Summary: This study investigated the cytotoxicity of chemically relevant imidazolium PILs with different alkyl side chains and compared it with aprotic analogues. The results highlighted the role of anion type in determining the cytotoxicity of ILs with short alkyl side chains. Even low-toxic PILs showed harmful effects on eukaryotic cells when used as cryopreservation agents, and the studied IL/water mixtures tended to form simple solid hydrates due to the weak amphiphilic properties of imidazolium cations with short alkyl side chains.

Summary: Rechargeable batteries utilizing redox-active organic compounds are being seen as a promising energy storage technology for the future. By functionalizing redox-active groups onto conducting polymers to create conducting redox polymers (CRPs), the low conductivity and dissolution issues of redox-active compounds can be effectively addressed. Through innovative techniques such as postdeposition polymerization, high-performance CRPs have been developed and optimized to achieve theoretical capacities, resulting in the creation of an efficient all-organic proton battery with impressive capacity retention.

Summary: The origins and behaviour of specific ion effects have been extensively studied in water and nonaqueous molecular solvents. However, the impacts of specific ion effects on more complex solvents, such as nanostructured ionic liquids, are still unclear. This study hypothesizes that the influence of dissolved ions on the hydrogen bonding in nanostructured ionic liquid PAN constitutes a specific ion effect.

Summary: Protic ionic liquids (PILs) are efficient pretreatment agents for lignocellulosic biomass deconstruction to produce ethanol. Optimal conditions for pretreatment include 2 hours, 150 degrees Celsius, 15% solids loading, and 20% water content. The addition of hemicellulases during saccharification can improve hemicellulose yield, while the use of ethanol and other antisolvents does not increase sugar yields.

Summary: The synthesis of large libraries of ionic liquids (ILs) allows for customization and study of their physicochemical properties. Ion structure modification can be systematically carried out to tailor ILs for specific applications, and the relationship between structure and properties can be explored. Various factors, such as ion stoichiometry, water content, ion reactivity, and ion clustering, contribute to the properties of ILs. This study investigates the physicochemical, thermal, and liquid nanostructure properties of 52 stoichiometric ion combinations and emphasizes the importance of reproducible synthesis methods and detailed characterizations. Machine learning algorithms are applied to provide quantitative insights into the contributions of different structural moieties. Comprehensive IL characterization and detailed reporting of preparation methods are highlighted for reliable experimentation.

Summary: The diffusion of ethylammonium nitrate within pores of two types of porous glass, Vycor and Varapor, was studied using H-1 NMR. The diffusional behavior of the ionic liquid is influenced by the tortuosity of the porous system in Varapor, while in Vycor, interaction with the pore walls leads to a lower diffusivity.

Summary: The study found that increasing the water concentration as a cosolvent can reduce the amount of ionic liquid used in biomass fractionation, achieving effective deconstruction for certain biomass types. However, softwood biomass showed higher resistance to fractionation at higher water concentrations. Additionally, reducing the amount of water used as an antisolvent can impact lignin precipitation yields and properties.

Summary: Surface area estimation using the BET analysis has been challenging, but a statistical thermodynamic generalization of the BET analysis has been proposed. A general isotherm was derived from the statistical thermodynamic fluctuation theory, which simplifies the fitting process. The reinterpretation of the monolayer capacity and the BET constant has led to a more comprehensive understanding of sorption cooperativity in porous materials.

Summary: The dynamics of long-term phase separation in binary liquid mixtures are studied by tracking the evolution of size, defect, and mesogen alignment in a binary liquid mixture with a confined liquid crystal-rich droplet. Visualizing the liquid crystal droplet configuration through polarisation microscopy, the research compares experimental findings with computational simulations and explains the differences between bulk phases and confined droplets based on the respective thermodynamics of phase separation. The work provides insights into how phase transitions on the microscale deviate from bulk phase diagrams and has relevance to other material systems.

Summary: More than 100 isotherm models exist for the six IUPAC isotherm types currently, but when different models claiming different mechanisms can fit an experimental isotherm equally well, no mechanistic insights can be reached. Popular isotherm models, like Langmuir, are often applied to complex systems that break their basic assumptions. To overcome this issue, a universal approach has been established to model all isotherm types, attributing the difference to sorbate-sorbate and sorbate-surface interactions systematically.

Summary: This article presents a universal theory of cooperativity in sorption isotherms using statistical thermodynamics principles. The excess number relationship is used to capture the cooperativity of sigmoidal and divergent isotherms, and is combined with the characteristic relationship to derive isotherm equations. These cooperative isotherm equations can be used to fit experimental data with a statistical thermodynamic interpretation of the parameters.

Summary: The availability of microbial genome sequences is helpful for identifying new microbial enzymes, particularly genes encoding proteins involved in extracellular processes. Proteomic analysis of secretomes is challenging, but a workflow that combines localization prediction and secretion prediction has been designed and applied to a fungal genome. The workflow produced three secretomes with increasing levels of stringency, showing increases in functional annotations for extracellular processes and reductions in annotations for intracellular processes. Multiple sequences isolated as part of the secretome lack functional annotation, making them potential candidates for novel enzyme discovery.

Summary: This study experimentally explored the impact of salt doping on the hydrotropy phenomenon and revealed the site-specific interactions between the hydrotrope and solute. The results showed that the pre-aggregation of the hydrotrope is detrimental to the hydrotropic effect, indicating that solute-induced clustering of the hydrotrope is the predominant mechanism of hydrotropy.

Summary: Inspired by the recently proposed cooperative mechanism of hydrotropy, this work investigates the impact of apolar volume and polar group position on the performance of hydrotropes. The results show that the size of alkyl chains has a significant impact on the ability of hydrotropes to enhance solubility, while the relative position of hydroxyl groups has a smaller effect. Contradictory findings at different hydrotrope concentrations are resolved using theoretical and experimental techniques, revealing that self-aggregation negatively affects the performance of hydrotropes.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
