Low-grade heat from geothermal sources and industrial plants is a significant source of sustainable power that has great potential to be converted electricity.
Rechargeable aqueous zinc-ion batteries have been intensively studied as novel promising large-scale energy storage systems recently, owing to their advantages of high abundance, cost effectiveness, and safety. However, the development suitable cathode materials with superior performance is severely hampered by sluggish kinetics Zn2+ divalent charge in host structure. In present work, a highly reversible battery demonstrated electrolyte using V6O13·nH2O hollow microflowers composed ultrathin...
Electrochemical oxidation of p-nitrophenol was examined using different anodic materials, including Ti/boron-doped diamond (BDD), Ti/SnO2−Sb/PbO2, and Ti/SnO2−Sb anodes. The results demonstrated that Ti/BDD anodes had a much stronger mineralization performance than the other two Furthermore, it found hydroxyl radicals could mainly exist as free at BDD anodes, which react with organic compounds effectively. This implied dominant mechanism for higher capacity would be attributed to existence...
There is great controversy on how different set anode potentials affect the performance of a bioelectrochemical system (BES). It often reported that more positive improve acclimation and exoelectrogenic biofilms, alter microbial community structure, while in other studies relatively negative were needed to achieve higher current densities. To address this issue, biomass, electroactivity, structure anodic biofilms examined over wide range (-0.25, -0.09, 0.21, 0.51, 0.81 V vs standard hydrogen...
Electrochemical oxidation of some p-substituted phenols (p-nitrophenol, p-hydroxybenzaldehyde, phenol, p-cresol, and p-methoxyphenol) with electron-donating -withdrawing substituents was studied to reveal the relationship between structure electrochemical reactivity using a boron-doped diamond electrode by voltammetry bulk electrolysis. Voltammetric study shows that peak potentials become more positive an increase Hammett's constants, is, direct phenol electron-withdrawing group is difficult...
In methanogenic microbial electrolysis cells (MMCs), CO2 is reduced to methane using a biofilm on the cathode by either direct electron transfer or evolved hydrogen. To optimize generation, we examined several materials: plain graphite blocks, blocks coated with carbon black containing metals (platinum, stainless steel nickel) insoluble minerals (ferrihydrite, magnetite, iron sulfide, molybdenum disulfide), and fiber brushes. Assuming stoichiometric ratio of hydrogen (abiotic):methane...
Residues and distribution of neonicotinoid insecticides (NEOs) in soil-water-sediment systems the urban rural areas Guangzhou, South China were investigated. A total 104 soil samples from 7 different functional zones 29 water/sediment creeks collected. The results showed that at least one insecticide was detected all samples. summed levels five target neonicotinoids (∑5neonics) range 0.003–229 ng/g dw for samples, 7.94–636 ng/L water 0.017–31.3 sediment with a geometric mean 0.59 dw, 153...
Abstract Large amounts of low‐grade waste heat (temperatures <130 °C) are released during many industrial, geothermal, and solar‐based processes. Using thermally‐regenerative ammonia solutions, thermal energy can be converted to electricity in battery systems. To improve reactor efficiency, a compact, ammonia‐based flow (AFB) was developed tested at different solution concentrations, rates, cell pairs, circuit connections. The AFB achieved maximum power density 45 W m −2 (15 kW −3 ) an...
Capacitive deionization (CDI) has emerged as a promising technique for brackish water desalination. Here, composites of polypyrrole grafted activated carbon (Ppy/AC) were prepared via in situ chemical oxidative polymerization pyrrole on AC particles. The Ppy/AC cathode was then coupled with MnO2 anode desalination membrane-free CDI cell. Both the and electrodes exhibited pseudocapacitive behaviors, which can selectively reversibly intercalate Cl- Na+ (MnO2) ions. Compared to electrodes,...

The world is facing severe environmental pollution and energy shortages. Microbial electrolysis cells (MECs) provide a promising solution by producing H2 from wastewater. However, MECs face limitations, such as low current densities, slow production, electrogenic bacteria deactivation at high voltages. In this study, we developed microbial water (MWECs), new device that couples with (WE). At an applied voltage of 2.2 V, MWECs achieved industrial-level density 400 mA/cm2, fast production rate...
