Despite extensive research on the use of salts to enhance micellar growth, numerous questions remain regarding impact ionic exchange and molecular structure charge neutralization. This study looks into how certain cations (Na+, Ca2+, Mg2+) affect a cocamidopropyl betaine CAPB sodium dodecylbenzenesulfonate SDBS surfactant mixture, aiming toward applications in targeted delivery systems. The mixture consists zwitterionic surfactant, (CAPB), an anionic (SDBS), combined varying molar ratios at...
Complex fluids encompass a significant proportion of the materials we utilise today from feedstocks such as cellulose fibre dispersions, undergoing processing or formulation, through to consumer end products shampoo. Such systems exhibit intricate behaviour due their composition and microstructure, particularly when analysing texture (rheology) response flow. In particular, these flowing may undergo transitions in nano- potentially aligning with flow fields, breaking reassembling reforming,...
Wormlike micelles (WLMs) are vital components of many consumer products and industrial fluids, adding a shear-dependent viscous texture through their entanglement in solutions. It is now well accepted from experiments such as coupling rheology scattering that, similar to polymer solutions dispersions highly anisotropic particles, WLM behavior during shear arises the alignment “worms” with field, resulting ordering that rapidly lost cessation shear. Most studies systems have been limited...
Hypothesis The behaviour of surfactants in solution and at interfaces is governed by a combination steric electrostatic effects experienced surfactant molecules as they interact with solvent, other species solution, each other. It would therefore be anticipated that highly interacting groups significantly influence behaviour. widely used amide functionality has polar H-bond donor/acceptor properties, its inclusion into structure should have profound effect on surface activity self-assembly...
The self-assembly of long tail sugar-based surfactants into worm-like micelles has recently been demonstrated, and the rheological properties such systems have shown to be tuneable through subtle modifications molecular characteristics surfactant monomer. In particular, anomeric configuration hexadecylmaltoside headgroup was induce profound changes in nanostructure rheology system. origin is hypothesised arise from differences structure relaxation micellar networks semi-dilute regime.Here we...
Concentrated wormlike micellar fluids form the basis for a vast array of formulated products, from liquid soaps and shampoos to drag reduction drilling fluids. Typically, these systems are analyzed using bulk rheological measurements determine their flow properties cryo-microscopy detect nanostructure. Small-angle neutron scattering provides an opportunity directly nonperturbatively analyze nanostructure in situ but is complicated concentrated by correlations interparticle volume exclusion....
Ether-linked surfactants are widely used in formulations such as liquid soaps, but despite their ubiquity, it is unclear how
Abstract Utilizing cell membranes from diverse types for biointerfacing has demonstrated significant advantages in enhancing colloidal stability and incorporating biological properties, tailored specifically various biomedical applications. However, the structures of these materials, particularly emulsions interfaced with red blood (RBC) or platelet (PLT) membranes, remain an underexplored area. This study systematically employs small‐ ultra‐small‐angle neutron scattering (SANS USANS)...
Surfactants provide detergency, foaming, and texture in personal care formulations, yet the micellization of typical industrial primary cosurfactants is not well understood, particularly light polydisperse nature commercial surfactants. Synergistic interactions are hypothesized to drive formation elongated wormlike self-assemblies these mixed surfactant systems. Small-angle neutron scattering, rheology, pendant drop tensiometry used examine surface adsorption, viscoelasticity, self-assembly...
