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.

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.

The study will focus on monitoring defects and finding out the nature of these defects. Bulk GaN was irradiated by a 2 MeV electron beam at a fluence of 5×1016 cm2 and studied by deep-level transient spectroscopy (DLTS). After irradiation, a broad peak, including at least two traps, was detected. The trap D1 (EC −0.16 eV) observed from a broad peak is induced during the annealing process below 550K and completely annealed out at 550K after 10 hours.

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.

The novel MnWO4/BiOI nanocomposite materials were successfully synthesized by a precipitation deposition method. The as-prepared photocatalyst was characterized by XRD, SEM, EDAX, UV-DRS, FT-IR, TEM and BET techniques. The as-prepared MnWO4/BiOI nanocomposites were further utilized to study the degradation of the Celestin blue aqueous solution under visible-light irradiation.

The synthesis of fluorescent carbon quantum dots (CQDs) and their applications have attracted great attention due to their excellent properties. Especially, the unique visible-light absorption and photo-induced electron transfer properties make CQDs available in photocatalytic degradation of organic dye pollutants in water resources. Herein, we synthesized nondoped CQDs and boron-doped CQDs (B-CQDs) by hydrothermal method and compared their photocatalytic degradation activity of methylene blue (MB) and methyl red (MR) dyes under visible light irradiation.
