Summary: In this study, ionogels containing microcrystalline cellulose (MCC) and Na-bentonite (Na-Bent) were synthesized using an ionic liquid solvent. The physicochemical properties of the synthesized materials were characterized and researched using various methods such as SEM, WAXS, thermal analysis, FTIR, conductometry, and viscometry. The results showed that the interlayer distance of Na-bentonite in the composites increased due to intercalation of the ionic liquid molecules. It was also found that the triple ionogels (IL/Na-Bent/MCC) exhibited enhanced thermal stability and the electrical conductivity of both triple and binary ionogels showed non-monotonous behavior.

Summary: Sulfide electrolytes with optimized LiI doping in the Li3PS4 structure exhibit high ionic conductivities, making them promising solid electrolytes for all-solid-state batteries. These sulfide electrolytes showed stable capacities and excellent cycling performance at 0 degrees C but experienced fast capacity decay at 60 degrees C. The electrochemical performance differences at different temperatures were attributed to interfacial resistance caused by volume changes. This study provides insights into the temperature effects on the electrochemical performance of all-solid-state Li-S batteries.

Summary: A liquid-liquid transition (LLT) is a transformation from one liquid to another through a first-order transition, fundamental to understanding the liquid state. While LLT has been reported in some materials, experimental evidence for its existence in many molecular liquids remains controversial. Studying the local order and structural dynamics across an LLT provides unprecedented possibilities for understanding the nature of the liquid state.

Summary: The separation of water and oil from water-in-oil emulsion is crucial for its transportation and refining. Ionic liquids and their derivatives have been studied as effective agents for breaking emulsions. In this study, microcrystalline cellulose grafted with imidazolium-based ionic liquids (MCC@IM-ILs) was synthesized and evaluated as eco-friendly surface-active agents for water separation from crude oil. The structure of the synthesized compounds was confirmed through various characterization techniques. MCC@IM-ILs showed acceptable dehydration efficiency to demulsify different water-in-oil emulsions. The concentration, alkyl chain length, and counter-anion of MCC@IM-ILs played a key role in the separation process.

Summary: Ionic liquids are considered the safest solvents in high-temperature applications due to their non-flammable properties, with thermogravimetric analysis being extensively used for studying their thermal stability. Isoconversional methods are found to be superior to Arrhenius methods in calculating activation energy, and the use of compensation effect and master plots is suggested for pre-exponential factor calculation. The structure of cations has some influence on thermal stability, but anions play a larger role. Developing dicationic ILs can lead to enhanced thermal stability.

Summary: New composite films were prepared by incorporating bacterial cellulose nanofibers and cerium oxide nanoparticles into chitosan matrices. The amount of nanofillers affected the structure and properties of the composites, including film stiffness and strength. Increasing the concentration of nanoceria improved the biocompatibility and adhesion of the films to mesenchymal stem cells. These nanocomposite films exhibit favorable properties for use as matrix materials in cell culture and wound dressings.

Summary: The enzyme-like activity of metal oxide nanoparticles is influenced by factors such as size, shape, surface chemistry, and substrate affinity. The size effect of ceria nanoparticles, a prominent inorganic nanozyme, is still not well understood. This study investigated the peroxidase-like activity of CeO2 nanoparticles with different sizes in different buffer solutions, and found that the size of the nanoparticles had different effects on their activity depending on the buffer solution used. The possible reasons for these differences are discussed.

Summary: Nanocrystalline cerium dioxide is a promising inorganic UV filter for sunscreen applications due to its high UV absorbance and non-toxicity to normal cells. Nanoscale CeO2 also showed selective cytotoxicity to cancer cells. Crystalline cerium(IV) phosphates can be a promising alternative for nanoscale CeO2 due to their low solubility, high redox stability and UV protective property. In this work, it was demonstrated for the first time that ceric phosphates have a comparable inhibitory impact on murine melanoma B16/F10 cell line to nanoscale CeO2 at high concentrations.

Summary: This work investigated the physicochemical properties and biological activity of nanoemulsions prepared from paraffin oil and stabilized by nonionic surfactants as carriers of curcumin and cerium dioxide nanoparticles. The results showed that curcumin was incorporated into the oil droplets while cerium dioxide nanoparticles were adsorbed on the surface of oil droplets. The nanoemulsion droplet size did not exceed 100 nm. The nanoemulsions demonstrated no toxicity to mouse embryonic fibroblasts in vitro and after a single intraperitoneal injection to mice in vivo, indicating their potential as drug carriers for advanced biomedical applications.

Summary: Excitation-emission matrix (EEM) fluorescence spectroscopy was used to quantify unmodified fullerenes C-60 and C-70 in different solvents at room temperature. The fluorescence intensity and parameters depend on the fullerene and solvent, allowing for quantification of mixtures without separation. The method was successfully applied to model and real mixtures of C-60 and C-70, with detection limits of 7 nmol/L and 2 nmol/L, respectively.

Summary: This study investigates the combined use of cold argon plasma (CAP) and metal oxide nanoparticles for antibacterial treatment. The results demonstrate that the combination of CAP and redox-active metal oxide or metal fluoride nanoparticles effectively inhibits bacterial growth, damages DNA, and disrupts the cell wall. The combination of CAP and CeF3 nanoparticles shows the strongest antimicrobial effect on plasmid DNA, while the CAP and WO3 combination is most effective against bacterial genomic DNA. CeF3 nanoparticles exhibit strong antimicrobial and DNA-damaging properties for the first time.
