Metal sulfides with high theoretical capacities are expected as promising cathode materials of Al batteries(AIBs). However, powdery active materials are mainly synthesized and loaded on current collector by insulating binder without capacity. Meanwhile, S as inert element in metal sulfides can not usually provide capacity. So, powdery metal sulfides only exhibit limiting practical capacity and poor cycling stability due to weak conductivity and low mass utilization. Herein, the novel self-supporting and dual-active Co-S nanosheets on carbon cloth (i.e. Co-S/CC) with hierarchically porous structure are constructed as cathode of AIBs. Co-S nanosheets are derived from ZIF-67 nanosheets on CC by a facile ligand replacement reaction. As a result, the binder-free Co-S/CC cathode with good conductivity delivers excellent initial discharge capacity of 383.4 m Ah g^(-1)(0.211 m Ah cm^(-2)) at current density of 200 m A g^(-1)and maintain reversible capacity of 156.9 m Ah g^(-1)(0.086 m Ah cm^(-2)) with Coulombic efficiency of 95.8% after 500 cycles,which are much higher than those of the traditional slurry-coating cathodes. Both Co and S as active elements in Co-S/CC contribute to capacity, which leads to a high mass utilization. This work provides a significant strategy for the construction of self-supporting metallic cathode for advanced high-energy density Al battery.

美国著名科幻作家威廉·吉布森的代表作《神经漫游者》以反乌托邦的手法,描绘了赛博空间权力压迫下的人类所面临的生存困境。小说中的主权者在“例外状态”的赛博空间,通过空间隔离、法律悬置、技术操控等方式剥夺人类生命权,最终将人类一步步推向“赤裸”的深渊。小说呈现了一个充斥着隐性暴力与权力压迫的赛博空间并折射了后人类时代的生命政治逻辑:当网络与技术成为权力工具,人类将沦为“赤裸生命”。而生命权力的压迫也必将引发神圣人的曲线抵抗。小说揭示作者对赛博时代生命权力沦丧的批判,以及对后人类生存境遇的深层关怀与伦理反思。

为分析周边建筑物对目标建筑物顶面风流场特性的影响,以内蒙古工业大学学生宿舍为目标建筑物,并以其为中心,分别对五种不同半径范围内的周边建筑物进行模拟计算,分析盛行和非盛行风向下五种几何模型中目标建筑物顶面的风场特征,结果表明,所考虑周边建筑物的范围尺寸对目标建筑物顶面风场特征影响较大,随着考虑周边建筑物范围尺寸的扩大,目标建筑物顶面的减速现象越明显,且强湍流区域越大。由于不同尺寸范围内周边建筑形态、布局、高度等差异,仅考虑盛行风向不能准确判断目标建筑周围风场特征,需根据周边建筑的结构和分布特征对多个风向情况进行分析。
