Seawater electrolysis is an effective way to obtain hydrogen(H_(2))in a sustainable ***,the lack of electrocatalysts with high activity,stability,and selectivity for oxygen evolution reaction(OER)severely hinders the development of seawater electrolysis ***,sulfur-doped nickel-iron selenide nanosheets(S-NiFeSe_(2))were prepared by an ion-exchange strategy and served as highly active OER electrocatalyst for alkaline seawater *** overpotential is 367 m V,and it can run stably for over 50 h at 100 m A cm^(-2).Excitingly,the S-NiFeSe_(2)||Pt/C pair exhibits cell voltage of 1.54 V at 10 m A cm^(-2)under alkaline seawater conditions,which can run smoothly for 100 h without decay,and the efficiency of electricity-tohydrogen(ETH)energy conversion reaches more than 80%.Such electrode,with abundant accessible reactive sites and good corrosion resistance,is a good candidate for seawater ***,density functional theory calculations reveal that the surface sulfur atoms can activate the adjacent Ni sites and decrease the free energy changes of the associated intermediates at the adjacent Ni sites for OER,and the step of~*OH→~*O is the potential rate-limiting *** this work,the true reactive site in nickel-iron selenides is the Ni sites,but not the Fe sites as commonly believed.

The insurmountable charge transfer impedance at the Li metal/solid polymer electrolytes(SPEs)interface at room temperature as well as the ascending risk of short circuits at the operating temperature higher than the melting point,dominantly limits their applications in solid-state batteries(SSBs).Although the inorganic filler such as CeO_(2)nanoparticle content of composite solid polymer electrolytes(CSPEs)can significantly reduce the enormous charge transfer impedance at the Li metal/SPEs interface,we found that the required content of CeO_(2)nanoparticles in SPEs varies for achieving a decent interfacial charge transfer impedance and the bulk ionic conductivity in *** this regard,a sandwich-type composited solid polymer electrolyte with a 10%CeO_(2)CSPEs interlayer sandwiched between two 50%CeO_(2)CSPEs thin layers(sandwiched CSPEs)is constructed to simultaneously achieve low charge transfer impedance and superior ionic conductivity at 30℃.The sandwiched CSPEs allow for stable cycling of Li plating and stripping for 1000 h with 129 mV polarized voltage at 0.1 mA cm^(-2)and 30℃.In addition,the LiFePO_(4)/Sandwiched CSPEs/Li cell also exhibits exceptional cycle performance at 30℃and even elevated120℃without short *** multi-layered CSPEs with optimized contents of the inorganic fillers can be an efficient method for developing all solid-state PEO-based batteries with high performance at a wide range of temperatures.

【目的】为探究重金属铅与害虫取食胁迫对小白菜Brassica chinensis营养物质、防御物质和斜纹夜蛾Spodoptera litura生长发育的影响。【方法】铅胁迫(400 mg/kg)、斜纹夜蛾幼虫取食处理(取食密度:3头/叶;取食面积:30%)以及二者共同胁迫后应用生物化学方法测定小白菜(品种为正旺达88)叶片中可溶性糖含量、胰蛋白酶抑制剂含量、铅含量以及保护酶(过氧化物酶、超氧化物歧化酶和过氧化氢酶)活性,并统计了斜纹夜蛾幼虫的存活率、幼虫历期、蛹历期、羽化率和成虫干重。【结果】400 mg/kg铅胁迫与斜纹夜蛾幼虫取食的联合作用显著影响了小白菜叶片中可溶性糖、胰蛋白酶抑制剂的含量以及过氧化物酶、过氧化氢酶和超氧化物歧化酶的活性;铅胁迫、斜纹夜蛾幼虫取食及二者共同胁迫对斜纹夜蛾幼虫存活率、幼虫历期、蛹历期、羽化率和成虫干重也有显著影响。与对照组相比,铅胁迫、斜纹夜蛾幼虫取食及二者共同胁迫下,小白菜叶片中可溶性糖含量有所下降,分别降低了10.5%,9.3%和38.1%;胰蛋白酶抑制剂含量分别增加了51.6%,90.1%和103.0%;过氧化物酶活性分别增加了136.1%,46.6%和243.8%;超氧化物歧化酶活性分别增加了43.1%,16.4%和91.1%;过氧化氢酶活性分别增加了68.6%,17.3%和139.0%。铅胁迫、斜纹夜蛾幼虫取食及二者共同胁迫下,斜纹夜蛾幼虫的存活率下降,与对照相比分别降低了28.2%,31.3%和43.9%;幼虫历期与对照相比分别延长了4.28,3.78和8.41 d;蛹历期与对照相比分别延长了2.69,2.13和5.11 d;羽化率下降,与对照相比分别降低了33.4%,46.7%和60.0%;成虫干重与对照相比分别降低了7.98,3.61和12.39 mg。【结论】结果说明铅胁迫、斜纹夜蛾取食以及二者共同胁迫对小白菜生长发育产生了不利影响,植物体内积聚的重金属铅能与斜纹夜蛾介导的植物化学防御产生叠加或协同效应,诱导小白菜的抗性增强,营养物质含量下降,进一步抑制斜纹夜蛾的生长发育。
