Принадлежит: Arizona Board of Regents of University of Arizona

Methods are disclosed for synthesizing nanocomposite materials including ferromagnetic nanoparticles with polymer shells formed by controlled surface polymerization. The polymer shells prevent the nanoparticles from forming agglomerates and preserve the size dispersion of the nanoparticles. The nanocomposite particles can be further networked in suitable polymer hosts to tune mechanical, optical, and thermal properties of the final composite polymer system. An exemplary method includes forming a polymer shell on a nanoparticle surface by adding molecules of at least one monomer and optionally of at least one tethering agent to the nanoparticles, and then exposing to electromagnetic radiation at a wavelength selected to induce bonding between the nanoparticle and the molecules, to form a polymer shell bonded to the particle and optionally to a polymer host matrix. The nanocomposite materials can be used in various magneto-optic applications.

The MIPs are capable of binding to all or a portion of a specific target macromolecule associated with a disease located within the living body and they are derivatized for stealth for in vivo applications to avoid the reticuloendothelial system. The MIPs of the invention are functionalized to an amine or carboxyl group and are derivatized with an imaging and/or therapeutic agent for taking images of the disease and/or for providing therapy. The macromolecule can be selected from a group consisting of proteins, glycoproteins, lipoproteins, peptidoglycans, peptides, polypeptides, polynucleotides, and polysaccharides. The invention described herein also provides methods and kits wherein MIPs of the invention can be employed as targeted imaging and therapeutic agents.

Pectinases, such as Pectinex™ Ultra SP-L (composed of the enzyme Polygatacturonase, a type of pectinase which is derived from Aspergillus aculeatus ) or pectinmethylesterases were used to decrease or increase, respectively, the viscosity of fiber solutions, especially solutions with highly refined cellulosic thickeners, and particularly those made of highly refined cellulosic parenchyma cell wall fiber solutions. The enzyme can reduce the viscosity up to 95% or increase the viscosity 100 fold. At lower concentrations the enzyme requires up to a few days of reacting to reach the full reduction in viscosity. Pectinex™ Ultra SP-L has an optimum pH of 4.5-5 and a temperature optimum of 40° C. By controlling the viscosity available from the dried, treated highly refined cellulosic fiber compositions, tailored powder compositions can be provided that will provide precise viscosities when rehydrated in solutions at a constant concentration.

Автор: Koichi Kawaguchi, Shun Sato

Принадлежит: Yokohama Rubber Co Ltd

Disclosed is a process for producing a thermoplastic elastomer composition having a matrix phase comprising a polyamide and an ethylene/vinyl alcohol copolymer and a disperse phase comprising a rubber composition, by which gelation by a reaction between a polyamide and an ethylene/vinyl alcohol copolymer can be inhibited and the dispersion of the rubber composition can be good. In the process, the polyamide resin and the rubber composition are melt-blended to the extent necessary for the rubber composition to form a disperse phase, and then the ethylene/vinyl alcohol copolymer is added and further melt-blended together.
