Stabilization at high temperatures

Journal of Polymer Science: Polymer Chemistry Edition, 1980
AbstractA general detailed model of polymer oxidative degradation in the presence of a stabilizer‐oxygen acceptor was considered. The motion of the degradation zone boundary and the sample lifetime were obtained for various conditions of the process. In particular, it is shown that within the given concentration immobile oxygen acceptor has the best ...

Temperature and Vascular Stability in Hemodialysis

Nephron, 1985
The temperature of the blood returning from an extracorporeal circuit may influence the vascular stability. Mean arterial blood pressure, heart rate and the temperature in the in-and outlet lines for blood and dialysis fluid of the dialyzer (TBa, TBv, TDi and TDo) were continuously measured in 8 patients suffering from vascular instability during ...

Stability of Procalcitonin at Room Temperature

Clinical Laboratory, 2014
The aim was to assess procalcitonin (PCT) stability after two days of storage at room temperature.Samples were collected from febrile children aged 7 to 92 days and were rapidly frozen after sampling. PCT levels were measured twice after thawing: immediately (named y) and 48 hours later after storage at room temperature (named x).

High‐temperature stability in yttria‐stabilized zirconia

Heat Transfer—Asian Research, 2008
AbstractYttria‐stabilized zirconia has been studied as a candidate standard reference material for the determination of thermal properties. This study evaluated the high‐temperature stability, which is important for yttria‐stabilized zirconia to be used for a standard reference material, using a common material of fine ceramics, Referceram ZR1 ...

Temperature stabilized multivibrator bridge

Journal of Physics E: Scientific Instruments, 1972
Two identical, astable multivibrators synchronized together form a temperature stabilized, fairly linear bridge, which may be used for balanced/unbalanced measurement of the R or C parameters of resistors, capacitors or transducers of nonelectric quantities. Theoretical and experimental analyses are given.

Influence of Temperature on Stability of Electrostatically Stabilized Alumina Suspensions

Journal of Colloid and Interface Science, 2000
Pure electrostatically stabilized aqueous alumina suspensions were prepared at various solid loadings in order to study the influence of temperature on the surface charge properties and rheology. Surface charge density at various temperatures was measured through potentiometric titration, and the analysis of the potentiometric data was accomplished ...

Plant diversity stabilizes soil temperature

2023
Extreme weather events are occurring more frequently, and research has shown that plant diversity can help mitigate impacts of climate change by increasing plant productivity and ecosystem stability1,2. Although soil temperature and its stability are key determinants of essential ecosystem processes related to water and nutrient uptake3as well as soil ...

Determination of sample temperature and temperature stability with 129Xe NMR

Journal of Magnetic Resonance, 2006
The (129)Xe chemical shift of xenon dissolved in isotropic liquids is very sensitive to solvent density, which in turn is dependent on the sample temperature. Therefore, the (129)Xe chemical shift can be used as the basis of a thermometer for measuring actual sample temperatures in NMR experiments.

High Temperature Stability of SmTM Magnets

7th Joint MMM-Intermag Conference. Abstracts (Cat. No.98CH36275), 1998
To meet the demand for permanent magnet materials usable up to 450–500 °C, we investigated and reported that a SmTM magnet with a low temperature coefficient of coercivity and a moderately high coercivity has substantially lower irreversible losses at elevated temperatures than conventional Sm2TM17 magnets.

Low Temperature Stability of Cubic Zirconia

physica status solidi (a), 2000
A 9 mol% Y 2 O 3 -stabilized ZrO 2 specimen was annealed in boiling water for 1200 h, and the phase structure was examined by XRD and the chemical states of zirconium, yttrium and oxygen were examined by XPS. After annealing, the phase of the specimen remains entirely cubic, and the chemical states of the elements are not remarkably changed ...
