Summary: Polydopamine (PDA) is used as a biocompatible mediator for fabricating glucose oxidase (GOx) based bioanode of enzymatic biofuel cells (EBFCs). Through the autoxidation and polymerization of dopamine monomer, spherical PDA particles are well synthesized, and their chemical and optical characteristics are verified. The durability of the bioanode is improved by introducing polyethyleneimine (PEI) as a catalyst, which effectively suppresses the leaching out of PDA and GO(x) molecules. The suggested new catalyst shows better performance and higher power density in EBFC.

Summary: The development of high-performance hybrid nanocomposites as effective immobilization supports for oxido-reductive enzymes is crucial in enzymatic biofuel cell research. These nanocomposite based electrocatalysts, such as Pt@Fe3O4/MWCNT/PANI, show outstanding performance in enzymatic glucose biofuel cells by addressing the challenges of instability, short-lifetime, and poor electron transfer. This study synthesized a hybrid nanocomposite composed of polyaniline (PANI), multiwalled carbon nanotubes (MWCNTs), and platinum nanoparticles (Pt NPs) decorated on magnetite (Fe3O4) nanosphere, which exhibited excellent electrocatalytic activity for glucose oxidation.

Summary: An efficient activated carbon based on ZnMnO nanocomposite was synthesized and characterized. This material showed good adsorption performance for toxic chromium. The effects of parameter variations on adsorption efficiency were studied, and the pseudo-second-order reaction was found to be the most suitable kinetic model. The Langmuir model was found to be more appropriate for describing the adsorption process compared to other models. The negative values of thermodynamic parameters indicated that the adsorption process was spontaneous and stable. Among the statistical models used, the double-layer model was the best fit for the adsorption process.
