A Kinetic 14-Vertex Model for (2+1)D-Crystal Growth
نویسنده
چکیده
Some dynamic properties of a fourteen-vertex model defined on the bcc(001) surface are investigated with Glauber kinetics. Exact results are given for small-size versions of the model. Using Monte-Carlo simulations on large systems and the Becker-Doering law behaviour of the growth rate in the 2D-nucleation theory, a non-equilibrium phase diagram is

Fermentative Lactic Acid Production by Lactobacilli: Moser and Gompertz Kinetic Models
Lactic acid production in a batch submerged fermentation process by five Lactobacilli: bulgaricus, casei, lactis, delbrueckii and fermentum in lactose fortified whey culture were investigated. Kinetic behavior of Lactobacilli growth rate and lactose utilization was studied based on the Moser and Gompertz kinetic models. Trendline tool in Excel software was applied for fitness assessment of the ...
متن کاملDetermination of Crystal Growth Rate and Morphology of Barium Carbonate Crystals in a Semi-batch Crystallizer
A semi-batch crystallization system is used to determine growth kinetics and morphology of barium carbonate crystals, under a constant pH value and constant temperature in the various relative supersaturations. Results show that crystal growth rate satisfies a first-order kinetic expression at high relative supersaturation, while at relative supersaturation values lower than 3, the k...
متن کاملEffect of Temperature and pH on Formulating the Kinetic Growth Parameters and Lactic Acid Production of Lactobacillus bulgaricus
Background and Objectives: Lactobacillus delbrueckii ssp bulgaricus is widely used in dairy industries as a starter for yogurt production. This study was designed using response surface methodology (RSM) in 12 batch pH-controlled cultures of Lactobacillus delbrueckii sub-ssp. bulgaricus for determining the effect of temperature and pH on the biomass production of a native strain of L. bulgaricu...
متن کاملApplication of Magnetic-modified Fe3O Nanoparticles for Removal of Crystal Violet from Aqueous Solution: Kinetic, Equilibrium and Thermodynamic Studies
The prepared magnetic-modified Fe3 O4 nanoparticles (Fe3 O4 -TAN) were used as adsorbent for removal of crystal violet (CV) from water solution. The effects of pH, contact time, dye concentration and temperature on adsorption were determined. The experimental data were analyzed using the Langmuir adsorption model. The data fitted well to the model with maximum adsorption capacities 84.0 mg/gund...
متن کاملA microstructural dry-snow metamorphism model for kinetic crystal growth
Historically, dry-snow metamorphism has been classified by the thermal environment and thermodynamic processes in a snowpack. Snow experiencing predominantly macroscopic isothermal conditions develops different microstructure than snow subjected to large temperature gradients. As such, much previous research has been categorized by and limited to specific thermal conditions. The current researc...
