Design of electrode materials for stable and efficient electrocatalytic oxidation of As(Ⅲ)in arsenic-contaminated groundwater poses a great challenge due to the rapid deactivation of catalysts resulting from the high oxygen evolution potential(OEP)and considerable barrier to generating reactive oxygen species(ROS).Herein,an innovative TNAs/SnO_(2)/PEDOT/Fe(Ⅲ)-RuO_(2) multilayer electrode was synthesized by utilizing a PEDOT-coated SnO_(2) interlayer as a supportive framework to combine Fe-doped amorphous RuO_(2) catalytic layer with TiO_(2) nanotube array *** electrode exhibited high activity and sta-bility for the oxidation of As(Ⅲ)to As(V)due to the large surface area provided by the TiO_(2) nanotube arrays and the SnO_(2)/PEDOT interlayer for facilitating the growth of the catalytic *** electrochem-ically active surface area of the electrode reached as high as 31.7 mF/cm^(2).Impressively,the doping of Fe into RuO_(2) layer led to a remarkable increase in the OEP value to 3.12 V,which boosted the indirect oxidation process mediated by ROS at a lower potential to achieve the As(Ⅲ)oxidation ratio of 98.5%.DFT calculations revealed that the Fe-doped amorphous RuO_(2) weakened the adsorption strength of·OH ***4-intermediates and lowered the energy barrier for generating *** with ESR results,the formation of·OH and·SC4-with strong oxidizing properties was fully verified,providing further evi-dence for the involvement of ROS as the main mediator of the oxidation mechanism of As(Ⅲ).This work may provide valuable perspectives into the design of catalytic layer structures and heteroatom doping modifications for composite-coated electrodes.

Two pot experiments were conducted to study the effects of root pruning at the stem elongation stage on non-hydraulic root-sourced signals （nHRS）, drought tolerance and water use efficiency of winter wheat （Triticum aestivum）. The root pruning significantly reduced the root weight of wheat, but had no effect on root/shoot ratio at the two tested stages. At booting stage, specific root respiration of root pruned plants was significantly higher than those with intact roots （1.06 and 0.94 mmol g-1 s-1, respectively）. The soil water content （SWC） at which nHRS for root pruned plants appeared was higher and terminated lower than for intact root plants, the threshold range of nHRS was markedly greater for root pruned plants （61.1-44.6% field water capacity） than for intact root plants （57.9-46.1% field water capacity）. At flowering stage, while there was no significant difference in specific root respiration. The SWCs at which nHRS appeared and terminated were both higher for root pruned plants than for intact root plants. The values of chlorophyll fluorescence parameters, i.e., the effective photosystem II quantum yield （F PS II ）, the maximum photochemical efficiency of PS II （F v /F m ）, coefficient of photochemical quenching （qP）, and coefficient of non-photochemical quenching （NPQ）, in root pruned plants were significantly higher than in intact root plants, 7 d after withholding of water. Root pruned plants had significantly higher water use efficiency （WUE） than intact root plants in well-watered and medium drought soil, but not in severe drought condition. In addition, root pruning had no significant effect on grain yield in well-watered and medium drought soil, but significantly decreased grain yield in severe drought condition. In conclusion, the current study showed that root pruning significantly altered nHRS sensitivity and improved WUE of winter wheat in well-watered and medium drought soil, but lowered drought tolerance of winter wheat in severe drought soil

社交媒体时代,用户习惯于接受碎片化、同质化的信息并据此形成自己的意见或立场。一些学者认为这一现象将使得人们进入“信息茧房”或“回音室”并造成公众意见的极化,另一些则对此持反对意见。在回顾意见极化的文献基础上,本文对中国内地各地区的青年群体进行了问卷调查(N=1039),对青年意见极化的影响因素进行了分析。研究发现,社交媒体使用时间越长,社会网络异质化程度越低,青年群体越呈现出意见极化的状态。研究进一步发现并检验了选择性接触机制的中介效应,表明在青年群体的社交媒体使用过程中,选择性接触信息影响了其意见并导致极化现象的产生。
