Nano- and microstructure of air/oil/water interfaces.
We report the creation of air/oil/water interfaces with variable-thickness oil films using polyisobutylene-based (PIB) surfactants cospread with long-chain paraffinic alkanes on clean water surfaces. The resultant stable oil layers are readily measurable with simple surface techniques, exhibit physical densities the same as expected for bulk oils, and are up to approximately 100 A thick above t...
متن کاملEnzymatic cross-linking at oil-water interfaces – a rheological study
Potential food-compatible technologies for novel oil-in-water emulsions include interfacial cross-linking by enzymatic means. The objective of the present research is to elucidate the mechanisms, by which protein interfaces control transfer of low molecular weight compounds. As a first step, the impact of enzymatic cross-linking on mechanical properties of -casein layer was studied. The depende...
متن کاملEllipsoidal Janus nanoparticles assembled at spherical oil/water interfaces.
The equilibrium behavior of ellipsoidal Janus nanoparticles adsorbed at spherical oil/water interfaces was investigated using dissipative particle dynamics simulations. Several phenomena were documented that were not observed on similar simulations for planar oil/water interfaces. The nanoparticles were found to yield isotropic, radial nematic phases, and axial nematic domains, depending on the...
متن کاملProbing diffusion of single nanoparticles at water-oil interfaces.
The diffusion of nanoparticles at a water-alkane interface is studied using fluorescence correlation spectroscopy. Hydrophilic and hydrophobic quantum dots of 5, 8, and 11 nm radius are used. A slow-down of nanoparticle diffusion at the liquid-liquid interface is observed. The effect is most evident when the viscosities of both liquid phases are similar, here, at the water-decane interface. In ...
متن کاملSelf-assembling of polymer-enzyme conjugates at oil/water interfaces.
Interface-binding enzymes are desirable for biphasic reactions in that they offer simultaneous access to substrates dissolved in both phases across the interface. It has been shown that conjugating water-soluble enzymes with hydrophobic polymers facilitated the assembling of enzymes at oil/water interfaces. In this work, the interfacial assembling of alpha-chymotrypsin conjugated with polystyre...
