Ruthenabenzenes and Their Derivations as Catalysts for Transfer Hydrogenation of Aromatic Ketones

尽管“金属苯”被理论推测和成功合成迄今已20多年，也陆续有零散研究发现它们具有一些独特的光、电性能，但由于采用其他合成方法的烦琐和高难度以及所得金属苯化合物的稳定性问题，对其结构与性能关系的系统研究仍很少见报道，而对其潜在应用研究则刚刚起步。厦门大学夏海平教授及其课题组最近成功地合成了稳定的钌苯，该络合物为准八面体构型且含有两个单膦配体，与已发现的通式为[RuCl2(PPh3)2(N-N)](N-N=双齿氮配体)的Ru(II)催化剂在结构上具有相似性，因此推测钌苯及其衍生物可能应用于某些催化性能研究。本论文主要考察了钌苯体系催化氢转移氢化的性能，并从脯氨酸出发设计合成了一对新的手性三齿氮配体，...Although metallabenzenes were predicted and successfully synthesized 20 years ago, and then few researches on its photic and electric properties were reported; it was rarely found that metallabenzenes could be as catalysts for transfer hydrogenation of aromatic ketones and this was probably because most ruthenabenzenes are thermally labile at ambient temperature.

Decolorization of dyes by a current-producing bacterium Shewanella marisflavi EP1 isolated from sea sediments

以一株新筛选得到的海洋产电菌SHEWAnEllA MArISflAVI EP1作为实验材料,研究了该菌株关于偶氮、蒽醌、三苯基甲烷等染料的脱色能力及脱色机制。结果表明,该菌株对这些染料均具有较好的脱色能力,最高脱色容量达到925 Mg染料/(g细胞干重.d)。EP1能利用葡萄糖、蔗糖、木糖、乳酸、甲酸、柠檬酸等多种碳源将单偶氮染料丽春红2r脱色。脱色的PH、温度和nACl浓度范围分别是:PH 6-10、15°C-40°C、0-8%。最优脱色条件:乳酸,PH 8、35°C、1%-2%nACl,10 H内脱色率高达99.95%。分光光谱结果表明,在0-8%nACl浓度范围内EP1脱色机制为降解脱色。In this study,we investigated a new current-producing strain,Shewanella marisflavi EP1 isolated from costal sediments of Xiamen,its decolorization capability and mechanism of several types of dyes such as azo,anthraquinone and triphenyl methane.The results indicated that these dyes could be decolorized efficiently and the maximum capacity was 925 mg/(g cell dry weight·d) of Malachite Green.Strain EP1 could utilize various kinds of carbon sources,such as glucose,sucrose,xylose,lactate,formate and citrate for the decolorization of Xylidine Ponceau 2R.EP1 was active for decolorization in wide ranges of pH(6?10),temperture(15 °C?40 °C),and NaCl concentations(0?8%).The optimal conditions were pH 8.0,30 °C,1%?2% NaCl and lactate as carbon source,with a highest decolorization rate of 99.95% within 10 h.UV-vis absorption spectra demonstrated that the mechanism of the azo dye was degradation in the range of 0?8% NaCl.中国大洋协会项目(No.DYXM-115-02-2-15);国家海洋局海洋生物遗传重点实验室开放研究基金资助项目(No.HY200904

