摘要:
1-13C-1,1-Bis(acetoxy(methyl))-2,2′-cyclopropane of formula (I): The compound can be hyperpolarized and used as a contrast agent in 13C Magnetic Resonance diagnostic technique (13C-MR) for the diagnosis of tumor.
摘要:
Methods and compositions comprising an emulsion or a microemulsion for use treating an oil and/or gas well are provided. In some embodiments, the emulsion or the microemulsion comprises an aqueous phase, a solvent, a surfactant comprising alkyl polyglycoside, an alcohol, and, optionally, one or more additives.
摘要:
Described is a method of detecting and/or determining levels of incorporation of monolignol ferulate conjugate esters into lignin by derivatizing the lignin, reductively cleaving the lignin, labeling the cleavage products, and then detecting cleavage products derived from monolignol ester conjugates via differential attachment of the label.

摘要:
This invention relates generally to enantiomerically enriched C—H activated ruthenium olefin metathesis catalyst compounds which are stereogenic at ruthenium, to the preparation of such compounds, and the use of such catalysts in the metathesis of olefins and olefin compounds, more particularly, in the use of such catalysts in enantio- and Z-selective olefin metathesis reactions. The invention has utility in the fields of catalysis, organic synthesis, polymer chemistry, and industrial and fine chemicals chemistry.
摘要:
Monomers, polymers and copolymers are provided that incorporate at least one naturally occurring phenolic compound, such as a plant phenol, as well as methods for producing the monomers and polymers. Plant phenols possessing a reactive group in addition to the phenolic group, such as a double bond, aldehyde, ester, alcohol or carboxylic acid, are particularly useful. Plant phenols can be isolated from a plant material, or chemically or enzymatically synthesized.
摘要:
A reagent that enhances acid generation of a photoacid generator and composition containing such reagent is disclosed. Also described is a method for manufacturing a device, the method including applying a liquid containing a composition to a member such that a coating film including the composition is formed on the member; and exposing the coating film to at least one of a first electromagnetic ray and a first particle ray such that a first portion of the coating film is exposed to the at least one of the first electromagnetic ray and the first particle ray while a second portion of the coating film is not exposed to the at least one of the first electromagnetic ray and the first particle ray.
摘要:
The present invention relates to a method for the production of unsaturated fatty acids with at least two double bonds. The invention furthermore relates to the use of nucleic acid sequences SEQ ID NO: 1, 3, 5, 9, and 11 encoding polypeptides having desaturase or elongase activity in the method and for generating a transgenic organism, preferably a transgenic plant or a transgenic microorganism, with an increased content of fatty acids, oils or lipids with unsaturated C18-, C20-, or C22-fatty acids, and to their homologs or derivatives, to gene constructs encompassing these genes, and to their use alone or in combination with biosynthesis genes of polyunsaturated fatty acids. The invention also relates to multiexpression cassettes for seed-specific expression, and to vectors or organisms which encompass a desaturase gene alone or in combination with further desaturases and/or elongase genes or homologs using said expression cassettes.
