Lithium batteries (LBs) have become increasingly important energy storage systems in our daily life. However, their practical applications are still severely plagued by the safety issues from liquid electrolyte, especially when the batteries are exposed to mechanical, thermal, or electrical abuse conditions. Gel polymer electrolytes (GPEs) are being considered as an effective solution to replace currently available organic liquid electrolyte for building safer LBs. This review provides recent advancements in GPEs applied for high-performance LBs. On the one hand, from the environmental and economic point of view, the skeletons of GPEs changed from traditional polymer to renewable and degradable polymer. On the other hand, in addition to being as a component with good electrochemical and physical characterizations, the GPEs also need to provide some functions for addressing the concerns of lithium (Li) dendrites, unstable cathode electrolyte interface, dissolution and migration of transition metal ions,"shuttle effect" of polysulfides, and so on. Finally, to synchronously meet the challenges from the advanced cathode and Li metal anode, the bio-based GPEs with multi-functionality are proposed to develop high-energy/powerdensity batteries in the future.

绞股蓝Gynostemma pentaphyllum富含多种营养成分,具有多种功能,例如治疗血尿、咽和颈部水肿、抗肿瘤等。天然产物的结构不同,它们表现出不同的抗菌和抗肿瘤机制。本论文中,我们调查了绞股蓝皂苷对人肝癌细胞Hep G2、绞股蓝皂苷ⅩⅦ对人宫颈癌Hela细胞的抑制作用,并进一步研究了其分子机制。主要研究结果如下:（1）绞股蓝皂苷对人肝癌细胞Hep G2的抑制作用及其分子机制。在细胞存活率、细胞周期和诱导Hep G2癌细胞凋亡的基础上,评估了Stevenleaf（SV）的抗癌活性。SV处理诱导Hep G2停滞在G0/G1期,24h和48h的IC50值分别139.82μM和119.12μM;SV处理诱导诱导细胞凋亡并增强细胞内ROS的产生。对于细胞周期相关基因,SV上调p21、p-27、p-53的m RNA表达,下调Cyclin-A、Cyclin D1、Cyclin-E和CDK1/2。SV有效促进细胞受体相关TNF-R1、TRADD1和FADD的表达、下调Caspase-8基因的表达;SV处理后,线粒体途径的Bax、Bak、Cyt c、Apaf1、Caspase 3和Caspase9基因表达量上调,Bcl2、Bcl-xl和Bad基因的表达量下调。SV通过Akt和AMPK激活在Hep G2细胞中诱导m TOR介导的细胞凋亡。（2）绞股蓝皂苷ⅩⅦ对人宫颈癌Hela细胞的抑制作用及其分子机制。MTT法用于评估gypenoside ⅩⅦ对Hela细胞的抑制作用,通过Hoechst 33342染色和Annexin V-PI染色鉴定凋亡细胞死亡和凋亡,细胞周期分析用于鉴定细胞四个阶段（G0/G1,S和G2/M期）中的细胞比例。gypenoside ⅩⅦ处理后,细胞的抑制作用随浓度的增加而增加,细胞明显凋亡。与正常细胞相比,G0/G1期的细胞比例增加,而S和G2/M期的细胞比例降低。此外,gypenoside ⅩⅦ处理有效调控死亡受体途径和线粒体途径的基因表达。通过Caspase-8和caspase-9蛋白抑制剂的作用,进一步证明了gypenoside ⅩⅦ诱导Hela细胞的凋亡。上述结果表明绞股蓝皂苷和绞股蓝皂苷ⅩⅦ对癌症细胞具有显著的抑制作用,具有进一步开发为抗癌药或功能性食品的价值。

Catalytic activity and selectivity of prepared catalysts (Fe2O3/ and Fe2O3/AC(KOH)) were investigated for liquid phase aerobic oxidation of primary and secondary alcohols, in a batch reactor, using solvent free condition and/or eco-friendly solvents. The catalysts were characterized by SEM, EDX, XRD, FTIR, TGA/DTA, and surface area and pore size analysis. Experimental data revealed that Fe2O3/AC(KOH) was an efficient catalyst for the oxidation (dehydrogenation) of alcohol while was found to show catalytic activity for both dehydration and dehydrogenation of alcohols. The catalysts were recycled by simple filtration, and used several times without any loss of catalytic activity.

Rice （Oryza safiva L.） is highly susceptible to the rhizosphere salinity than other cereals. High sensitivity has been ob- served, mainly at vegetative and reproductive stages in rice. It is the duty of plant physiologists to comprehend the growth, development, and physiological processes of rice plants under stress. This paper includes the overview of rice growth and developmental processes influenced by salt stress and the regulation pathways involved in these processes. It also includes the promising salt tolerance strategies, i.e., genetic modification techniques, agronomic practices to improve rice growth, yield; and role of phytohormones and their management, especially inhibition of ethylene biosynthesis by using inhibitors 1-methylcyclopropene （1-MCP）. Rice cultivation may be a first choice for improvement of salt tolerance through plant growth regulators and improved cultivation techniques. This study will significantly improve the understanding toward low rice grain yield and poor rice resistance under salt stress and will also stream scientific knowledge for effective utilization of salt affected soils by using different regulating ways.

为明确基质类型及烯效唑对不同秧龄晚稻秧苗生理特征及本田期生长发育特性的影响,确定适宜晚稻机插育秧的基质类型、烯效唑浸种措施及秧龄,该研究以嘉58为供试晚稻品种,以2种代表性育秧介质(营养土和轻型无土育秧基质)为研究对象,采用2种(清水浸种和25 mg/L烯效唑浸种)外源生长调控措施,阐明了不同育秧介质和烯效唑浸种对不同秧龄晚稻秧苗生理特征、机插质量的影响及调控技术。结果表明,随晚稻秧龄延长,秧苗地上部分干物质量显著增加,叶片SPAD值和根系活力先增加后降低;水稻全生育期延长,大田生育期缩短。采用烯效唑浸种可提高秧苗素质,浸种处理秧苗茎基宽约增加0.1~0.2 mm,株高显著降低,叶片SPAD值和根系活力显著提高。短秧龄条件下烯效唑浸种对秧块质量和机插质量影响较小,长秧龄条件下烯效唑浸种可有效提高成苗率和大田基本苗数,降低漏插率和伤秧率。采用营养土育秧时最适机插秧龄为18 d,轻型无土基质育秧适宜机插秧龄为18~24 d。秧龄大于24 d时,烯效唑浸种可提高营养土育秧晚稻有效穗数和每穗粒数,增加晚稻产量,且秧龄越长,烯效唑浸种的增产效果越显著。烯效唑浸种对轻型无土基质育秧的产量影响较小。采用轻型无土育秧基质培育机插晚稻秧苗,产量高于常规营养土处理,适宜晚稻机插育秧。研究结果可为提升晚稻种植机械化水平提供重要参考。
