标题:Odd-even Effect And Unusual Behavior Of Dodecyl-Substituted Analogue Observed In The Crystal Structure Of Alkyltrimethylammonium-[ni(Dmit)2]−salts
摘要:一系列[ni(Dmit)2]−(dmit:1,3-二硫杂环戊烯-2-硫酮-4,5-二硫醇)的烷基三甲基铵盐(cn:N代表烷基链长度;N = 3和5-18)已被制备并通过x射线结构分析进行了研究.所有复合盐均被发现由交替的[ni(Dmit)2]−阴离子层和阳离子层组成,阳离子层的烷基链存在显著的互插结构.然而,分子排列在(C3)[ni(Dmit)2]和其他(Cn)[ni(Dmit)2](n = 5-18)之间有所不同.在c3复合盐中,相邻的阳离子沿[ni(Dmit)2]−阴离子的长轴排列,而在其他(c5-c18复合盐)中,它们朝向短轴排列.这种排列差异源于阳离子和阴离子长轴长度的相关性,即clca.此外,对于c10-c18,阳离子烷基链与[ni(Dmit)2]−阴离子之间的相对取向在奇数和偶数编号阳离子之间有所不同.奇数编号阳离子的烷基链平面垂直于[ni(Dmit)2]−阴离子平面,而偶数编号阳离子的烷基链平面则平行.还发现c12类似物表现得像奇数编号阳离子.然而,在c12盐中,十二烷基的末端甲基采取了不寻常的末端-旁式构象.

标题:Scale up synthesis of silicasome nanocarriers
发明人：NEL ANDRE E; MENG HUAN; LIU XIANGSHENG
权利人:UNIV CALIFORNIA
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 :Electrochemical synthesis of organic carbonates
发明人：CIPRIS DIVNA; MADOR IRVING L
权利人:ALLIED CHEM
摘要:A process is described for the electrochemical synthesis of organic carbonates, such as dimethyl carbonate and ethylene carbonate, useful as industrial solvents for polymers and resins, which comprises electrolyzing a liquid medium containing a nonfluoride halide-containing electrolyte and a paraffinic monohydric or 1,2-dihydric alcohol. The non-fluoride halide-containing electrolyte is present in an amount of about 0.01 to 10 weight percent of the alcohol used, and the electrolysis is conducted by passing a direct current through the liquid medium at a temperature below its boiling point and under a carbon monoxide atmosphere at a pressure of about 1 to 350 atmospheres.

摘要:The present invention provides a template-directed self-assembly strategy to integrate the class of materials called dendrimers with periodic mesoporous and macroporous silica materials to create two totally new classes of organic/inorganic nanocomposite materials, which we call periodic mesoporous dendrisilicas (PMeDs) and periodic macroporous dendrisilicas (PMaDs). The unusual combination of inorganic silica and organic dendrimer chemical structures with these scales of porosity and surfaces suggests a myriad of uses for PMeDs and PMaDs, such as the controlled release and uptake of chemicals, chiral separations and catalysis, electronic printing and microelectronic packaging, biomaterial platforms, chromatography stationary phase, and photonic crystal applications. These applications target the synergistic relationship between the dendrimer and the meso- or macroporous structure within a single hierarchical nanostructured organic/inorganic hybrid material.

标题:Solventless synthesis of hydrophilic phenol ester derivatives
发明人：MAJERCZAK VICTORIA ANN; GIBSON MICHAEL STEVEN; ORLANDO ROBERT JAMES
摘要:Process for preparing benzenesulfonate salts from an appropriately substituted acid chloride and a hydroxybenzenesulfonic acid is conducted in the absence of solvent, in a molar excess of acid chloride and in the presence of a phase transfer catalyst selected from quaternary ammonium and quaternary phosphonium salts and the target reaction product. The molar excess of the acid chloride is used to reduce the occurrence of gelation in the product.

摘要:A method of preparing mesoporous nanostructured particles of a transition metal oxide. The method contains the steps of dissolving a soft-template compound in a solvent, dispersing a first or second row transition metal ion-containing compound, adjusting the pH value if necessary, and removing the solvent to obtain mesoporous nanostructured transition metal oxide powders, calcining the powders optionally to afford mesoporous nanostructured particles of the transition metal oxide. Also disclosed is particle prepared by the above-described method.

摘要:Provided is an auto-thermal evaporative liquid-phase synthesis method for cathode material for battery, comprising the following steps: (1) Adding a synthetic raw material of cathode material into a solvent to obtain a mixture A, the synthetic raw material of the cathode material containing lithium source, adding an accelerant into the mixture A, which makes the mixture A achieve a strong auto-thermal reaction to release heat to evaporate the solvent, and obtaining a solid precursor of the cathode material; (2) Drying the precursor, sintering in an atmosphere furnace and obtaining the cathode material. The method is simple in process, low in energy consumption, requirements for equipment and cost, and is applicable to industrial mass production and application. The cathode material obtained through the method is stability in batch, easy to process, low in internal resistance and high in capacity and has an excellent charging and discharging performance.
