Polymer Research - Studies from NanJing University add new findings in the area of polymer research
2010 MAR 22 - (VerticalNews.com) -- According to a study from Nanjing, People's Republic of China, "Weakly emissive silicon nanoparticles with an average diameter of about 5 nm are prepared Via Pulsed laser ablation of silicon wafers in water. Electrostatic assembly of water-soluble conjugated polyelectrolytes on the Surface of the silicon nanoparticles steadily enhances the photoluminescence of these nanocomposites, indicating the possibility of energy transfer between the semiconductor nanoparticles and the conjugated polymer, or silicon nanoparticle-induced elimination of chain aggregates of the conjugated polyelectrolyte. ...read more
Polymer Research - Study results from State University of New York in the area of polymer research published
2010 MAR 22 - (VerticalNews.com) -- "The morphologies of multiblock copolymer melts (for simplicity, we consider tetra blocks) and their configurations when they are confined in cylindrical nanopores were examined by Lattice Monte Carlo simulations," investigators in the United States report. "The dependence of their morphologies and of the configurations of the copolymers (through the radius Of gyration) on the nanopore diameter, intersegment interaction energies (repulsive interaction energies between different kinds of segments of the copolymers), and attractive interactions between one kind of segments and the surface of the nanopore was investigated," wrote H.Y. Chen and colleagues, State University of New York ...read more
Polymer Research - Research from Anna University in the area of polymer research described
2010 MAR 22 - (VerticalNews.com) -- According to recent research from Madras, India, "Organophilic montmorillonite clay - unsaturated polyester (UP) and vinyl ester oligomer (VEO) - unsaturated polyester nanocomposites were prepared and the formation of nanocomposites was evaluated by X-ray diffraction (XRD), dynamic mechanical analysis (DMA) and scanning electron microscopy (SEM). The VEO was prepared by reacting commercially available epoxy resin LY556 and acrylic acid and was used as a toughening agent for unsaturated polyester resin. ...read more
