Electricity production enhancement in a constructed wetland-microbial fuel cell system for treating saline wastewater.

The use of constructed wetlands in combination with microbial fuel cells (CW-MFC) to treat saline wastewater may enhance electricity production by increasing the ionic strength, reducing internal resistance and stimulating microbes to accelerate electron transfer. In this study, salinity did not significantly inhibit the removal of TP and COD, but TN and NH-N removal efficiencies during saline wastewater treatment (ST) were significantly lower than during non-saline wastewater treatment (NT). However, salinity significantly increased the power density (16.

Two-Dimensional VO Mesoporous Microarrays for High-Performance Supercapacitor.

Two-dimensional (2D) mesoporous VO microarrays have been prepared using an organic-inorganic liquid interface. The units of microarrays consist of needle-like VO particles with a mesoporous structure, in which crack-like pores with a pore size of about 2 nm and depth of 20-100 nm are distributed on the particle surface. The liquid interface acts as a template for the formation of the 2D microarrays, as identified from the kinetic observation.
