Comment on Photocatalytic degradation of RhB from an aqueous solution using Ag3PO4/N-TiO2 heterostructure and Evaluation of the effect of dose change of Fe3O4 nanoparticles on electrochemical biosensor compatibility using hydrogels as an experimental living organism model

Two published papers in Journal of Molecular Liquids inappropriately named the same equation in different ways. These errors are clarified in this comment to avoid a misunderstanding involving the determination of the band gap energy from diffuse reflectance measurements using Kubelka Munk model and Tauc plot.
