We report the use of highly porous, dense, and anisotropic TiO(2) derived from electrospun TiO(2)-SiO(2) nanostructures through titanate route in dye-sensitized solar cells. The titanate-derived TiO(2) of high surface areas exhibited superior photovoltaic parameters (efficiency > 7%) in comparison to the respective electrospun TiO(2) nanomaterials and commercially available P-25.

Lactones play crucial roles in various fields, such as pharmaceuticals, food, and materials science, due to their unique structures and diverse biological activities. However, certain lactones are difficult to obtain in large quantities from natural sources, necessitating their synthesis to study their properties and potential. In this study, we investigated the photocatalytic conversion of D-fructose, a biomass-derived and naturally abundant sugar, using a TiO photocatalyst under light irradiation in ambient conditions.

The concept of using polyaniline/titanium dioxide heterostructures as efficient photocatalysts is based on the synergistic effect of conducting polymer and metal oxide semiconductors. Due to inconclusive literature reports, the effect of different polyaniline/TiO ratios on photocatalytic activity under UV and visible light was investigated. In most papers, non-recommended dyes are used as model compounds to evaluate visible light activity.

Exosomes have emerged as a powerful biomarker for early cancer diagnosis, however, accurately detecting cancer-derived exosomes in biofluids remains a crucial challenge. In this study, we present a novel label-free electrochemical biosensor utilizing titanium dioxide nanotube array films (TiONTAs) for the sensitive detection of exosomes in complex biological samples. This innovative biosensor takes advantage of the excellent electrochemical properties of TiONTAs and their specific interactions with the phosphate groups of exosomes.

CO hydrogenation to methanol using green hydrogen derived from renewable resources provides a promising method for sustainable carbon cycle but suffers from high selectivity towards byproduct CO. Here, we develop an efficient PdZn-ZnO/TiO catalyst by engineering lattice dislocation structures of TiO support. We discover that this modification orders irregularly arranged atoms in TiO to stabilize crystal lattice, and consequently weakens electronic interactions with supported active phases.

Suture-associated surgical site infection (SSI) causes bacterial pathogens to colonize on the suture surface that are highly resistant to antibiotic treatment. Conventional suture materials used in surgical practice are causing complications such as infection and chronic inflammation. Surgical suture materials with antibacterial coatings are widely used in surgical practice.
