Summary: Intensive research efforts have focused on reducing toxic Cr(VI) to less toxic Cr(III), but many methods end up with improper removal or recurrence. This study characterized the biospheric bacterial community using Metagenomics and elucidated the bio-mechanisms behind the reduction of Cr(VI) to Cr(III) by FeS particles. The BEER approach effectively removed Cr and Fe in contaminated soil, with sulphide content enhancing Cr reduction and removal.

Summary: Copper and nickel can be effectively extracted through medium-temperature sulphate-based pressure leaching, with copper extraction reaching over 99% under favorable conditions. The extent of sulphate formation depends on temperature, acidity, and agitation. Iron hydrolysis can remove iron from the solution, while noble metals appear to remain in the residue.

Summary: Copper dump leaching involves irrigating run-of-mine ore with acidic solution to generate aqueous cupric ions. Despite the large size of the ore particles being leached, the process is effective due to particle breakage, continuous generation of fines, and fresh mineral surfaces for leaching. The rate of copper leaching in dumps is determined by the rate of fines generation and leaching of the fines.

Summary: The present study synthesized two new materials, MWCNT-OH-Mag and MWCNT-COOH-Mag, by functionalizing multi-walled carbon nanotubes (MWCNT) with magnetite (Fe3O4) using solution precipitation methodology. These materials were characterized using various techniques and showed effective impregnation and regular distribution of nanoparticles on the surface. Batch studies indicated that MWCNT-OH-Mag exhibited superior adsorption performance for 2,4-D and Atrazine pollutants, with optimal pH conditions of 2 and 6, respectively. The adsorption kinetics reached equilibrium within 30 minutes, and the Sips model accurately described the adsorption isotherms. The synthesized materials demonstrated high stability in aqueous solutions and showed promising potential for water purification through adsorptive separation.

Summary: This study reports the synthesis of magnetic graphene oxide (GO Fe3O4) with different amounts of iron nanoparticles for the adsorption of furosemide (FUR). The optimal adsorbent was found to be GO Fe3O4 1:1, with a removal percentage and adsorption capacity of 96.15% and 96.91 mg g-1, respectively, at pH 3.0 and 293.15 K. The process was influenced by initial concentration, adsorbent dosage, and pH, while the ionic strength had minimal effect on the performance of GO Fe3O4 1:1. Sips and PSO models were the best fit for the experimental data, indicating a heterogeneous surface. GO Fe3O4 1:1 exhibited high removal percentage even after several cycles of adsorption/desorption.

The adsorption study revealed that the clay has typical bentonite characteristics and can effectively adsorb Gd3+. The kinetics and thermodynamics of the adsorption process were analyzed, and it was found that the Langmuir model and Avrami fractional order model were suitable for describing the adsorption isotherms and kinetic data, respectively. The study also showed that citric acid was an efficient desorbing agent for Gd3+ from the bentonite, and the clay could selectively recover Gd3+ from the real leachate of phosphogypsum.

Summary: This study investigated the adsorption and recovery of cerium (Ce(III)), a rare earth element, from an aqueous solution using a sustainable hydrochar made from wood waste. The hydrochar contained various surface functional groups, which significantly influenced its adsorption capacity. The pH of the solution strongly affected the Ce(III) removal, with the highest removal efficiency achieved at pH 6.0. The hydrochar exhibited high efficiency in Ce(III) adsorption, with a maximum adsorption capacity of 327.9 mg g(-1) at 298 K. The adsorption kinetics followed the general order model, while the equilibrium process fit the Liu isotherm model. The Ce(III) adsorption mechanism on the hydrochar involved electrostatic interactions and chelation between surface functional groups and Ce(III). The hydrochar also demonstrated excellent regeneration capacity using sulfuric acid as an eluent. This research presents a sustainable approach for developing an efficient adsorbent for Ce(III) removal with excellent physicochemical properties.

Summary: Due to its toxicity, Cu(II) ions released in aquatic environments pose a serious threat to the environment and human health. Citrus fruit residues can be utilized to produce activated carbons as sustainable and low-cost alternatives. In this study, eight activated carbons were developed from orange peel, mandarin peel, rangpur lime peel, and sweet lime peel, using CO2 and H2O as activating agents. These activated carbons exhibited promising adsorption properties for Cu(II) ions, with a micro-mesoporous structure, a specific surface area of around 400 m(2) g(-1), and a pore volume of around 0.25 cm(3) g(-1). The adsorption process was favored at pH 5.5 and reached equilibrium within 60 minutes, removing approximately 80% of Cu(II) ions. The Sips model provided the best fit to the equilibrium data, with maximum adsorption capacities ranging from 67.83 to 88.04 mg g(-1) for different activated carbons. The thermodynamic behavior indicated that the adsorption process was spontaneous, favorable, and endothermic. The mechanism was suggested to be controlled by surface complexation and Cu2+-pi interaction. Desorption of Cu(II) ions was possible using a 0.5 mol L-1 HCl solution. The results of this study demonstrate that citrus residues can be effectively utilized as adsorbents for the removal of Cu(II) ions from aqueous solutions.

Summary: Climate change is a progressive phenomenon that cannot be stopped, only mitigated. This poses a challenge in proposing resilient design strategies due to the high level of uncertainty. The collection of climatic data for specific locations is also limited. In this study, a cycle of measurements was conducted in a social housing case study in Tunja, Colombia to analyze and validate the reliability of the collected data. Descriptive statistical analysis revealed acceptable average reliability but data below the minimum acceptability value, highlighting the importance of reducing uncertainty in resilient design.

The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
