Summary: This study investigates the influence of cosurfactant hydrophobicity on the formation of cerium tetrafluoride nanoparticles in water-in-oil microemulsion. The results show that the synthesis of nanostructures occurs in three stages for both types of microemulsions. The use of 1-butanol as cosurfactant leads to faster reaction, while longer hydrophobic chain length of 1-hexanol results in the formation of smaller hexagonal nanorods.

Summary: This study investigates the phase behavior of surfactant-free microemulsions (SFMEs). It reveals the formation of microemulsions without traditional surfactants in the ternary mixture of n-butanol, ethanol, and water, and identifies three types of microstructures, including oil-in-water, bicontinuous, and water-in-oil structures.

Summary: The study aimed to investigate how fructose increases ethanol metabolism rate in the liver, attributing this effect to the consumption of NADH rather than stimulation of mitochondrial re-oxidation through ATP consumption. Ethanol oxidation in rat hepatocytes was significantly increased by fructose, sorbose, and accompanied by changes in metabolites like glucose, glycerol, lactate, and sorbitol.

Summary: In this study, multiple bacterial strains were isolated from soil and water, screened for glutaminase-free L-asparaginase activity, and purified for further characterization. The optimal working pH for purification was found to be 8.6, resulting in a purity level of 99.2% for the L-asparaginase enzyme. This developed purification process and characterization could be instrumental for naturally occurring enzymes, as most current processes focus on recombinant enzymes.

Summary: Photo differential scanning calorimetry (photo-DSC) is suitable for characterizing photopolymers in additive manufacturing, providing important process parameters with careful sample preparation. Different sample shapes, masses, and preparation times were investigated in this study, showing the impact on experimental results and the importance of selecting appropriate sample shapes and handling methods for reliability.

Summary: Mesoporous carbon was synthesized as a support for PtRe anodic electrocatalysts. The addition of Re decreased the CO oxidation onset potential value, and the PtRe(3)/MC catalyst exhibited the best electrocatalytic activity.

Summary: Different methods were used to study the kinetics and mechanism of resorcinol-formaldehyde (RF) condensation, yielding significantly different results and applicability. Fourier transform infrared spectroscopy (FTIR) can only track the changes in functional groups at the early stages of the reaction. Dynamic light scattering (DLS) can estimate the growth of particles in the reaction solution before it becomes more viscous. H-1 nuclear magnetic resonance relaxometry (H-1-NMR) provides insights into the properties of water present in the polymeric gel during RF condensation. Differential scanning calorimetry (DSC) measurement of the freezing/melting behavior of the reaction mixture has the widest range of applicability. These findings can enhance our understanding of the mechanism of RF condensation.

Summary: This study investigates the phase transition behavior of differently crosslinked PNiPAM/BIS microgels with aromatic additives, and analyzes the influence of model drugs on VPTT. The results show that VPTT increases with crosslinker content, accompanied by a drastic decrease of transition enthalpy. The presence of an additive generally decreases VPTT, but with distinct differences concerning the crosslinker content.

Summary: The study focused on the behavior of the solubility of Hydroxytyrosol (HXT) in binary solvent mixtures and its thermodynamic properties. The solubility of HXT in different solvents and the thermodynamic properties of its dissolution were measured and predicted using various analytical methods. The preferential solvation of HXT was determined using the inverse Kirkwood-Buff integral theory.

Summary: A new type of silver nanoparticles (AgNPs) with good stability and narrow size distribution was prepared and studied. They were mixed with a non-toxic hydrogel, and no significant interaction between AgNPs and the hydrogel was observed. Furthermore, the AgNPs showed low biological activity against various cells and organisms, indicating their potential for drug delivery applications.

Summary: The study investigates the production of surfactant-free microemulsion hybrid biofuels using oil extracted from halophytic salicornia plants that can grow in highly saline lands and tolerate seawater salinity, as a replacement for fossil fuels. The results show that salicornia oil exhibits good low temperature phase behavior and is suitable for biofuel formulation. Characterization of the nanostructures of the produced biofuels reveals the effect of additives on the ethanol in oil structure.

Summary: The research focuses on investigating the effect of different ceria support preparation methods on Ni active phase stabilization for ethanol steam reforming to produce hydrogen. Catalysts prepared by precipitation method showed higher reducibility and more homogeneous Ni particle size distribution, leading to lower coke deposition rate and making them more stable catalysts for the reaction.

Summary: This study investigated the anti-proliferation potential of extracts from carrot, Calendula officinalis flower, and Aloe vera on breast cancer vs. epithelial cell lines. The extracts were able to specifically inhibit the proliferation of breast cancer cell lines, and the different lipid compounds in the extracts may be associated with their observed different anti-proliferative properties.

Summary: The study focused on predicting the efficiency of micellar solubilization using biosurfactants, and successfully created a model using evolutionary algorithms and kernel support vector machines. The model showed that the molar solubilization ratio (MSR) can be accurately predicted, ranking the parameters influencing solubilization efficiency. This research represents the first attempt in literature to predict MSR using the MSR calculator delivered as a result of the study.

The selected oils and glycols composition resulted in microemulsions with reduced surfactant content and improved safety as delivery systems.
