Kinetics of Surfactant Adsorption at Fluid/Fluid Interfaces: Non-ionic Surfactants [PDF]
Europhysics Letters (EPL), 1998 We present a model treating the kinetics of adsorption of soluble surface-active molecules at the interface between an aqueous solution and another fluid phase.

A Surfactant Enables Efficient Membrane Spanning by Non-Aggregating DNA-Based Ion Channels
Molecules, 2022 DNA nanotechnology makes use of hydrophobically modified constructs to create synthetic membrane protein mimics. However, nucleic acid structures exhibit poor insertion efficiency, leading to a low activity of membrane-spanning DNA protein mimics.

Chemical and Biological Technologies in Agriculture, 2023 Background Surfactants are added to spray solutions because they significantly improve foliar uptake of active ingredients (AIs) into the leaves. It was intended to investigate whether surfactant solutions forming a dried deposit on Prunus leaf surfaces ...

Synergistic wetting effect of composite surfactant on hydrophobic coal
Meikuang Anquan, 2023 To improve the dust reduction efficiency of coal seam water injection, two kinds of non-ionic and two kinds of anionic surfactants were selected to study the surface tension and wetting characteristics of monomer and composite surfactant solutions.

Kinetics of non-ionic surfactant adsorption at a fluid-fluid interface from a micellar solution [PDF]
, 2005 The kinetics of non-ionic surfactant adsorption at a fluid-fluid interface from a micellar solution is considered theoretically. Our model takes into account the effect of micelle relaxation on the diffusion of the free surfactant molecules.

Polyhedral Non-ionic Surfactant Vesicles
Journal of Pharmacy and Pharmacology, 1997 Abstract Large polyhedral (2–10 μm) non-ionic surfactant vesicles (niosomes) formed from mixtures of a hexadecyl diglycerol ether (C16G2), a cholesteryl poly-24-oxyethylene ether (solulan C24) and a low level of cholesterol are being investigated as slow-release systems for ophthalmic, subcutaneous or intramuscular administration.

Double-walled carbon nanotube dispersion via surfactant substitution [PDF]
, 2009 A new approach for the stabilisation of double-walled carbon nanotubes in aqueous media was developed. A low molecular weight surfactant was used in the first stage for the debundling of the nanotubes followed by substitution with a higher molecular ...

Removal of chromium (III) by two-aqueous phases extraction [PDF]
, 2009 Two-aqueous phase extraction of chromium (III) as a solute from their aqueous solutions was investigated using polyethoxylated alcohols (CiEj) as a biodegradable non-ionic surfactant in the presence of anionic sodium dodecylbenzene sulfonate (SDBS ...
