Summary: In this study, organic-inorganic composites F70-TiO2 were designed and constructed to become an optical-functional photocatalyst. The optimized composition of F70-TiO2(1:15) demonstrated high photocatalytic activity for the conversion of benzylamine to N-benzylidene benzylamine under visible light irradiation. The introduction of fullerene derivatives into anatase TiO2 greatly enhanced the sunlight utilization and promoted the charge separation and transfer.

Summary: The Sol-gel method was used to prepare a Si-Ti-epoxy organic-inorganic hybrid composite sol, which was cured on the carbon steel surface to form a transparent film with excellent electrochemical protection performance and hydrophobicity. The Si-Ti-epoxy hybrid film has a denser structure, higher impedance modulus, and lower corrosion current density compared to a double-thick epoxy film.

Summary: We investigated the AC electrical response of MgFe2O4-Nb2O5 nanocomposite and synthesized the nanocomposite using a simple combustion method. The structural characterization of the nanocomposites was performed using FTIR, XRD, SEM, and EDX methods. The results showed that doping Nb2O5 can enhance the AC conductivity of MgFe2O4-Nb2O5 nanocomposite. The polarization mechanism of conductivity was explained by permittivity and impedance spectroscopy.

Summary: The research synthesized TiO2 through a sol-gel process and bentonite through ball milling, coprecipitation, and surfactant addition, forming a nanocomposite material. Characterization of the nanocomposite revealed important properties such as particle size, absorption peaks, and morphology. The results showed the occurrence of TiO2 pillarization in bentonite and the content of TiO2 and SiO2 in the nanocomposite.

Summary: Cu and Y co-doped TiO2 nanoparticles were prepared using an acid-catalytic sol-gel process, resulting in a single anatase phase with reduced crystallite size. SEM observations showed uniform nanospheres being synthesized under the proposed conditions. XPS results demonstrated the presence of Cu+ and Y3+ ions. The photoactivity of the co-doped TiO2 was improved due to effective separation of electron-hole pairs, increased formation of active radicals, and increased surface area.

Summary: The addition of SiO2 in the TiO2/SiO2 nanocomposite significantly enhances the photocatalytic and antibacterial abilities of the silicate coating, with the best performance observed at a SiO2 content of 15%. This is attributed to the larger surface area provided by TiO2/SiO2 Nc (15%) in the W silicate coating, which increases centers for absorption, photocatalytic reactions, and contact between the sample and bacteria.

Summary: This study successfully crystallizes TiO2 thin films from a sol-gel solution using near-infrared laser annealing, with gold nanoparticle arrays as nano-heaters. The presence of the anatase phase confirms the temperature increase achieved by the laser, and different analytical techniques support the findings. A numerical model highlights the role of nanoparticle coupling in the photothermal effect. Direct laser patterning and photolithography techniques are demonstrated. This fabrication method has promising applications in photonics, photocatalysis, and biosensing.

Summary: This study investigated the effect of the mixing ratio of TiO2 nanoparticles (P25) and titanium alkoxide (T-sol) on various properties of TiO2 films. The specific surface area, microstructure, thickness, transmittance, pencil hardness, and oil contact angle of the films were analyzed. The results showed that the specific surface area increased as the P25 content increased, but this effect decreased as the ratio of T-sol to P25 increased. The thickness, surface roughness, transmittance, pencil hardness, and oil contact angle of the films were also affected by the P25 content, with increased thickness and surface roughness, decreased transmittance and pencil hardness, and decreased oil contact angle.

Summary: The study investigates the effects of Cr and N doping on the properties of TiO2 anatase nanoparticles, including adsorption capacity, photocatalytic performance, and antibacterial response. Doping with Cr and Cr/N enhances adsorption capacity and photocatalytic performance, with Cr-TiO2 nanoparticles exhibiting antibacterial activity under visible light. The differences in electrostatic charge and nanoparticle dispersion are suggested as the main reasons for the varied antibacterial response among the doped nanoparticles.

Summary: In this study, four novel organic-inorganic hybrid materials were synthesized using the sol-gel method. The materials were based on different molecular weights of Jeffamines and ECHETMS, and characterized using various techniques. The influence of Jeffamine molecular weight on the suitability of these materials as a supporting matrix for heteroaromatic probes was assessed and discussed, and the materials were found to exhibit interesting properties for a wide range of sensing applications.

Summary: Direct printing of spin-on functional films is an efficient method to develop low-cost photonic nanodevices. In this study, high refractive index TiO2 micro- and nano-structures were obtained by combining thermal nanoimprint lithography with UV curing. The patterns were achieved by depositing a hybrid organic-inorganic spin-on film using sol-gel processing. The further UV irradiation converted the imprinted films to totally inorganic patterns, allowing high refractive indexes to be achieved. This novel strategy allows inorganic deep patterns to be fabricated without a calcination step.
