Emerging MBenes for Energy Technologies
ABSTRACT The escalating global demand for sustainable energy is driving the search for transformative materials that transcend the limitations of conventional systems. Two‐dimensional (2D) transition metal borides (MBenes) have recently emerged as a compelling class, distinguished by unique electronic structures, tunable surface chemistry, and ...

ABSTRACT Dielectric polymers commonly suffer from severe performance degradation above 150°C, hindering advanced power systems. Herein, we demonstrate a polyetherimide (PEI) nanocomposite that overcomes this by mimicking the gradient architecture of nacre and bamboo, incorporating a continuous vertical gradient of fluorinated boron nitride nanosheets ...

广东电网遭台风泰利侵袭的输配电设备受损分析及评估 [PDF]
近年来致灾台风频率呈增加趋势,以2023年影响广东电网约百万用户的第4号台风“泰利”为例,分析广东电网遭台风侵袭受灾情况,建立输配电杆塔受损预测模型,识别关键特征变量与因素,为电网防灾减灾提供支持。首先,分析台风“泰利”气象特征,具有“台前对流活跃,风力强度大,降水范围广”等特点,对输配电设备均产生一定程度破坏。其次,利用随机森林、支持向量机、梯度决策树、神经网络等4种机器学习算法建立输配电杆塔受损预测模型,并对比部分算法针对不平衡样本优化前后模型表现。算例表明,随机森林优化后提升最大 ...

采用“电化学氧化-电渗析”联合处理丙烯腈四效蒸发凝液,既解决了电化学氧化出水盐含量高,不利于后续生化处理的难题,又节约了运行成本。结果表明,三维电化学氧化效果明显优于二维电化学氧化,多种有机污染物被大幅去除,三维电化学氧化出水中总氮(TN)和总有机碳(TOC)质量浓度分别降至125.8、335.2 mg/L,比二维电化学氧化分别降低了18.36%、26.31%,运行能耗也降低了14.4%;采用电渗析处理氧化出水,脱盐率接近100%,且浓水回用对污染物的去除率影响较小,最终出水B/C提升至0.43 ...

ABSTRACT Aqueous zinc‐ion batteries (AZIBs) have attracted increasing attention in energy storage owing to their high energy density, low redox potential, and cost‐effectiveness. Nevertheless, uncontrolled dendrite accumulation, gas generation, and severe side‐reaction problems hinder the cycling lifespan, which prevents their commercial applications ...

ABSTRACT Achieving a simultaneous enhancement in both tribological and mechanical properties of self‐lubricating composites has long been a challenge. In this study, we designed the composition based on first‐principles calculation and fabricated a copper‐based self‐lubricating composite with excellent tribological and mechanical properties via spark ...
