二维纳米片构建的层状纳滤膜在工业染料和含盐废水的净化处理中显示出广泛的应用前景,但纳米片间松散的层状结构会影响过滤通道的稳定性,导致对盐类的截留效果不理想.本文以均苯三甲酰氯(TMC)交联单宁酸(TA)官能化的二硫化钼(MoS2)纳米片构建薄层复合纳滤膜,以解决二维材料构建层状纳滤膜的常见问题.所制备的纳滤膜不仅对荷负电染料(伊文思蓝,分子量960.8)有很高的截留率(>98.5%),也能很好地选择性分离染料-盐混合溶液(NaCl截留率<15%).同时,该膜还能在严苛环境中保持优秀的稳定性.此外,在近红外光照射下,MoS2纳米片显著的光热转换效应赋予薄层复合纳滤膜一定的抗菌能力,使得该膜在实际应用中具有巨大潜力.

Comparison of seed setting rate, plant height and cheng's morphological traits were made between the F2progeny of indica-japonica hybrids, 02428/Pei'ai 64 and Taichung 65/Teqing. There existed resemblance normal distribution in plant height, and the distribution had no relationship with the seed setting rate and plant height in F1progeny, suggesting that there were no gametic selection for the plant height in the F2progeny of indica-japoniea hybrids. An average seed setting rate of the F2was equal to the F1populations in the recombination of 02428/Pei'ai 64 in which there was an excellent cross compatibility, but the remarkable increase in the seed setting rate from the F1to F2in Taichung 65/Teqing, indicating that gametic selection only took place in the indica-japonica crosses with low cross compatibility while null or little in the hybrids with high compatibility. There were many intermediate types among the leaf pubescence, color of hull at heading, and length of the first and second panicle internode, and these cheng's morphological traits was distributed normally; there were also a little intermediate types in hull hairness and phenol reaction with bi-peak distribution; while length to width ratio of grain was inclined to the japonica types obviously showing a skewed distribution in the F2 population. Although cheng's morphological traits in F2populations had inconsistent distribution types, cheng's morphological traits index showed normal distribution, which suggested that intermediate types, i.e. indicalinous or japonicalinous, were primary in F2population.

作者： Ning-Yi Wang Shuo Gao zhu-Di Shu Bei-Bei cheng Chun Ma Yu-Chen Zhang Feng Shi Research Center of Chiral Functional Heterocycles School of Chemistry and Materials Science Jiangsu Normal University School of Petrochemical Engineering Changzhou University School of Chemistry and Chemical Engineering Henan Normal University

The first catalytic atroposelective synthesis of indole derivatives bearing N-N/C-C diaxes has been established by the strategy of de novo ring formation. By this strategy, various indolyl quinazolinones bearing vicinal N-N/C-C diaxes were synthesized in high yields with overall good diastereoselectivities and excellent enantioselectivities via chiral phosphoric acid-catalyzed onepot asymmetric formal (5+1) cycloaddition/oxidation reaction. Moreover, such indolyl quinazolinones bearing vicinal N-N/CC diaxes have good configurational stability and could be converted into new chiral ligands with applications in asymmetric catalysis. Therefore, this work not only offered a new member for the family of diaxial atropisomers, but also provided a powerful strategy for catalytic asymmetric synthesis of atropisomers bearing N-N/C-C diaxes.
