Capillary wave spectrum at adsorbed liquid films

Interaction of magnetic nanoparticles with phospholipid films adsorbed at a liquid/liquid interface.

The interaction of Co hexagonal magnetic nanoparticles (MNPs) with distearoyl phosphatidyl glycerol (DSPG) and distearoyl phosphatidic acid (DSPA) films adsorbed at a water/1,2-dichloroethane interface is studied employing cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), capacity curves and interfacial pressure-area isotherms. DSPA and DSPG adsorb at the interface forming ...

Molecular-Dynamics Simulations of Adsorbed Ionic-Liquid Films

Temperature-reversible ultrathin films of N-isopropylacrylamide terpolymer adsorbed at the solid-liquid interface.

This article describes the stability and reversibility of ultrathin films of N-isopropylacrylamide (NIPA)-vinylimidazole (VI)-poly(ethylene glycol) (PEG) graft terpolymer adsorbed at the solid-liquid interface upon temperature cycling from below to above its phase transition temperature. The coil-to-globule and globule-to-coil phase transitions were captured by in situ fluid tapping atomic forc...

Capillary models for liquid crystal fibers, membranes, films, and drops

This paper presents an overview of the capillary modeling science of nematic liquid crystals and its applications to the stability, structure, and shape of films, membranes, fibers, and drops. Liquid crystals are anisotropic viscoelastic materials possessing long range orientational order, and hence these models are relevant to the capillary science of anisotropic soft matter. A systematic mult...

Thermal capillary waves relaxing on atomically thin liquid films

Atomistic simulations are used to investigate the relaxation dynamics of thermal capillary waves on thin flat liquid films. Short Lennard-Jones polymers n=2, 4, and 8 model the liquid in films of thickness 6 to 96 , where is the Lennard-Jones atomic length-scale parameter. Assuming no-slip boundary conditions on the solid wall and constant surface tension and viscosity, the standard continuum m...
