The pressure effect on the thermopower has been investigated for the Bi1.8Sb0.2Te3.0 alloys. We have found an anisotropic pressure dependence on the thermopower for p- and n-type Bi1.8Sb0.2Te3.0 at room temperature. Along a-axis, for p-type, the thermopower value increased with increase of pressure at a rate of 13.9 %/Gpa, whereas, along c-axis, itkeeps approximately constant..

In this work, we present a study of phonon hardening of 762 cm-1 phonon which is the strongest Raman-active mode in pyrochlore Cd2Os2O7 single crystal through temperature dependent Raman scattering. We discuss that the major contribution of the phonon hardening and the anomarlie behavior of asymmetry Fano parameter would involve to spin-phonon coupling and electronphonon coupling.

In conventional partial resection of parenchymatous organs significant bleeding is one of the main problems, especially in neonates and infants. The patients rapidly lose considerable amounts of their small blood volume. Laser light leads to photo thermal effects in tissue and causes coagulation, drying up, carbonization and evaporization, depending on the temperature.

The derived temperature dependences of the peak intensities, separations and half-widths of the separate spectral peaks in the A-band phonon progressions indicate the different trends for vibration-free zero-phonon electronic transition and vibration-related lower-energy electronic transitions to high vibrational levels of the ground electronic state – lower thermal damping and more softened phonon for the zero-phonon transition, also implying the extended defect origin of the A-band photoluminescence.

Heat stress is a common reality in poultry production, its effects are quite complex and harmful and depend on the intensity and duration of the exposure to high temperatures. The gut is affected by heat stress through several pathways, including organ ischemia and hypoxia, as well as oxidative stress.

The induced magnetic properties and the interaction between the electrons in the valence and the conduction bands affect the positions of the energy band and the band-gap in DMS. The growth technology of DMS is quite sophisticated and the magnetic properties mainly depend on the impurity concentrations of the properly grown multicomponent compounds.

The temperature dependence of the bandgap energies of the QDQW’s core and well layer was well described using the Varshni expression. Evidence of the existence of “local wells” in the QDQW’s well layer that leads to a more significant change in the maximum position and full width at half maximum of the well’s emission peak compared to the core’s counterpart was discovered.

In this work, the temperature dependence of the anharmonic X-ray absorption fine structure (XAFS) and thermodynamic properties of the crystalline silicon (c-Si) have been investigated. The thermodynamic parameters are derived from the influence of the absorbing and backscattering atoms of all their nearest neighbors in the crystalline lattice with thermal vibrations.

In this paper, the temperature-dependent extended X-ray absorption fine structure (EXAFS) of distorted crystalline cadmium has been analyzed using an efficient calculation-model. The analysis procedure is based on evaluating the influence of temperature on the phase shift and amplitude reduction of EXAFS oscillation that is expressed in terms of the EXAFS Debye-Waller factor.
