Summary: Adsorbents derived from biological materials are crucial for the remediation of various toxic pollutants due to their high efficacy, low cost, and environmental friendliness. The ultrasonic-assisted preparation of activated carbon from palm shell activated using oleic acid was found to be highly efficient for acenaphthene removal from aqueous solution, with a high adsorption capacity of 52.745 mg/g. The Sips isotherm model provided the best fit among the examined isotherm models, confirming the suitability of the activated carbon for acenaphthene adsorption.

Summary: This study explored the use of Agave americana fibers for the preparation of activated carbon via chemical activation with phosphoric acid, and investigated the effects of preparation conditions on the adsorption capacity towards Alpacide Yellow. The optimal conditions for enhanced properties were found to be an impregnation ratio of 40 g/1 g, impregnation time of 6 h, and carbonization temperature of 400 degrees C. Despite its lower specific surface area compared to commercial activated carbon, the prepared activated carbon exhibited higher adsorption capacity due to the presence of pores and functional groups on its surface. The adsorption process followed a fractal kinetic model, while the adsorption isotherm model was stochastic.

Summary: This study proposes an enhancement mechanism based on enhanced constructive interference for microwave-assisted regeneration of activated carbons, which has been demonstrated to achieve high regeneration efficiency and reduced energy consumption. Through a series of experiments and numerical simulations, it was found that the reduced energy consumption is due to enhanced constructive interference controlled by dielectric properties.

Summary: The purpose of this study was to investigate the impact of lignocellulosic composition in biomass waste on the microstructure and dye adsorption characteristics of microwave-assisted -ZnCl2 activated carbon. The results showed that cellulose is responsible for pore formation, while lignin is responsible for the presence of functional groups and pore size. Activation using ZnCl2 coupled with microwave heating creates uniform pores, and the adsorption ability of the activated carbon increases with an increase in the impregnation ratio. The activated carbon with the highest cellulose content exhibited the best adsorption ability.

Summary: The robust development of electric vehicles has led to an increasing number of decommissioned lithium-ion batteries (LIBs), making the recycling of spent LIBs an urgent and essential task. However, current recycling methods only focus on valuable metals, resulting in a significant waste of valuable carbon material from the graphite anode. A simple strategy to efficiently obtain value-added products is crucial for the recycling of spent graphite.

Summary: The study synthesized low-cost zinc oxide nanoparticles (ZnO-NPs) with surfactant and ionic liquid molecules for the effective removal of Eriochrome Black T (EBT) from aqueous media. The adsorption of EBT followed Freundlich model and pseudo-second-order kinetics, with pore diffusion rate affected by surface modification. ZnO-NPs were successfully regenerated and reused, with their adsorption ability systematically explored in real wastewater samples and interference study of inorganic metallic salts.

Summary: Despite large investments in industries, energy conservation methods are lagging behind and industries are still searching for alternatives. This study presents an effective method of recovering sulfur and hydrogen from hydrogen sulfide using indirect electrolysis, with graphite as both anode and cathode and calomel as a reference electrode. The recovered sulfur showed a crystalline orthorhombic structure, and the maximum current density achieved was 0.41 A/cm(2). The quantity of sulfur recovered by indirect electrolysis was 2.9 mg with an efficiency of 90.44%.

Summary: In this study, mono- and bimetallic Pd and Pt catalysts were deposited via supercritical fluid reactive deposition (SFRD) on TiO2 coated additively manufactured substrates. The focus of this work was to evaluate the suitability of these catalysts for the direct synthesis of H2O2 in the liquid phase. The results showed that all catalysts exhibited high activity and productivity, with PdPt bimetallic catalysts showing the highest productivity and an increase in Pd loading leading to a decrease in productivity. Comparison with literature data demonstrated the high suitability of the SFRD method for the proposed application, with the added benefits of simplicity and environmental friendliness in catalyst production.

Summary: It is impossible to control the outer wall temperature of the micro-combustor below the maximum allowable temperature of commercial thermoelectric generators simply through increasing the equivalent heat transfer coefficient. Three simple strategies were developed to improve temperature uniformity, yet none of them could ensure full temperature control.
