Introduction The application technology of material genome will start with the most basic composition of micro atoms, electrons, ions and energy bands, study the crystal structure, electronic structure and diffusivity of the matrix, second phase and interface of the material, and predict the mechanical, conductive and thermodynamic properties of the characteristic microstructure.
Calculation and Analysis Method This project takes first principle molecular dynamics as the core simulation method and adopts Matcloud cloud computing simulation platform to calculate the stable structure in reciprocal space and analyze its density of States and energy band structure.
The crystal structures of poscor 30 and poscor 31 have high electron area density, and poscor 0, poscor 7, poscor 12 and poscor 19 have low area charge density.
In terms of theoretical research, the microstructure, electronic structure, bonding type and strength of the alloy are changed by alloying and microalloying.

In this paper we have developed phospha sugar chemistry starting from phosphorus heterocyclic compounds, e.g., 2-phospholene derivatives [3,4].
To make the MRI contrast agent remain in the blood vessels so as to image the clearer blood vessels (Magnetic Resonance Angiography (MRA)) and tumours, the sugar ball dendritic structure of the Gd-DTPA complexes were designated and synthesized (Scheme 1 exemplifies Gd-DTPA-D1-Glc(OAc) (four peracetylated glucose derivative)) [1,2].
