Enhanced denitrification has been reported under weak electric fields. However, it is difficult to investigate the mechanism of enhanced due complex interspecific interactions mixed-culture systems. In this study, Pseudomonas stutzeri, capable anaerobic conditions, was selected for treating low COD/N (2.0, ratio between concentration chemical oxygen demand and NO3−-N) artificial wastewater constant external voltages 0.2, 0.4, 0.6 V. The results revealed that P. stutzeri exhibited highest...

In this kinetic and thermodynamic study, the reversible outer-sphere electron-transfer reactions between a series of Ru(NH(3))(5)L(3+/2+) complexes (L = etpy, py, lut) (etpy 4-ethylpyridine; py pyridine; lut 3,5-lutidine) cytochrome c were investigated as function ionic strength, buffer, pH, temperature, pressure. Due to low driving forces these systems, it was possible study all in both redox directions. The observed rate constants for various L are correlated on basis ability ligands...
Single-electron transfer across an alkanethiolate-protected Au nanoparticle monolayer is observed (see figure) through deliberate control of the structure, interparticle interactions, and temperature. The system analogous to Coulomb-staircase phenomenon seen in STM-based measurements individual particles.

In high-altitude regions, a diminished atmospheric oxygen content significantly impairs the aeration efficiency of municipal wastewater, posing challenge to sustainable wastewater management. Consequently, conventional biological treatment methods necessitate elevated energy consumption in areas, rendering them economically and environmentally unsustainable. The simultaneous nitrification denitrification (SND) process, owing its minimal requirements, emerges as promising solution...
Manganese-substituted horse heart cytochrome c was modified at histidine-33 with the ruthenium complexes trans-(NH3)4(L)Ru−His33, where L = NH3, pyridine, or isonicotinamide. Manganese(II)-to-ruthenium(III) intramolecular electron-transfer rates were measured by pulse radiolysis as functions of concentration and temperature to obtain intermolecular rate constants activation parameters.
