摘要:The present invention is directed to compositions and methods for enhancing synthesis of nucleic acid molecules, particularly GC-rich nucleic acid molecules. Specifically, the invention provides compositions comprising one or more nitrogen-containing organic compounds having a formula selected from the group consisting of formula I and formula II (or salts or derivatives thereof), preferably 4-methylmorpholine N-oxide or betaine (carboxymethyltrimethylammonium), and further comprising one or more compounds selected from the group consisting of proline and an N-alkylimidazole compound, and more preferably proline, 1-methylimidazole or 4-methylimidazole. The invention further relates to methods for enhanced, high-fidelity synthesis of nucleic acid molecules, including via amplification (particularly PCR), reverse transcription, and sequencing methods. The invention also relates to nucleic acid molecules synthesized by these methods, to fragments or derivatives thereof, and to vectors and host cells comprising such nucleic acid molecules, fragments, or derivatives. The invention also relates to kits for synthesizing, amplifying, reverse transcribing or sequencing nucleic acid molecules comprising one or more of the compositions of the invention.

摘要:A reactor configuration comprises an inlet section I, a preheating section II, a transition section III, a reaction section IV and an outlet section V; except for the preheating section II and the reaction section IV, the existence of the inlet section I, the transition section III and the outlet section V depends on reaction conditions; and the process realizes no coke deposition synthesis of methane and high selectivity synthesis of ethylene. The methane conversion rate is 20-90%; ethylene selectivity is 65-95%; propylene and butylene selectivity is 5-25%; aromatic hydrocarbon selectivity is 0-30%; and coke deposition is zero.

标题 :Synthesis of beta phase spherical calcium pyrophosphate powder

权利人:OSRAM SYLVANIA INC
摘要:A fine, largely beta phase calcium pyrophosphate powder for, e.g., a diffuser coating for the interior surface of lamp envelopes. The powder is useful for electrostatic deposition of such coatings under varying conditions of environmental humidity. A process for the synthesis of the calcium pyrophosphate is also disclosed. Dibasic calcium orthophosphate (monetite) is dissolved in a dilute aqueous hydrochloric acid solution and spray-dried to form a calcium phosphate powder of spherically shaped hollow particles. The calcium phosphate powder is fired in air to convert the calcium phosphate powder to a spherical calcium pyrophosphate powder including the beta phase as a major component and the gamma phase as a minor component. For a diffuser coating, the poder is sonicated to fragment a portion of the hollow particles.

标 题 :In vivo synthesis of connective tissues
发明人：MAO JEREMY JIAN
权利人:UNIV COLUMBIA
摘要:The in vivo synthesis of connective tissue by fibroblast or fibroblast precursor cells ensconced within a biocompatible scaffold is disclosed. The cells are preferably present in a biocompatible scaffold such as gelatin and placed between two other biocompatible scaffolds such as collagen sponges soaked with a collagenic amount of a member of the TGF-β family of proteins. This composition is then implanted in a host to produce cranial sutures, periodontal ligament or other fibrous tissue structures in vivo.

标题:Low-temperature synthesis of polyaryletherketone resin onto nano/micron-scale inorganic seedbed
发明人：ZHANG XIANGCHENG
权利人:ZHANGJIAGANG XIANGCHENG MEDICAL MATERIAL SCIENCE AND TECH CO LTD
摘要:Disclosed is a low-temperature preparation method for a polyaryletherketone inorganic composite material, in particular a method for the low-temperature synthesis of a polyaryletherketone resin on a nano/micron-scale inorganic seedbed. The method comprises: adding nano/micron-scale inorganic material particles (mono-element or multi-element of aluminium oxide, silicon oxide, hydroxyapatite and the like) to a reaction system of a polyaryletherketone high-molecular polymer, and realizing the blending of inorganics in a high proportion (>50%) and organics while completing the one-step polymerization reaction, so that the common thermal degradation problem of the organic materials induced during the melting, blending and thermal processing is avoided. The composite material can be used in the technical fields of aerospace, industry, medicine and the like.

标 题 :Process for the synthesis of nanocrystalline phosphor particles and nanocrystalline phosphor particles obtainable by this process

权利人:KARLSRUHER INST TECHNOLOGIE
摘要:The present invention relates to a process for the targeted synthesis of inorganic phosphor particles which have a particle diameter from 1 to 100 nm, a virtually monodisperse size distribution in the range of ±20% and, depending on the class of material selected, a quantum yield of at least 20%, inorganic phosphor particles obtainable by this process and also their use for coating or embedding in a substrate selected from the group consisting of a paper, polymer, glass, metal or ceramic substrate, for example for diagnostics, therapy, as contrast agent, as marking, safety feature, for illumination and for data storage and/or data reproduction. A particular advantage of the phosphor particles which can be obtained according to the invention is, inter alia, that the particles have a surface finish which allows agglomerate-free redispersion in polar and nonpolar solvents or dispersion media. The choice of the dispersion medium allows the physicochemical properties of the phosphor particles which can be obtained according to the invention to be specifically matched to the requirements of a particular application.
