A strong argument for using the Sol-Gel chemistry is found in the high flexibility of the method and the large choice of commercially available "dopants" that can be incorporated in the solid matrices, that might have a specific activity or reactivity to an external signal (i.e. light, magnetic, electrical, etc).
The rapidly developing sol-gel process has been used for the preparation of materials for a wide range of fields, adapting the chemistry and the novel synthetic routes to the specific systems, in order to achieve complicated developments oriented to nanotechnology applications.
Introduction In the last 20 years, the Sol-Gel chemistry has gained a large number of researchers, which developed interesting and sophisticated novel synthetic methods, offering a variety of approaches to new systems preparation, overcoming many of the synthesis difficulties of the past.

However, the surface chemistry of these polyesters does not fully promote cell adhesion and proliferation due to its hydrophobic nature [3].
The spectrum of SF in Fig. 1(a) shows carbonyl of amide (amide I) absorption band at 1637 cm-1 indicated to β-sheet structure of the SF due to acetone treatment.
It is indicated that SF with β-sheet and random coil structures coexist in the nanocomposite microparticles.
The FTIR results suggested that interactions between PDLL and SF were occurred due to the conformational transition of SF from β-sheet structure to random coil structure can be induced by nanocompositing with PDLL microparticle matrix.

For the photocatalytic reduction of Cr(VI), the photocatalytic activities of STBBFS catalysts were found to be strongly dependent of absorbance in UV-visible region, adsorption capacity and surface acidity, and STBBFS prepared by dry-process showed a higher photocatalytic activity compared to that prepared by hydro-chemistry method.
The crystal structure identification of STBBFSx catalysts were obtained by using Philips X’pert X-ray diffractormeter with Cu Kα radiation.
The different light absorption capacity might be attributed to the difference in the preparation method, composition, surface microstructure and phase structure in STBBFSx [11]. 2.3 Microstructure Figure 3 (a-c) show the SEM images of STBBFSx catalysts prepared at different method.
It was generally thought that the photocatalytic performance depended on the phase structure, the absorbance, and the adsorption capacity of photocatalyst[12, 13].
In our experiments, the phase structure of all photocatalysts was almost the same, so the different phtocatalytic activity should depend on the latter two factors.

Introduction The heteropoly compounds ( including heteropoly acid and heteropoly salt), especially with Keggin structure, have been used in organic synthesis[1], pharmaceutical chemistry[2] and other fields for their unique structure and the excellent catalytic performance, and were used to treat wastewater as the photocatalyst by many experts.
The character peak of the heteropoly salts with Keggin structure appears fingerprint region at the range of the 700-1100cm-1[4].
Combined with FT-IR and UV spectra, it was sure that Na5[Fe(ZrMo11)O39]•19H2O possessed Keggin structure.
The results showed it possessed Keggin structure, regular crystal and had a good thermostability.

Methyltrichlorosilane, added with silane, ethylene and hydrogen chloride were employed as precursors to perform epitaxial growths resulting in very low background doping concentration and high quality material, which could be employed for power devices structure on basal-plane-dislocation-free epitaxial layers.
Si-rich conditions were usually preferred to grow on on-axis substrates, yet thanks to Si-rich preparation of the surface C/Si ratios up to 1 were used without any occurrence of 3C inclusions, for Si/H2 = 0.45 % and a growth rate of 60 µm/h, for the SiH4 + C2H4 + HCl chemistry.
In case of the MTS chemistry ratios of 3 or 5 already ensured a 100 % polytype replica of the epilayer even at a Si/H2 ratio of 0.66 %, while in case of the SiH4 + C2H4 + HCl chemistry better results were gained by lowering the Cl/Si ratio from 5 to 1.
In case of the SiH4 + C2H4 + HCl chemistry a growth rate of 80 μm/h was achieved when C/Si = 0.8 and Cl/Si = 1 , yet 3C-SiC inclusions were still formed on the epilayer (Fig. 3a).
MTS was proved to be more efficient in terms of growth rate and polytype replication, compared to the SiH4 + C2H4 + HCl chemistry, yet the latter although suffering of lower growth rate led to better thickness uniformity along the susceptor.
