标题:迈向介孔结构的咪唑锌锌骨架
摘要:超分子模板向金属有机框架领域的转移为新颖的分层结构材料的设计开辟了新途径.我们展示了在阳离子表面活性剂十六烷基三甲基溴化铵(ctab)存在下的介孔结构化咪唑锌的首次合成,它作为模板产生了有序的层状杂化材料.通过粉末x射线衍射,电子衍射以及固态NMR和ir光谱确定了原子和中尺度的高度有序.获得的甲基咪唑锌和咪唑锌物种的晶胞度量为a =(11.43+/-0.45),B =(9.55+/-0.35),C =(27.19+/-0.34)å和a =(10.98+/-0.90),假设正交对称,B =(8.95+/-0.95),C =(26.33+/-0.34)å.推导的结构模型与由溴封端的(甲基)咪唑酸锌链与运动刚性的阳离子表面活性剂分子以全反式交织而成的介层结构一致构象.杂化材料在高达300oc的温度下表现出异常高的热稳定性,此时ctab消失,并获得了热诱导转变为具有较大特征尺寸的不良晶体介观结构的证据.乙醇处理可从材料中

标题:Scale up synthesis of silicasome nanocarriers
发明人：NEL ANDRE E; MENG HUAN; LIU XIANGSHENG

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).

发明人：MATVEEVA EVGENIA; VALENCIA RAMONCITO MAGPANTAY; WERNER MARTINA ELISABETH
摘要:Optical bio-disc assays and synthesis of bio-active nanoparticles and nanocapsules for use therewith. Related methods for synthesis of polymeric nanoparticles for use in disc assays include forming reverse micelles having an outer non-polar shell and an inner polar cavity and solubilizing in the reverse micelles a polymerizing mixture including monomers, co-monomers, weakly polar monomers, and/or polymerizable surfactants. This may also include an initiator of polymerization. The methods also include polymerizing the mixture. The invention is also directed to the use of the nanoparticles and nanocapsules in optical bio-disc assays for the detection of analytes including nucleic acid sequences. Related optical assay discs and disc systems are also provided.

摘要:This invention describes the self-assembly of meso(nano)porous silica particles from inorganic an inexpensive silica precursor, sodium silicate. The particles have a well defined shape, high surface area, and high uniformity of the pore size, the properties that are typically found for high quality mesoporous material synthesized from organic silica precursors. The disclosure illustrates a synthesis of hard spheres, discoids, and a mixture comprising discoids, gyroids and fibers, termed as origami.

权利人:NANJING UNIVERSITY OF TECHNOLOGY
摘要:The invention relates to a method for preparing a hierarchical porous zeolite membrane and an application thereof, comprising the following steps: a mesoporous structure-directing agent is added to limit the growth of zeolite crystals, and self-assembled in the crystallization process to generate a mesoporous structure. Based on a seed crystal induced secondary nucleation mechanism, this method can realize one-step hydrothermal synthesis of hierarchical porous zeolite membrane with the advantages of mild and controllable synthesis conditions, simple process, good repeatability, reduced energy consumption and cost savings. The hierarchical porous zeolite membrane prepared by the method has good cut-off performance, and the cut-off molecular weight is adjustable between 200 to 500,000 Da.
