Surface structure of sodium dodecyl sulfate surfactant and oil at the oil-in-water droplet liquid/liquid interface: a manifestation of a nonequilibrium surface state

We present sum frequency scattering spectra on kinetically stabilized emulsions consisting of nanoscopic oil droplets in water, stabilized with sodium dodecyl sulfate (SDS). We have measured the interfacial structure of the alkyl chains of the surfactant m ...

Use of Simple Kinetic and Reaction-Order Measurements for the Evaluation of the Mechanism of Surfactant-Liposome Interactions

Surfactant liposome interactions have been previously studied through different methods and techniques. We present here a classical physical chemistry study on liposome solutions added to destabilizing agents at concentrations well above the solubilization ...

Characterization of cationic liposomes. Influence of the bilayer composition on the kinetics of the liposome breakdown

The cationic large unilamellar mixed liposomes from 1-palmitoyl-2-oleoyl-phosphatidylcholine (POPC) and didodecyldimethylammonium bromide (DDAB) or dioctadecyldimethylammonium bromide (DODAB) were prepared. The influence of the addition of Triton X-100 (TX ...

Exotic droplets formed in microfluidic chips with uniform wettability

Martinus Gijs, Virendra Kumar Parashar, Josias Basil Wacker, Cédric Razaname, Guillaume Louis

Microdroplets are widely used in industrial processes. In the absence of external forces, droplets generally assume a spherical shape. Here, we present two methods to form non-spherical droplets in microfluidic glass chips. A uniformly hydrophobized chip h ...

Synchrotron microangiography studies of angiogenesis in mice with microemulsions and gold nanoparticles

Giorgio Margaritondo, Chao Wang

We present an effective solution for the problem of contrast enhancement in phase-contrast microangiography, with the specific objective of visualising small (< 8 A mu m) vessels in tumor-related microangiogenesis. Different hydrophilic and hydrophobic con ...

Influence of emulsion composition on lubrication capacity and texture perception

Stefano Mischler

P>The role of fat content and type of surfactant for oral friction processes and texture perception of oil-in-water emulsions was assessed. Emulsions at 22% and 33% fat content containing either sodium caseinate or a sucrose ester as emulsifier were compar ...

Influence of Oil Type and Viscosity on Droplet Size in a Flow Focusing Microfluidic Device

Martinus Gijs, Virendra Kumar Parashar, Josias Basil Wacker

We form water-in-oil droplets in a microfluidic channel-nozzle geometry for studying the influence of viscosity of oil and of different oil classes on the droplet size. We find that the chemical structure of oil dominates over its viscosity. Our studies ar ...

Sorption of hydrophobic organic compounds (HOC) in rapeseed oil bodies

Ian William Marison, Julien Boucher

Oil-bodies are minute plant organelles (0.5-2.0 mu m diameter) consisting of an oil core surrounded by a phospholipid monolayer/proteinaceous membrane. Oil-bodies have been isolated from rapeseed seeds and demonstrated to constitute a novel type of micro-c ...

Breakdown kinetics of aggregates from poly(ethylene glycol-bl-propylene sulfide) di- and triblock copolymers induced by a non-ionic surfactant

Jeffrey Alan Hubbell

We explored the effects of addition of the nonionic surfactant Triton X-100 on the stability of aggregates of poly(ethylene glycol-bl-propylene sulfide) di- and triblock copolymers. Fluorescence spectra of pyrene, used as a probe molecule, elucidated the v ...

Microemulsion-synthesized Pt/Ru/Sn nanoparticles on BDD for alcohol electrooxidation

Christos Comninellis, György Foti, Guillaume Siné, Mériadec Limat

Ternary Pt-based nanoparticles (nominal composition Pt80Ru10Sn10 ) were synthesized via the microemulsion route and deposited onto boron-doped diamond (BDD) electrode. The particle size measured by transmission electron microscopy was in the 2–5nm diam ran ...
