Functional Ecology, Volume 40, Issue 11, Page 3606-3623, November 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Flowers with deep corollas are frequently associated with nectar robbing, a behaviour that often reduces pollen transfer and seed production. Robbing scars, however, may further affect plant reproductive success through rainwater entry into corolla tubes.

Resource Substitution: Local Governments' Issue Attention and Policy Reinvention
Policy Studies Journal, Volume 54, Issue 4, November 2026.ABSTRACT Research on policy reinvention, where a government modifies rather than replicates policy innovations introduced by other governments, has progressed significantly, but how it is influenced by the government's issue attention has not been thoroughly examined.

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT The deformation behavior of NiTiNb shape memory alloys is governed by microstructural heterogeneity, specifically the interconnected topology of the β‐Nb phase. The regulatory role of the eutectic structure in load partitioning and the evolution of deformation mechanisms, particularly in high‐Nb systems, has not been clearly understood.

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT The use of Ti6Al4V alloy in dental implantation is constrained by its high elastic modulus and biological inertness, which lead to delayed osseointegration and a high failure risk. Additionally, its chemical incompatibility with hydroxyapatite (HA) impedes the development of stable bioactive composites.

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 10, October 2026.ABSTRACT To achieve high‐value utilization of spent catalysts, we recovered copper (Cu) from Cu‐bearing spent catalysts via acid‐base leaching to fabricate CuO and systematically studied how calcination temperature affects their microstructure and humidity‐sensing performance. Characterizations show that CuO‐500 (calcined at 500°C) has a large specific

Boosting Decomposition and Combustion of TKX‐50 and HTPB/TKX‐50 Propellants With NH2‐MIL‐88B(Fe) MOF
Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Dihydroxylammonium 5,5′‐bistetrazole‐1,1′‐diolate (TKX‐50) is a promising energetic material that possesses both exceptional energy density and low sensitivity. Nevertheless, its application is hindered by incomplete pyrolysis during combustion or explosion. Various strategies, including eutectic formation, composite preparation, and catalysis,

, 2017 聚合物及复合材料以其优异的性能得到广泛应用。但在加工和使用过程中，不可避免地会产生微小裂纹及损伤，从而导致材料的综合性能下降并带来严重的隐患。在此背景下，聚合物及复合材料自修复性能的研究应运而生。基于Diels-Alder（DA）化学的自修复材料具有制备灵活、反应条件温和、可多次修复等特点而得到广泛研究。但是，当前基于DA化学的自修复研究工作集中于聚合物基自修复材料及其基本物性研究，而聚合物材料自身功能有限，大大限制其实际应用。同时，针对DA体系的修复方式往往局限于加热，修复时间长、效率较低。因此 ...
