Summary: This publication presents the achievement of partial surface tension properties of liquids using an adapted Good-Girifalco approach. The results show that the interfacial tension data of water is suitable for estimating the dispersive component of surface tension, while the interfacial tension of squalene is more accurate for calculating the polar component. The proposed method strengthens the relationship between solubility parameters and surface tension parameter, which is of great importance for the field of Materials Science.

Summary: This study investigated the relationship between ectopic fat distribution and metabolite profiles induced by high-fat diets in rats. Visceral fat was found to have the strongest correlation with blood cholesterol levels, while liver fat content showed high correlation with specific metabolites like (-CH2)(n) VLDL/LDL and lactate. Five potential metabolic biomarkers were identified to differentiate between high-fat diet and normal diet groups.

Summary: This study analyzes the dynamic adsorption of surfactant from a micellar solution to a rapidly created surface. The model considers the adsorption of surfactant monomers, rather than micelles, on the surface. The results show the formation of a micelle-free region near the interface, which expands over time. The system reaches a state of full local equilibrium in the final stage.

Summary: The interaction between industrial ladle lining bricks and secondary metallurgical slag varied based on the slag composition and temperature, leading to different wear behavior and chemical reactions. The viscosity, MgO saturation, and carbothermal reactions in slag played key roles in infiltrating the lining material. Impurities in the lining material contributed to the formation of a liquid slag phase, compromising material strength and causing loss of MgO grains.

Summary: The surface energies (gamma), Hansen solubility parameters (HSP), and cohesive energy density are related. Modifications of solid surfaces can affect the surface properties, such as energy and adhesion characteristics, as well as HSP. In membrane technologies, the use of multi layered membranes like TFC is common, but it is difficult to selectively determine the HSP for the surface or top layer of a membrane.

Summary: The interaction between dodecyltrimethylammonium bromide (DTAB) and crystal violet (CV) was studied in aqueous solutions of short chain alcohols (ethanol, 1-propanol) and urea using the conductometric method. The critical micelle concentration (CMC), counter ion binding (p), and thermodynamics parameters (AG0m, AS0m, and AH0m) were determined for the DTAB + CV system. The CMC values increased with the concentration of alcohols and urea as well as with temperature. The micellization process was found to be thermodynamically spontaneous, with hydrophobic and electrostatic interactions playing a significant role in the interaction between DTAB and CV.

Summary: The synergistic interaction between surface-active ionic liquid and pluronic/non-ionic surfactant has been investigated, and it was found that the mixed system has significantly lower critical micelle concentration values compared to pure amphiphiles due to the strong attractive interaction between components. The mole fractions of the components and interaction parameter were determined using regular solution theory, and thermodynamic parameters were calculated. UV-visible spectroscopy confirmed the positive interaction between the ionic liquid and non-ionic surfactants.

Summary: The study assessed the potential of nanocomposite membranes (NCMs) made of sodium alginate and embedded with synthesized zeolitic imidazole framework-8 (ZIF-8) as fillers for separating gaseous mixtures generated by methane reforming. ZIF-8 crystals were synthesized through hydrothermal synthesis, with sizes ranging from 50 to 70 nm. NCMs with 15% filler loading (synthesized ZIF-8) outperformed neat polymer membranes in terms of H-2 permeability and selectivity, achieving a purity of up to 95%. However, NCMs did not perform better than neat polymer membranes in separating gas mixtures. The combination of ZIF-8 and sodium alginate as fillers is a new and worth investigating.

Summary: Polymeric rubber and organic semiconductor H2Pc-CNT composite-based shockproof deformable infrared radiation (IR) sensors were fabricated using a rubbing-in technique. The sensors showed decreased resistance and impedance when exposed to IR irradiation, and the temperature coefficients of resistance (TCR) were 1.2 and 1.1 for the surface-type and sandwich-type sensors, respectively. The high TCR value and novel composition of the H2Pc-CNT composite make these devices attractive for bolometric applications, and their easy fabrication and low-cost materials make them commercially viable.

Summary: The mixed micellization behavior of the antidepressant drug amitriptyline hydrochloride (AMT) and the nonionic surfactant triton X-165 (TX-165) was thoroughly investigated using various techniques. The interaction between AMT and TX-165 was found to be influenced by different solvents, with the interaction being more pronounced in NaCl solvent compared to aqueous and urea solutions. The formation of mixed micelles of AMT + TX-165 was found to be spontaneous and thermodynamically favorable. Molecular dynamics simulation confirmed the interactions between AMT and TX-165, providing a basis for the development of a drug delivery system.

Summary: The research focus is on modifying the physicochemical properties of ionic liquids using green co-solvents and characterizing them at the molecular level using spectroscopic techniques. The addition of polyethylene glycols (PEGs) to the IL 2-hydroxyethyl ammonium formate (HEF) alters its solvent properties in a positive way. The solvatochromic absorbance probes reveal interesting non-ideal behavior in the absorbance of Reichardt dye 33, which can be attributed to the high dipolarity/polarizability and hydrogen bond donor ability of the HEF + PEG mixtures.
