Summary: This study aims to evaluate the potential of using a thermophilic acidophilic red alga, Galdieria sulphuraria, for on-site treatment of landfill leachate. The optimal conditions for biomass production were found to be 20% strength leachate, an initial biomass concentration of 0.25 g L-1, and the addition of nitrogen at twice the level of initial media. The study also showed that G. sulphuraria can grow in elevated NH4-N concentration and provide high nitrogen removal rates. The long-term experiment demonstrated the feasibility of using the algal-based system for bioremediation in a semi-continuous mode.

Summary: In this study, an in-plane micro-supercapacitor with a unique electrode structure was developed using laser annealing and ablation techniques. Laser annealing carbonized the polyamide acid, reducing the resistivity of the composite film. Laser ablation was used to create through-holes in the interdigitated electrode structure. By increasing the surface area of the carbon layer through these through-holes, the capacitance of the micro-supercapacitor was improved.

Summary: Given the low recycling rate of plastic waste in the United States, developing an economically favorable technology to upgrade plastic waste is of great interest. This study modeled a facility that converts 250 metric tons of plastic waste per day and produces a high-quality liquid (HQL) similar to polyalphaolefin (PAO) lubricants. The techno-economic analysis and life cycle assessment showed promising results, with a production cost range of $0.6-$1.98 per kg of lubricant and a significant reduction in greenhouse gas emissions compared to petroleum and PAO lubricants.

Summary: This study synthesized biochar based on sapropel and investigated the effects of chemical modification on its textural characteristics, acid-base properties, and adsorption properties. The results showed that the chemical modification increased the fraction of micropores, specific surface area, and changed the surface properties of biochar. The experiment also revealed that biochar pretreated with alkali exhibited the maximum adsorption capacity for copper ions. A conceptual model identifying the mechanisms of copper adsorption on sapropel-based biosorbent was proposed.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
