Hepatocellular carcinoma (HCC) is the fifth leading cause of cancer-related mortality worldwide. Programmed cell death ligand-1 (PD-L1) is an immune checkpoint protein that binds to programmed cell death-1 (PD-1), which is expressed in activated T cells and other immune cells and has been employed in cancer therapy, including HCC. Recently, PD-L1 overexpression has been documented in treatment-resistant cancer cells.

- The study examined how well pristine pine sawdust biochar (PSB) and post-modified PSB with Mg/Al layered double hydroxides (PSB-LDH) adsorb the azo dyes Methyl Orange (MO) and Sunset Yellow FCF (SYF).
- Despite having a lower specific surface area, PSB-LDH showed significantly better adsorption capacity for both dyes compared to PSB, indicating the successful functionalization of LDH.
- The adsorption kinetics were identified as pseudo-second-order chemisorption, with PSB-LDH demonstrating strong reusability (over 81.2%) even after multiple cycles of dye removal.
We prepared ZnO nanocomposites with WO or CuO nanostructures to improve the photocatalytic performance of ZnO nanostructures. Characterization of the nanocomposites using scanning electron microscopy, x-ray diffraction, UV-vis spectrometry and photoluminescence revealed the morphologies and wide light absorption range of the materials. The highest current densities of WO/ZnO and CuO/ZnO nanocomposites were 1.
