Manganese plays a central role in lithium-ion batteries (LIBs) but its recycling is rarely addressed when compared to other valuable metals present LIBs, such as Co and Ni. Thus, the main goal of this work was study achieve separation Mn from Ni by solvent extraction leachate obtained LIBs using hydrochloric acid an upscaled reactor, which innovative aspect work. The results confirmed high sele...

Nitrogen dioxide (NO2) absorption in aqueous sulfite solutions has recently gained more attention to reduce NOx emissions. The NO2 removal efficiency is strongly influenced by the competing reactions of and oxidation. present study investigates role oxidation at neutral pH. effects concentration, thiosulfate, pH, inlet oxygen concentration on efficiency, rates were investigated under well-contr...

Defenses against botnet-based distributed denialof-service (DDoS) attacks must demonstrate that in addition to being technically feasible, they are also economically viable, particularly when compared with the two most widely deployed defenses—simple massive overprovisioning of resources to absorb and handle DDoS traffic, and “scrubbing” of incoming traffic by the victim’s ISP. We argue that th...

Concerns over the environment and the rising costs for energy and wastewater treatment have caused a resurgence of interest in anaerobic treatment and subsequent use of the biogas produced during this treatment of organic wastes as fuel. Biogas from faecal and landfill wastes has become a potential renewable energy source for both domestic and commercial usage especially in Ghana where a 50MW c...
