Scaling-up of a novel, simplified MFC stack based on a self-stratifying urine column (2016)
Journal Article
Walter, X. A., Gajda, I., Forbes, S., Winfield, J., Greenman, J., & Ieropoulos, I. (2016). Scaling-up of a novel, simplified MFC stack based on a self-stratifying urine column. Biotechnology for Biofuels, 9(1), https://doi.org/10.1186/s13068-016-0504-3

© 2016 Walter et al. Background: The microbial fuel cell (MFC) is a technology in which microorganisms employ an electrode (anode) as a solid electron acceptor for anaerobic respiration. This results in direct transformation of chemical energy into e... Read More about Scaling-up of a novel, simplified MFC stack based on a self-stratifying urine column.

On hybrid circuits exploiting thermistive properties of slime mould (2016)
Journal Article
Walter, X. A., Horsfield, I., Mayne, R., Ieropoulos, I. A., & Adamatzky, A. (2016). On hybrid circuits exploiting thermistive properties of slime mould. Scientific Reports, 6(23924), https://doi.org/10.1038/srep23924

Slime mould Physarum polycephalum is a single cell visible by the unaided eye. Let the slime mould span two electrodes with a single protoplasmic tube: if the tube is heated to approximately ≈40 °C, the electrical resistance of the protoplasmic tube...

From single MFC to cascade configuration: The relationship between size, hydraulic retention time and power density (2016)
Journal Article
Walter, X. A., Forbes, S., Greenman, J., & Ieropoulos, I. A. (2016). From single MFC to cascade configuration: The relationship between size, hydraulic retention time and power density. Sustainable Energy Technologies and Assessments, 14, 74-79. https://doi.org/10.1016/j.seta.2016.01.006

© 2016 The Authors. Achieving useful electrical power production with the MFC technology requires a plurality of units. Therefore, the main objective of much of the MFC research is to increase the power density of each unit. Collectives of MFCs will...

Microbial fuel cells continuously fuelled by untreated fresh algal biomass (2015)
Journal Article
Walter, X. A., Greenman, J., Taylor, B., & Ieropoulos, I. A. (2015). Microbial fuel cells continuously fuelled by untreated fresh algal biomass. Algal Research, 11, 103-107. https://doi.org/10.1016/j.algal.2015.06.003

© 2015. Microbial fuel cells (MFCs) are energy transducers that convert organic matter directly into electricity, via the anaerobic respiration of electro-active microorganisms. An avenue of research in this field is to employ algae as the organic c... Read More about Microbial fuel cells continuously fuelled by untreated fresh algal biomass.

Intermittent load implementation in microbial fuel cells improves power performance (2014)
Journal Article
Greenman, J., Walter, X. A., & Ieropoulos, I. (2014). Intermittent load implementation in microbial fuel cells improves power performance. Bioresource Technology, 172, 365-372. https://doi.org/10.1016/j.biortech.2014.09.034

© 2014 Elsevier Ltd. This study reports on the response of small-scale MFCs to intermittent loading, in terms of power output over time. The aim was to understand the evolution with time of power output under different duty cycles, in conditions clos...

Oxygenic phototrophic biofilms for improved cathode performance in microbial fuel cells (2013)
Journal Article
Ieropoulos, I. A., Walter, X. A., Walter, X. A., Greenman, J., & Ieropoulos, I. (2013). Oxygenic phototrophic biofilms for improved cathode performance in microbial fuel cells. Algal Research, 2(3), 183-187. https://doi.org/10.1016/j.algal.2013.02.002

The rate of oxygen reduction reaction in the cathodic chambers of microbial fuel cells (MFCs) is a typical limiting aspect of its performance. Recently, research on biocathodes has gained more interest as it allows circumventing the utilisation of ex...
