Self-consistent minimum free-energy calculations of the structure and lattice dynamics of forsterite at high pressure (up to 30 GPa) and high temperature (up to 1850 K) have been performed using an approach based on the Born model of solids. In the free-en ...
Two-dimensional (2D) exchange NMR is a powerful tool for measuring the dynamics and energetics of adsorbed xenon atoms undergoing slow exchange between the alpha-cages of Na-A zeolite. In this proceedings, we present recently published results, as well as ...
The equil. Br2(g) + 2NO(g) .dblarw. 2BrNO(g) was studied at 275-363 K. Third-law calcns. lead to DH Deg298(1) = -11.50 +- 0.17 kcal/mol, from which DH Degf298(BrNO, g) = 19.52 +- 0.24 kcal/mol and D Deg0(Br-NO) = 27.90 +- 0.30 kcal/mol. Absorption bands of ...
The recombination of I atoms after laser flash photolysis was studied in the presence of NO or NO2 at 320-450 DegK and 0-200 atm of He. The reaction proceeds in 2 stages. The 1st stage is governed by the recombination I + NO (+He) -> INO (+He) or I + NO2 ( ...
In engineering practice, thermodynamic, economic and environmental aspects are taken into account either separately or in some limited combination during the different stages of energy system synthesis, design and operation. It would be beneficial, however ...
Oxygen diffusion is treated in a dense electronically conducting cobaltate pellet blocked ionically on one surface, electronically on the other, and sealed on its cylindrical periphery. A procedure is developed for extracting the chemical diffusion and sur ...
Chemical diffusion (D) and surface exchange (k) coefficients for SrFeO3-delta were measured using an electrochemical cell combined with electrochemical impedance spectroscopy (EIS) and potential step technique (PS) in the temperature range of 850-915°C. A ...
