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 ...

Temperature stabilized optical waveguide modulator

Optical and Quantum Electronics, 1978
A low drive-voltage optical modulator using a Ti-diffused UNbO3 optical waveguide has been fabricated. Stabilization against ambient temperature change was realized by using a miniature halfwave plate. The halfwave voltage, 3 dB bandwidth, optical insertion loss and extinction ratio were 3·8 V (at 1·06μm wavelength), 850 MHz, 10 dB and 13 dB ...

Temperature anisotropy stabilization of ion temperature gradient instabilities

Physics Letters A, 1988
Abstract The effect of ion temperature anisotropies on the ion temperature gradient instability (“ion mixing mode”) is investigated in a shearless slab geometry. The roles played by the parallel and perpendicular (to the equilibrium magnetic field) components of the temperature are described and modified stability diagrams are presented.

Temperature compensation of transistor stabilizers

Measurement Techniques, 1961
The above computation of the temperature compensation for transistor stabilizers makes it possible to construct devices with highly-stable output voltages. It is best to use for temperature compensation germanium or silicon diodes in a forward connection, using the above-described method for accurate adjustment of temperature compensation.
