Fungi produce various types of extracellular enzymes, including the copper-containing oxidative enzyme laccase. This enzyme uses gaseous oxygen (O₂) as an electron acceptor to catalyze oxidation of phenolic compounds, and therefore it can act as a cathode biocatalyst in a microbial fuel cell (MFC). In this study, a new model of the air-cathode microbial fuel cell (AC-MFC) was constructed. For its...
Worldwide applications of ochre analysis continue to develop at a rapid pace, highlighting a number of analytical and interpretative issues. As regional source databases continue to grow, researchers have turned to the thornier issues of source allocation. In this study, we utilize LA–ICP–MS and NAA to examine archaeological pigments, ceramic paints and experimental tiles from geological sources and...
