Recent studies have shown that blue light-emitting diode (LED) light has anti-tumor effects, suggesting the possibility of using visible light in cancer therapy. However, the effects of blue light irradiation on cells in the tumor microenvironment, including tumor-associated macrophages (TAMs), are unknown.

Our research unveils the synthesis of BiVO4-Bi2O3 triangular sheet composites, demonstrating their impact on charge separation ability under visible light irradiation. We found that composites with optimal BiVO4 content exhibit enhanced photocurrent density, reduced interfacial resistance, prolonged carrier life, increased surface active sites, improved charge transfer efficiency, and carrier concentration.

The present objective of this work is to find photoactive materials capable of facilitating visible light-driven redox reactions between CO2 and H2O. Our research is primarily focused on the incorporation of nitrogen (N) into the crystal lattice of titanium dioxide (TiO2) and its deposition onto Fe-MIL-88B to improve light absorption properties, minimize recombination of photo-generated electron-hole pairs, and increase CO2 adsorption capacity.

In this study, a TiO2-CeO2 heterostructure was synthesized using a cost-effective hydrothermal technique, suitable for continuous industrial-scale production and environmental remediation applications. The photocatalytic activity of the TiO2-CeO2 heterostructure was examined with MB dye under visible light irradiation. Significantly enhanced photocatalytic activity was observed compared to pure TiO2 nanoparticles.

In this study, the B/ZnO materials were simply synthesized via a Sol-gel method. The photocatalytic ability of materials was evaluated by degrading tetracycline hydrochloride (TCH). The characteristics of the ZnO and 3B/ZnO materials were analyzed and evaluated by the Diffuse Reflectance UltravioletVisible (DR/UV-Vis), Scanning Electron Microscope (SEM), Fourier Transform Infrared Spectroscopy (FT-IR), and X-Ray Diffraction (XRD) techniques.

In this work, gold nanorods (AuNRs) with well-controlled aspect ratios were prepared using a modified seedgrowth method and covered by TiO2 layers through the hydrothermal reaction to improve stability. Integrating TiO2 with plasmonic rod-like gold nanoparticles could enhance their photo activity by the local surface plasmon resonance (LSPR) effect. AuNRs aspect ratios were controlled by varying the amount of seed solution, reducing agents, surfactant (CTAB), and titanium (IV) but oxide.

Additionally, factors like pH, the amount of dye, the amount of the substance under study, and the brightness of the light were examined for their impact on the reaction rate. The efficiency of the reaction in using light was calculated. Finally, a possible explanation of how the reaction works was formulated in the proposed mechanism.

In this study, a simple technique combining conventional electrospinning and facile gas–solid reaction for fabricating PAN/Ag2S nanofibers was presented and tested. The obtained fibers would have excellent properties such as the flexibility of PAN nanofibers and efficient photocatalysis of the Ag2S nanoshells under visible light. The photocatalytic elimination of RhB in water was used to evaluate the activity and application of the synthesized material under visible light irradiation.

In this study, we successfully synthesized europium-doped TiO2 (TiO2 :Eu3+) nanomaterials (NMs) with crystalline sizes ranging from 6.5 to 71.7 nm through a sol-gel method. Analysis of X-ray diffraction (XRD) patterns and ultraviolet-visible (UV-Vis) spectra indicates that the substitution of smaller-sized Ti4+ ions (0.745 Å) by largersized Eu3+ ions (0.947 Å) was more efficient at higher doping concentrations and annealing temperatures.

here are various positioning algorithms proposed for Visible Light Communication (VLC) which require at least three “alive” transmitters to locate the object’s position. In terms of indoor scenarios, the shadowing of Line-of-sight (LOS) signal leads to insufficient information for positioning in a VLC system.
