Thermodynamic properties of n-hexane

Specific volumes and isobaric heat capacity measurements are reported for n-hexane. The measurements were made in the liquid and vapor phases at temperatures from the triple point and also cover a wide region around the critical point. The thermal, caloric, and acoustic data from our own investigation as well as those of a number of other authors are fitted to a single equation of state with 32 constants. This equation yields to all thermodynamic properties of n-hexane in the temperature range 180 to 630 K and pressures up to 100 MPa. The data in the critical region have been analyzed in terms of a scaled equation of state.     

Construction and design principles for micro-processor-based conductometric analyzers

We consider questions connected with design of microprocessor-based conductometric analyzers and cases of the utilization of microprocessor technology to design automated instruments for analytical control.Translated from Izmeritel'naya Tekhnika, No. 11, pp. 68–70, November, 1994.     

The mechanism and kinetics of formation and decomposition of magnesium hydride

The formation and decomposition of magnesium hydride was studied in the temperature range 610–630 K and at pressures from the equilibrium value to 1.6 MPa. The formation of a chemisorbed hydrogen layer on the sample surface seems to be the first important step of the hydriding process. Further hydriding is developed due to nucleation and growth rather than the coating hydride layer growing. We demonstrate that the dehydriding rate can be decreased by treating a sample at p_eq; this phenomenon proves the model proposed.
