标题:普鲁卡因在水和胶束介质中水解的动力学
摘要:普鲁卡因的碱性水解的伪一阶条件下的动力学([oh-]»[普鲁卡因])已被进行.N,N-二乙基氨基乙醇和p获得了氨基苯甲酸根阴离子作为水解产物.发现水解速率与[naoh]线性相关.阳离子十六烷基三甲基溴化铵(ctab),十二烷基三甲基溴化铵(ddtab)和十四烷基三甲基溴化铵以及阴离子十二烷基硫酸钠(sds)胶束的加入均抑制了水解速率.Sds胶束对反应速率的抑制作用最大,而阳离子表面活性剂中ctab抑制作用最大.胶束介质中普鲁卡因水解速率的变化归因于反应分子对表面活性剂的取向以及普鲁卡因与胶束的结合常数.在dtbab胶束中普鲁卡因的水解速率可忽略不计.基于假相离子交换模型对存在阳离子胶束的观察结果进行了处理.用假相模型处理在阴离子胶束存在下获得的结果,并确定各种动力学参数.©2012 Wiley Periodicals,Inc.国际化学杂志kinet 45:1-9,2013

标题:Scale up synthesis of silicasome nanocarriers

摘要:In order to facilitate the approval and commercialization of silicasome drug delivery systems (e.g. irinotecan silicasomes) it is necessary to scale up synthesis of the drug-loaded silicasomes. In this regard, it was discovered that the synthesis protocols used for laboratory synthesis of drug-loaded silicasomes (e.g., 500 mg/batch) do not scale to large scale silicasome production, because the resulting products were too heterogeneous for use as pharmaceuticals. Accordingly, new methods are provided herein that effectively afford the large-scale production of mesoporous silica nanoparticles (MSNPs) and lipid bilayer coated MSNPs (silicasomes).

标题 :Method for the synthesis of metal nanoparticles in aqueous environment without the use of shape directing agents
发明人：MOGLIANETTI MAURO; POMPA PIER PAOLO
权利人:FONDAZIONE ST ITALIANO TECNOLOGIA
摘要:The present disclosure relates to a seed-growth based method for the synthesis of metal nanoparticles of controlled shape (cubes, cuboids, octahedrons) and size in an aqueous environment, without the use of shape directing agents. The method involves a first step of preparing a solution comprising water, metal seed growth nanoparticles, a metal salt comprising the same metal as the metal seed growth nanoparticles, and a reducing agent; and a second step of heating the solution to between 9 and 130° C. at a rate of between 1° C./min and 5° C./min and at a pressure of between 1 and 5 atm. The method may also be carried out in a reduced oxygen atmosphere and the concentration of oxygen disclosed in the solution may be less than the concentration of oxygen in an oxygen saturated solution.

摘要:This invention provides improved polypeptides, including dioxygenases, dehydrogenases, ligases and transferases that are useful for the biocatalytic synthesis of compounds such as α-hydroxycarboxylic acids, and aryl- and alkyl-hydroxy and carboxylic acid compounds. The polypeptides provided herein are improved in properties such as regioselectivity, enzymatic activity, stereospecificity, and the like. Methods for obtaining recombinant polynucleotides that encode these improved polypeptides are also provided, as are organisms that express the polypeptides and are thus useful for carrying out said biocatalytic syntheses. Also provided by the invention are methods for increasing said solvent resistance of organisms that are used in the synthetic methods.

摘要:A template-free reverse micelle (RM) based method is used to synthesize pyrochlore nanostructures having photocatalytic activity. In one embodiment, the method includes separately mixing together a first acid stabilized aqueous solution including pyrochlore precursor A and a second acid stabilized aqueous solution including pyrochlore precursor B with an organic solution including a surfactant to form an oil-in-water emulsion. Next, equimolar solutions of the first and second acid stabilized oil-in-water emulsions are mixed together. Then, the mixture of the first and second acid stabilized oil-in-water emulsion is treated with a base to produce a precipitate including pyrochlore precursors A and B. After which, the precipitate is dried to remove volatiles. The precipitate is then calcined in the presence of oxygen to form a pyrochlore nanostructure, such as a bismuth titanate (Bi 2 Ti 2 O 7 ) pyrochlore nanorod. The method of synthesizing the pyrochlore nanorod is template-free.
