Zwitterionic methacrylate polymers with either choline phosphate (CP) (poly(MCP)) or phosphorylcholine (PC) (poly(MPC)) side groups were analyzed to characterize the bound hydration water molecules as nonfreezing (NFW), intermediate (IW), free (FW). This characterization was carried out by differential scanning calorimetry (DSC) of polymer/water systems, and enthalpy changes cold crystallization melting determined. The electron pair orientation CP is opposite that PC, former binds alkyl...
Time evolution of the microscopic wetting velocity 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (EMI-TFSI) or water on a micrometer-scale line-patterned surface with poly(3-sulfopropyl methacrylate) brush and hydrophobic perfluoroalkyl monolayer was precisely measured by direct observation using optical microscopy selective dyeing method over long period (178 days). When liquid droplet placed dyed surface, penetrated spread into polymer layer, forming precursor thin film...
The relationship between the solvent–solute interaction and permeation properties is fundamental in development of forward osmosis (FO) membrane. In this study, we report on quantitative reproduction flux, which has different interactions, through modeled FO membrane by non-equilibrium molecular dynamics (NEMD). effect was investigated changing interatomic solute solvent. calculated semi-permeable membrane, solvent solution equal to that solutions, consistent with theoretical curve derived...
The modification of an interlayer layered materials by intercalation with organoammonium ion has been a promising method to control the polarity two-dimensional nanospace. Montmorillonite is one best-known examples, and octadecyltrimethylammonium (Mont-C18) results in adsorption anthracene pyrene together specific excimer emission, while nanostructure yet be uncovered at molecular level because gallery height only ca. 27 Å. We, herein, investigated this nanocomposite dynamics (MD)...
Non-equilibrium molecular dynamics (NEMD) simulations were employed to investigate the effect of charged pore-wall carbon nanotubes (CNTs), which is model microporous membranes. The study found that atoms on CNT significantly affect how water molecules orient themselves in pore through formation hydrogen bonds with atoms. Two different atomic charge arrangements investigated: a linear arrangement and double helix arrangement. latter resulted higher flux when tested at applied pressure....
In recent years，nicke1_metal hydride(MH) batteries have attracted great attention as clean， high capacity and long life secondary batteries，
The relation between the membrane structure and permeation property is technically important in development of forward osmosis (FO) membrane. We report herein on quantitative reproduction Lennard–Jones (LJ) -type fluid FO by nonequilibrium molecular dynamics (NEMD) using fluctuating-wall method. calculated through modeled was consistent with theoretical curve derived from combination flux Van’t Hoff equations, indicating that quantitatively reproduced. solvation effect also investigated...
