Summary: Ionic liquids and deep eutectic solvents are widely used neoteric solvents. By adding acetic acid to 1-Ethyl-3-methylimidazolium chloride, the transition from the original ionic liquid to a eutectic mixture of EMIMCl and AcOH can be promoted. The study investigated the effects of this transition on cellulose regeneration and EMIMCl recovery, and demonstrated the potential application for obtaining highly acetylated cellulose.

Summary: The study showed that ionic liquids, specifically [BMIM][Br] and [BMIM][MeSO4], have different effects on the structure and function of Chloroperoxidase (CPO) depending on their concentrations. Low concentrations maintain enzyme activity while high concentrations alter enzyme structure and reduce flexibility of residues. The influence of [BMIM][MeSO4] on CPO structure is noted to be greater due to the unique structure of its corresponding anion group. Additionally, the number of cavities in the enzyme structure explains the activation and deactivation of the enzyme at different ionic liquid concentrations.

Summary: This study investigated the dissolution of microcrystalline cellulose (MCC) in binary solvent mixtures of ionic liquids (ILs) and molecular solvents (MSs). Experimental results and molecular dynamics simulations showed that the composition of the solvent mixture and the temperature influenced the dissolution of MCC. The simulations revealed that the hydrogen bonding between the hydroxyl groups of the cellulose and the ions of the IL played a significant role in the dissolution process. The study suggests that molecular dynamics simulations can be used to predict optimal solvents for cellulose dissolution.

Summary: Recent research has shown that methylimidazolium ionic liquids (MILs) are contaminating the environment and leading to exposure in the general population. This study examined the potential for MILs to cause cardiac toxicity and found that increasing alkyl chain length in MILs resulted in increasing adverse effects on rat neonatal cardiomyocytes. Further studies in rats confirmed the cardiotoxicity of MILs based on histopathology and clinical chemistry endpoints. It was also found that mice may be less sensitive to cardiotoxicity from MILs due to increased excretion via higher levels of cardiac BCRP expression and/or function.

Summary: A novel ionic liquid, [DBUC8]Cl, was synthesized and found to have stronger alkalinity than other imidazolyl ionic liquids, enabling more efficient dissolution of cellulose. Highly substituted cellulose acetate (CA) was successfully synthesized under mild conditions without the use of a catalyst, and a transparent cellulose acetate film (CAF) was obtained. The new DBU-derived ionic liquid offers a versatile platform for sustainable and efficient production of cellulose-derived bioplastics.

Summary: Inspired by temperature sensors in mammals, researchers have developed a photothermal-controlled nanochannel membrane that is sensitive to temperature changes. The nanochannels can be controlled by adjusting ion flux and osmotic energy conversion, and the temperature-induced structural changes in molecules contribute to the variations in rectification ratio at different temperatures. This system also demonstrates high efficiency in energy harvesting through osmosis.
