The morphology, composition and structure of ALD-deposited oxide thin films were investigated.
The structure of deposited thin films on varied substrates was examined by x-ray diffraction (XRD, D8 ADVANCE from BRUKER).
Structure of deposited nano thin films by XRD All of the ALD-deposited oxide thin films on silicon substrate in this study are amorphous structure according to XRD analysis, shown in Table 1.
The amorphous structure of all samples probably resulted from low deposition temperature, high aluminum content and thin thickness.

Abstract.
The surface chemistry of the coated films was studied by taking ATR-IR measurements, and the wetting behavior was characterised by contact angle measurement Introduction.
Basically, Tiron is employed as a titrimetric indicator and to form chelate ring structures with titania, zirconia, alumina, tin oxide leading to strong adsorption with the surface [11,12].

Abstract.
The as-synthesized oxynitride powder contains only Ti0.6Cr0.4OxNy with cubic structure.
Structures and properties of oxynitrides containing one transition metal have been comparatively studied, whereas less are known about systems including two or more metals [2].
The as-synthesized powder contains only Ti0.6Cr0.4OxNy phase with cubic structure, and no impurities such as CrN, Cr2N and TiN phases were detected by XRD analysis.

Abstract.
A room temperature route for doping silica particles with Cu nanoparticles to achieve hybrid structures is introduced.
Hybrid or core-shell structures have been intensively studied very recently, in particular since such structures exhibit peculiar properties which make them attractive for applications in optical and biological sensors and in optoelectronics [6].
In all coating methods, the monolayer cover is important, as the chemistry is specific to the shell.
