World Water Policy, Volume 12, Issue 4, November 2026.ABSTRACT This paper describes and analyzes recharge practices in Bács‐Kiskun County, Hungary, within what can be categorized as the farmer domain. Such locally embedded aquifer recharge practices remain underexplored in Hungary. Current research and funding largely focus on large‐scale Managed Aquifer Recharge (MAR) interventions emphasizing intended ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Developing rapid, precise gas sensors for Listeria monocytogenes (LM) biomarker detection faces challenges due to suboptimal gas‐solid interactions. Herein, we report the rational synthesis of amino‐functionalized mesoporous SiO2 hollow nano‐doughnuts (MS‐2‐NH2‐2) via modification with (3‐aminopropyl) trimethoxysilane (AAPTMS), which enables ...

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Additive manufacturing of zinc‐magnesium (Zn‐Mg) alloys via laser powder bed fusion (LPBF) has gained significant recognition as a promising candidate for bone repair. However, the presence of coarse yet brittle eutectic phases in the fabricated Zn‐Mg alloys tends to induce premature stress concentration and resultant fracture during ...

Jianzhu Gangjiegou Jinzhan, 2022 为研究腹板开孔对端部约束预应力波纹钢-混凝土组合梁抗火性能的影响，采用有限元软件ABAQUS对该类组合梁在高温作用下的力学性能进行了非线性有限元分析，研究了具有端部约束预应力波纹腹板开孔组合梁的内力、跨中挠度演化过程以及破坏模式，并对其耐火性能进行了参数分析。结果表明：受约束预应力波纹腹板开孔组合梁在高温作用下的破坏模式为开孔截面腹板与端部截面波纹腹板及钢梁下翼缘发生局部屈曲；随着温度的升高，组合梁由压弯发展至拉弯的悬链线阶段；在荷载比相同、孔洞均位于剪弯区的条件下，开孔尺寸越大 ...

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT The commercialization of lithium‐sulfur batteries (LSBs) faces dual challenges of sluggish sulfur redox kinetics and lithium polysulfides (LiPSs) shuttling. Herein, we demonstrate a synergistic strategy combining multidimensional structural confinement with d‐band center modulation to simultaneously suppress LiPSs diffusion and catalyze ...

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT VO2 is a promising thermochromic material, but it is still limited by low transparency, weak solar modulation, and poor stability. Here, we develop a coordination‐compound‐derived strategy to construct a hierarchical BiVO4/VO2@BiVO4 film with a core–shell@nanosheet structure.

, 2008 开发低渗透油气田最有效的手段是改善低渗透储层物性,但目前常用的水力压裂、酸化和高能气体压裂等措施也各有其不足,因此对岩石具有应力波和爆生气体双重作用的"层内爆炸"方法应运而生。针对爆生气体作用下孔壁岩石的开裂问题,通过分析试验数据,建立了考虑试样惯性的力学模型,并从动力学角度对动态载荷作用下孔壁岩石产生多裂缝的机制做了数值模拟研究。试验及数值模拟结果表明,爆生气体动态载荷作用下孔壁岩石产生多裂缝的实质是试样对动态载荷的结构响应,孔壁岩石能否产生多裂缝主要取决于载荷、约束、结构和材料属性等因素的影响 ...
