Oxygen Transport in Composite Biocathodes

ECS Proceedings Volumes, 2002
A recent advance in the engineering of biological oxygen cathodes has resulted in a laccase cathode that, when mounted on a rotating disk, operates at a current density controlled by transport of oxygen to the disk surface. Indeed, electrodes have been demonstrated that generate current densities near 5 mA/cm at 1000 rpm, greatly exceeding the current ...

A Dual‐Target Recognition System Based on Acid‐Degradable Ni‐MOF and Aptamer Guidance for Precise Tumor Diagnosis and Combined Therapy

Advanced Science, Volume 12, Issue 42, November 13, 2025.
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 ...

Charge storage capacity of electromethanogenic biocathodes

Journal of Energy Storage
[EN] Methanogenic biocathodes (MB) can convert CO2 and electricity into methane. This feature, that allows them to potentially be used for long-term electrical energy storage, has aroused great interest during the past 10 years. MB can also operate as biological supercapacitors, a characteristic that can be exploited for short-term energy storage and ...

Effect of MWCNT-modified graphite felts on hexavalent chromium removal in biocathode microbial fuel cells

, 2017
Multi-walled carbon nanotubes (MWCNTs) and oxidative acid pretreated MWCNTs (oxidized MWCNTs, O-MWCNTs) were used to modify graphite felts as biocathode electrodes in Cr(vi)-reducing microbial fuel cells (MFCs).
