Here, an unprecedented synthesis method for nickel oxide nanoparticles (NiO-NPs) was facilitated using Salvia hispanica leaf extracts with the assistance of a high gravity rotating packed bed (RPB) system that enabled fast mass transfer and molecular mixing. The synthesized nanoparticles were anchored on the surface of biodegradable chitosan nanobeads and their photocatalytic activity was evaluated by the degradation of methylene blue. Additionally, the potential biological activities of NiO-NPs in terms of antibacterial (Staphylococcus aureus and Escherichia coli for 24 hours), cytotoxicity (using the PC12 cell line for 24 and 72 hours), and antioxidant activities (based on the discoloration of the methanolic solution of DPPH) were assessed. This novel approach for NiO-NPs@Chitosan synthesis as mediated by a renewable plant extract and facilitated by a high-gravity method, led to the greener synthesis of nanoparticles with significant antibacterial and photocatalytic properties.

Methods for reducing the alkaline dosage in a two-phase UASB process were investigated. An alkaline simulation model was developed incorporating the recycle ratio of effluent, the mass transfer rate of carbon dioxide from the liquid to gas phase, and the dissociation of organic acids and carbonate. Model simulation showed that a considerable amount of alkaline was consumed needlessly in an attempt to neutralize bicarbonate generated in both the acidification phase and methanogenic phase. Decarbonation by bubbling air between the acidification section and UASB reactor was shown to be effective in reducing the amount of alkaline required for bicarbonate neutralization. Methanogenic bacteria in the system were not adversely affected by air bubbling during four months of continuous laboratory-scale operation.
