Effect of internal phase contents on porous polymers prepared by a high internal phase emulsion methods.
A series of porous polymers
poly(styrene-divinylbenzene) was synthesized by the polymerization of 9 : 1 (v/v)
styrene/divinylbenzene using high-internal-phase emulsions (HIPEs) as template,
cetyltrimethyl ammonium bromide as a surfactant in the presence of
water-miscible organic additives ethanol, with internal-phase contents varied
from 82.5 to 94.0%. The effects of the internal-phase contents ...

Fabrication of highly dispersed ZnO nanoparticles embedded in graphene nanosheets for high performance supercapacitors
We report a facile strategy to synthesize ZnO-graphene nanocomposites as an advanced electrode material for high-performance supercapacitors. The ZnO-graphene nanocomposites have been fabricated via a facile, low-temperature in situ wet chemistry process. During this process, high dispersed ZnO nanoparticles are embedded in graphene nanosheets, leading to sandwich-structured ZnO-graphene nanocom...

Synthesis and Characterization of Comb and Centipede Multigraft Copolymers PnBA-g-PS with High Molecular Weight Using Miniemulsion Polymerization
Comb and centipede multigraft copolymers, poly(n-butyl acrylate)-g-polystyrene (PnBA-g-PS) with PnBA backbones and PS side chains, were synthesized via high-vacuum anionic polymerization and miniemulsion polymerization. Single-tailed and double-tailed PS macromonomers were synthesized by anionic polymerization and Steglich esterification. Subsequently, the copolymerization of each macromonomer a...

Double-shelled Hollow SnO2/Poymer Microsphere as A High-capacity Anode Material for Superior Reversible Lithium Ion Storage
Double-shelled hollow tin
dioxide/poly(ethyleneglycol dimethacrylate- co-methacrylic
acid) (SnO2/P(EGDMA-co-MAA))
microspheres were prepared by selective removal of silica inner core via
etching with hydrofluoric acid from the corresponding SiO2/SnO2/P(EGDMA-co-MAA) tri-layer microspheres. These
tri-layer microspheres were synthesized by combination of modified St?ber
method for silica inner core,...

MacromolRapidCommun--Tellurium-based polymeric surfactants as a novel seleno-enzyme model with high activity
A tellurium-based polymeric sufactant as a seleno-enzyme model has been constructed by employing 11-acryloyloxyundecyltriethylammonium bromide (AUTEAB, 4) and a tellurium-containing compound (1). It demonstrates strong substrate binding ability for thiols and high glutathione peroxidase (GPx) activity about 6 orders of magnitude more efficient than the well-known GPx mimic PhSeSePh in an ArSH assa...

JInclPhenomMacro--A glutathione peroxidase mimic 6,6 ''-ditellurobis (6-deoxy-beta-cyclodextrin) with high substrate specificity
Glutathione peroxidase (GPx) is one of the most
important antioxidative selenoenzymes in living organisms. The novel GPx mimic 6,6’-ditellurobis(6-deoxy-b-cyclodextrin) (6-TeCD) was prepared and evaluated for
its capacity to catalyze the reduction of H2O2, tert-butyl hydroperoxide (t-BuOOH), and cumene hydroperoxide (CuOOH) by
glutathione (GSH) or 3-carboxy-4-nitrobenzenethiol (ArSH). Compared th...

MacromolBiosci--A Dual Enzyme Microgel with High Antioxidant Ability Based on Engineered Seleno-Ferritin and Artificial Superoxide Dismutase
An antioxidant microgel with both glutathione peroxidase (GPx) and superoxide dismutase (SOD) activities is reported. Using computational design and genetic engineering methods, the main catalytic components of GPx are fabricated onto the surface of ferritin. The resulting seleno-ferritin (Se-Fn) monomers can self-assemble into nanocomposites that exhibit remarkable GPx activity due to the well or...

ChemEurJ--Cyclodextrin-derived mimic of glutathione peroxidase exhibiting enzymatic specificity and high catalytic efficiency
To elucidate the relationships between molecular recognition and catalytic ability, we chose three assay systems using three different thiol substrates, glutathione (GSH), 3-carboxyl-4-nitrobenzenethiol (CNBSH), and 4-nitrobenzenethiol (NBSH), to investigate the glutathione peroxidase (GPx) activities of 2,2′-ditellurobis(2-deoxy-β-cyclodextrin) (2-TeCD) in the presence of a variety of structura...

A facile route to the synthesis of spherical poly(acrylic acid) brushes via RAFT polymerization for high-capacity protein immobilization
Spherical poly(acrylic acid) brushes were prepared via a facile RAFT polymerization route from silica nanoparticles (SiO2@PAAs). A silane functionalized RAFT chain transfer agent was designed and synthesized by a one-step reaction, and then immobilized onto silica nanoparticles (SiNPs) through its R group to afford RAFT polymerization. Key structural parameters and contents of carboxyl groups of...