以苯乙酮与间苯二甲酸甲酯为原料经由Claisen缩合制备了1,3-二(3-苯基-3-氧代丙烯醇)苯(BPOB).用元素分析、MS、1H NMR、UV吸收光谱、X射线单晶衍射和固体CD光谱等对其进行了表征.晶体结构数据显示,BPOB属于Sohncke空间群P212121,UV和1H NMR谱表明,BPOB在溶液中主要以烯醇式存在,固体CD光谱和重结晶实验证明,BPOB手性晶体的形成是结晶诱导的绝对不对称合成.1,3-bis(3-phenyl-3-oxopropanoyl)benzene (BPOB) was prepared by Claisen condensation of aceto-phenone and dimethyl isophthalate and characterized by elemental analysis, MS, 1H NMR, UV absorption spectrum, solid-state circular dichroism (CD) spectra, and X-ray single-crystal diffraction. The X-ray crystallographic data indicated that BPOB crystallized in a Sohncke group P212121, UV and 1H NMR showed that the enol tautomer was the most dominant form in solution, and the solid-state CD spectra and repeated recrytallization revealed that the formation of chiral BPOB crystals could be regarded as crystallization-induced asymmetric synthesis.国家自然科学基金(20773098);; 福建省自然科学基金(2005YZ1020);; 厦门大学科技创新工程基金(系列2,XDKJCX20061027)资

Proton Conduction of Mesoporous Phosphorus Hybrid SiO_2 at Temperature Range 30℃～200℃

合成了孔壁掺磷中孔SIO2(M-PH-SIO2),其bET比表面积为407M2g-1,bJH平均孔径为6.1nM。用交流阻抗技术测定了除去游离P2O5的掺磷中孔SIO2在30℃~200℃范围内100%相对湿度下的质子电导,样品导电率随温度升高而升高,在150℃和100%相对湿度下,样品的电导可达3.1x10-3S·CM-1,比纯中孔SIO2(M-SIO2)的电导约高一个数量级,原因是M-PH-SIO2的物理吸附水量为31个分子/nM2,而M-SIO2只有24个分子/nM2。The mesoporous SiO2 with P2O5 hybrid in the pore walls(m-PH-SiO2) but not impregnated in the pore tunnels was synthesized.The BET surface of m-PH-SiO2 was 407m2g-1 and the average pore size was 6.1nm.The proton conductivity at temperature range 30℃ ～ 200℃ under 100% RH of the washed m-PH-SiO2 were measured by AC impedance technique.The conductivity of m-PH-SiO2 was enhanced with the increase of temperature,the value of proton conduction at 150℃ under 100% was 3.1 × 10-3 S·cm-1 higher than that of pure mesoporous SiO2(m-SiO2 ) beacaus the m-PH-SiO2 can hold more H2O molecule.The number of H2O molecule on internal surface of m-PH-SiO2 was about 31 per nm2,and the value in m-SiO2 was only 24 per nm2 at the same condition.科技部十一五“863”计划(2008AA05Z107);华南理工大学学生研究计划(SRP

Historical Survey of the Parent-child Relationship

亲子关系是家庭法的核心,是亲属法的重要组成部分。但是,亲子关系并非一成不变,亲子关系在漫长的历史中经历着巨大的变化。即经历着从家父权威到父母责任、从家族本位到子女本位、从父权优先到儿童最佳利益和从为族收养到为子女收养的脉络变迁。这些变化是与儿童观及儿童的地位变化相契合的。父母子女之间的关系已不再是父母权威占据主导地位,父母权利具有义务性,转而成为父母责任,亲子立法上也偏向于子女本位并坚持儿童最佳利益原则。亲子关系的变迁反映了国际社会对儿童及其权利的重视。Parent-child relationship is the core of family law and an important part of the law of kindred.However,parent-child relationship is not invariable,and this relationship has experienced tremendous changes in the long history.Parent-child relationship has experienced several development veins: from patria potestas to parental responsibility; from clan departmentalism to child-oriented concept; from patriarchy priority principle to the best interests of the child; and from adoptions for clan to adoption for children.These development veins are in association with the changes in the views on children and their rights.And these changes reflect the attention of international community to children and their rights.福建省教育厅2012年度课题“国际公约框架下两岸儿童权利立法比较研究”(项目编号:JB12208S); 闽江学院2011年度育苗项目“国际立法框架下两岸儿童权利比较研究——从法律社会学之视域”(项目编号:YSY1110)的阶段性研究成
