Leymus chinensis （Trin.） Tzveh is a rhizomatous perennial herbage of Gramineae. Reproduction is mainly by vegetative reproduction. Tillering nodes and rhizomes of L. chinensis serve as organs for both vegetative reproduction and nutrient storage. Water-soluble carbohydrate （WSC） contents were measured in tillering nodes, nodes and Internodes of rhizomes of different age classes of L. chinensis populations at three development stages, namely the dough ripe stage, the vegetative growth stage after full ripeness, and the withering stage, in two habitats： sandy soil and saline-alkaline soil. The results showed that WSC content in tillering nodes of the three age classes of L. chinensis were all markedly decreased with increasing age in both sandy soil and saline-alkaline solh A similar trend of changes In WSC contents was observed in the nodes and internodes of rhizomes in different age classes In both habitats. The highest WSC contents were in 2-age-class nodes and internodes of rhizomes, followed by those In the 1 age class, with the lowest WSC contents found in 3-age-class nodes and internodes of rhizomes at the dough ripe and vegetative growth stages after full ripening. In turn, WSC contents decreased with Increasing age at the withering stage in both habitats. The WSC content in each age class of internode was higher than that in the node of rhizome at three development stages in both habitats.

Recent advances in solid polymer electrolytes for lithium batteries

Nano Research 2017年第12期10卷 4139-4174页

作者： Qingqing Zhang Kai Liu fei ding Xingjiang Liu National Key Laboratory of Science and Technology on Power Sources Tianjin Institute of Power Sources Tianjin 300384 China School of Chemical Engineering and Technology Tianjin University Tianjin 300350 China

Solid polymer electrolytes are light-weight, flexible, and non-flammable and provide a feasible solution to the safety issues facing lithium-ion batteries through the replacement of organic liquid electrolytes. Substantial research efforts have been devoted to achieving the next generation of solid-state polymer lithium batteries. Herein, we provide a review of the development of solid polymer electrolytes and provide comprehensive insights into emerging developments. In particular, we discuss the different molecular structures of the solid polymer matrices, including polyether, polyester, polyacrylonitrile, and polysiloxane, and their interfacial compatibility with lithium, as well as the factors that govern the properties of the polymer electrolytes. The discussion aims to give perspective to allow the strategic design of state-of-the-art solid polymer electrolytes, and we hope it will provide clear guidance for the exploration of high-performance lithium batteries.

A New Method for Improving Strength and Plasticity of Steel Wire

引用

Journal of Materials Science & Technology 2007年第2期23卷 273-276页

作者： fei ding Guoyi TANG Zhuohui XU Shaoquan TIAN Advanced Materials Institute Graduate School at Shenzhen Tsinghua University Shenzhen 518055 China

Specially designed wire-drawing equipment with multiple electropulse generator was introduced. The influences of multiple electropulses processing on the microstructure and properties of the hardened steel wire were investigated. Samples treated by direct current under the same current density as that in multiple electropulses processing were carried out for contrast analysis. The results show that the optimized parameters of multiple electropulses processing will be facilitated to increase the nucleation rate and slow down the growth rate of recrystallized grains. Consequently, massive superfine grains of micro and sub-micro scale could be found in the steel wire. Thereby, the elongation was significantly enhanced with a relatively small strength reduction in comparison with as-received cold-drawing steel wires. Outstanding mechanical properties of steel wire were obtained.
