Upcycling Spent Cu‐Containing Catalysts to CuO Humidity Sensors for Physiological Detection: Calcination Temperature Optimization

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

吸附苯酚活性炭微波辅助溶液再生效果

Gongye shui chuli, 2016
分析了pH对颗粒活性炭（GAC）吸附苯酚性能的影响。实验选择质量分数为1% NaOH溶液，采用微波辅助溶液再生的方法，对吸附苯酚的GAC进行再生研究，探讨实验因素对GAC再生效率的影响。实验结果表明：最佳的再生条件为微波功率520 W、再生时间1.5 min、NaOH再生辅助溶液用量10 mL，此时GAC再生效率为95.6%。在最佳再生条件下，经过6次再生后GAC的吸附能力依然很强。

Nonequilibrium Precipitation Pathway Enabling Direct δ‐phase Formation and Enhanced Cryogenic Strength–Ductility in an Additively Manufactured Multi‐Principal‐Element Alloy

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Overcoming the strength–ductility trade‐off in face‐centered cubic (FCC) multi‐principal element alloys (MPEAs), particularly at cryogenic temperatures, remains a significant challenge. Here, a laser powder bed fusion (LPBF)–enabled direct aging strategy is employed to modify the precipitation behavior in a Ni53Fe20Cr23Nb4 (at%) alloy.

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

Rare 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.

再生水厂曝气生物滤池工艺改进

Gongye shui chuli, 2008
再生水厂利用城市污水处理厂二级出水作为再生水的水源，采用二级曝气生物滤池+纤维球过滤工艺对污水处理厂二级出水进行处理，处理后出水作为再生水进行回用。由于来水水质的制约，严重影响了再生水厂的中水再生能力，通过改变再生水厂来水水源，将二级曝气生物滤池串联运行改为并联运行，提高了再生水厂的处理能力，降低再生水成本。

Biomass‐Derived Laser‐Induced Graphene: From Precursor Chemistry to Device Integration

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Laser direct writing provides a mask‐free route for converting suitable carbon‐containing precursors into patterned, porous, and conductive laser‐induced graphene (LIG) networks. Although LIG was initially demonstrated mainly using aromatic synthetic polymers, such as polyimide, biomass precursors introduce renewable feedstocks with highly ...

Lattice‐Defect‐Coordinated Microstructural Continuity and Mechanical Compatibility in LPBF‐Fabricated CoCrNi/316L Bimetallic Structures

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Bimetallic structures fabricated by laser powder bed fusion (LPBF) provide an effective strategy for achieving multifunctional integration, yet interfacial structural continuity and the role of lattice defects remain insufficiently understood.

Spatiotemporal Pattern Evolution and Driving Mechanisms of World Botanical Gardens Over Five Centuries

Integrative Conservation, Volume 5, Issue 3, Page 255-267, September 2026.
This study presents a comprehensive review of the 500‐year spatiotemporal evolution of global botanical gardens, identifying three major development stages—initial exploration (1543–1699), steady expansion (1700–1899), and rapid proliferation (1900–2020)—with six distinct sub‐stages. We propose a tripartite driving framework grounded in colonial botany
