The human immune system is composed of a distributed network of cells circulating throughout the body, which must dynamically form physical associations and communicate using interactions between their cell-surface proteomes1. Despite their therapeutic p
Using a CuInSe 2 /Cu 4 RbCl 5 /Cu solid state galvanic cell, we have studied the insertion and extraction of Cu in the host lattice of CuInSe 2 . This allows to present the first experimental measurements of the formation energies of Cu-related point defects. Preliminary experiments on Cu...
It uses theaverage number control diagramon the basis of measuring the acid value of higher polymer by electronic titration, so that the analytical quality is ensured during the measuring process. 提出用均数控制图来评价分析结果的可靠性方法。
Electronic configuration is defined as the distribution of electrons into the orbitals of an atom. Every neutral atom consists of a fixed number of electrons which is equal to the number of protons and is called the atomic number. Apart from electrons and protons, an atom also has neutrons whi...
Titration/Volumetric AnalysisA new method to determine a ternary phase diagram of benzene-acetic acid-water system is provided to upperdivision undergraduate students. The partially miscible liquid phase region can be accurately constructed using isothermal titration microcalorimetry (ITC). Compared with ...
