摘要:The present invention relates to a method for the in situ synthesis of of MOFs (metal organic frameworks), COFs (covalent organic frameworks), and ZIFs (Zeolitic imidazolate framework), onto and within different types of porous substrates, and their applications. The present invention provides a unique and easy to utilize method by which a number of MOFs, COFs and ZIFs can be synthesized directly onto and within a porous substrate with high performance efficiency ensuring higher grammage in formation of adsorbent product onto and within the substrate.

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:Modular approach to on-line synthesis, drug discovery and biochemical transformations using immobilized enzyme reactors
发明人：WAINER IRVING; MARKOGLOU NEKTARIA
摘要:A coupled system using extremely different enzymes with incompatible cofactors and reaction conditions has been constructed using standard liquid chromatographic formats and open tubular formats. One of the significant aspects of the present invention lies in the development of the liquid chromatographic on-line enzyme cascade. This has been illustrated by the biosynthetic pathway involving dopamine beta-hydroxylase and phenylethanolamine N-methyltransferase which encompass the synthesis of the key neurotransmitters, norepinephrine and epinephrine. The results demonstrate for the first time the immobilization of dopamine beta-hydroxylase and phenylethanolamine N-methyltransferase. The IMERs are active and can be used in a liquid chromatographic format for qualitative and quantitative determinations. The IMER-HPLC system can be used to carry out standard Michaelis-Menten enzyme kinetic studies and to quantitatively determine enzyme kinetic constants, identify specific enzyme inhibitors, provide information regarding the mode of inhibition and the inhibitor constants (K i ). A second significant aspect of the present invention lies in the ability of the immobilized enzyme reactors to be used independently or as a combination, thus providing a unique opportunity to explore the interrelationships between these enzymes, to investigate the source of diseases and to design new drug entities for identified clinical syndromes.

摘要:##STR1## By dehydrating indolines or their salts, the corresponding indoles having formula (I) are obtained. In the formula, R 1 and R 3 represent independently from each other hydrogen or alkyl groups with 1 to 4 C atoms, R 2 stands for hydrogen, a methyl or a carboxyl group, R 4 and R 5 represent independently from each other hydrogen, amino groups, hydroxy groups, alkyl groups with 1 to 4 C atoms or alkoxy groups with 1 to 4 C atoms, or, in case R 4 and R 5 are bound to adjacent C atoms, both residues may also represent together an alkylene dioxy group with 1 to 4 C atoms. This process allows high yields of very pure indoles to be produced.

摘要:A new method for preparing salts of metal cations and organic acids, especially divalent salts of alkaline earth metal ions from group II of the periodic system and carboxylic acids. The method comprising the use of a high temperature (about 90° or more) and, optionally. high pressure, in order to obtain a higher yield, purity and faster reaction speed than obtained with known synthesis methods. In particular, the present invention relates to the production of strontium salts of carboxylic acids. Novel strontium salts are also provided by the present method.
