Different microbial electrochemical technologies are being developed for many diverse applications, including wastewater treatment, biofuel production, water desalination, remote power sources, and biosensors. Current energy densities will always be limited relative to batteries chemical fuel cells, but these have other advantages based on the self-sustaining nature of microorganisms that can donate or accept electrons from an electrode, range fuels used, versatility in chemicals produced....

Air cathodes used in microbial fuel cells (MFCs) need to have high catalytic activity for oxygen reduction, but they must also be easy manufacture, inexpensive, and watertight. A simple one-step, phase inversion process was here construct an inexpensive MFC cathode using a poly(vinylidene fluoride) (PVDF) binder activated carbon catalyst. The enabled preparation at room temperatures, without the additional heat treatment, it produced first time that did not require separate diffusion layer...

Abstract Activated carbon (AC) is a low‐cost and effective catalyst for oxygen reduction in air cathodes of microbial fuel cells (MFCs), but its performance must be maintained over time. AC was modified by three methods: 1) pyrolysis with iron ethylenediaminetetraacetic acid (AC‐Fe), 2) heat treatment (AC‐heat), 3) mixing black (AC‐CB). The maximum power densities after one month these were 35 % higher AC‐Fe (1410±50 mW m −2 ) AC‐heat (1400±20 ), 16 AC‐CB (1210±30 than plain (1040±20 versus...

Conventional fluorescent microspheres (CFMs) have the disadvantages of low photoluminescence intensity (aggregation-caused quenching) and poor antibody conjugation. Herein, we achieved improved performance lateral flow immunoassay (LFIA) based on high-fluorescent property aggregation-induced emission (AIEFMs) biofriendly coupling strategy polydopamine (PDA) layer. Although PDA layer quenches fluorescence AIEFM by Förster resonance energy transfer (FRET), quenching can be effectively...
