摘要:A technique to synthesize complex oxide ceramic powders which offers advantages of both the coprecipitation and sol-gel routes while doing away with the disadvantages is disclosed. Namely, the ability to achieve chemical homogeneity and crystallite size on the namometer length scale at a nonprohibitive cost is provided by the disclosed method. In one embodiment of the invention, a method for the synthesis of a mixed metal oxide powder is provided including (a) combining a liquid absorbent resin with at least one solution selected from the group consisting of solutions containing at least one organo-metallic compound and solutions containing at least one metallic salt compound, such that at least two metals are present in the liquid absorbent resin after the combining is completed; (b) after the combining, allowing the liquid absorbent resin to swell and gel and thereby form a swollen gel; (c) preparing a precursor material by changing at least one of the pH and temperature of the swollen gel; (d) pyrolyzing the precursor material to form a pyrolyzed precursor material; and (e) calcining the pyrolyzed precursor material to form a mixed metal oxide powder.

发明人：HUDECEK SLAVKO; HUDECKOVA IVANA; CEFELIN PAVEL
权利人:CESKOSLOVENSKA AKADEMIE VED OF
摘要:Graft copolymers are formed having a backbone formed by monomeric units, selected from the group of vinyl monomers comprising acrylates, methacrylates, acrylamide, styrene and N-vinyl-2-phyrrolidone, and side branches formed by 10-80 wt. % of oligourethanes based on aliphatic, aromatic and alkylaromatic diisocyanates and low-molecular-weight diols with 2-4 carbon atoms in the molecule. The graft copolymers are prepared in two steps: the first step consists in the synthesis of oligourethane with the terminal unsaturated group; the second step is the radical copolymerization of this oligourethane with the above vinyl monomers.

发明人：MORI KENJIRO; MAETA ERI
权利人:NITTO DENKO CORP
摘要:According to the invention, there is provided a solid-phase support for nucleic acid synthesis, which is constituted of a porous copolymer particle containing a multifunctional vinyl monomer unit having two or more vinyl groups in one molecule and a monofunctional vinyl monomer unit having one vinyl group in one molecule, in which the solid-phase support has a swelling volume when soaked in acetonitrile of 3.5 ml/g or more and has a median particle diameter measured by a laser scattering particle size distribution measuring method within a range of from 50 to 120 µm. According to the solid-phase support for nucleic acid synthesis of the invention, a high-purity nucleic acid can be synthesized with a high yield.

标题 :Synthesis of vinyl polymers by controlled radical polymerization
发明人：WHITE DANIELA; O'DWYER JAMES B
权利人:PPG IND OHIO INC
摘要:A controlled free radical polymerization process, which includes the steps of: adding a monofunctional iniferter compound to an oxygen-free solvent; heating the solution to a temperature sufficient to allow the iniferter compound to form two carbon centered radical residues; adding a first monomer composition comprising one or more monomers to the solution containing the radical containing residues; polymerizing the first monomer composition to form a quasi-living polymer; and optionally polymerizing a second monomer composition comprising one or more monomers, which are different than the first monomer composition. The resulting non-random copolymer having the general formula:n nφ-[-A p -B s -] t -φn nwhere A and B are different compositions of ethylenically unsaturated monomers; p is an integer from 1 to 1,000; s is an integer from 0 to 1,000; t is an integer from 1 to 100; and φ is a residue from the iniferter.

发明人：ANDERSON DANIEL G; LEVENBERG SHULAMIT; LANGER ROBERT S
摘要:A method of screening cell-polymer interactions. The method includes depositing monomers as a plurality of discrete elements on a substrate, causing the deposited monomers to polymerize, thereby creating an array of discrete polymer elements on the substrate, incubating the substrate in a cell-containing culture medium, and characterizing a predetermined cell behavior on each polymer element.

摘要:The invention relates to the synthesis of polymers containing self-complementary quadruple hydrogen groups by copolymerizing monomers containing a quadruple hydrogen bonding group with one or more monomers of choice. The resulting polymers show unique new characteristics due to the presence of additional physical interactions between the polymer chains that are based on multiple hydrogen bonding interactions (supramolecular interactions).
