Si3N4 single-crystal nanowires grown from silicon micro and nanoparticles near the threshold of passive oxidation
J. Farjas, C. Rath, A. Pinyol +2
A simple and most promising oxide-assisted catalyst-free method is used to prepare silicon nitride nanowires that give rise to high yield in a short time. After a brief analysis of…
Kinetic study of the oxide-assisted catalyst-free synthesis of silicon nitride nanowires
J. Farjas, A. Pinyol, Chandana Rath +2
The synthesis of Si3N4 nanowires from the reaction of silicon nanoparticles with N2 in the 1200-1440 C temperature range is reported. The nitridation conditions are such that the r…
Numerical model of solid phase transformations governed by nucleation and growth. Microstructure development during isothermal crystallization
J. Farjas, P. Roura
A simple numerical model which calculates the kinetics of crystallization involving randomly distributed nucleation and isotropic growth is presented. The model can be applied to d…
Simple approximate analytical solution for non-isothermal single-step transformations: kinetic analysis
Jordi Farjas, Pere Roura
In this paper, we develop a method for obtaining the approximate solution for the evolution of single-step transformations under non-isothermal conditions. We have applied it to ma…
Modification of the Kolmogorov-Johnson-Mehl-Avrami rate equation for non-isothermal experiments and its analytical solution
Jordi Farjas, Pere Roura
Avrami's model describes the kinetics of phase transformation under the assumption of spatially random nucleation. In this paper we provide a quasi-exact analytical solution of Avr…
Cell size distribution in a random tessellation of space governed by the Kolmogorov-Johnson-Mehl-Avrami model: Grain size distribution in crystallization
Jordi Farjas, Pere Roura
The space subdivision in cells resulting from a process of random nucleation and growth is a subject of interest in many scientific fields. In this paper, we deduce the expected va…
