Summary: Extractive desulfurization using ionic liquids has attracted attention due to its simplicity and easy operating conditions. However, the selection of suitable cations and anions remains a challenge. This study developed a methodology to screen cation and anion molecules for maximum sulfur removal efficiency. Through genetic algorithm and principal component analysis, it was determined that certain imidazolium and pyridinium cations combined with specific anions are promising for extractive desulfurization. The selected ionic liquid, [HMPY][N(CN)2], was synthesized and evaluated, showing potential as a solvent for removing DBT or BT from n-heptane.

Summary: We investigated the sodium electrochemistry and the evolution and chemistry of the solid-electrolyte interphase (SEI) during cycling of Na metal electrodes in two ionic liquid (IL) electrolytes. We found that the IL based on the phosphonium cation demonstrated superior performance and stability compared to the pyrrolidinium-based counterpart, even after the addition of water.

Summary: The aim of this study is to develop an environmentally friendly and effective method for the extraction of nutritious date sugar using natural deep eutectic solvents (NADES) and ultrasound-assisted extraction (USAE). The best performing NADES was synthesized using choline chloride (ChCl), citric acid (CA) and water in a ratio of 1:1:1 with 20 wt% water, resulting in a sugar yield of 78.30 ± 3.91 g/100 g. Further optimizations using response surface method (RSM) and artificial neural network (ANN) led to a sugar recovery of 87.81 ± 2.61 g/100 g. The NADES-USAE method showed a 43.1% higher sugar yield compared to conventional hot water extraction (CHWE). This study presents a promising approach for extracting nutritive sugars from dates using environmentally friendly solvents and advanced technology, while preserving the bioactive compounds.
