Mixed mode interface crack in a pure power-hardening bimaterial
Analytical and numerical analysis of the dominant singularity solutions of the stress and strain field near an interface crack in a pure power-hardening bimaterial indicates that the crack stress singularity i...

Crystallizability and sinterability of a precursor prepared by oxalate method in ethanol solution
A precursor of yttria-stabilized zirconia (YSZ) powder was prepared by the oxalate method in ethanol solution. The crystallizability and sinterability of the precursor were studied. The crystallizability of th...

Chapter
Thermomechanics of Molecular Networks and Rubberlike Materials
On simple elongation, rubberlike materials are capable of undergoing very large reversible elastic deformations. The modulus of elasticity, which unlike solids is strongly dependent on deformation, is some ord...

Chapter
Thermal Behavior of Solid Polymers During Fracture
The fracture of polymers is inevitably accompanied by thermal events. The sources of the thermal events may be both the deformational processes and the rupture of macromolecules. Pure elastic (brittle) fractur...

Chapter
Heat Capacity
The heat capacity of any solid body is determined by the normal modes of vibrations available to its structure. If the spectrum of vibrational states, ρ(ω)dω, which gives the number of modes of vibration whose fr...

Chapter
Thermal Expansion
Thermal expansion, or more widely thermal deformation, is characterized by the changes of the dimensions of a body resulting from the temperature changes. Similar to the thermal conductivity, the thermal expan...

Chapter
Thermomechanics of Glassy and Crystalline Polymers
Conventionally, the deformation of solids is treated within the framework of elasticity theory in terms of stresses and strains, i.e. in purely mechanical terms. Although experimental determination of stress-s...

Chapter
Thermodynamic Behavior of Solid Polymers in Plastic Deformation and Cold Drawing
The mechanical work spent on the irreversible deformation of solids is always at least partly dissipated. Therefore, independent of the sign of the heat effect resulting from the elastic deformation, plastic d...

Chapter
Experimental Methods and Instrumentation
Three types of measurements are usually used for the study of the thermal behavior of polymers under deformation: the temperature changes resulting from the deformation of the sample, the temperature dependenc...

Chapter
Thermal Conductivity
Most polymers are insulating systems, therefore, any electronic effects are absent in them and heat conduction occurs as a result of lattice vibrations. Theoretical consideration of the thermal conductivity of...

Chapter
Experimental Methods and Instrumentation
Two methods are usually used for the determination of the heat capacity of polymers over a wide temperature range: adiabatic calorimetry and differential scanning calorimetry (DSC).

Ionization Radiation Effects and Mechanisms
A systematic approach for predicting radiation stability of materials and devices is presented. The conceptual basis is a consideration of the radiolysis potentially occurring in x-ray-irradiated materials as ...

Bragg Reflection and Phonon Folding Effects on Hop** Magnetoconductance in Superlattices
Transport in quantum microstructures (QMS) manifests such fundamental phenomena as quantum interference and electron localization. QMS can be designed to achieve arbitrary spectra of electronic states and are ...

Investigation on New Types of Semiconducting Ceramic Gas Sensors
A series of new types of semiconducting ceramic gas-sensing materials, Al2O3-based semiconducting ceramics, have been invented. Hydrogen and methane gas sensors have been made from these materials with different ...

Theory of long-scale cooperative relaxation of polymer networks. Hydrodynamic interaction effects
The theory of relaxation properties of polymer networks is considered for specific long-scale cooperative motions of network chains, which have characteristic scales greater than chain dimensions between cross...

Long-scale conformational properties of peptide chains in β-sheets
We propose a sufficiently simple multichain model of ordered β-sheets, composed of extended macromolecules with rigid elements. The effective constants of intra- and interchain interactions describe primary a...

Alignment of Rigid-Rod Polypeptide Chains by Solvent Quenching
We introduce a simple “solvent quenching” approach to align the rigid-rod à-helical poly(α-benzyl-L-glutamate) (PBLG) chains in the surface-grafted monolayer. By sequentially treating with a good solvent and a...

Contribution of dynamic charging effects into dopant contrast mechanisms in silicon
In this work, SEM capability for imaging of both p- and n-doped regions in Si was demonstrated. The best dopant contrast was found when the primary electron range (R) is comparable or larger than the maximum esca...
