Rare Metals, EarlyView.ABSTRACT Aqueous zinc‐ion batteries (AZIBs) hold great promise for safe and sustainable energy storage, but their commercialization is impeded by severe Zn dendrite growth and interfacial instability. To address these challenges, we propose a defect engineering strategy employing ultrafine ZnAl2O4 (ZAO) nanoparticles (∼5 nm) with oxygen vacancy defects

Rare Metals, EarlyView.ABSTRACT Dielectric ceramics are popular for energy storage materials because of their rapid charge–discharge characteristics, whereas their low energy density and efficiency hinder their miniaturization and integration. In this work, the energy storage performance is significantly enhanced through introducing Al2O3 and TiO2 into the 0.425(Bi0.5Na0.5 ...

Jianzhu Gangjiegou Jinzhan, 2020 为研究重力-抗侧力可分钢框架体系的受力性能,以某个实际工程为建筑方案,利用ETABS和PKPM软件建立了15层的重力-抗侧力可分钢框架体系和刚接钢框架体系的结构模型,在地震作用下对2种体系进行弹性和弹塑性分析。经过对比分析后得到了以下结论:在用钢量基本相同的情况下,重力-抗侧力可分钢框架体系的抗侧刚度和结构性能与刚接钢框架体系的抗侧刚度和结构性能相近;重力-抗侧力可分钢框架体系的抗弯框架受力充分,塑性铰较少,能够更好地耗散地震能量;重力-抗侧力可分钢框架体系内侧梁柱的截面较小 ...

Rare Metals, EarlyView.ABSTRACT As a promising alternative to sluggish Li2CO3‐based Li‐CO2 electrochemistry, Li2C2O4 offers a favorable 2e− discharge pathway, yet its selective formation and reversible decomposition remain debated. Herein, we propose a nonmetal‐metal synergistic catalyst—B‐Ti coregulated layered transition metal boride Ti18B18O9/graphene (B‐Ti/TiBOG)—to ...
