Summary: Cell cryopreservation is essential for long-term storage, but some cell lines cannot be efficiently cryopreserved. Research shows that a synthetic zwitterion solution can achieve good cryopreservation, but not with high efficiency for certain cells. Further study on the cryoprotective effects and mechanisms of zwitterions is needed for optimization and better results.

Summary: During long-term cell storage, the addition of cryoprotectants to inhibit ice crystal formation is necessary. However, the high osmotic pressure and dehydration caused by non-cell-permeable cryoprotectants often damage cells. In this study, researchers developed a poly(zwitterion) isotonic cryoprotectant that forms a firm matrix around cells, preventing the influx of ice crystal nuclei without the need for high osmotic pressure and dehydration.

Summary: Solubility in water, interactions with the solvent medium, and tuning of molecular conformation in the liquid phase are crucial for the discovery of new biologically active molecules and the understanding of their mechanisms. This article presents the synthesis, structural and biological activity studies, and computational modeling of new ionic compounds. Combining the structural frameworks of well-known imidazolium, pyridinium, and cholinium ionic liquids with naturally occurring cinnamic acid allows for the modulation of solubility, physicochemical properties, and biological activity. The biological activity of the resulting molecules was significantly increased, and the structure-activity relationship was investigated through cytotoxicity mapping and molecular dynamics simulation.

Summary: Transition metals are crucial in fine organic synthesis, but their toxicity and environmental pollution have raised concerns. The comparison between supported catalysts and soluble metal complex catalysts revealed that supported catalysts have lower cytotoxicity, but their overall impact on the environment can vary depending on the preparation procedure and may have neglected biological effects. Both types of catalysts did not significantly contribute to the overall toxicity of the systems, while commonly ignored byproducts showed higher overall biological influence.

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: This study investigates the influence of the flexible spacer parity of a guest photoactive liquid crystalline dimer on the photonic bandgap features of the cholesteric and twist grain boundary smectic C phases of the host molecule. The results show that the parity of the photoactive dimer affects the width of the photonic bandgap and the blue-shift of the cholesteric phase. Additionally, the parity of the dimer also affects the layer spacing and two-dimensional periodicity of the liquid crystalline phases.

Summary: This work focuses on the thermochemistry of solvation of azeotropes. The enthalpies of dissolution of azeotropes in different mediums were determined, and the impact of the structure of the azeotropes on their properties in solution was discussed. A correlation between enthalpies of solvation and molar refraction was used to determine the vaporization enthalpies of azeotropes for the first time. The results were found to be consistent with literature data, obtained using direct and calculated methods. These findings contribute to the analysis of the structure-property relationships of azeotropes.

Summary: In this study, the interactions between doped and pristine coronenes and adenine nucleobases were investigated using Density Functional Theory. The optimal configurations, adsorption energies, charge transfer, and electrical properties of each complex were calculated. It was found that doped coronene had stronger adsorption strength and charge transfer compared to pristine coronene. The stability of the complexes was attributed to non-covalent interactions in the interactive region. The change in electrical conductivity of coronenes after adsorption suggested their sensitivity towards DNA bases. The predicted energy gap and prolonged recovery time for adenine-coronene configurations indicated the potential application of pristine/doped coronene in DNA detection.

The reaction mechanism involves complex reaction orders for the oxidant and the aromatic aldehyde, while the reaction order for Ru(VI) is one. The proposed mechanism includes two catalytic cycles and the formation and decomposition of complexes.

Summary: This study evaluated the adsorption of zolpidem on magnetic graphene oxide and synthesized magnetic graphene oxide adsorbents for zolpidem removal. The best magnetic nanoadsorbent was found to have a removal percentage of 87.07% at specific pH and temperature conditions. The results suggest that the removal of zolpidem is related to the surface chemistry of the adsorbent rather than the surface area of graphene oxide. The adsorbent showed excellent adsorption efficiency and magnetic behavior, making it a promising material for removing zolpidem from aqueous solutions.

The results show that volume fraction and temperature have a significant impact on the thermal conductivity, while sphericity also needs to be considered. A support vector machine regression model was created to analyze the sensitivity of the thermal conductivity to different parameters. The findings indicate that temperature, sphericity, and volume fraction are the most sensitive variables.
