Rare Metals, EarlyView.ABSTRACT Converting CO2 to CH4 under mild conditions is a promising strategy for solving environmental and energy problems, but also a challenge. In this work, the low‐temperature CO2 hydrogenation process over Ni/CeO2 catalysts was significantly accelerated by optimizing the H2 dissociation ability of Ni through the size effect, thus A‐Ni/CeO2 with an

Shuitu Baochi Xuebao, 2000 研究结果表明，湖南几种常见的菜园土壤对铅的吸持量大小顺序为：红灰菜园土〉紫泥菜园土〉黄沙菜园土〉红菜园土。后３种土壤对铅的吸持过程均可用Ｌａｎｇｍｕｉｒ、Ｆｒｅｕｎｄｌｉｓｈ和Ｔｅｍｋｉｎ方程来描述；红菜园土和黄沙菜园土的最大吸持量是５５８８．８８ｍｇ／ｋｇ和８５１６．４６ｍｇ／ｋｇ；除红灰菜园土以外，另外３种土壤的解吸量及解吸率都随吸持铅量的增大而大。

Rare Metals, EarlyView.ABSTRACT Early detection of thermal runaway (TR) is essential for lithium‐ion battery (LIB) safety, as unchecked TR risks catastrophic failures in energy storage systems. Gas‐based sensing offers a faster and more direct approach by detecting decomposition products at the molecular level.

Optimizing CuO on 3D Ordered Macroporous CeO2 for CO Oxidation in Rich Hydrogen
Rare Metals, EarlyView.ABSTRACT CO preferential oxidation (CO‐PROX) in rich H2 is considered a feasible strategy to solve CO poisoning for fuel cells, but obtaining good activity at low temperatures is still a challenge. Herein, three‐dimensional ordered macroporous (3DOM) CuO/CeO2 catalysts were fabricated by a templating approach, with the metal–support interaction (MSI ...

A Green Synthesis of Silver Gel Using Tannic Acid , its Characterization and Antibacterial Activity [PDF]
, 2015 摘要 研究目的： 纳米银的绿色合成是近年来纳米材料研究的热点之一，现有关于纳米银的制备方法和抗菌性能研究尚缺乏统一标准。单宁酸制备纳米银凝胶是一种简便高效的方法，但其抗菌性能优劣和能否将其应用于临床治疗，国内外未见相关报道。本实验采用一种简便高效的方法制备出稳定性好和粒径均匀的单宁酸银凝胶，并对单宁酸银凝胶进行多种表征分析。在表征单宁酸银相关化学结构性质的基础上，制备出三组不同数量级别的单宁酸银抗菌凝胶，采用MTT法对其进行抗菌性能测定，优化出抗菌最佳浓度，探讨了单宁酸银凝胶对四种不同细菌的抗菌效果 ...

Rare Metals, EarlyView.ABSTRACT Low conductivity, slow ion‐diffusion, and limited reactive sites are common problems in electrocatalysts and electrode materials. In this study, a complex NiTe–CoTe heterojunction with abundant Te vacancies embedded in N, P, and F co‐doped hollow carbon nanorods (NiTe1−x–CoTe1−x/NPFC) was fabricated via a simple ionic liquid‐assisted ...
