X-ray diffraction methods have been used to measure long- and short-range order parameters for single crystals of the alloy Cu3Au held at elevated temperatures. It is shown that short-range order parameters may be obtained by a three-dimensional Fourier analysis of the ``scattering power'' for the diffuse background s…

Statistical Mechanics of Swelling of Network Structures

Paul J. Flory1950-01-01OpenAlex

Inaccuracies in previously published theories dealing with the swelling of network polymers in solvents are pointed out. The treatment of Flory and Rehner, based on the tetrahedral model, is overly restrictive and leads to an entropy of swelling which is too small. A more recent treatment of Kuhn, Pasternak, and Kuhn…

One-dimensional dislocations - III. Influence of the second harmonic term in the potential representation, on the properties of the model

F. C. Frank、J. H. van der Merwe1949-12-22Proceedings of the Royal Society of London A Mathematical and Physical Sciences

Abstract In the previous one-dimensional dislocation model, a single sinusoidal term was taken to represent the potential energy of the deposit as a function of its position on the substrate. In this model a more general representation of the potential, containing a second harmonic term as well, is used, and it is sho…

The kinetics of the polymerization of sarcosine carbonic anhydride

S G Waley、James M. Watson1949-12-07Proceedings of the Royal Society of London A Mathematical and Physical Sciences

Abstract The polymerization of carbonic anhydrides, a reaction important but&gt;u as a preparative method for the synthesis of polypeptides and as an example of a less familiar type of polymerization, has been studied in detail using sarcosine carbonic anhydride (I). The propagation reaction has been shown to invo…
