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 ...

, 1983 所谓燃料电池是一种将物质中的化学能直接转变为电能的装置,很早以前就引起了人们的重视。本文就燃料电池在未来能源系统中的地位和作用作些概述。一、燃料电池的基本原理及特点目前我们所用的电能大部分是由火力发电厂供给。转换的途径为化学能-热-电能。热机的效率由高温热源和低温热源的温度来决定,即热效率可用η_1=(T_1-T_2)/(T_1)来计算。假设高温为400℃,低温为27℃,则η_1=(673-300)/(673)=0.539=53.9%,这是在这两个温度间理论上可以达到的最大极限 ...

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

四川大学学报. 自然科学版, 2006 从青岛近海养殖场废水样品中筛选到一株具有硝化与反硝化双重功能的细菌,命名为YZC.菌株YZC兼性厌氧,革兰氏阳性,杆状;菌落干燥、圆形隆起、边缘锯齿状,在不同培养基上菌落颜色有所变化.该菌能以硝酸钠为氮源在好氧条件下进行反硝化作用;能以乙酸钠和硫酸铵分别为碳源和氮源进行硝化作用;该菌能以乙酰铵为唯一碳源和氮源而生长,并能利用多种糖和其他碳源.我们还测定了该菌的最适pH值和其生长盐浓度,以及其水解淀粉和明胶的能力,因此,YZC菌株对自然水体,尤其是废水的生物脱氮具有潜在的研究价值.

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Spent automotive exhaust catalysts represent the largest secondary resource of palladium (Pd), and their efficient recovery is essential to support the sustainability of Pd‐related industries. Inspired by supramolecular chemistry, a novel calixarene derivative, 5,11,17,23‐tetra‐tert‐butyl‐25,27‐bis[(N′‐hydroxyacetimidamide)ethoxy]‐26,28 ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Metal–organic framework (MOF) membranes are a novel class of composite membranes. They use crystalline porous MOF materials as separation layers or functional fillers. Because of their well‐ordered and tunable pore structures and highly controllable chemical environments, MOF membranes show broad application prospects in gas separation ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Non‐noble metal oxygen electrocatalysts are essential for low‐cost rechargeable metal‐air batteries and fuel cells, determining their energy conversion efficiency. However, such electrocatalysts are limited by inadequate bifunctional activity and stability toward the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER).
