In this study, two modes of hybrid anaerobic digestion (AD) bioreactor with built-in BESs (electrodes installed in liquid phase (R1) and sludge phase (R2)) were tested for identifying the effect of electrodes position on azo dye wastewater treatment. Alizarin yellow R (AYR) was used as a model dye. Decolorization efficiency of R1 was 90.41 ± 6.20% at influent loading rate of 800 g-AYR/ m(3)·d, ...

Thick-film screen printed silver-silver chloride (Ag/AgCl) reference electrodes have been fabricated and investigated as an alternative to liquid electrolyte Ag/AgCl reference electrodes. The performance of the electrodes was examined with variations of the potassium chloride (KCl) concentration in the final (top) layer of the electrode. Also, different types of binder (glass and polymer) were ...

Proton exchange membrane fuel cells (PEMFCs) have been utilized as a promising power source for new energy vehicles. Their performances are greatly affected by the structural design of flow field in bipolar plate. In this paper, we present novel three-dimensional (3D) bionic cathode field, inspired small intestinal villi. The and working principle 3D units first described. A numerical model is ...

Summary Anion-exchange membrane water electrolysis (AEMWE) suffers from low performance compared with mainstream techniques. Attempts at improvement have been confined to the development of membranes and electrodes. Here, in quest increasing AEMWE, a well-designed liquid/gas-diffusion layer (LGDL), termed as NiMPL-PTL, was developed by introducing nickel-based microporous layers (MPLs)...

Carbon fiber electrodes are crucial for the detection of catecholamine release from vesicles in single cells for amperometry measurements. Here, we describe the techniques needed to generate low noise (<0.5 pA) electrodes. The techniques have been modified from published descriptions by previous researchers (1,2). Electrodes are made by preparing carbon fibers and threading them individually in...

On the microscale, the dielectrophoretic (DEP) force may be used to control and manipulate sub-microliter volumes of liquid water using co-planar electrodes of very simple design. The basic phenomenology of liquid DEP on the microscale is familiar; water tends to collect in regions where the electric field is strongest. However, because capillarity and surface wetting become stronger as dimensi...

This research addresses the extraction and recovery of nickel ions from real electroplating wastewater using SLM process. The process involves three main phase system which are feed, organic and stripping phase. The feed phase containing the nickel electroplating wastewater whereas the organic phase containing the liquid membrane which was immobilized in the membrane support. The liquid membran...

Oxide-derived copper (OD-Cu) electrodes exhibit unprecedented CO reduction performance towards liquid fuels, producing ethanol and acetate with >50% Faradaic efficiency at -0.3 V (vs. RHE). By using static headspace-gas chromatography for liquid phase analysis, we identify acetaldehyde as a minor product and key intermediate in the electroreduction of CO to ethanol on OD-Cu electrodes. Acetalde...

Interfacial charge transfer is widely assumed to obey the Butler-Volmer kinetics. For certain liquid-solid interfaces, the Marcus-Hush-Chidsey theory is more accurate and predictive, but it has not been applied to porous electrodes. Here we report a simple method to extract the charge transfer rates in carbon-coated LiFePO4 porous electrodes from chronoamperometry experiments, obtaining curved ...

The study focuses on the challenges of implementing fuel cell technologies and materials to achieve efficient use green hydrogen zero CO2 emissions. It is shown that only identifying optimal parameters for each component technology testing system will help planned output-specific power. thorough structure optimization membrane-electrode complex in actual operating conditions accelerate implemen...
