Photoconductive polymers: Structure, mechanisms and properties
Die Angewandte Makromolekulare Chemie, 1990AbstractCharge carrier transport properties of organic polymers can vary over a wide range. The paper shows that the electron‐ and hole mobilities of polymers with pendant photoconductive groups (i. e. carbazole) are on the order of 10‐6 cm2/Vs. In these materials the flow of electronic charge is maintained by the overlap of the π‐orbitals of the ...

Structure and mechanical properties of Silumin
Metal Science and Heat Treatment, 19761. The reason for the low plasticity, and in some cases the hardness, of Silumins is the brittleness of silicon particles of lamellar form. These platelets break by splitting even with small plastic deformation of the α matrix. Because of the substantial volume of these silicon particles in the structure of the alloy they have a large effect on ...

Structural properties of cellulose and cellulase reaction mechanism
Biotechnology and Bioengineering, 1983AbstractThe effects of structural properties and their changes during cellulose hydrolysis on the enzymatic hydrolysis rate have been studied from the reaction mechanism point of view. Important findings are the following: (1) The crystallinity index (CrI) of partially crystalline cellulose increases as the hydrolysis reaction proceeds, and a ...

The Structure and Anisotropic Mechanical Properties of Bone
IEEE Transactions on Biomedical Engineering, 1984Compact bone can be modeled as a complex hierarchical composite interrelating both structure and material properties on four levels of structural organization: molecular, ultrastructural, microscopic, and macroscopic.

Hierarchical structure and mechanical properties of remineralized dentin
Journal of the Mechanical Behavior of Biomedical Materials, 2014It is widely accepted that the mechanical properties of dentin are significantly determined by its hierarchical structure. The current correlation between the mechanical properties and the hierarchical structure was mainly established by studying altered forms of dentin, which limits the potential outcome of the research.

Carbon fibres: Structure and mechanical properties
International Materials Reviews, 1994AbstractThe fine structure of carbon fibres varies between the high strength and the high Young's modulus varieties based on detailed examination of X-ray and electron microscope studies. Techniques for measuring the tensile properties of fibres and composites are well developed, but the same is not true for compressive properties.

Polymer molecular structure and mechanical properties
Philosophical Magazine, 1965Abstract The theoretical problem of relating the mechanical properties of a polymer to molecular structure is considered for the simplest case where an amorphous polymer is subjected to a hydrodynamic stress system at high rates of deformation. The theoretical basis is that under such conditions the mechanical properties can be attributed to the London

Structure and Mechanical Properties of Plastics
1956The characteristic structural feature of polymeric systems which leads to their remarkable mechanical properties is the existence of long chain molecules endowed with Brownian movement. The thermal motion may be thought of as translation of molecular segments with rotation around chain bonds. The translations and rotations of individual segments within
