A Molecular Dynamics Study Of Structural Modifications Of Perarylphosphonium Based Ionic Liquids On The Melting Point, Johnathan Anderson
A Molecular Dynamics Study Of Structural Modifications Of Perarylphosphonium Based Ionic Liquids On The Melting Point, Johnathan Anderson
<strong> Theses and Dissertations </strong>
Several perarylphosphonium based mesothermal ionic liquids (ILs) have been shown to be stable at high temperatures for prolonged periods of time and with high heat capacities making them good candidates for use in many processes such as usage as a heat transfer fluid, as an absorbent for separation of aromatics from aliphatics, and as a solvent for high temperature reactions. Many, however, have melting points above 100o C, limiting their use. Recently, it was shown that the melting point of an IL can be lowered by simply increasing the dipole moment of the cation or by structurally rigidifying the …

Colloids are a ubiquitous class of materials composed of microscopic particles suspended in a continuous phase which are found in everyday products and in nature. Colloids are also useful models for studying the spontaneous arrangement of matter from individual building blocks to mesophases. Standard treatment of colloid science is based on the assumption of equilibrium conditions, as defined in traditional thermodynamics. However, novel assembly mechanisms and motility are unlocked by pushing colloids away from equilibrium using external energy. In addition, many colloids in nature and in industrial applications exchange energy and mass with the surrounding environment thus behaving in a …

The free-energy model can extend the lattice Boltzmann method to multiphase systems. However, there is a lack of models capable of simulating multicomponent multiphase fluids with partial miscibility. In addition, existing models cannot be generalized to honor thermodynamic information provided by any multicomponent equation of state of choice. In this paper, we introduce a free-energy lattice Boltzmann model where the forcing term is determined by the fugacity of the species, the thermodynamic property that connects species partial pressure to chemical potential calculations. By doing so, we are able to carry out multicomponent multiphase simulations of partially miscible fluids and generalize …
