The Size, structure,
appearance, the light absorption and hydroscopicity properties were characterized by XRD, TEM,
UV-Vis and FTIR.
On the other hand, the possibility of carrying out selective photooxidations in nonaqueous media is very interesting in the context of Green Chemistry [3].
The present piece of research is aimed at exploring the effect of the presence of iron on the structure and photocatalytic activity of titania-based catalyst.
From Fig.1 and Fig.2, it can be found that Fe doping almost has no influences on the crystal structure and morphology of the obtained samples.

The structure were analyzed by X-ray diffraction (XRD), scanning electron microscopy( SEM).
SnO2 thin films have been produced by many methods, including magnetron sputtering, RF-sputtering, metal organic decomposition, ultrasonic spray pyrolysis, thermal oxidation, pulsed laser deposition, atmospheric pressure chemistry vapour deposition (APCVD) , sol–gel and so on.
Among the factors which influence film structure, substrate is the most important one.
Because the films structure correlated with the incipient course of deposition.
(2) Surface roughness has a biggish effect on the structure of SnO2 films,too.

Such materials can be produced in the form of coatings and successfully applied for maximizing the damping of mechanical and structural vibrations or for limiting the damage effects of impact events on structures and components.
Introduction As frequently reported in the literature, the chemistry of urethanes coating technology distinguishes the use of these three materials: polyurethanes, polyurea and hybrid polyurethane- polyurea products.
The main difference in the chemistry of these materials stands on the combination of an isocynate component with amine terminated resins (-NH2) rather than hydroxyl (-OH) terminated as can be found in polyurethanes families.
The design and development of new engineered materials is a key aspect for improving the performance and safety of existing structures.

This problem has been solved in the case of
magnetoplastic effects (MPEs) related to change in the structure of point defect clusters in ionic
crystals.
Thus there is reasonable to expect change of atomic structure caused by switching of the cluster spin state under MF.
It is well known from the spin chemistry that several parallel reaction channels are necessary to observe spin-dependent magnetic effects.
Partially experience of studying of these reactions could be taken from spin chemistry.
Strong deviation of physics of spin-dependent phenomena in the lattice from spin chemistry reactions in liquids is expected.

The objective of this study was to develop an anodization process using a toxicant-free electrolyte to modulate nano-scale surface features and surface chemistry on Mg.
It was observed that the nucleating oxide structures of A-Mg0.5 became homogenized in AA-Mg0.5 (Fig. 4b).
Surface cracks were observed in the nano-structure of AA-Mg2, indicative of defects in the anodically generated layer.
Additional studies are necessary to elucidate the crystal structure and stoichiometry of surface compounds.
