【纳米】氮掺杂石墨烯包覆钴纳米核壳结构的双功能催化性能研究及其在锌空电池上的应用。外层石墨烯如同“铠甲”般阻断了活性金属纳米粒子催化剂与苛刻反应环境（如强酸，强碱和强氧化性等）的直接接触，从而有效地提高催化剂的稳定性。该工作在原有石墨烯包覆过渡金属核壳催化剂的研究基础上，对核壳结构的形成过程、析氢和析氧双功能的催化活... 阅160 转3 评0 公众公开 17-04-24 14:32 |
好话不说第二遍——论文写作中的重述语意。O-vacancy-rich/-poor 5-atom-thick In2O3 porous sheets--> a perfect 5-atom-thick In2O3 slab and oxygen-defect 5-atom-thick In2O3 slab with O-vacancies.如果感兴趣的话可以留言，我们下一期可以以这一篇论文为例，具体分析如何重述语意，为什么要这样重述语意。 阅135 转1 评0 公众公开 17-04-17 08:09 |
Part 1. 详细描述样品有着怎样的形貌。实例三：The scanning electron microscopy (SEM) images of both ZnO films also showed essentially the same smooth surface morphology composing of closely packed particles with a particle size of 30?50 nm, indicating that each particle was a ZnO single crystal since this particle size ... 阅1433 转15 评0 公众公开 17-04-17 08:08 |
XRD谱图作为定性分析手段。SCI论文中怎样描述XRD结果？2）下文其它表征需要和XRD结果进行呼应时，比如HRTEM图片中的晶面间距要和XRD (h,k,l)面进行对应时；（3）有多个XRD谱图需要描述时，第一个谱图的描述宜详写，这样后面的谱图描述就可以简略一些，详略得当。适用于：1）材料组成简单且比较明确的情况下，XRD谱图只是用来区别物质组成时；2... 阅942 转13 评0 公众公开 17-04-17 08:08 |
Fig. 2 illustrates the N2 adsorption–desorption isotherms and BJH pore size distribution plots (insert) determined from the adsorption branch of the N2 isotherms for the calcined silicas and carbon replicas. The values of the BET surface area, total pore volume, pore diameter, and wall thickness are listed in Table 1... 阅66 转1 评0 公众公开 17-04-17 08:08 |
SCI论文中如何描述XPS实验结果？定性分析结果：The coexistence of 元素化合态(I) and 元素化合态(II) in 样品名 catalyst is evidenced by a shoulder observed on the main peak at 峰位置 eV (Figure2a), which is assigned to 物种类型 species. The higher binding energy (BE) 峰属性 peak at峰位置eV and its shakeup satellites are du... 阅2230 转33 评0 公众公开 17-04-17 08:07 |
SCI论文写作中一些常用的句型总结(一)F. An interesting approach in the use of zeolite as a water-tolerant solid acid was described by Ogawa et al（Chem.Rev. 2002, 102, 3641?3666）B. This is consistent with the observation from SEM–EDS. (Z.Zou et al. / Chemical Physics Letters 332 (2000) 271–277)D. The results are in ... 阅72 转0 评0 公众公开 17-04-17 08:07 |
