Analysis of bio-anode performance through electrochemical impedance spectroscopy [PDF]
, 2015 In this paper we studied the performance of bioanodes under different experimental conditions using polarization curves and impedance spectroscopy. We have identified that the large capacitances of up to 1 mF·cm− 2 for graphite anodes have their origin ...

Moving bed capacitive bioanodes
, 2021 Wastewater treatment is required to remove pollutants such as organics. The chemical energy in organics can be recovered using anaerobic treatment: anaerobic digestion (AD) to produce biogas, or bioanodes to directly produce electrical current. In practice 26% of the energy can recovered as electricity using AD.

Glucose-Sensitive Biohybrid Roots for Supercapacitive Bioanodes
ACS Applied Bio MaterialsPlants as living organisms, as well as their material-structural components and physiological processes, offer promising elements for developing more sustainable technologies. Previously, we demonstrated that plants could acquire electronic functionality, as their enzymatic activity catalyzes the in vivo polymerization of water-soluble conjugated ...
