In this study, de novo phasing was required—not because of the absence of homologous structures, but because none of those available were sufficiently close to serve as a search model for molecular replacement. Using Tb-Xo4, a caged terbium compound, we could phase theBtiCry11Aa structure by...
The structure of Sr(Aet)2-8H2O is fully studied; the crystals of the compound are composed of the complex centrosymmetric dimeric [(H2O)5Sr(Aet)2Sr(OH2)5]2 cations, (Aet)- anions, and water molecules; the independent part of the structural formula of the compou...

Normal human primary hepatocytes (Liver) were purchased from the Dalian Institute of Physical Chemistry (Dalian, China). Liver was cut into small pieces and digested with the appropriate amount of 0.25% trypsin at 37 °C for 2–3 min. Observed under the microscope, these cells tended to...
While studying chemistry at university, Wang Yixi often came across an experimental preparation process that he had to explain, but the amount of text was too large and abstract. As she had been interested in drawing,...

In the study of chemical reactions, chemistry students first study reactions that go to completion. Inherent in these familiar problems—such as calculation of theoretical yield, limiting reactant, and percent yield—is the assumption that the reaction can consume all of one or more reactants to...
