Biodegradable nano-composite polymer scaffolds for bone tissue engineering
Although hydroxyapatite (HA) ceramics has good osteoconductivity and osteoinductivity, the brittleness and fatigue failure in the body limit their clinical applications. Recent development of biodegradable polymers, mainly polyesters such as poly(L-lactic acid ) (PLLA), poly(glycolic acid) (PGA) and their copolymers (PLGA), is an attractive approach for tissue engineering with a wide rang...

[Macromol. Rapid Commun.] Polymer Brushes on Planar TiO2 Substrates
A facile and universal method is presented for the preparation of polymer brushes on amorphous TiO2 film. Homogeneous and stable poly(methyl methacrylate), polystyrene, poly(4-vinylpyridine), and poly(N-vinyl imidazole) (PNVI) brushes up to 550 nm are directly created onto TiO2 via UV-induced photopolymerization of corresponding monomers. Kinetic studies reveal a linear increase in thickness wit...

Hydrogenation of o-Chloronitrobenzene over Polymer-stabilized Palladium-Platinum Bimetallic Colloidal Clusters
Hydrogenation of o-chloronitrobenzene o-CNB. has been studied in methanol at 303 K and atmospheric pressure over polyvinylpyrrolidone-stabilized palladium–platinum PVP-PdrPt. bimetallic colloidal clusters. The catalytic properties for the hydrogenation of o-CNB to o-chloroaniline o-CAN. are found to depend on the metal composition of the bimetallic
clusters. All the bimetallic clusters are mor...

Synthesis of Monodisperse CdS/SiO2/Polymer Tri-layer Fluorescent Microspheres
Tri-layer CdS/SiO2/polymer hybrid nanospheres were synthesized by distillation precipitation polymerization of either ethyleneglycol dimethacrylate (EGDMA) or EGDMA together with comonomers having different functional groups, such as methacrylic acid, 4-vinylpyridine and 2-hydroxyethylmethacrylate, in the presence of 3-(methacryloxy)propyl trimethoxysilane (MPS)-modified CdS/SiO2 nanoparticles a...

The Magnetic Polymer Microsphere Stabilized Nano-Metallic Colloids as A Facilely Recoverable Catalyst
Magnetically responsive hierarchical magnetite/silica/poly(ethyleneglycol dimethacrylate-co-4-vinylpyridine) (Fe3O4/SiO2/P(EGDMA-co-VPy)) tri-layer microspheres were used as stabilizers for gold metallic nanocolloids as a facilely recoverable catalyst with the reduction of 4-nitrophenol to 4-aminophenol as a model reaction. The magnetic microsphere
stabilized gold metallic nanocolloids were prep...

Synthesis of Monodisperse Hollow Polymer Microspheres with Functional Groups by Distillation Precipitation Polymerization
Monodisperse hollow polymer microspheres having various functional groups on the shell-layer, such as carboxylic acid, pyridyl and amide, were prepared by two-stage distillation precipitation polymerization in neat acetonitrile in the absence of any stabilizer or additive, during which monodisperse poly(methacrylic acid) (PMAA) afforded from the
first-stage polymerization was utilized as the seeds...

Preparation of Narrow or Monodisperse Polymer Microspheres by Distillation-precipitation Polymerization
Narrow- or monodisperse poly(divinylbenzene-co-acrylonitrile) (poly(DVB-co-AN))
microspheres with reactive cyano group were prepared by distillation-precipitation
polymerization of divinylbenzene (DVB) and acrylonitrile (AN) in neat acetonitrile
with 2,2′-azobis(isobutyronitrile) (AIBN) as initiator in the absence of any stabilizer
or additive without stirring. The effects of the comonomer feed o...
