چکیده

We report on dielectric test measurements of a rectangular flat sample holder which serves as capacitor and is aimed for simultaneous neutron (n-DE) spectroscopy acidic liquid samples. describe technical details the assembly equipment well preparation procedure air sensitive The was characterised off-line from spectrometer by spectroscopy, but using standard IN16B cryofurnace with stick 4-wire connection Novocontrol equipment, previously setup collaborative effort between ILL Roskilde University. Temperature-dependent scans samples (glycerol, glycerol-water, Milli-Q water) were measured in frequency range 0.27 Hz 1 MHz. Step-like temperature changes allowed to probe equilibrium conditions continuous made mimic typical backscattering fixed window scans. Both type carried out cooling heating. show that our suited n-DE-experiments. On other hand, scan phosphoric acid reveals limitations case high conductivities, also shows DC-conductivity can still be accessed sufficiently wide low where onset conductivity simultaneously probed change proton dynamics seen spectroscopy.

Formula for Viscosity of Glycerol-Water Mixture

An empirical formula is proposed for the calculation of the viscosity of glycerol-water mixture for mass concentrations in the range of 0-100% and temperatures varying from 0 to 100 C. It compares well with three databases available in the literature and its application procedure is also simpler than other previously-developed correlations. Introduction Many industrial applications require know...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Dielectric relaxation in dimethyl sulfoxide/water mixtures studied by microwave dielectric relaxation spectroscopy.

Dielectric spectra of dimethyl sulfoxide (DMSO)/water mixtures, over the entire concentration range, have been measured using the transmission line method at frequencies from 45 MHz to 26 GHz and at temperatures of 298-318 K. The relaxation times of the mixtures show a maximum at an intermediate molar fraction of DMSO. The specific structure of mixtures in different concentration regions was de...
