Summary: The study investigated the role of imidazolium Gemini ionic liquids (ILs) in controlling the swelling and dispersion of Na-montmorillonite (Na-Mt). The length of alkyl chains was found to affect the swelling behavior and particle size, with hydrophobicity playing an important role in increasing the stability of modified Mt in water. Experimental results confirmed the ion exchange and adsorption mechanism between imidazolium Gemini ILs and Na-Mt, and determined the molecular arrangement and intercalation.

Summary: A PVDF/IL-Na+MMT composite membrane with excellent hydrophilic performance and antifouling properties was successfully prepared in this study, which can simultaneously remove dye wastewater and oil-water emulsion. The modified membrane exhibited excellent hydrophilicity and lipophobicity, achieving high separation performance with a processing capacity of 320.76 (L·m-2·h-1), and excellent removal efficiency for both anionic and cationic dyes at over 90%, as well as superb rejection of oil-water emulsions. Moreover, the modified membrane showed superior sustainability, with a FRR of 95.4% for anionic dyes, 88.3% for cationic dyes, and 95% for oil-water emulsions after two cycle tests. The PVDF/IL-Na+MMT membrane is of great significance in solving practical application problems related to treating oil-water emulsion and dye wastewater.

Summary: Porous ionic liquids (PILs) are used for removal of trace impurities and conversion of captured H2S in natural gas purification. These PILs have exceptional selectivity in enriching H2S from CO2 and CH4, while UiO-66-OH's permanent pores store a higher amount of selectively captured H2S. The tertiary amines in PILs act as catalysts for the conversion of stored H2S into 3-mercaptoisobutyric acid, a key intermediate for the synthesis of the antihypertensive drug Captopril.

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.
