Summary: The ability of materials to conduct heat is crucial for various physical phenomena, from thermal management to thermoelectrics. Two-dimensional materials like InSe offer a versatile platform to tailor heat transfer due to their high surface-to-volume ratio and mechanical flexibility. Studies show that 2D InSe exhibits anomalous low thermal conductivity compared to traditional dielectrics, making it a promising candidate for future technologies that require efficient heat dissipation or thermoelectric energy conversion.

Summary: The TiZrNb metal-matrix composites reinforced by in-situ formed borides were produced using different amounts of TiB2. The composites exhibited varying microstructures and mechanical properties with the increase in boride content. Load transfer strengthening was found to be the main contributor to the overall strength of the composite. The biocompatibility evaluation suggested a decrease in the proliferation rate of mesenchymal stem cells with an increase in boride content.

Summary: Efficient organic photovoltaic devices fabricated from water-based colloidal dispersions with donor:acceptor composite nanoparticles achieving up to 9.98% power conversion efficiency (PCE) are reported. The high efficiency is attributed to morphology control by surface energy matching between the donor and the acceptor materials. The narrow gap between water-based inks and organic solvent-based inks is promising for the development of eco-friendly processing and fabrication of organic photovoltaics.

Summary: The glycosylation of egg white proteins with maltodextrin was studied. The glycosylated egg white proteins showed improved gel properties, such as increased hardness, water holding capacity, rheological parameters, and finer gel microstructures. The protein structures were unfolded due to glycosylation, as observed by changes in content of exposed sulfhydryl group and β-sheet, decreased crystallinity, thermal denaturation temperature, and enthalpy. The study provides insights into glycosylation mechanism and a convenient approach to improve the gel properties of egg white proteins.

Summary: The glycosylation of egg white proteins with maltodextrin was studied and the resulting glycosylated proteins showed improved gel properties such as increased hardness, water holding capacity, rheological parameters, and finer microstructures. The protein structures were unfolded due to extended glycosylation, as evidenced by increased exposed sulfhydryl groups and beta-sheet content, decreased crystallinity, thermal denaturation temperature, and enthalpy. The gel properties were correlated with the structural changes. Overall, this study provides insights into the mechanism of glycosylation and offers a convenient approach to enhance the gel properties of egg white proteins in the food industry.

Summary: Nanocomposites based on thermoplastic polyurethane and montmorillonite modified with oligourethaneammonium chloride were synthesized using solution exfoliation method. The filler content was found to significantly affect the thermodynamic interactions, physical and mechanical properties, structure and morphology of the nanocomposites. The study revealed that the free energy of mixing between the filler and matrix played a decisive role in determining the physical and mechanical properties of the nanocomposites. Modified montmorillonite with urethane-containing compounds could form strong hydrogen bonds with the polar polymer matrix and achieve exfoliation into platelets.

The dielectric constant of polyethylene oxide thin film is 10 times greater than that of bulk polyethylene oxide. There is consistency among dielectric constants, activation energies, and free volume fractions for both thin film and bulk samples. Polyethylene oxide thin film is observed to be more brittle than bulk polyethylene oxide.

Summary: Although molecular dynamics (MD) simulation is a powerful tool for investigating the atomic-scale structures of complex materials, its reliable and accurate application to multi-component glass systems faces challenges due to limited force fields (FFs) and the complexity of chemical environments. This study demonstrates the feasibility of efficient and accurate large-scale density functional theory (DFT) calculations for multi-component glass systems. The evaluation of classical FFs based on the results of large-scale DFT calculations reveals low accuracy for non-bridging oxygen atoms, and differences in Si-O-Si angle distribution and electronic structure for X = Mg.

Summary: In this study, vanadium oxide xerogel samples were successfully synthesized through a liquid phase reaction and the interaction of films with water. The samples were thoroughly analyzed using X-ray diffraction and Raman spectroscopy, revealing the existence of two distinct phases. It was also discovered that previous misinterpretations regarding the high-pressure polymorph structure were due to the formation of a high-temperature phase. These findings highlight the potential for further refining and expanding the current structural models of vanadium oxide xerogel in future research efforts.
