A facile method is reported to synthesize macroporous silica films embedding rhodamine 6G. The were obtained by sol-gel and spin-coating processes. Results pointed out a dependence of pore formation on the addition 6G in film composition. probable process pores was attributed aggregation charged species from Although randomly distributed surface, size tuned at certain extent controlling evapora...

Zirconium Oxide (ZrO2) is an interesting material in optical filters, gas sensors and protective coatings owing to their outstanding optical, chemical, thermal and mechanical properties. Zirconium Oxide thin films were deposited on glass substrates by sol gel dip coating method, using alcoholic solutions. The dipping solution was prepared from Zirconium OxychlorideOctahydrate and Isopropanol wi...

Hydroxyapatite (HAp) is commonly used to coat titanium alloys (Ti-6Al-4V) for orthopedic implants. However, their poor adhesion strength and insufficient long-term stability limit their application. Novel sphene (CaTiSiO5) ceramics possess excellent chemical stability and cytocompatibility. The aim of this study is to use the novel sphene ceramics as coatings for Ti-6Al-4V. The sol-gel method w...

Surfactant-templated mesostructured sol–gel films formed by evaporation induced self assembly (EISA) exhibit highly-ordered hexagonal, lamellar, and cubic structures. The steady-state dip-coating configuration allows both the chemistry and the dynamics of the EISA process to be traced in real time because the steps involved in the formation of the mesostructured material are separated both spat...

Optically transparent superhydrophobic silica-based films were obtained by means of sol–gel processing and self-assembly (SA). Desired surface roughness was obtained by tuning the microstructures of the sol–gels through careful control of hydrolysis and condensation reactions of various silica precursors during sol–gel processing, whereas modification of surface chemistry was done by introducin...

A facile sol–gel coating procedure has been successfully applied for the ZrO2 coating of eggshell membranes (ESM), resulting in hierarchically ordered thin films with a macroporous network structure comprising crystalline ZrO2 tubes. This hierarchical material, which was obtained through sol–gel mineralization of the ESM template and subsequent calcination at 600 uC, was characterized by XRD, S...

The phosphorus barrier layers at the doping procedure of silicon wafers were fabricated using a spin-coating method with a mixture of silica-sol and tetramethylammonium hydroxide, which can be formed at the rear surface prior to the front phosphorus spin-on-demand (SOD) diffusion and directly annealed simultaneously with the front phosphorus layer. The optimization of coating thickness was obta...
