The pair correlation function of charge stabilized colloidal particles under strongly sheared conditions is studied using the analytical intermediate asymptotics method recently developed in Banetta and Zaccone (Phys. Rev. E 99, 052606 (2019) to solve the steady-state Smoluchowski equation for medium to high values of the Péclet number; the analyti...

Thermosensitive star-shaped eight-arm poly-2-alkyl-2-oxazolines (M = 21,000 g mol−1) was synthesized. The arms were gradient copolymers of 2-ethyl-2-oxazoline (EtOx) and 2-isopropyl-2-oxazoline (iPrOx). The more hydrophilic EtOx units prevailed near the calix[8]arene core. For comparison, model linear gradient copolymer (M = 3800 g mol−1) was inves...

While similar in nature, the properties of silica and silsesquioxane are very different, but little is known about these differences. In this paper, functionalized silsesquioxane microparticles are synthesized by adapting the modified Stöber method and post-functionalized with rhodamine B. The as-synthesized silsesquioxane particles are characteriz...

The magnetic properties of nanoparticles make them ideal for use in various applications, especially in biomedical applications. Herein, we describe the fabrication of iron oxide nanoparticles encapsulated in polystyrene (PS) using two methods: a conventional batch and microfluidic synthesis. In particular, we present a simple synthesis method of m...

Magnetic reduced graphene oxide/polymer nanocomposites were prepared by in situ polymerization and grafting of polyacrylamide on the surface of functionalized magnetic reduced graphene oxide (rGO). Graphene oxide nanosheets were decorated with Fe3O4 nanoparticles, reduced and functionalized with 3-(trimethoxysilyl)propyl methacrylate, and then graf...

This study aimed to clarify the effects of different types of nano-SiO2 and surfactants on the oil-water IFT and IFR. These interfacial properties were demonstrated to be influenced by the interaction between the surfactant, the nano-SiO2 and the oil component. The interaction between nano-SiO2 and oil components and their adsorption at the crude o...

The use of methoxy polyethylene glycol thiol (mPEG-SH), in conjunction with additives, is one of the most straightforward, versatile, and widely used methods for modifying gold nanorods (GNRs), especially for applications in the field of biomedicines. The decreased toxicity of PEGylated GNRs is critical for investigating cell-nanomaterial interacti...

Taking the positive charged poly (diallyldimethylammonium chloride), PDDA, and negative charged polymaleic acid, PMA, as raw materials, the polyelectrolyte multilayer film, PMF, with oppositely charged surfaces was prepared by the layer-by-layer electric-assembly, LBLEA, method. Experimentally, the applied voltage was varied and the electrostatic f...

A new diurea-type gelator was synthesized from 2-isocyanoethyl acrylate and 4′-diaminodiphenylmethane, which formed supramolecular gel in acetonitrile driven by hydrogen bonds. The xerogel fibers with a smooth lamellar structure were used as templates and monomer source in fabricating polymer microtubes via reversible addition-fragmentation chain t...

A Cu-free clickable polymer was synthesized and used to dip-coat plastic substrates to prepare Cu-free clickable surfaces. The surface density of dibenzocyclooctyne moieties was quantified using an azide-conjugated fluorophore and a conventional fluorometer, indicating that the clickable moieties displayed on a dip-coated surface were accessible fr...
