High current density PQQ-dependent alcohol and aldehyde dehydrogenase bioanodes [PDF]

Biosensors and Bioelectronics, 2015
In this paper, we explore the bioelectrooxidation of ethanol using pyrroloquinoline quinone (PQQ)-dependent alcohol and aldehyde dehydrogenase (ADH and AldDH) enzymes for biofuel cell applications. The bioanode architectures were designed with both direct electron transfer (DET) and mediated electron transfer (MET) mechanisms employing high surface ...

A Dual-Target Recognition System Based on Acid-Degradable Ni-MOF and Aptamer Guidance for Precise Tumor Diagnosis and Combined Therapy. [PDF]

Adv Sci (Weinh)
This work reports a Ni‐doped ZIF‐8 nanoplatform co‐encapsulating glucose oxidase and horseradish peroxidase, enabling a cascade catalytic reaction that produces hydroxyl radicals from endogenous glucose and hydrogen peroxide. Upon near‐infrared irradiation, the system simultaneously achieves photothermal and chemodynamic therapy, offering an effective ...

New applications and performance of bioelectrochemical systems [PDF]

, 2010
Bioelectrochemical systems (BESs) are emerging technologies which use microorganisms to catalyze the reactions at the anode and/or cathode. BES research is advancing rapidly, and a whole range of applications using different electron donors and acceptors

Multi-system Nernst–Michaelis–Menten model applied to bioanodes formed from sewage sludge [PDF]

, 2015
Bioanodes were formed under constant polarization at 0.2 V/SCE from fermented sewage sludge. Current densities reached were 9.3 ± 1.2 A m2 with the whole fermented sludge and 6.2 ± 0.9 A m2 with the fermented sludge supernatant. The bioanode kinetics was

Separator electrode assembly (SEA) with 3-dimensional bioanode and removable air-cathode boosts microbial fuel cell performance [PDF]

, 2017
Separator electrode assemblies (SEAs) were designed by associating a microbial anode with an air-cathode on each side of three different kinds of separator: plastic grid, J-cloth and baking paper.

Successive bioanode regenerations to maintain efficient current production from biowaste [PDF]

Bioelectrochemistry, 2015
The long-term operation of efficient bioanodes supplied with waste-derived organics is a key challenge for using bioelectrochemical systems as a waste valorization technology. Here, we describe a simple procedure that allowed maintaining highly efficient bioanodes supplied with biowaste.

High-Capacitance Manganese Dioxide Oxide/Carbon Nanotube/Carbon Felt as a Bioanode for Enhanced Energy Output in Microbial Fuel Cells

Coatings, 2023
Microbial fuel cell (MFC) technology can potentially recover bioelectricity from wastewater. However, its practical applications have been limited because of its low power density and since the energy generated from an MFC cannot be stored. In this study,

Polarity inversion of bioanode for biocathodic reduction of aromatic pollutants [PDF]

Journal of Hazardous Materials, 2017
The enrichment of specific pollutant-reducing consortium is usually required prior to the startup of biocathode bioelectrochemical system (BES) and the whole process is time consuming. To rapidly establish a non-specific functional biocathode, direct polar inversion from bioanode to biocathode is proposed in this study.
