Summary: Concerns over heavy metals in wastewater and their impact on the environment and human health can be addressed through adsorption technology. This study developed efficient and cost-effective adsorbents, specifically chitosan-grafted polyacrylonitrile/ZnO, for the treatment of water contaminated with heavy metals. Various tests confirmed the morphological and structural properties of the materials, and the adsorption behavior of Fe(II) ions was studied. The adsorption process followed the Langmuir model and pseudo-second-order kinetics, suggesting a monolayer formation of Fe(II) over the adsorbent surface.

Summary: In this study, a composite SCX-37 biosorbent, made by mixing natural sepiolite and Cavex CA37 at certain ratios, is used for the biosorption of UO2+ (2) ions from a synthetic aqueous solution. The biosorption process is influenced by solution pH, ambient temperature, contact time, and UO2+ (2) ion concentration. The biosorption of UO2+ (2) ions on SCX-37 reaches equilibrium in 120 min with 97.56% efficiency at 30 degrees C and pH 4. The isotherms and thermodynamic values of the biosorption process are calculated, showing a high correlation between experimental results and all three isotherm models. The adsorption capacity is 41.39 mg g(-1) and the adsorption energy is 40.50 kJ mol(-1).

Summary: The transport of heavy metals to groundwater depends on soil characteristics such as carbonate and clay minerals, organic matter content, soil pH, etc. Most heavy metals in calcareous soils are precipitated as metal carbonate minerals, so their transport to groundwater is not expected. This study focuses on the adsorption and transport of lead (Pb) and copper (Cu) in calcareous soil in the presence of calcium carbonate.

Summary: This study used graft copolymerization to modify acid-washed Madacamia nutshell biomass with diethylenetriamine (DETA) and maleic anhydride (MA). The modified biomass contained polar and ionizable groups that were capable of adsorbing and removing hexavalent chromium (Cr(VI)) from aqueous solutions. Adsorption efficiency ranged from 70.9% to 81.7% over a wide pH range. The adsorption isotherm data fit the Freundlich model and the Sips isotherm model provided the best fit. The study demonstrates the potential of using DETA and MA modified Madacamia nutshell biomass for the removal of Cr(VI) from aqueous solutions.

Summary: Heavy metal exposure from wastewater is a global environmental issue. Biosorption is a promising alternative for contaminant removal. This study investigated the operation parameters and biosorbent regeneration for copper adsorption. The results showed that Durvillaea antarctica algae had a higher copper retention capacity at pH 4.5-5.0, and sulfuric acid was the most efficient regenerating reagent. Particle size of 1.70-3.36 mm and a biosorbent mass-to-volume ratio of 10 g L-1 were desirable for diluted copper solutions (10 to 100 mg L-1).

Summary: Mechanisms contributing to high carrier/electron mobility in oxide/SrTiO3 heterostructures have been investigated. It is found that the formation of a conducting substrate surface layer (CSSL) on STO substrate plays a critical role in enhancing the conductivity of LSTO/STO heterostructures. This CSSL is formed when an oxide layer (LSTO) is grown on STO, indicating that the oxide layer actively pulls oxygen from the substrate, leading to the formation of the CSSL. Oxygen transfer across the film/substrate interface during the synthesis of oxide heterostructures is emphasized as a critical factor in functional properties.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
