Role of the Electroactive and Non-electroactive Surface Area (EASA and nEASA) for Electroactive Biofilms in Bioelectrochemical Systems

Chemical Engineering Transactions, 2023
The role of the electroactive surface area (EASA) and of the non-electroactive surface area (nEASA) was studied to better understand electroactive biofilm’s (EAB) growth and performance in four different systems.

3D Printing as an Adaptive Tool for Sensor Fabrication Applied through pH Monitoring

ChemElectroChem, Volume 12, Issue 22, November 5, 2025.
Schematic process of the fabrication of 3D‐printed electrodes, their modification into pH sensors and implementation on an ammonia recovery bioreactor. Carbon black/polylactic acid 3D electrodes are electrodeposited with a layer of iridium oxide, that result in stable and super‐Nernstian pH sensors, and painted with a layer of silver to be turned into ...

From microbial fuel cell (MFC) to microbial electrochemical snorkel (MES): maximizing chemical oxygen demand (COD) removal from wastewater [PDF]

, 2011
The paper introduces the concept of the microbial electrochemical snorkel (MES), a simplified design of a “short-circuited” microbial fuel cell (MFC). The MES cannot provide current but it is optimized for wastewater treatment.

Dynamically Adaptive Control System for Bioanodes in Serially Stacked Bioelectrochemical Systems

Environmental Science & Technology, 2013
Microbial bioelectrochemical systems (BESs) use microorganisms as catalysts for electrode reactions. They have emerging applications in bioenergy, bioproduction, and bioremediation. BESs can be scaled up as a linked series of units or cells; however, this may lead to so-called cell reversal.
