From a sustainability standpoint, TiO2 semiconductor photocatalyst has a lot of potential in water purification. However, due to TiO2's high band gap and rapid recombination rate of electron/hole (e−/h+) pairs, visible light exposure is not practicable. To overcome these limitations, this study inve...

The thiosemicarbazone containing polydentate Schiff base ligand is attracting interest in the field of coordination and biological application. The metal complexes exhibited stronger activity than free ligands against both cancer and bacteria due to the greater lipophilicity of complexes. These liga...

Abstract Removal of hydrogen sulfide (H2S) from raw biogas is essential for feeding the refined gas with high methane (CH4) content in engines and combustion units. In small-scale farmhouses and power plants, a cheap, inexpensive, and facile desulfurization process is needed. Herein, the desulfuriza...
