摘要:The present disclosure relates to the field of synthesis of block copolymers, and polymeric nanofibers having a core-shell morphology produced therefrom. The present disclosure relates to the field of synthesis of block copolymers where one block is more hydrophobic than the other block and is a different composition. The disclosure also relates to uses of these polymeric nanofibers in various applications, such as reinforcing a polymeric matrix and for coatings applications.

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.

标题:One step synthesis of ultrahigh molecular weight block copolymers
发明人：URBAN MAREK W
权利人:UNIV CLEMSON; UNIV CLEMSON RES FOUNDATION
摘要:Single-step synthesis processes for production of ultrahigh molecular weight block copolymers are described. The ultrahigh molecular weight copolymers can have a molecular weight of about 10 6 or greater and can be formed within a few hours in a surfactant-free environment. The formation process is controlled by initiator-starvation conditions in a sequential polymerization of monomers exhibiting different solubility in the solvent.

摘要:Carbohydrate of Formula (A)where R1 is H and n an integer from 1 to 5, is synthesized by reacting, under heating, compound (A0)with HO—(CH2)n—CHâ•?CH2 in the presence of an acid capable of liberating a proton, and cooling the reaction mixture to obtain a cooled mixture comprising compound (A).Carbohydrate of Formula (AAPG)where R2 is a monovalent protecting group, PG is a divalent protecting group and n an integer from 1 to 5, is synthesized by reacting, in the presence of a metal-containing zeolite, compound of Formula (APG)with compound of Formula (A1)where X is —I, —Br, —Cl, —CN, —OTf (Triflate), —OMs (Mesylate), —OTs (Tosylate), methylsulfate, or trichloroacetimidate. Deprotection of compound (AAPG) forms compound (AA)Carbohydrates (A) and (AA) can be coupled with a thiolated linker to form glycoconjugate precursors, which in turn are conjugatable with a carrier material such as a protein, peptide or polypeptide.
