Summary: Ionic liquids (ILs) have unique properties that make them promising candidates for biomedical applications, but their cytocompatibility limitations are enhanced by using bioionic liquids (BILs) derived from biological molecules. BILs can be synthesized and immobilized onto biopolymers, and their functionalization enables the design of responsive actuators and sensors. The cytocompatibility of BIL-functionalized polymers also makes them suitable for power storage and implantable devices. This review focuses on the recent advances of BILs in biomedical applications, specifically their use as functionalization agents for biopolymers and solvents for supermolecular ionic networks.

Summary: In this study, the use of N,N-dimethylcyclohexylamine as a switchable-hydrophilicity solvent for the absorption of toluene showed excellent performance in separation processes. By bubbling CO2 and N-2, efficient desorption and separation were achieved, and the absorption capacity of the solvent remained comparable even after multiple cycles. This innovative and reversible remediation strategy utilizing switchable-hydrophilicity solvents has the potential to be a more environmentally friendly and energy-efficient alternative to traditional absorbents for reducing VOC pollution.

Summary: This study reports the preparation of a catalytic system designed to respond adaptively to feed gas composition in hydrogenation reactions. Ruthenium nanoparticles immobilized on amine-functionalized polymer-grafted silica act as active and stable catalysts for the hydrogenation of biomass-derived furfural, acetone, and related substrates. The formation of alkylammonium formate species at the amine-functionalized support triggers the selectivity switch in the catalytic reaction, with the catalyst performance responding almost in real time to the feed gas composition.

Summary: Ruthenium nanoparticles immobilized on an amine-functionalized polymer-grafted silica support can selectively catalyze the hydrogenation of bicyclic heteroaromatics. The addition of CO2 to the hydrogen gas phase can effectively shut down the arene hydrogenation reaction while maintaining activity for heteroaromatic hydrogenation. This selectivity switch is achieved through the catalytic generation of ammonium formate species on the material's surface by hydrogenation of CO2. By altering the composition of the feed gas, a variety of benzofuran and quinoline derivatives can be selectively hydrogenated to fully or partially saturated products using a single catalyst.

Summary: PDO can be produced by fermenting glycerol, but separating it from the aqueous medium is difficult. A new method called Solvent-Assisted Switchable Water (SASW) is proposed. In this method, a hydrophilic solvent is used to extract PDO from water, while a CO2-switchable ionogen prevents the solvent from merging with the aqueous phase. The extraction yield was 73%, but the extracted PDO contained water and amine, indicating that further improvement is needed for selective extraction.

Summary: CO2-responsive materials undergo changes in their properties when CO2 is introduced or removed. CO2 is advantageous as a stimulus due to its abundance, benign nature, affordability, and lack of accumulation in a system. Various CO2-responsive materials such as polymers, latexes, surfactants, and catalysts have been explored. CO2-responsive gels, a subset of CO2-responsive polymers, have unique changes such as swelling or transformed morphology. This paper reviews the preparation, properties, and applications of CO2-responsive gels, including nanogels, microgels, aerogels, and macrogels, and also discusses CO2-induced self-assembled gels.

Summary: Switchable materials, especially CO2-switchable materials, are of great interest in environmental research. Replacing non-switchable materials with switchable counterparts has the potential to make processes more environmentally friendly by enhancing reusability and circularity, reducing energy costs and material consumption. This study focuses on the surface and foaming properties of aqueous solutions containing a non-switchable surfactant and a CO2-switchable additive. The results show that the additive can change surface properties, foamability, and foam stability when switched with CO2.

Summary: Volatile organic solvents are widely used in various industries, but their emissions, inhalation risks, and flammability pose significant concerns. Switchable-hydrophilicity solvents (SHS), which can switch between water-miscible and water-immiscible states, offer a solution to these issues. Anionic SHS (ASHS) systems, composed of hydrophobic carboxylic acid and water-soluble base, provide a new variation of SHS. This study reports the development of a low-toxicity SHS without the need for excess water, using branched carboxylic acids and substoichiometric amounts of NaHCO3 or NaOH.

Summary: Biomass conversion to organic products is crucial for a sustainable society, but current energy costs and environmental impacts, particularly in removing water, remain problematic. The new method of high pressure switchable water (HPSW) shows promise in more efficiently separating organic products from water by changing the polarity of organic liquids and utilizing CO2 pressure.
