Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Two‐dimensional (2D) nonlayered niobium nitrides have attracted considerable interest for electrochemical energy storage. However, the synthesis of these materials is hampered by their nonlayered crystal structures, which are characterized by strong three‐dimensional chemical bonding.

A Multifunctional Reducing Molecular Dopant for 16% Efficient Tin Perovskite Solar Cells
Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Although lead‐based photovoltaics have seen remarkable progress, tin‐based perovskite solar cells (Sn‐PSCs) continue to face challenges due to their limited power conversion efficiency and insufficient operational stability. The primary cause of this performance gap is the susceptibility of Sn2+ to oxidation, which promotes rapid defect ...

Shiyou jixie, 2012 气举采油作业中，气举阀流量与采油效率、成本紧密相关，是确定采油工艺的关键因素，因此了解其流量特性十分必要。气举阀可伸缩的阀杆总成与阀腔内气体流场的交互作用，使其流量不仅与进出口压力相关，而且与阀杆行程相关，这样的流量求解问题具有流固耦合特性，采用单纯的固体力学方法或流体力学方法均难以求解。通过对Fluent软件开放的用户自定义函数UDF的二次开发，研究出在任意进、出口压力条件下气举阀流量的计算方法。该方法应用于某型号1 in气举阀，得到合理的阀杆行程，重现了气举阀的“流量堵塞”现象 ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Chemically self‐charging aqueous zinc‐ion batteries (AZIBs) have emerged as promising candidates for energy storage technologies owing to their environmental autonomy and structural simplicity. Nonetheless, the self‐charging performance is significantly compromised by the limited potential difference between cathodes and oxygen, as well as the

Governance of Climate‐Induced Relocation in the US: An Exploration of Institutional Complexity
Review of Policy Research, Volume 43, Issue 2, March 2026.ABSTRACT Climate change has and will continue to have a profound effect on both individuals and the communities in which they reside. A pressing question is how communities forced to confront climate‐induced catastrophe—including both rapid and slow‐onset hazards—undertake the decision of how and when to relocate, particularly given the multiple scales
