Kinetics of Physical Transformations
1984A concrete physical system may change in time. Any such change will be called a process, provided the change exists in every inertial coordinate system. In this broad sense, not only chemical reactions, positron—electron ‘annihilation’, nuclear reactions, etc., but also the emission and absorption of photons, and even a change in a purely mechanical ...

Kinetics of anisothermal phase transformations
Journal of Applied Physics, 1983An analytical study of anisothermal phase-transformation kinetics is described. In particular, the familiar Johnson–Mehl–Avrami equation is generalized to the situation for which temperature increases linearly with time. An exact analysis of the problem is carried out, with the general solution being obtained in terms of one of Horn’s confluent ...

Dissipation potential of four algae viz. Haematococcus pluvialis, Selenastrum capricornutum, Scenedesmus quadricauda and Chlorella vulgaris was investigated against ten antibiotics (sulfamerazine, sulfamethoxazole, sulfamonomethoxine, trimethoprim ...

Quantum-Mechanical Kinetic Energy Transformation
Physical Review, 1958It is shown by a transformation of the usual expression for the kinetic energy matrix elements a simpler formula results which yields, for numerical wave finctions, higher numerical accuracy for the kinetic energy than has previously been obtained. The derivation of the transformation and the numerical results of several applications are presented ...

Metal-hydride transformation kinetics in Mg nanoparticles
Applied Physics Letters, 2009The hydrogen sorption kinetics of magnesium nanoparticles prepared by inert gas condensation and coated by a magnesium oxide layer were investigated by a volumetric apparatus. The metal-hydride transformation was studied by transmission electron microscopy of the nanoparticles both in the as-prepared state and after hydrogen cycling.

Soil Science Society of America Journal, 1981
Abstract Phosphorous in concentrations exceeding those generally observed through agricultural activities has been encountered at land application wastewater treatment sites. To predict the environmental impact of these systems, a model was developed to describe the reaction of orthophosphate with mineral soils ...

Transformation kinetics during continuous cooling
Acta Metallurgica, 1956Abstract It is shown that transformations which nucleate heterogeneously will quite often obey a rule of additivity and transform nonisothermally according to simple rate laws which can be calculated from isothermal transformation data.

Kinetic modes of polymorphic transformations
Journal de Physique IV (Proceedings), 2003The paper suggests a unified approach for the interpretation of the different kinetic types (athermal martensitic, isothermal martensitic, bainitic, normal) of polymorphic transformations based on the analysis of experimental data obtained at normal and high pressures.

Kinetic equations and Lorentz transformation
Physica, 1968Abstract It is known that, within the canonical formulation of statistical mechanics initiated by Dirac and developed by the author and Kotera, the Liouville equation is invariant under Lorentz transformations. As a direct consequence, it is shown that the general master equation, which is conceptually equivalent to the Liouville equation, is also ...

Diffusional Transformations: Microscopic Kinetic Approach
2005The term “diffusional transformations” is used for the phase transformations (PTs) of phase separation or ordering of alloys as these PTs are realized via atomic diffusion, i.e., by interchange of positions of different species atoms in the crystal lattice. Studies of kinetics of diffusional PTs attract interest from both fundamental and applied points
