Electrochemical production of hydrogen peroxide(H_(2)O_(2))via the two-electron(2e-)pathway of oxygen reduction reaction(ORR)supplies an auspicious alternative to the current industrial anthraquinone ***,it still lacks efficient electrocatalysts to achieve high ORR activity together with 2e-selectivity ***,a boron-doped defective nanocarbon(B-DC)electrocatalyst is synthesized by using fullerene frameworks as the precursor and boric oxide as the boron *** obtained B-DC materials have a hierarchical porous structure,befitting boron dopants,and abundant topological pentagon defects,exhibiting a high ORR onset potential of 0.78 V and a dominated 2e-selectivity(over 95%).Remarkably,when B-DC electrocatalyst is employed in a real device,it achieves a high H_(2)O_(2) yield rate(247 mg·L^(-1)·h^(-1)),quantitative Faraday efficiency(~100%),and ultrafast organic pollutant degradation *** theoretical calculation reveals that the synergistic effect of topological pentagon defects and the incorporation of boron dopants promote the activation of the O_(2) molecule and facilitates the desorption of oxygen *** finding will be very helpful for the comprehension of the synergistic effect of topological defects and heteroatom dopants for boosting the electrocatalytic performance of nanocarbon toward H_(2)O_(2) production.

机场建设是航空业运行的关键,一般机场都会配置变电站用于供电,将空调处理设备、水处理设备安装在能源中心,设置专门监控程序管理机场常规能源,如水、电、冷等能源.在以往机场运行过程中,运营单位常用不同系统独立组网,实施集中监控管理模式,导致机场管理方式对能耗和负荷变化掌握程度过于片面,难以根据功能和用能特征制定合理的管理方法.基于此,本文就上述问题,对杭州机场动力机电与能源管理系统展开论述.

皖南泾县地区新发现的两份民国初年禁赌文约手稿内容丰富,涉及当地清末民初赌博的现象及其原因,以及当地宗族应对的措施。晚清民国时期社会风尚的转变便利了赌博的兴起,外来游民、当地不务正业之人以及内外勾结之人是造成赌风大盛的重要推手。赌风大盛,导致百姓废时失业,荒废农时,更有甚者导致涉赌者倾家荡产,进而与盗匪勾结,严重危害当地基层社会稳定。宗族和官府采取订立禁赌文约、设置禁赌碑刻、颁布禁赌告示等禁赌措施抑制赌风蔓延。两份文约手稿与皖南其他方志、家谱、碑刻、告示相印证,体现当地士绅为防治赌风做出的应对措施。当地宗族的惩戒措施主要为罚钱罚酒,重“戒”轻“罚”,强调了基层社会治理中“德”与“法”的有机结合。
