Summary: In this study, a facile and large-scale synthesis of high-concentration 1T-TMDs using an ionic liquid assisted hydrothermal strategy was reported. It was found that the ionic liquid adsorbs on the surface of 1T-MoS2, inducing the formation of 1T-MoS2 through steric hindrance, pi-pi stacking, and hydrogen bonds. The obtained MoS2-IL showed high stability for 180 days at room temperature and exhibited excellent HER performance in acid conditions.

Summary: In this study, an ionic-liquid (IL) hydrogen-bonding promoted dihydrogen auto-transfer strategy was used for the amination of alcohols to higher amines over a cobalt catalyst under base-free conditions. The strategy demonstrated high performance and tolerance to a wide range of amines and alcohols, resulting in good to excellent yields of higher amines. The mechanism investigation suggested that the [BF4] anion played a key role in activating the alcohol and facilitating the transfer of hydrogen atoms to the cobalt catalyst, leading to the formation of aldehyde intermediates and cobalt dihydride complexes, which were involved in the subsequent reductive amination. This green and effective route for alcohol amination has potential applications in alcohol-involved alkylation reactions.

Summary: This study investigates binary liquid mixtures of 1-butyl-3-methylimidazolium glutamate acid ([bmim][glu]) with alkanols using an experimental and computational chemistry approach. The results provide insight into the properties and deviations from ideality of these complex liquid mixtures, as well as the effects of intermolecular forces and different types of alkanols. Theoretical studies using quantum chemistry and molecular dynamics simulations reveal nanoscopic characteristics of the fluids, particularly focusing on hydrogen bonding and its impact on molecular arrangements and mixed fluids' properties. This study contributes to the understanding of amino acid-based ionic liquid mixtures and the development of sustainable ionic liquid systems mixed with organic solvents for specific applications.

Summary: Ionic liquids (ILs) are often used in combination with polar solvents to modify their properties, and this study investigated the micro-heterogeneity and H-bonding interactions between a hydroxyl-functionalized IL and acetonitrile. The mixtures deviated from ideal behavior due to the newly formed H-bonding interactions, highlighting the importance of understanding the properties of IL-solvent mixtures for various applications.

Summary: This study proposes a strategy to directly fuse the functional attributes of small additives into supramolecular polyelectrolyte nanoporous membranes under ambient conditions. The pore size distributions and mechanical properties of the membranes are controlled by tuning the hydrogen bonding interactions between the additives and the polyelectrolyte. The study demonstrates that small dye additives/homo-poly(ionic liquid) solutions can be used as versatile inks to create colorful light emitting films with robust underwater adhesion strength, excellent stretchability, and flexibility on various surfaces.

Summary: In this study, we measured the enthalpies of vaporisation for a set of molecular and ionic liquids using modern techniques for vapour pressure measurements. We were able to avoid the decomposition problem at high temperatures by using the quartz crystal microbalance, thermogravimetric analysis, and gas chromatographic methods. By applying group contribution methods for molecular liquids and the centerpiece method for ionic liquids, we were able to analyse the enthalpies of vaporisation and understand different types of molecular interaction in the liquid phase.

Summary: Polymer electrolyte membranes with acid infiltration and different nanophase-separated structures were studied for their mechanical properties and proton conductivities. Lamellae-forming S-P-S/H2SO4 membranes showed higher tensile strength than sphere-forming S-P-S/H2SO4 membranes, even with the same amount of H2SO4 infiltrated. However, the conductivities of lamellae-forming membranes were comparable or superior to those of sphere-forming membranes, due to the acid/base stoichiometry associated with acid-base complex formation.
