Dynamic Viscoelasticity of Various Polyvinylchloride-Resins at Low Temperatures

Dynamic Orientation of Nuclei at Low Temperatures

A study has been made of the mechanisms of dynamic polarization of nuclei in organic materials at temperatures below 1 K and in magnetic fields up to 50 kG. After a summary of the mechanisms of dynamic polarization, the experimental results on 1,2-propanediol, doped with paramagnetic Crv complexes, are compared quantitatively with a spin temperature model of Borghini, in which it is assumed tha...

Calculation of MnO Activity in Aluminate Slags at Various Temperatures

In this research, the activity of MnO, produced during steel making in aluminate-rich slags, was investigated. According to thermodynamic equations and mathematical calculation, a series of relations was obtained for evaluation of oxide activity using Masson’s theory. The obtained relations were solved according to Levenberg- Marquardt method and using Matlab software. The results were correlat...

Sample environment at low temperatures

2014 A review of low temperature techniques as applied to neutron scattering studies is presented. Methods of temperature measurements especially carbon thermometry are discussed. Problems of heat transfer are treated in detail for different kind of samples and some solutions are proposed. Revue Phys. Appl. 19 (1984) 677-683 SEPTEMBRE 1984, The number of neutron scattering studies at temperatur...

Reset Noise at Low Temperatures

This paper presents results of the measurement and modelling of reset noise in charge-detection circuits of detector array multiplexers at low temperatures. To explain the temperature dependence of reset noise, it is proposed to take into account the source of noise associated with emission of electrons from interface states under the gate of reset transistor. It was found that at very low temp...
