Here, we show a universal relation between electron density minima and ionic radii, which was discovered from the first principles calculations of electronic structures in metal oxides over 50 species.
DV-X� � � � Molecular Orbital Method and Cluster Models A series of electronic structure calculations was performed using the DV-X� molecular orbital method [4-7].
For the calculation a large-size cluster model was constructed using experimental data on the crystal structure of oxides.
For example, it was a Mg32O32 cluster for MgO with the rock salt structure, and a Ti7Ba8O36 cluster for BaTiO3 with the perovskite-type structure.
It is surprising that every oxides falls on one curve, despite the difference in the crystal structures among them.

CS is a basic polymer of helix structure with reactive amine groups, which gives a lot of possibilities for modification and ionic interactions [4].
In this paper, their structures were characterized and their properties were also evaluated.
The peak between 101 and 50 ppm were attributed to the carbon on the chitosan structure in the 13C NMR [5].
In the other 13C and 1H NMR the structure of the carboxylic acids could be displayed.
The XRD showed that the crystalline structure of CCS was different to CS.

The effect of bentonite (BT) on the structure and performance of sodium alginate (SA) as microsphere carrier of essential oil is studied.
The hydrogen bonding between SA and BT is shown in FTIR, and the interlayer spacing of BT crystal structure is not changed in XRD analysis.
The more dense structure of SA/BT microspheres than that of SA microspheres is confirmed by SEM.
This can be explained that the increase of temperature can affect the arrangement of molecules and depolymerize the functional segments of double helix structure formed in SA of some sugar units with the same structure, resulting in the decrease of viscosity.
SA/BT microspheres have a denser and more compact surface structure compared with SA microspheres in the 500 and 2000 times figures The more compact network structure plays a better role in the controlled release of CEO.

From Avrami theory perspective, the growth forms of geopolymer in the geopolymerization process exhibit two and three dimensional structure with the presence of secondary nucleation. 1.
Introduction Geopolymer is one of the types of binders that is available and used in structural materials in the world due to its simplicity in operation, easy availability, low cost of ingredients as well as strong in structure [1].

XRD results indicated the crystalline structure of Mg doped ZnO nanorods films where the peak intensity of ZnO was decreased as annealing temperature increases.
These indicated that possibility of mg replaced Zn lattice sites in ZnO lattice [8] which to reduce the crystallinity and hexagonal structure of the thin films [11].
