We use molecular dynamics to study the nucleation of AgBr in water. After first testing our Born–Mayer–Huggins potentials for Ag+ and Br− by looking at bulk AgBr and at AgBr clusters in vacuo, we consider small numbers of Ag+ and Br− ions imm

We report adhesion studies using the JKR contact mechanics method and poly(dimethylsiloxane) (PDMS) cross-linked networks. When such networks are extracted, interdigitation of tethered chains into extraction zones at the network-network interface res

The preparation, structure, properties and applications of self-assembled monolayers (SAMs) of rigid 4-mercaptobiphenyls are briefly reviewed. The rigid character of the biphenyl moiety results in a molecular dipole moment that affects both the adsor

Adhesion is one of the most ubiquitous phenomena in nature that governs many practical processes. It is a complex, multifaceted phenomenon that involves factors such as surface chemistry and thermodynamics, polymer chemistry and physics, hydrodynamic

The structure of a colloidal suspension under shear flow was studied by in situ small angle neutron scattering (SANS). This suspension exhibited shear thinning at low shear rates and shear thickening at high shear rates. Under quiescent conditions, t

Mixed monolayers of CH3/OH‐terminated alkanethiolates chemisorbed on gold exhibit anomalous variations of wettabilities, possibly because of adsorption of a minority species from the bulk. Starting from a lattice‐gas model with proper quenched av

We performed ab initio geometry optimization of HS and CH 3 S on cluster models of Au(111), Au(100), Ag(111), and Ag(100) surfaces, at the RECP Hartree-Fock+electron correlation (MBPT2) level. From these we determined classical force field parameters

We introduce a method of generating systematic mean field (MF) approximations for the nonequilibrium steady state of ferromagnetic Ising driven diffusive systems (DDS), based on the maximum entropy principle due to Jaynes. In the phase coexistence re

Studies of wetting and stability of mixed monolayers containing hydrophobie and hydrophilic components are discussed. We are reporting the observation of an apparent concentration-driven transition in the cosine of the contact angles of liquids on mi

The construction of mixed monolayers containing hydrophobic and hydrophilic components for which the contact angles for three different liquids vary as a highly nonlinear function of the monolayer composition is reported. It is suggested that a prewe
