Enhanced Energy Storage Performances of Ceramics Enabled by Local Lattice Disorder Based on High‐Entropy Strategy

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT With the depletion of energy resources and the vigorous development of renewable energy technologies, the demand for efficient energy storage technologies has become increasingly urgent. Dielectric ceramics feature ultrafast charge–discharge speed, but low energy density and inferior efficiency hinder device miniaturization.

Competitive Anion Coordination Modulates Anode Interfacial Chemistry for Wide‐Temperature Sodium Batteries

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Sodium‐ion batteries (SIBs) offer a promising, cost‐effective alternative for large‐scale energy storage due to the abundance of sodium. However, their practical deployment is challenged by sluggish interfacial kinetics and unstable interphase formation, which severely limit performance across wide temperature ranges. Here, we demonstrate that

吸附溶出伏安法同时测定电站锅炉用水中的痕量铜、铁

open access: yesGongye shui chuli, 2008
建立了吸附溶出伏安法同时测定痕量铜、铁的方法。以邻苯二酚为配合剂,哌嗪-1,4-双(2-乙烷磺酸)(PIPES)为缓冲溶液,在最优条件下,对铜离子的测量范围为0~35μg/L,相关系数r=0.9994;对铁离子的测量范围为0~30μg/L,相关系数r=0.9980。两者的检测限分别为0.069、0.407μg/L。此法应用于电站锅炉用水中痕量铜、铁的测定,回收率分别为103.6%和104.7%。说明该法不仅灵敏度高、准确性好,而且操作简单、快速。

Electrically Switchable Altermagnetism in Monolayer MoCl3

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Altermagnets intertwine spin‐split bands with vanishing net magnetization, offering great potential for high‐density, stray‐field‐free spintronic devices. However, their development is hindered by both material scarcity and difficulties in external control due to their intrinsic symmetry protection.

Iron Ore Pricing in China: Financialization Through a Marxist Lens

open access: yesAbacus, Volume 62, Issue 3, Page 922-956, September 2026.
We offer a Marxist interpretation of financialization as we examine the Chinese market for iron ore and the shift in the pricing mechanism from an annual fixed price to an indexed price from 2010. Drawing upon Marx's theory of the circuit of capital, we illustrate an empirical case of financialization that results from the conflict between social ...
