采用化学共沉淀法成功制备了磁性埃洛石,运用扫描电子显微镜(SEM)、红外光谱仪(FT⁃IR)、X 射线衍射仪(XRD)和振动样品磁强计 (VSM)等手段详细表征了改性前后埃洛石的结构和形态,并采用静态批量平衡法对Co(Ⅱ)在磁性埃洛石上的吸附行为和机理进行探究,考察 了料液比、平衡时间、pH 值和温度等因素对吸附的影响.实验结果表明:温度为 50 ℃ 时,Co(Ⅱ) 在磁性埃洛石上...
Magnetic, electrical and magnetodielectric properties have been studied in Co-Ti co-doped M-type hexaferrite BaCo x Ti x Fe12-2x O19 (x = 0 65 4). With the incorporation of Co-Ti, both their ferromagn...
采用CO和NO作为探针分子,应用原位红外光谱法(in-situ FT-IR)和程序升温还原(H2-TPR)对Mo/γ-Al2O3和Co-Mo/γ-Al2O3加氢催化剂进行表征,并对催化剂进行了加氢脱硫(HDS)活性评价。实验结果表明,在Co-Mo/γ-Al2O3催化剂表面存在三个吸附位;在Mo/γ-Al2O3催化剂中加入助剂钴对钼吸附位起到显著的改性作用,并且引入新的活性中心,提高了催化剂的催化活...
采用磁控溅射法在Si(100)基底上镀制了膜系结构分别为[Mg/Co]20、[Mg/SiC]20的两组多层膜,以研究Mg基多层膜的稳定性。对放置在室温和80%相对湿度环境下的样品进行显微镜、表面粗糙度和X射线掠入射反射率测试,对比研究了Mg/Co和Mg/SiC两种多层膜结构在相同环境中的损坏状况。对比结果显示:放置4天后,Mg/SiC损坏面积为26.34%,表面粗糙度为10 nm;Mg/Co的损坏...
为改善H13热作模具钢表面的热磨损性能,利用6kW横流CO2激光器制备了Co50熔覆层和不同成分配比的Co/TiC复合涂层。借助X射线衍射(XRD),扫描电子显微镜(SEM),显微硬度计和高温摩擦磨损试验机分析了涂层的结合特征,物相组成和不同温度下的摩擦磨损性能。结果表明,当预置层粉末中TiC含量(wt.%)小于等于20%时,熔覆层与H13钢基材呈良好的冶金结合,随着TiC含量的增加,涂层中基体相...
In the superconductor LaRu$_3$Si$_2$ with the Kagome lattice of Ru, we have successfully doped the Ru with Fe and Co atoms. Contrasting behaviors of suppression to superconductivity is discovered betw...
The anomalous magnetoresistance effect in compositionally modulated TM/TM films (Co/Pt and Co/Pd) has been investigated. Results of measurements on samples at room temperature as a function of the str...
Four previously known rotational bands in 76Rb have been extended to moderate spins using the Gammasphere and Microball gamma ray and charged particle detector arrays and the 40Ca(40Ca,3pn) reaction a...
Many networks are complex dynamical systems, where both attributes of nodes and topology of the network(link structure) can change with time. We propose a model of co-evolving networks where both nod...
We investigate how author name homonymy distorts clustered large-scale co-author networks, and present a simple, e ective, scal-able and generalizable algorithm to ameliorate such distortions. We eval...
