Different exfoliation methods were applied to obtain reduced graphene oxide (rGO) with varied lateral sizes. Photothermal studies under near-infrared (NIR) irradiation showed efficient heat generation. Sheet size had minimal influence on the photothermal performance.

The evolution of open circuit potential (OCP) over time was monitored to evaluate corrosion resistance of aluminium alloys. Localized attack occurred even at more noble potentials. This highlights the limitations of using OCP as a standalone technique for corrosion resistance assessment.
