnetic Susceptibility and Equilibrium Diagram of PdHnAbstract The limits n αmax and n βmin of the two‐phase region of PdHn can only roughly be estimated from the shape of the equilibrium isotherms pH2 (n ). Other methods applied so far do not yield more accura... ...

Layer‐Type Transition Metal Dichalcogenides — a New Class of Electrodes for Electrochemical Solar CellsAbstract The problem of the rapid anodical photoelectrochemical desintegration of visible‐light‐sensitive semiconductor electrodes (e.g. CdS, GaAs) in presently investigated continuously operating electrochemical solar cells is tackled by two improvements: a) The use of covalent layer‐type transition metal dichalcogenides as electrode material, in wh... ...

Umorientierungszeiten, Sprungzeiten und Quadrupolkopplungskonstanten in einigen organischen Flüssigkeiten aus kernmagnetischen RelaxationszeitmessungenAbstract Die kernmagnetische Spin‐Gitter‐Relaxationszeit T 1 von Protonen und Deuteronen wurde impulstechnisch bei zehn organischen Flüssigkeiten, die in der normalen protonenhaltigen Form bzw. deuteriert vorlagen, bestimmt. Durch Messungen der Protonenrelaxationszeit in Mischungen aus protonenhaltigen und deuterierten ... ...

A Comparative Study of the Viscosity Coefficients of Some Nematic Liquid CrystalssAbstract The viscosity coefficients η1 , η2 , η3 and η12 of 4‐n‐pentyl‐4'‐cyanobiphenyl, 4‐n‐octyl‐4'‐cyanobiphenyl, 4‐methoxy‐4'‐n‐butylazoxybenzene and an aromatic ester mixture were determined in the nematic phase region. Except for 4‐n‐octyl‐4'‐cyanobiphenyl, the viscosity coeffici... ...

Spectroelectrochemical Study of Mediators I. Bipyridylium Salts and Their Electron Transfer Rates to Cytochrome cAbstract In many potentiometric titrations of biological electron transfer components, mediators are often employed to act as electron transfer mediators between the components and the potentiometric electrode. Certain mediators have been employed recently as electrogenerated titrants of components in coulometric... ...
