Hydrophobic Interactions and Dewetting between Plates with Hydrophobic and Hydrophilic Domains
We study by molecular dynamics simulations the wetting/dewetting transition and the dependence of the free energy on distance between plates that contain both hydrophobic and hydrophilic particles. We show that dewetting and strength of hydrophobic interaction is very sensitive to the distribution of hydrophobic and hydrophilic domains. In particular, we find that plates characterized by a larg...
متن کاملHydrophobic and hydrophilic interactions in aqueous mixtures of alcohols at a hydrophobic surface.
Aqueous solutions of alcohols are interesting because of their anomalous behavior that is believed to be due to the molecular structuring of water and alcohol around each other in solution. The interfacial structuring and properties are significant for application in alcohol purification processes and biomolecular structure. Here we study aqueous mixtures of short alcohols (methanol, ethanol, 1...
متن کاملRandom hydrophilic-hydrophobic copolymers
We study a single statistical amphiphilic copolymer chain AB in a selective solvent (e.g. water). Two situations are considered. In the annealed case, hydrophilic (A) and hydrophobic (B) monomers are at local chemical equilibrium and both the fraction of A monomers and their location along the chain can vary, whereas in the quenched case (which is relevant to proteins), the chemical sequence al...
متن کاملFibronectin Adsorption on Hydrophilic and Hydrophobic Surfaces
Studies have been carried out on the adsorption properties of plasma fibronectin (FN) on hydrophobic and hydrophilic surfaces. The hydrophobic and hydrophilic surfaces used were nonwettable bacteriological dishes and wettable tissue culture dishes, respectively. At low plasma FN concentrations, there was more plasma FN binding to hydrophobic surfaces than to hydrophilic surfaces. Under these co...
متن کاملThermal conductance of hydrophilic and hydrophobic interfaces.
Using time-domain thermoreflectance, we have measured the transport of thermally excited vibrational energy across planar interfaces between water and solids that have been chemically functionalized with a self-assembled monolayer (SAM). The Kapitza length--i.e., the thermal conductivity of water divided by the thermal conductance per unit area of the interface--is analogous to the "slip length...
