From beads-on-a-string to colloidal aggregation: novel crystallization phenomena in the PEO-SDS system
(1999)The anionic surfactant sodium dodecyl sulfate (SDS) interacts strongly with poly(ethylene oxide) (PEO) in aqueous solution, forming micellar aggregates attached to the polymer chains above the so-called critical association ...

Gold colloids from cationic surfactant solutions. 1. Mechanisms that control particle morphology
(2002)The mechanism of formation of gold particles by reduction of AuIII in solutions of alcyltrimethylammonium chloride surfactants was studied in the absence and in the presence of NaCl. AuIII anions interact strongly with ...

Article
On the modeling of semisolid suspensions
(2008)Due to the distinct rheology of semisolid slurries the process has well established advantages over competing near-net-shape manufacturing technologies. Despite the obvious advantages of the process its adoption by the ...

Poly(ethylene glycol)-based amphiphilic model conetworks: Synthesis by RAFT polymerization and characterization
(2008)Polyethylene glycol) (PEG)-containing quasi-model amphiphilic polymer conetworks (APCNs) were prepared by reversible addition fragmentation chain transfer (RAFT) polymerization using α,ω-bis(2-cyanoprop-2-yl dithiobenzoate)-PEG ...

Predictions of structure breakdown, buildup and shear banding in semisolid suspensions
(2008)When SSM material is subjected to a sudden transient the rate of buildup (aging) is negligible compared to the rate of breakdown (shear rejuvenation). While this is generally true, due to prolonged processing or the geometry ...

Thixotropic flow past a cylinder
(2014)We study the flow of a thixotropic fluid around a cylinder. The rheology of the fluid is described by means of a structural viscoplastic model based on the Bingham constitutive equation, regularised using the Papanastasiou ...
