Molecular Dynamics Membrane Distillation

Abstract The rate of heat and mass transfer through distillation membranes is typically estimated using an over-simplified, straight-cylindrical-pore approach coupled with several empirical correction factors that are included to compensate for the simplicity of the approach. In the present work, we have calculated for the first time the rate of transport of heat and mass …

Aug 31, 2016 Over the last 30 years, detailed atomistic molecular modeling techniques, namely, the molecular dynamics (MD) and the Monte Carlo (MC), have become a widely used method for the investigation of the molecular structure of membrane materials and transport properties in various membrane operations (Binder 1995; Gubbins and Moore 2010; Hofmann …

Computer simulation, specifically molecular dynamics (MD) simulation, pro- vides such a tool of exploring the membrane protein dynamics with atomistic and femtosecond resolutions. MD simulation of biomolecular system is based on classic Newton’s equation of motion and empirical potential energy functions.

Here we present the first molecular dynamics study of an amphipol-stabilized membrane protein, using Escherichia coli OmpX as a model. We begin by describing the structure of the complexes formed by supplementing OmpX with increasing amounts of A8-35, in order to determine how the amphipol interacts with the transmembrane and extramembrane ...

In the research reported in this paper, membrane distillation was employed to recover water from a concentrated saline petrochemical effluent. According to the results, the use of membrane distillation is technically feasible when pre-treatments are employed to mitigate fouling. A mathematical model was used to evaluate the fouling mechanism, showing that the deposition …

May 23, 2022 However, the fouling mechanism and dynamics were influenced by the type of pre-treatment used (filtration or filtration associated with a pH adjustment). By employing filtration and adjusting the solution pH, a fouling formation could be mitigated in membrane distillation when processing concentrated saline effluent.

Membrane distillation AGMD Membrane Membrane Distillation (MD) is a thermally-driven separation process, in which only vapour molecules trans-fer through a microporous hydrophobic membrane. The driving force in the MD process is the vapour pres-sure difference induced by the temperature difference across the hydrophobic membrane. This process has

This paper reviews various enhanced conformational sampling methods and explicit/implicit solvent/membrane models, as well as their recent applications to the exploration of the structure and dynamics of membranes and membrane proteins. Molecular dynamics simulations have become an essential tool to investigate biological problems, and their ...
