Interfacial assembly of lipopeptide surfactants on octyltrimethoxysilane-modified silica surface.
The adsorption of a series of cationic lipopeptide surfactants, C14Kn (where C14 denotes the myristic acyl chain and Kn represents n number of lysine residues) at the hydrophobic solid/water interface has been studied using spectroscopic ellipsometry (SE) and neutron reflection (NR). The hydrophobic C8 surface was prepared by grafting a monolayer of octyltrimethoxysilane on the silicon surface....
متن کاملInfluences of surfactant and nanoparticle assembly on effective interfacial tensions.
We have studied assembly at air-water and liquid-liquid interfaces with an emphasis on systems containing both surfactants and nanoparticles. Anionic surfactants, sodium dodecyl sulfate (SDS) and non-ionic surfactants, Triton X-100 and tetraethylene glycol alkyl ethers (C(8)E(4), C(12)E(4) and C(14)E(4)), effectively decrease the surface tension of air-water interfaces. The inclusion of negativ...
متن کاملInterfacial behavior of catanionic surfactants.
We report a dramatic increase in foam stability for catanionic mixtures (myristic acid and cetyl trimethylammonium bromide, CTABr) with respect to that of CTABr solutions. This increase was related to the low surface tension, high surface concentration, and high viscoelastic compression moduli, as measured with rising bubble experiments and ellipsometry. Dialysis of the catanionic mixtures has ...
متن کاملBolaform surfactants with polyoxometalate head groups and their assembly into ultra-small monolayer membrane vesicles
Surfactants are indispensable in established technologies as detergents or emulsification agents, and also in recent studies for controlling the growth of nanoparticles or for creating nanocarriers. Although the properties of conventional, organic surfactants are thoroughly explored, strong interest persists in surfactants that possess unique features inaccessible for ordinary systems. Here we ...
متن کاملInterfacial Properties of Sugar-based Surfactants
Motivation Interest is growing in the development of material technologies that are based on renewable resources. The use of biomass as feedstock is of expanding industrial significance, particularly in the energy and commodities sectors. Relative to these arenas, monoand polysaccharides, very flexible and tunable chemical starting materials, are estimated to make up three-quarters of the world...
