Article
Full-text available
The use of renewable biomass for production of heat and electricity plays an important role in the circular economy. Degradation of wood biomass to produce heat is a clean and novel process proposed as an alternative to wood burning, and could be used for various heating applications. So far, wood degradation has mostly been studied at ambient temp...

Large variations in the polarization resistance of La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF) cathodes are reported in the literature, which are usually related to different preparation methods, sintering temperatures, and resulting microstructures. However, the influence of the electrolyte on the electrochemical activity and the rate-limiting steps of LSCF r...

Full-text available
The use of active layers is a promising strategy to improve the properties of air electrodes for solid oxide fuel cells (SOFCs). In this work, La0.8Sr0.2MnO3‐δ is combined with different oxide ion conductors Ce0.9Gd0.1O1.95, Bi1.5Y0.5O3 and Pr6O11 to form highly efficient nanocomposite active layers in a single step by spray‐pyrolysis deposition. O...
Article
Symmetrical solid oxide cells (SSOCs) with identical air and fuel electrodes have gained significant scientific interest in the last decade because they offer several advantages over conventional cell configurations. Among other features, simpler fabrication, better chemical and thermo-mechanical compatibility between cell layers, and electrode rev...
Article
Full-text available
Silicon–graphite (Si@G) anodes are receiving increasing attention because the incorporation of Si enables lithium-ion batteries to reach higher energy density. However, Si suffers from structure rupture due to huge volume changes (ca. 300%). The main challenge for silicon-based anodes is improving their long-term cyclabilities and enabling their ch...
Article
The fast growth experienced by the field of lithium‐ion capacitors (LICs) in the last five years led to tremendous progress in this technology. However, the authors have observed some parallelism with its ultracapacitor (UC) sister technology, where an over‐rapid growth in the last decade resulted in a loss of focus and the need of several tutorial...
Article
Full-text available
In the last decades, the research in Microbial Fuel Cells (MFCs) has expanded from electricity production and astewater treatment to remediation technologies, chemicals production and low power applications. More recently, capacitors have been implemented to boost the power output of these systems when applied as wastewater treatment technology. Sp...
Article
Full-text available
Granulation in bioreactors for the treatment of industrial wastewater is a common phenomenon. Anaerobic granular sludge grown on brewery wastewater is known to manifest electrical conductivity, a characteristic that previously has been related to direct interspecies electron transfer. To assess if this characteristic is more widespread, we determin...
Article
Full-text available
Bioelectrochemical systems combine electrodes and reactions driven by microorganisms for many different applications. The conversion of organic material in wastewater into electricity occurs in microbial fuel cells (MFCs). The power densities produced by MFCs are still too low for application. One way of increasing their performance is to combine t...
Article
Full-text available
The use of microbial fuel cells (MFCs) for wastewater treatment fits in a circular economy context, as they can produce electricity by the removal of organic matter in the wastewater. Activated carbon (AC) granules are an attractive electrode material for bioanodes in MFCs, as they are cheap and provide electroactive bacteria with a large surface a...
Article
Full-text available
Capacitive microbial fuel cells (MFCs) use bacteria on a capacitive anode to oxidize organics in wastewater and simultaneously charge the electrode. This study aims to gain knowledge on the performance of single activated carbon (AC) granules, which are used as capacitive bioanodes. To this end, a multi-anode MFC that allows the testing of up to 29...
Article
Full-text available
Methane-producing bioelectrochemical systems generate methane by using microorganisms to reduce carbon dioxide at the cathode with external electricity supply. This technology provides an innovative approach for renewable electricity conversion and storage. Two key factors that need further attention are production of methane at high rate, and stab...
