Carbon‐Insertion‐Engineered WS2 Hierarchical Heterostructure Enabling Superior Sodium‐Ion Storage
Rare Metals, EarlyView.ABSTRACT Tungsten disulfide (WS2) is considered a promising anode material for sodium‐ion batteries (SIBs). However, its practical application is hindered by poor electrical conductivity, large volume changes during cycling, and sluggish ion diffusion kinetics, which lead to unsatisfactory electrochemical performance.

Jianzhu Gangjiegou Jinzhan型钢混凝土组合结构中采用超高性能混凝土（ultra-high performance concrete，UHPC）可以提高承载能力、减小截面尺寸，同时改善其因密集配置箍筋和剪力件而导致的施工复杂等问题。目前型钢UHPC组合梁有限元仿真研究主要集中在受弯性能参数化定性分析，忽略了型钢与UHPC间的黏结滑移，缺少对其界面黏结性能和组合效应的评估，对受拉区UHPC的受力性能也缺乏深度讨论。对型钢UHPC组合梁开展基于Abaqus的受弯性能有限元仿真分析，对UHPC强度、型钢强度 ...

Jianzhu Gangjiegou Jinzhan, 2011 为了研究实腹式钢骨混凝土异形柱在偏心荷载下的破坏机理、受力性能及变形能力。本文通过对12个十字形钢骨混凝土异形柱进行偏心受压承载力的试验研究,观察了含钢率和偏心距不同情况下的试件受力过程和破坏形态,分析了钢骨混凝土异形柱的荷载-位移曲线、承载力、位移延性等力学性能。通过试验,明确了钢骨混凝土异形柱的破坏特征,含钢率对承载力的影响。试验结果表明,含钢率越大,构件的承载力及延性也会相应增加,钢骨混凝土异形柱具有较高的承载能力和较好的延性。

Jianzhu Gangjiegou Jinzhan, 2005 韧性斜撑构材由主受力组件与侧撑组件组成,主受力组件承担轴力而侧撑组件则在防止主受力组件受压挫屈,由于主受力组件不挫屈,因此能充分发挥材料之强度与韧性,成为一高强度且具高消能容量之斜撑构材。以韧性斜撑构材作为同心斜撑构架中之斜撑构材,此同心斜撑构架即称之为韧性同心斜撑构架,此种构架具有稳定之迟滞行为与高韧性之特性,为一优良之耐震结构系统。本文叙述韧性斜撑构材与韧性同心斜撑构架之力学与耐震行为,并根据其力学与耐震行为提出建议之设计方法。本文为第二部分。
