Emission of low concentration methane from natural gas vehicle and coal mine is becoming an urgent issue, because of its low explosive limit in air and the strong greenhouse effect of methane.61 Toward this end, catalytic combustion of methane at low temperature is an effective strategy.62 Becaus...
Why would a 1 M solution of MgSO4 have greater conductivity than a 1 M solution of NaCl when dissolved in water, and would it be correct to argue that multiple charged ions present in MgSO4 contribute to this difference in conductivity? Explain why aspirin is more soluble in ethanol than ...

The method of Dionisio-Sese and Tobita39was followed to determine electrolyte leakage. Fresh leaf discs in test tubes containing 10 mL of double-distilled water were analyzed for their electrical conductivity (EC0). The sample tubes were boiled at 50 °C and 100 °C for 20 and 10 ...
Besides the outstanding lubrication properties, the excellent corro sion resistance is another advantage for the utilization of a-C:H films in marine environments, because of the high hydrophobicity, chemical inertness, and low electrical conductivity [3,13,14]. However, the corrosion resistance ...
Soil thermal conductivity is a key factor governing its thermal regime. In the present study, we measured the thermal conductivity of Toyoura sand and glass beads using a heat probe method to clarify the effects of gravimetric water content ( w ) and NaCl concentration ( C ) and to ...
1/T The A's of LaCl3-NaCl and LaCl3-KCl decrease drastically with increasing LaCl3 concentration. A of molten LaCl3 is smaller than that of molten CaCl2, in which the octahedral complex anion CaCl4-6 is known to exist. It seems reasonable to assume that complex ions or cluster species...
Results of the analysis show that the high-frequency conductivity of doped NaCl is completely due to the dipole relaxation. The dipoles concentration was estimated as 25-50 ppm slightly increasing with temperature in the temperature range 120-220 degreesC in accord with the expected one from the ...
