Activated complex model and surfactant reorganization during SWCNT separations on hydrogels

Submersion and lateral transport behavior of microparticles at a lung surfactant interface on model mucus hydrogels

A Mathematical Model for Adsorption of Surfactant onto Powdered Activated Carbon

The main objectives of this study were to remove surface-active agents and to predict the adsorption rejection models.  The effects of surfactant concentration and PAC amount on the adsorption were determined. For both surfactants, It was found that the adsorption values also increased when PAC amount increased. It was observed that the rejection values are different for the adsorption of C...

Reorganization of cytoskeleton during surfactant secretion in lung type II cells: a role of annexin II.

The secretion of lung surfactant requires the movement of lamellar bodies to the plasma membrane through cytoskeletal barrier at the cell cortex. We hypothesized that the cortical cytoskeleton undergoes a transient disassembly/reassembly in the stimulated type II cells, therefore allowing lamellar bodies access to the plasma membrane. Stabilization of cytoskeleton with Jasplakinolinde (JAS), a ...

Surfactant micelles: model systems for flow instabilities of complex fluids.

Complex fluids such as emulsions, colloidal gels, polymer or surfactant solutions are all characterized by the existence of a "microstructure" which may couple to an external flow on time scales that are easily probed in experiments. Such a coupling between flow and microstructure usually leads to instabilities under relatively weak shear flows that correspond to vanishingly small Reynolds numb...

Chapter Six Surfactant induced softening in gelatin hydrogels

6.1 Abstract Effect of binding of three surfactants, alpha olefin sulfonate (AOS, anionic), TritonXIOO (TX-100, non-ionic) and cetyl trimethyl ammonium bromide (CTAB, cationic) to the hydrogels of gelatin was studied at room temperature (25°C) by dynamic light scattering and oscillatory rheology with surfactant concentrations (20-1 OOmM) much larger than the critical micellar concentrations (er...
