The thermal conductivities were found to increase linearly with pressure, and the increase rates relative to their zero-pressure values were 3.1, 0.68, 0.39 and 0.90% per kbar for NaCl, MgO, coesite and stishovite, respectively. On the thermal conductivity of coesite, the pressure dependence ...
摘要 Abstract:Understanding the microscopic ionic structure and thermal properties of the NaCl-CaCl2 mixture is of great importance for improving its photothermal energy conversion efficiency. However, the measured values of thermophy...
The thermal conductivity average value was 1.037 ± 0.074 W/m−1·°C−1. The weight loss of NaCl–KCl–NaF eutectic salt is still less than 6.0% even up to 900 °C and the eutectic salt have very excellent thermal stability. The NaCl–KCl–NaF eutectic salt with high latent and ...
Electron micrographs of the fine structure of the cells were obtained, and no significant changes in electrical conductivity were observed at low salt concentrations. However, major changes in cell ultrastructure were observed at 300 and 400 mmol / L. Additionally, osmoregulatory substances and ...
Measurements of electrical conductivity of NaCl ∶ 10 −5 molar fr. CaCl2 ∶ (1–80)×10 −5 molar fr. Na 2 CO 3 crystals have been used to determine the temperature dependence of the solubility of CO 3 -ions over the temperature range from 75 to 530 °C. The total solubility of...
Hydroxyapatite was washed with doubly distilled water until the constant conductivity about 0.5 µS/cm was achieved. 2.1 Methods of measurements The specific surface area and porosity of the prepared sam- ples of hydroxyapatite were determined from the nitrogen adsorption/desorption data. The...
conductivity, as EC values were twice as high as control values. In general, roadside and park soils differed significantly (p < 0.001) in both parameters. Moreover, values of soil pH (in H2O) strongly correlated with electrical conductivity (p < 0.001) (n = 30): R =...
Thermal conductivity measurements via time-domain thermoreflectance for the characterization of radiation induced damage The progressive build up of fission products inside different nuclear reactor components can lead to significant damage of the constituent materials. We de... R Cheaito,CS Gorham,A Mis...
The ion chromatography system was a Dionex ICS 2000 system (Dionex, the USA) equipped with a DS6 conductivity detector, an ASRS-ULTRA Anion Suppressor, an AS19 separation column (250 mm × 4 mm), a Dionex IonPac AG19 guard column (50 mm × 4 mm), and a Chromeleon 6.50 chromatography...
As the lightest structural engineering material, magnesium (Mg) has drawn considerable attention for its applications in aeronautical, automobile and electronic industries because of its superior machinability, thermal conductivity and ratio between yield strength and density. It also shows great potential ...
