Polymer Physics: Organization of Macromolecules in the Solid State

Polymer Crystallization as the Self-Organization of Chain Macromolecules

M D simulation is used to investigate ther self-organization exhibited by a chain of atoms with strong interaction between nearest neighbours and weak interaction between more distant atoms. It is shown that the supermolecular structure is formed in several steps: at first, an initially straight chain becomes zigzag-shaped, then the zigzag ribbon folds, producing regions of crystalline and amor...

Iii. Solid State Physics

The well known phenomenological theory of F. and H. London leads to rather severe restrictions for the electronic wave functions which might possibly account for the phenomenon of superconductivity. Yet all attempts to construct such wave functions according to the principle of quantum mechanics have been so far unsuccessful. This failure seems to stem from the use of one-electron functions for...

Iii. Solid State Physics

The application of symmetry considerations to the theory of superconductivity has been considered further. The problem consists of extending the methods recently advanced (1) so as to include the interaction of the electrons with the lattice vibrations. (See Quarterly Progress Report, April 15, 1951.) It now appears that the difficulties which have been blocking progress are not of a formal mat...

Solid State Physics

By definition, solid state is that particular aggregation form of matter characterized by strong interaction forces between constituent particles (atoms, ions, or molecules). As a result, a solid state material has an independent geometric form (in contrast to liquids, which take the form of the container) and an invariant volume (in contrast to gases/vapors) in given temperature and pressure c...
