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: In this study, titanium dioxide scaffolds were successfully synthesized using the sol-gel method. The scaffolds were formed by using titanium isopropoxide as a precursor and a polymeric network of galactopyranose as a template. The synthesized scaffolds have diameters of 50 nm and porosity ranging from 0.3 to 10 nm. XRD analysis confirmed the formation of crystalline phases in the TiO2 scaffold at 700 degrees C. The use of biological polymers as templates provides a low-cost and efficient approach for the synthesis of new materials.

Summary: Due to polluted water remediation, semiconductor nano photocatalysis has been considered as a promising approach to address the issue. However, the slow reaction rates and high electron-hole recombination have hindered their large-scale applications. In this study, heterogeneous nano photocatalysts, such as sol-gel-based mesoporous titania nanoparticles (TNPs) and silica-titania nanocomposite (STNC) supported with CdTe (CdTe/STNC), were synthesized for photocatalytic applications. The CdTe/STNC catalyst exhibited a large surface area and pore size distribution, and demonstrated high photocatalytic activity with methylene blue degradation of 95% after 180 min of ultraviolet radiation.

Summary: The application of hydroxyapatite (HAp)/multi-walled carbon nanotube composites in the medical field as prosthetic coatings has become widespread due to the enhanced mechanical properties provided by carbon nanotubes. However, there has been little research on the photoluminescent properties of these composites, as well as the effect of different amounts of multi-walled carbon nanotubes and the changes in these properties over time. This study showed that the photoluminescent response of HAp and HAp/multi-walled carbon nanotubes functionalized with oxygen groups (OMWCNT) composites remained stable over time. Regardless of the amount of OMWCNT used and the thermal treatment, the passivation of surface defects resulted in a stabilized photoluminescent response. Ultimately, the photoluminescent properties of these composites could expand their use in the medical field or pave the way for new applications.
