Solvation Force in Hard Ellipsoid Molecular Liquids with Rod-Sphere and Rod- Surface Interactions
In previous work, one of us calculated the Solvation force of hard ellipsoid fluid with hard Gaussian overlap potential using hard needle wall interaction and non-linear equation proposed by Grimson- Rickyazen. In present work, using density functional theory and extended restricted orientation model, the solvation force of hard ellipsoid fluid in presence of more realistic rod- sphere and rod-...
متن کاملManipulation of molecular transport into mesoporous silica thin films by the infiltration of polyelectrolytes.
The design of hybrid mesoporous materials incorporating polymeric assemblies as versatile functional units has become a very fertile research area offering major opportunities for controlling molecular transport through interfaces. However, the creation of such functional materials depends critically on our ability to assemble polymeric units in a predictable manner within mesopores with dimens...
متن کاملMolecular dynamics simulations of multilayer polyelectrolyte films: effect of electrostatic and short-range interactions.
The effect of the strength of electrostatic and short-range interactions on the multilayer assembly of oppositely charged polyelectrolytes at a charged substrate was studied by molecular dynamics simulations. The multilayer buildup was achieved through sequential adsorption of charged polymers in a layer-by-layer fashion from dilute polyelectrolyte solutions. The strong electrostatic attraction...
متن کاملPolyelectrolyte-quantum dot multilayer films fabricated by combined layer-by-layer assembly and Langmuir-Schaefer deposition.
Stable multilayer thin films, assembled by a combination of layer-by-layer processing of polyelectrolytes and inorganic quantum dot monolayers prepared using the Langmuir-Schaefer deposition procedure, have been examined. Film formation and structure are confirmed using UV-vis absorption measurements and fluorescence spectroscopy. Growth is shown to be linear over several polyelectrolyte-quantu...
متن کاملMultilayers of Low Charge Density Polyelectrolytes on Thin Films of Carboxymethylated and Cationic Cellulose
Multilayers with low charge density polyelectrolytes assembled on thin films of cellulose were studied by piezoelectric microgravimetry. The substrates were produced from colloidal suspensions of cotton fibers before and after modification with cationic and anionic groups via epoxy intermediates of quaternary ammonium and carboxymethylation, respectively. Two different levels of ionicity were u...
