The influence of a nanodispersion of TiO in water (nanoparticle size: 40 nm, polydispersity index: 0.25), brushed on a Paraloid film and subjected to UV-Vis irradiation was evaluated. The TiO nanodispersions showed a tendency to reduce the molecular weight of Paraloid due to its photocatalytic properties. FTIR and GPC analyses and SEM images suggested the degradation of the polymer, while chromatic variations of the films were scarcely detected. This study is very remarkable in the perspective of using this material for the removal of polymeric films used in conservation.

In this present investigation, plant-mediated synthesis of titanium oxide (TiO) nanoparticles was synthesized from seagrass (Thalassia hemprichi) using the hot plate combustion method (HPCM). Synthesized TiO nanoparticles optical, functional, structural, and morphology properties were analyzed by UV-visible spectroscopy, Fourier transform infrared spectroscopy (FT-IR), powder X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDX). SEM analysis confirmed the spherical shape of the TiO nanoparticles were observed in various sizes, viz.

Photocatalytic overall water splitting is a promising approach for a sustainable hydrogen provision using solar energy. For sufficient solar energy utilization, this reaction ought to be operated based on visible-light-active semiconductors, which is very challenging. In this work, an F-expedited nitridation strategy is applied to modify the wide-bandgap semiconductor SrTiO for visible-light-driven photocatalytic overall water splitting.

The temporal variation and transport of Cs in the Beibu Gulf (BG) are still poorly understood. Here we measured Cs concentrations in the BG water column and surface sediments during 2022. We found that Cs in the BG water column was controlled by the movement and mixing of local water masses.

Nature-inspired superhydrophobic materials have attracted considerable interest in blood-contacting biomedical applications due to their remarkable water-repellent and self-cleaning properties. However, the interaction mechanism between blood components and superhydrophobic surfaces remains unclear. To explore the effect of trapped air on platelet adhesion, we designed four distinct hydrophobic titanium dioxide (TiO) nanostructures with different fractions of trapped air.
