Abstract:
At system pressures between 17 MPa and 25 MPa the nucleation and growth of NaCl nanoparticles in water at supercritical conditions was investigated by molecular dynamics simulations at different system temperatures and system densities. Our results show that particle formation takes place within a few hundred picoseconds after the jump from ambient to supercritical conditions. After nucleation a phase of growth by adding monomers is followed by growth via cluster-cluster collisions. We present results on the time development of distributions of cluster sizes, cluster compositions, and cluster temperatures as well as radial distribution functions and nucleation rates.

SN2 Reaction: Kinetics
In a chemical reaction, a relationship exists between the concentration of reactants and the rate at which the reaction proceeds. The study to measure this relationship is known as the kinetics of a chemical reaction. Kinetic studies are used to deduce the rate law of a chemical reaction, which provides information about the species involved during the transition state of the rate-determining step. Thus, kinetic studies help to derive the mechanism of a reaction.

Energetics of Solution Formation
When the strengths of the intermolecular forces of attraction between solute and solvent species in a solution are no different than those present in the separated components, the solution is formed with no accompanying energy change. Formation of the solution requires the solute–solute and solvent–solvent electrostatic forces to...
Crystal Growth: Principles of Crystallization
Initiating crystallization involves manipulating the concentration of the solute and the temperature of the solution. Since crystal growth occurs when the ratio of concentration and solubility of the solute in the solvent – the...
