TL;DR: In this paper, a characterization of polyaniline (PANI) by electrochemical and spectroscopic techniques is presented, which reveals the influence of the dopant acid on the kinetic parameters, such as exchange current density (I0) and the cathodic transfer coefficient (αc).

TL;DR: Graphene is a remarkable material with great potential in many applications due to its chemical and physical properties as discussed by the authors, and the recent research progress (2016-2018) in graphene and graphene-based nanomaterials synthesis is briefly presented in this review.

TL;DR: In this article, a simple and efficient approach for graphene production, by electrochemical exfoliation of graphite rods, in acidic solutions, was reported, where the applied bias and electrolyte concentration were optimized.

TL;DR: In this paper, the authors reported on the preparation of gold electrodes modified with graphene-AuAg (Au/Gr-AgAg) or graphene composite materials as electrochemical sensors for dopamine (DA) detection.

TL;DR: In this article, the catalytic activity of N-doped graphene toward a peroxidase substrate oxidation in the presence of hydrogen peroxide was investigated and compared with that of metallic nanoparticles decorated-graphene, achieved either by catalytic chemical vapor deposition with induction heating (CCVD-IH) or by chemical reduction of graphene oxide (GO).
