AFM and XRD analysis were used to characterize the crystal structure and surface morphology of these coatings.
Introduction It is well known that many methods have been developed to improve photo-activity of titanium oxide film, such as ions doping technique [1,2] and multi-layer film structure [3] to increase the generation efficiency or to reduce the re-combination probability of the photo-induced electron-hole pairs.
Results and Discussions Crystal structure and surface morphology.
Mixed TiO2-SiO2 oxide deposited at ceramic substrate obtains a continuous film structure, and it is impossible to distinguish TiO2 or SiO2 particles from this image.

A series of substituted ethyl argiosulfonylcarbamates were synthesized from substituted aromatics through three steps including chlorosulfonation, ammonolysis, nucleophilic addition and their structures were confirmed by 1H NMR and MS spectrum.
Introduction Ethyl phenylsulfonyl carbamate is a kind of important intermediate in medicinal chemistry.
The structures of those compounds were shown in Fig. 1.
Synthesis of compounds The structures and the synthetic route were shown in Scheme 1.

Using the CIS（Configuration Interaction with Single Substitute） method, and 6-31+G (d, p) basis set, we calculated the excited state structure and vibration frequency of cyclopentanone ion.
Theoretical calculations Based on the researches above, we have calculated the C5H8O+ structure of Stable geometry configuration of the excited state, as shown in figure 1.
We use C5H8O+ optimum structure as input in the coordinate and the CIS method, the 6-31+g（d, p）basis sets to calculate the configuration of different excited state vibration frequencies.

POMs are also effective photocatalysts, and their photoactivities originate from their unique structure [4].
The present study addresses the synthesis of Fe-POM fixed on a TiO2/SiO2 structured film.
The chemical structure of azo-dye CR is presented in Fig. 1.
These characteristic IR absorption data are very useful to identify the structure of POMs.

Moreover, there are magnetic materials that have a cubic spinel structure which is referred to as binary oxide or bimetal oxide materials [14].
Characterization of nanocomposite Mn0,25Fe2,75O4/NiCo2O4 Structural characterization was carried out using XRD to determine the structure, crystallinity, and size of the material.
Mn0,25Fe2,75O4 and NiCo2O4 have a cubic spinel crystal structure, so when there are composited their peak will overlap and sequentially [24].

Keywords: Neutron diffraction, Spinel structure, Cation distribution, Crystal structure Abstract.
The magnetic structure at room temperature was ferrimagnetic for the composition x = 0.0 and x = 0.2.
The spinel structure consists of a face-centered cubic lattice of oxygen ions with two types of interstitial holes for cations of tetrahedral (A) and octahedral (B) site symmetries.
The different physical properties of spinel compounds are strongly dependent on the distribution of cations within the structure.

This approach is based on the electronic structure calculations by the DV-X� molecular orbital method.
Introduction A theoretical approach to alloy design has been developed on the basis of the molecular orbital calculation of electronic structures.
For example, new structure maps have been proposed to predict the crystal structures of intermetallic compounds [9].
