Temperature dependent network properties of amorphous PCT during tensile stretching
Polymer, 2020Abstract Tensile deformation behavior of amorphous Poly (1,4-cyclohexylenedimethylene Terephthalate) (PCT) at 25 °C–108 °C was investigated by means of in situ synchrotron wide-angle X-ray scattering (WAXS). WAXS patterns were processed in a way that the scatterings from isotropic and anisotropic structures were separated.

Viscosity‐Temperature Dependence on DNA Stretching: Slalom Chromatography Study
Journal of Liquid Chromatography & Related Technologies, 2003Slalom chromatography (SC) is a chromatographic procedure for the separation of polymers, which is based on a non equilibrium principle. A novel equation was recently developed to model the retention variation of linear double stranded DNA molecules with the mobile phase velocity under SC.

Release of atrial natriuretic factor. Effects of repetitive stretch and temperature
American Journal of Physiology-Renal Physiology, 1986The effect of continuous and repetitive mechanical stretch on release of immunoreactive atrial natriuretic factor (IR-ANF) was studied in isolated rat atria distended by inflation of miniature balloon catheters. After 10 min incubation, the concentration of IR-ANF in the medium increased in proportion to the degree of continuous atrial stretch ...

Rise of Temperature on Fast Stretching of Butyl Rubber
Rubber Chemistry and Technology, 1945Abstract Study of the rise in temperature by fast stretching of Butyl gum and tread stocks throws considerable light on crystallization, internal friction, and carbon black reënforcement as functions of elongation and other possible variables. For low elongations, the low-heat curves show the occurrence of thermoelastic inversion.

Temperature dependence of transient photoconductivity in stretched trans-polyacetylene films
Solid State Communications, 1988Abstract The temperature dependence of picosecond and steady state photoconductive response has been measured for an highly oriented form of trans-polyacetylene. When the direction of the external dc field is parallel to the chain direction the fast response is independent of temperature while for current flow perpendicular to the chains the fast ...

Temperature distribution in stretching/shrinking fin with variable parameters
Heat TransferAbstractIn this paper, we consider a mathematical model, which has a unique mechanism of heat transfer in the stretching/shrinking straight fin with an exponential profile. The thermal conductivity, internal heat generation, and heat transfer coefficient are considered temperature‐dependent.

Temperature dependence of grain-boundary strain on stretching polycrystalline lead
Soviet Physics Journal, 1988High-purity polycrystalline lead has been used to examine grain-boundary slip (GBS), boundary migration, and the relationship to other strain mechanisms on stretching in the range 0.1–0.9Tmp. There are two stages in the temperature dependence of the grain-boundary slip, with the junction around 0.5Tmp. The low-temperature one reflects the accommodation

Effect of Temperature on Isolated Stretch-Receptor Organ of the Crayfish
Science, 1959Abdominal stretch-receptor organs of Astacus leptodactylus are investigated by means of extra- and intracellular leads. The effects of changing temperature on steady-state rate of activity are surprisingly low. The sensory nerve cell compensates for changes in temperature by means of opposite reactions of generator ...

Temperature effect on the recovery process in stretched Bombyx mori silk fibers
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2016The recovery process in stretched Bombyx mori silk fibers at different strain levels from 3% to 17% was investigated at room conditions during long period of time from 5min to 20days and more. How the temperature affects the recovery process in the silk fibers stretched at room conditions was examined at temperatures from 25 to 125°C.
