Mechanistic Design of Graphdiyne‐Based Multimodal Sensing Integrating Machine Learning and Photothermal Dynamics for Precision Recognition and On‐Demand Inactivation

Advanced Science, Volume 13, Issue 37, 3 July 2026.
A triple‐mode theranostic platform enables integrated electrochemical, colorimetric, and photothermal detection of bacterial infection. Glucose oxidation triggers H2O2 generation and TMB oxidation to oxTMB, producing color and thermal signals under 808 nm NIR irradiation.

Optimizing Microbial Fuel Cell Efficiency Through a Designed Electrogenic Consortium to Remove Alkylbenzenes

ChemElectroChem, Volume 13, Issue 10, 19 May 2026.
A mangrove‐derived electrogenic microbial consortium was successfully acclimated to codegrade ethylbenzene and xylenes in a microbial fuel cell (MFC). Acclimation provided high degradation efficiencies (up to 97%) and improved energy recovery. The MFC reached voltage of 520 mV and power density of 63.4 mW m−2.

Biohybrid Moist‐Electric Generators Enable Autonomous Proton Homeostasis for Stable Wearable Microbial Power

Advanced Energy and Sustainability Research, Volume 7, Issue 5, May 2026.
A biohybrid moist‐electric generator converts ambient humidity into a self‐regulating proton supply for wearable microbial fuel cells. Dormant Bacillus subtilis endospores harvest moisture at the skin–air interface and deliver protons through a Nafion ionomer bridge to the air cathode, suppressing pH splitting and stabilizing power output—reframing ...

Mitigating VFA accumulation in hydrogen‐assisted anaerobic digestion through MEC integration

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 4, Page 915-924, April 2026.
Abstract BACKGROUND Biological hydrogenotrophic methanization is a promising method to improve biogas quality in anaerobic digestion systems. However, hydrogen‐assisted anaerobic digesters (AD‐H2) are prone to volatile fatty acid (VFA) accumulation and process instability.

Cascade hydrogen production from butyrate-type straw fermentation effluent using a microbial electrolysis cell [PDF]

RSC Advances
In order to solve the problem that butyric acid is difficult to be degraded in butyrate-type fermentation effluent, corn straw was used as a substrate for dark fermentation to produce hydrogen, and different substrates (butyric acid, acetic acid, and ...

Genetically Boosting Electron Transfer in Electroactive Biofilms for Improved Sensitivity of Microbial Fuel Cell‐Based Biosensing

Microbial Biotechnology, Volume 19, Issue 4, April 2026.
Engineering Geobacter biofilms through the manipulation of the cyclic GMP‐AMP signalling system led to the formation of thin, highly conductive bioanodes. This boosted extracellular electron transfer, enabling a microbial fuel cell biosensor with a 20‐fold lower Cd(II) detection limit (0.03 mg L−1) by increasing cytochromes/nanowires and reducing ...
