BACKGROUND
Remediation of wastewater using microalgae is an alternative way of reducing environmental impacts associated with wastewater treatment while simultaneously generating biomass that can be converted into biofuels. In this study, the phycoremediation of a secondary urban effluent by native microalgae was investigated using a photobioreactor designed to receive carbon dioxide (CO2). The experiments...
Carbon nanofibers (CNF) were synthesized by a glow-arc discharge at frequencies of 42 kHz and at relatively low power supply (360 W) under a helium-methane atmosphere. The behaviour of temporal evolution of voltage and current discharges is studied. The product obtained was analyzed by scanning and transmission electron microscopy and Raman scattering, showing CNF relatively free of amorphous-carbon...
