Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Lightweight and lead‐free radiation shielding materials remain urgently needed. This work designed a fluorite high‐entropy oxide (FHEO) system through a combined computational–experimental route. Density functional theory based on special quasi‐random structures was used to identify thermodynamically stable fluorites from a wide compositional ...

四川大学学报. 自然科学版, 2012 提出一种无相机标定的立体像对矫正算法,该算法只需要图像对间的匹配点信息.首先,寻找一个投影矩阵H′将右图的对极点e′映射到无穷远点,此时该图上的对极线被映射为平行于x轴的直线;然后,基于矫正后立体像对的对应极线相同的原理,推导出应用在左图上的矫正矩阵H;最后,根据得到的投影矩阵H和H′重新采样对应的图像,达到最终的矫正目的.尤其对摄像机对的角度进行分析,摄像机主轴夹角越小,对极点则离图像平面越远,矫正效果也越好.通过两种无需计算基本矩阵的非线性最优化矫正方法进行实验对比,实验结果表明,该算法实现简单 ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT High‐entropy alloys (HEAs) have attracted considerable interest from researchers owing to their tunable chemical compositions, exceptional structural stability, and promising catalytic properties. However, their large‐scale application is often hindered by complex manufacturing techniques and poor durability.

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT The development of efficient and stable bifunctional electrocatalysts is a key challenge for the industrialization of hydrogen production by water electrolysis. In this work, Co‐doped NiS/Ni3S2 heterostructured nanowire arrays (Co–NiS/Ni3S2 NA) were successfully constructed by precisely modulating the phase‐selective behavior of nickel ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT The sluggish kinetics of the oxygen reduction reaction (ORR) necessitate developing oxygen electrodes with enhanced electrocatalytic activity for practical zinc–air battery applications. In this study, an iron‐doped copper sulfide electrocatalyst (CuFeNS‐PNC) anchored on metal–organic framework‐derived carbon substrates was designed, featuring

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Sodium‐ion capacitors (SICs) offer high energy and power density with long cycle life, but developing kinetically compatible electrodes remains challenging. This work developed a simple and sustainable strategy to synthesize homologous carbon electrodes from the inner shells of durian husks (ISDH) for high‐performance SICs.

International Journal of Urban and Regional Research, Volume 50, Issue 1, Page 191-220, January 2026.Abstract Henry George advocated for capturing land value increases for public ends. The active approach of public authorities organizing and financing land development can help capture higher land value increases, as Hartman and Spit indicate. However, this approach hardly happens in developing countries, where the coalition of private developers and ...

Functional Ecology, Volume 39, Issue 9, Page 2327-2341, September 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract While elevational patterns of soil bacterial and fungal communities in mountain ecosystems have been well documented, the assembly processes of soil archaeal and protistan communities, and their linkage with ecosystem multifunctionality (EMF), remain poorly understood ...
