  • databases - How can I get xyz coordinates of atoms of a unit cell . . .
    Go to Calculate → Packing Slicing… and under Packing area tick Pack option, and under Include Atoms area select … that Fit Now you have the content of the entire unit cell: Save the data as XYZ by clicking File → Save As… → Save as type: XMol files (* xyz) This produces a file with the coordinates of all atoms of the unit cell
  • 如何快速查询Nature Chemistry文献 - 百度经验
    Nature Chemistry是一个专门发表介绍化学所有领域最重要、最尖端研究工作的高质量论文的月刊,是Nature的子刊。化学工作者经常需要查询Nature Chemistry的文献。如何在谷歌学术不能用、外网访问太慢、百度太渣的情况下,快速查询到Nature Chemistry的文献呢?今天给大家分享一个快速查询Nature Chemistry文献
  • theoretical chemistry - What are observationally stable elements . . .
    Theoretical calculations predicts some stable isotopes like calcium-40 to be radioactive But nobody has ever measured that this isotope emits a radiation It may be assumed that the half-life of this isotope is so large that not even one Ca-40 atom is destroyed in any sample of this element during one life (~100 y) So the Ca-40 isotope is considered as "observationally stable" Another
  • 已知ksp如何求溶解度-百度经验
    设溶解度为xmol L,然后用它表达各离子浓度,乘起来等于Ksp。 主要信息: 溶解度,符号S,在一定温度下,某固态物质在100g溶剂中达到饱和状态时所溶解的溶质的质量,叫做这种物质在这种溶剂中的溶解度。 物质的溶解度属于物理性质。
  • 如何评价化学咨询平台x-mol? - 知乎
    注册账号后,可以选择关注期刊和关键词(最多10个),这样基本上每周他都会给你邮件推送你关注的这些期刊里面与关键词相关的文献,这样就不用一个一个期刊的定期去浏览,感觉也比直接在每个期刊都RSS订阅省事,毕竟那样会受到很多封邮件,而xmol一封
  • pH notation in text - Chemistry Stack Exchange
    When referring to units of pH in continuous text (i e not in a table), which is the recommended usage? pH 7 to pH 8 pH 7 to 8 What about when the term "pH" has already been mentioned in the text?
