Gelation and Re-entrance in Mixtures of Soft Colloids and Linear Polymers of Equal Size
D. Parisi, D. Truzzolillo, A. H. Slim +6
Liquid mixtures composed of colloidal particles and much smaller non-adsorbing linear homopolymers can undergo a gelation transition due to polymer-mediated depletion forces. We no…
Bacterial Motility Enhances Adhesion to Oil Droplets
Narendra K. Dewangan, Jacinta C. Conrad
Adhesion of bacteria to liquid-liquid interfaces can play a role in the biodegradation of dispersed hydrocarbons and in biochemical and bioprocess engineering. Whereas thermodynami…
Soft interactions modify the diffusive dynamics of polymer-grafted nanoparticles in solutions of free polymer
Ryan Poling-Skutvik, Ali H. Slim, Suresh Narayanan +2
We examine the dynamics of silica particles grafted with high molecular weight polystyrene suspended in semidilute solutions of chemically similar linear polymer using x-ray photon…
Tunable Assembly of Gold Nanorods in Polymer Solutions to Generate Controlled Nanostructured Materials
Ryan Poling-Skutvik, Jonghun Lee, Suresh Narayanan +2
Gold nanorods grafted with short chain polymers are assembled into controlled open structures using polymer-induced depletion interactions and structurally characterized using smal…
Coupling of nanoparticle dynamics to polymer center-of-mass motion in semidilute polymer solutions
Renjie Chen, Ryan Poling-Skutvik, Arash Nikoubashman +3
We investigate the dynamics of nanoparticles in semidilute polymer solutions when the nanoparticles are comparably sized to the polymer coils using explicit- and implicit-solvent s…
Glasslike Arrest in Spinodal Decomposition as a Route to Colloidal Gelation
S. Manley, H. M. Wyss, K. Miyazaki +5
Colloid-polymer mixtures can undergo spinodal decomposition into colloid-rich and colloid-poor regions. Gelation results when interconnected colloid-rich regions solidify. We show…
