The morphology of 1, 3, 5 and 7 mol% SnO2 doped titanium oxide coatings were evaluated with a scanning electron microscope (SEM), an atomic force microscope (AFM) and an UV-VIS light spectrophotometer, whilst xerogel structure was analysed with X-ray diffraction spectroscopy (XRD).
The Sn-to-Ti ratios (1, 3, 5, 7 and 10 mol% SnO2) were varied to evaluate the influence of Sn4+ on the structure, antibacterial activity against S. epidermidis and photocatalytic activity of the obtained materials.

Crystal structure variation of the nonwoven fabrics by H2 plasma treatment was also investigated.
The morphologies, the electrical conductivities with or without H2 plasma treatment, and the variation of the crystal structures of the carbon-based nonwoven fabrics by H2 plasma treatment were investigated and discussed.

The results showed that the diversity indices of aerobic methanotrophs were higher, and community structures appeared more complicated at the later plots.
The overall structure of methanotrophic communities among the different sites was analyzed by comparing profiles obtained from different samples.
So, we had concluded that the methanotrophs community structure of SF1, SF2 and SF4 was simple but the evenness was not difference in sites.

For a long-term clinical success the resin-based restorations have to assure a high resistance to different factors, including strength of the remaining tissues after caries removal [3], cavity design [5], chemical and mechanical stresses developed in the lateral zones of the oral cavity [3] and distribution of masticatory forces on the periodontal ligament (PDL)-bone structures [5].
For this purpose, the all-in-one adhesive methods have been brought on the market, as one-step technique, reducing in this way the number of procedures applied on the hard dental structures and offering the clinicians a bonding agent which is considered to be less sensitive for the application procedures [6].
The possibility to evaluate and analyze all the changes at the composite restoration level and also at adhesive-tooth structure interface, which takes place in the oral cavity, is sometimes hard to be obtained and implies higher costs, long periods of time and the ability of the researchers to conduct a well-controlled clinical trial [8].
In the given situation, the periodontal ligament act as a very thin “membrane” able to absorb all the masticatory forces [5,12] and when these reach a maximum load it is able to transmit the forces to the alveolar bone and thus, to prevent the damage of the tooth structure [12].

Introduction Nanometer size rare earth oxides have prompted wide research from their synthesis, structure and properties to their applications.
Those properties are dominated by defect chemistry.

Alternatively, the structure can be described as a layer structure, the layers consisting of Pd atoms forming four planar bonds to Se2 (S2) groups - the so-called PdS2 structure.
Besides, this effect is stronger concerning the pyrite structure.
Hence, PdSe2 is more stable under higher temperature especially in its pyrite structure.
Finally we conclude that, aiming to keep stable PdS2 structure of PdSe2 under high pressure, one should compress: (i) as fast as possible, because rapid compression impends phase transition to pyrite structure; (ii) under as low temperature as possible, as high temperature level facilitates phase transition to pyrite structure.
