Abstract
Chlorpyrifos (CP) is a globally used pesticide with acute toxicity. This work studied the photocatalytic degradation of CP using TiO2, ZnO nanoparticles, and nanocomposites of TiO2 and ZnO supported on SPIONs (SPION@SiO2@TiO2 and SPION@SiO2@ZnO). The nanocomposites were synthesized by multi-step incipient wetness impregnation. The effects of the initial pH, catalyst type, and dose were evaluated. The nanocomposites of SPION@SiO2@TiO2 and SPION@SiO2@ZnO showed higher CP photodegradation levels than free nanoparticles, reaching 95.6% and 82.3%, respectively, at pH 7. The findings indicate that iron oxide, as a support material for TiO2 and ZnO, extended absorption edges and delayed the electron-hole recombination of the nanocomposites, improving their photocatalytic efficiency. At the same time, these nanocomposites, especially SPION@SiO2@TiO2, showed efficient degradation of 3,5,6-trichloropyridinol (TCP), one of the final metabolites of CP. The stability and reuse of this nanocomposite were also evaluated, with 74.6% efficiency found after six cycles. Therefore, this nanomaterial represents an eco-friendly, reusable, and effective alternative for the degradation of chlorpyrifos in wastewater treatment.

Abstract
Titanium dioxide (TiO2) photocatalysis can harness the energy from sunlight, providing a solution to many green- and energy-related problems. In this study, we aimed to produce Cu doped TiO2 (Cu-TiO2) structures at a low temperature (~70 °C) under atmospheric pressure based on liquid phase deposition. The products prepared with Cu nitrate exhibited anatase-phase TiO2 with the presence of Cu, and the particles showed a waxberry-like structure. Changing the Cu nitrate concentration allowed control of the atomic concentration; we confirmed ~1.3 atm.% of Cu ions in the product when we applied 10 mM in the precursor solution. By doping Cu, the light absorption edge shifted to 440 nm (~2.9 eV), and we proved the photocatalytic reaction through action spectral measurement. We observed the decomposition of acetaldehyde into CO2 on Cu-TiO2 photocatalysts, which produced optimized improvements in photocatalytic activity at Cu dopant levels between 0.2 and 0.4 atm.%. This study demonstrates that the liquid phase deposition technique can be used for doping metallic ions into TiO2, which shows promise for preparing novel and unique nanomaterials as visible light photocatalysts.

Bioinorg Chem Appl 2022; 2022:9602725.

Abstract
In this study, cells from human Chronic Myelogenous Leukemia (K562) were cultivated with CuO-TiO2-Chitosan-Berbamine nanocomposites. We examined nanocomposites using XRD, DLS, FESEM, TEM, PL, EDAX, and FTIR spectroscopy, as well as MTT for cytotoxicity, and AO/EtBr for apoptotic morphology assessment. The rate of apoptosis and cell cycle arrests was determined using flow cytometry. Flow cytometry was also employed to identify pro- and antiapoptotic proteins such as Bcl2, Bad, Bax, P53, and Cyt C. The FTIR spectrum revealed that the CuO-TiO2-Chitosan-Berbamine nanocomposites were electrostatically interlocked. The nanocomposites' XRD signals revealed a hexagonal shape. In the DLS spectrum, nanocomposites were found to have a hydrodynamic diameter. As a result of their cytotoxic action, nanocomposites displayed concentration-dependent cytotoxicity. The nanocomposites, like Doxorubicin, caused cell cycle phase arrest in K562 cells. After treatment with IC50 concentrations of CuO-TiO2-Chitosan-Berbamine nanocomposites and Doxorubicin, a substantial percentage of cells were in G2/M stage arrest. Caspase-3, -7, -8, -9, Bax, Bad, Cyt C, and P53 expression were considerably enhanced in K562 cells, whereas Bcl2 expression was decreased, indicating that these cells may have therapeutic potential against human blood cancer/leukemia-derived disorders. As a result, the nanocomposites demonstrated outstanding anticancer potential against leukemic cells. CuO-TiO2-Chitosan-Berbamine, according to our findings.
