[J. Am. Ceram. Soc.] Polymer-Derived Ceramic Microspheres with Controlled Morphology via Novel Phase-Separation Assisted Pyrolysis
Abstract: In this contribution, a novel and versatile
strategy named phase-separation assisted pyrolysis for the preparation of
polymer-derived ceramic microspheres with controlled morphology is reported. Various Si-C-N-(Ni) magnetic
microspheres with a dimension from micro to nano scale can be conveniently prepared by
using polymeric precursor with an assistance of polymer template of linear po...

β-Lactoglobulin (BLG) binding to highly charged cationic polymer-grafted magnetic nanoparticles: Effect of ionic strength
Poly(2-(methacryloyloxy)ethyltrimethyl ammonium chloride) (PMATAC) modified magnetic nanoparticles (NPs) with a high zeta potential of ca. 50 mV were synthesized by atom transfer radical polymerization (ATRP). The prepared NPs consist of a magnetic core around 13 nm and a PMATAC shell around 20 nm attached on the surface of magnetic nanoparticles. Thermodynamic binding parameters between β-lactog...

[Chem. Commun] Reversible morphology transitions of supramolecular polymer self-assemblies for switch-controlled drug release
A novel method for switch-controlled drug release was developed through the reversible morphology transitions of supramolecular branched copolymer self-assemblies. The reversible transitions from vesicles to nanoparticles were successfully achieved by alternating UV and visible light irradiation to obtain morphology-controlled drug release in a switch mode.
In this st...

Equal Low-Order Finite Element Simulation of the Planar Contraction Flow for Branched Polymer Melts
The rheological characteristics of branched polymer melts
is described by the modified XPP model, which is discretized by
inconsistent streamline-upwind method. A finite increment calculus
procedure is introduced to reformulate the mass equation and to
overcome oscillations of the pressure field. Moreover, the governing
equations are discretized and solved by the iterative fractional step
algorith...

Catechol-functionalized microporous organic polymer as supported media for Pd nanoparticles and its high catalytic activity
We report a new hydroxyl functionalized microporous organic polymer (MOPOH) based on the polymerization of catechol with terephthalaldehyde using phenolic resin-inspired chemistry. This catechol-decorated material, with surface area of 874 m2 g?1 and micro, mesopores, facilitates the immobilization and dispersion of Pd nanoparticles (NPs) on the polymer matrix. The surface area of t...

[Polym. Chem.] Wafer-scale Synthesis of Defined Polymer Brushes under Ambient Conditions
A method is presented that allows for the first time the preparation of highly defined polymer brush coatings on the wafer-scale under ambient conditions (room temperature, exposure to air) from a broad variety of monomers. The discovered high oxygen-tolerance of the surface-initiated Cu(0)-mediated controlled radical polymerization (SI-CuCRP) yields entire wafers homogeneously covered by a polyme...

Novel sulfonated polyimide/zwitterionic polymer-functionalized graphene oxide hybrid membranes for vanadium redox flow battery
Hybrid membranes (SPI/ZGO) composed of sulfonated polyimide (SPI) and zwitterionic polymer-functionalized graphene oxide (ZGO) are fabricated via a solution-casting method for vanadium redox flow battery (VRB). Successful preparation of ZGO fillers and SPI/ZGO hybrid membranes are demonstrated by FT-IR, XPS and SEM, indicating that ZGO fillers is homogeneously dispersed into SPI matrix. Through co...
