Fundamental kinetic aspects of the decomposition of mixtures and double salts of ammonium nitrate and ammonium sulfate were
studied. The effect of water and sulfuric acid additives on the thermal decomposition rate of ammonium nitrate and sulfate
mixtures was examined. The constant of proton exchange between nitric acid and the sulfate anion in molten ammonium nitrate
was estimated. 相似文献

ThermoData Engine (TDE) is the first full-scale software implementation of the dynamic data evaluation concept, as reported recently in this journal. In the present paper, we describe development of an algorithmic approach to assist experiment planning through assessment of the existing body of knowledge, including availability of experimental thermophysical property data, variable ranges studied, associated uncertainties, state of prediction methods, and parameters for deployment of prediction methods and how these parameters can be obtained using targeted measurements, etc., and, indeed, how the intended measurement may address the underlying scientific or engineering problem under consideration. A second new feature described here is the application of the software capabilities for aid in the design of chemical products through identification of chemical systems possessing desired values of thermophysical properties within defined ranges of tolerance. The algorithms and their software implementation to achieve this are described. Finally, implementation of a new data validation and weighting system is described for vapor-liquid equilibrium (VLE) data, and directions for future enhancements are outlined. 相似文献

ThermoData Engine (TDE) is the first full-scale software implementation of the dynamic data evaluation concept, as reported recently in this journal. In the present paper, we describe the development of a World Wide Web-based interface to TDE evaluations of pure compound properties, including critical properties, phase boundary equilibria (vapor pressures, sublimation pressures, and crystal-liquid boundary pressures), densities, energetic properties, and transport properties. This includes development of a system for caching evaluation results to maintain high availability and an advanced window-in-window interface that leverages modern Web-browser technologies. Challenges associated with bringing the principal advantages of the TDE technology to the Web are described, as are compromises to maintain general access and speed of interaction while remaining true to the tenets of dynamic data evaluation. Future extensions of the interface and associated Web-services are outlined. 相似文献

The kinetic regularities of the thermal decomposition of dinitramide in aqueous solutions of HNO3, in anhydrous acetic acid, and in several other organic solvents were studied. The rate of the decomposition of dinitramide
in aqueous HNO3 is determined by the decomposition of mixed anhydride of dinitramide and nitric acid (N4O6) formed in the solution in the reversible reaction. The decomposition of the anhydride is a reason for an increase in the
decomposition rates of dinitramide in solutions of HNO3 as compared to those in solutions in H2SO4 and the self-acceleration of the process in concentrated aqueous solutions of dinitramide. The increase in the decomposition
rate of nondissociated dinitramide compared to the decomposition rate of the N(NO2)2
− anion is explained by a decrease in the order of the N−NO2 bond. The increase in the rate constant of the decomposition of the protonated form of dinitramide compared to the corresponding
value for neutral molecules is due to the dehydration mechanism of the reaction.

Optimization of geometry and surface modification of microchip input reservoirs were performed to achieve uninterferenced pressure-induced sample injection of multiple samples into microreactors using a single syringe pump. Nine samples of 3.5 microL were pipetted onto input reservoirs and loading of PCR mixture into 260 nL microreactors was achieved followed by successful PCR amplification, confirming that no cross-contamination occurs during injection. 相似文献

The influence of exchange coupling of layers on the propagation of magnetostatic dipole volume waves in normally and tangentially
magnetized two-layer epitaxial ferrite structures is investigated. It is shown that the indicated influence is manifested
in the form of dynamic spin pinning effects on the interlayer boundary and formation of a common dipole-exchange wave spectrum
for the entire structure. In this case, at the synchronism frequencies of the dipole and exchange waves the losses of the
dipole waves grow and anomalous segments appear in the dispersion. In films magnetized in the “hard” direction relative to
the axis of normal uniaxial surface anisotropy the magnetostatic dipole volume waves can interact resonantly with the surface
spin waves supported by the boundaries with pinned spins.
