Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT The development of lightweight, high‐attenuation, and broadband carbon‐based electromagnetic wave absorbers is hindered by the intrinsic trade‐off between impedance matching and dielectric dissipation. Herein, we report a facile and scalable synthesis of N‐doped lignin‐derived interconnected porous carbon (Nx‐LIPC) via hydrogen‐bond self ...

Jianzhu Gangjiegou Jinzhan, 2005 扇形焊接开孔为进行梁翼板全渗透开槽焊接时所需之工作孔。然而,实尺寸梁柱接头试验证实,传统梁腹板锁螺栓及梁翼板全渗透焊接之钢构造梁柱接头,常于扇形开孔处发生突然性之脆性破坏。本研究采用非线性有限元素分析方法,探讨扇形焊接开孔于钢骨梁柱接头耐震行为上之影响,包括扇形开孔几何形状对接头区力学行为之影响。分析结果显示,平顺接至梁翼板之扇形开孔能将最大塑性应变之发生位置移离扇形开孔根部,减少因几何形状不连续所造成之应力集中现象,降低局部区域之韧性需求;无扇形开孔之梁柱接头可避免有扇形开孔之缺陷 ...

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT The development of structurally stable anodes with high capacities and long cycle lives is essential for the development of potassium–ion batteries. Conversion‐type anodes have attracted considerable attention in potassium–ion batteries (PIBs) due to their high theoretical capacities.

Dizhen xuebao, 2018 2014年以来，滇南地区高大、开远和易门3口井的井水位出现趋势上升现象。通过开展井孔周边地下水开采情况的调查、降水影响的定量排除、井孔含水层系统应力状态的定量计算、周边区域构造活动的分析以及井孔水体化学组分的分析等工作，认为易门井的水位年动态主要受控于降水，2003年以来的趋势下降和2014年的趋势转折上升与大椿树工业园区的深井开挖抽水密切相关；高大井和开远井的井水位自2014年以来的趋势转折上升现象不完全受控于降水，但与周边地下水的开采亦无直接联系，可能与近几年该区域南北向强挤压为主的构造活动有关。

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Nickel oxide (NiO)‐based electrodes with high theoretical specific capacitance can effectively increase the energy density of supercapacitors—the key factor limiting their practical deployment. However, several issues still restrict the production of advanced NiO‐based electrodes.

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The precise quantification of cytokines is crucial for monitoring disease onset and progression. Herein, we developed a synergistic signal amplification approach by utilizing nanoreactor‐encapsulated CeO2 nanozymes, which were in situ electrodeposited within the mesoporous silica nanochannel film (SNF) grown on indium tin oxide (ITO ...

Shuitu Baochi Xuebao, 2020 为研究蒸发阶段不同覆膜开孔条件下土壤水分运动，在室内进行蒸发模拟试验的基础上，采用HYDRUS-1D模型对不同覆膜开孔率和大气蒸发能力条件下土壤剖面含水率和潜水蒸发量动态变化进行了模拟，并与实测资料进行比较。结果表明：土壤剖面含水率同时受大气蒸发能力和覆膜开孔率的共同作用，随覆膜开孔率和大气蒸发能力的增加，土壤剖面含水率减小，且上层土壤含水率差异比下层土壤明显；覆膜开孔率和大气蒸发能力-定时，土壤剖面含水率在蒸发初期有所增加，蒸发后期基本保持稳定；覆膜对潜水蒸发的阻滞作用明显，但开孔率增加到-定数值时 ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Environmental pollution across water, air, and soil systems poses escalating threats to human health and ecosystem stability, driven by heavy metals, persistent organic pollutants, particulate matter (PM), bioaerosols, and toxic gases. Conventional remediation technologies often suffer from limited selectivity, insufficient efficiency, and the
