Summary: Copper tape was used as a low-cost substrate to enhance the performance of disposable carbon electrodes, which were then used for stripping analysis of heavy metals in corns. The copper substrate significantly improved the electrochemical responses of Cd2+ and Pb2+ compared to stainless steel and aluminum. This study suggests an alternative method to improve the analytical performance of disposable electrodes for electrochemical detection.

Summary: The sensitivity of screen-printed electrochemical sensors strongly depends on the selection of appropriate modifiers that optimize the chemical and physical properties of the sensor surface. This study investigated the impact of chemical and physical factors on the sensitivity of modified sensors for detecting lead and cadmium. The study found that metal-attracting functional groups and surface charge were the dominant factors affecting the sensitivity, while the physical morphology of the sensor surface had a minimal effect. The findings provide valuable insights for designing sensors for heavy metal detection.

Summary: The galvanic reaction between graphene quantum dot (GQD)-stabilized silver nanoparticles (AgNP)-modified glassy carbon (GC) surface and Hg(II) leads to the complete dissolution of AgNPs within 15 minutes and the subsequent growth of Hg(0) as a flower on the GQD surface. This unique anti-amalgamation reaction is caused by direct deposition of Hg(0) by available oxygen functional groups and strong adsorption on the GQD graphene surface, followed by subsequent growth of Hg(0) as a flower due to the galvanic reaction between AgNPs and Hg(II).

Summary: This study proposes a dependable approach for the selective and sensitive identification of zinc, cadmium and lead in different sample matrices using an over-oxidized poly(xylenol blue) film glassy carbon electrode coated with bismuth (Bi/PXBov.ox/GCE). The best conditions for determining these elements were found to be a 0.1 mol L-1 acetate buffer solution as supporting electrolyte (pH 4.5), -1.5 V accumulation potential, and 180 s accumulation duration. Under these conditions, the detection limits of Zn(II), Cd(II) and Pb(II) were 3.20 μg L-1, 0.21 μg L-1 and 1.98 μg L-1, respectively. Moreover, this novel, cheap and easy-to-prepare Bi/PXBov.ox/GCE was successfully used for the analysis of Zn(II), Cd(II) and Pb(II) in lipstick samples, with consistent results compared to inductively coupled plasma mass spectrometry.

Summary: High-yield N/O co-doped porous turbostratic carbon nanomeshes with large interlayer spacing and abundant edge defects were synthesized using a copolymerization and carbonization strategy. The optimized nanomesh showed remarkable electrochemical performance as an anode material in potassium-ion and lithium-ion batteries, with reversible ion insertion and extraction processes. The excellent performance was attributed to the synergistic contributions of defects and reactive sites induced by N/O co-doping.
