Summary: The melt-quenching route was utilized to produce phosphate glasses in the system of 20Na2O-(50-x) Na2WO4-30P2O5: xTiO2 with 0 <= x <= 25 mol%. Various characterization techniques were employed to investigate the influence of TiO2 on the physical-optical parameters of the synthesized glasses. It was found that as the TiO2 content increased, the density values decreased, while the optical band gap (Eg) decreased and Urbach energy (Delta E) increased. The placement of TiO2 in glasses was related to the creation of non-bridging oxygens. Moreover, an increase in TiO2 mol percent resulted in a decrease in optical basicity, electronic polarizability, optical electronegativity, and the electronic polarizability, as well as an increase in refractive index, dielectric constant, and optical dielectric constant.

Summary: Supercontinuum generation from alkali antimony zinc borate glasses was studied using a femtosecond laser. The optical bandgap values were determined for all glass samples. Enhanced SC generation was observed in sodium-doped glass, despite its lowest bandgap among the samples. The physical and structural parameters of the glasses were analyzed and discussed, along with the observed shift in binding energies of metal cations and oxygen anions using XPS analysis. These observations provide insight into the anomaly in the enhanced SC generation from the low bandgap sodium-doped glass.

Summary: Three systems of alkali borate glasses containing either 0.15% CuO or ZnO were prepared and their optical, physical, and radiation shielding properties were analyzed. The glasses showed good stability in optical properties before and after gamma irradiation. Their efficiency as radiation shielding materials was discussed based on calculations and simulations, showing high efficiency depending on the molecular weight of transition metal ions and the effective atomic number of the glasses.

Summary: The conceptual design of high-entropy materials is expanded to oxide glasses, and a series of LaO3/2-TiO2-NbO5/2-WO3-MOx (M = Mg/Al/Si, and x = 1, 3/2, 2) glasses are successfully synthesized. The transparent glasses possess excellent thermal stability with a glass transition temperature above 73°C. The large temperature gap ΔT, exceeding 60°C and reaching a maximum of 107°C for M = Si, is attributed to the nature of SiO2 as a network former and the complex atomic interactions resulting from high entropy. The M = Al glass exhibits the highest refractive index (n(d) = 2.33) and visible transmittance (74%), maintaining its performance after electron beam irradiation in the IR region, indicating excellent irradiation resistance.

Summary: This paper proposes a technique using directly coupled stacked patches to increase impedance bandwidth and reduce cross-polarization. By employing metallic shorting posts between the metallic patches, the stacked configurations achieve a bandwidth of 25.8% and a gain of 8.8 dBi with low cross-polarization levels. A symmetrically direct-coupled stacked design further suppresses cross-polar components, resulting in a bandwidth of 26.1% and a gain of 9.3 dBi.

Summary: The aim of this study was to determine the optimum condition for preparing chitooligosaccharide-catechin conjugate (COS-CAT) liposomes using different stabilising agents. COS-CAT liposomes were prepared using soy phosphatidylcholine (SPC) and either glycerol or cholesterol, and their encapsulation efficiency, loading capacity, physicochemical characteristics, FTIR spectra, thermal stability, and structure were assessed. The results showed that COS-CAT loaded liposome stabilised by cholesterol (COS-CAT-CHO) exhibited higher stability, with the highest encapsulation efficiency and loading capacity, and the lowest zeta potential, polydispersity index, and releasing efficiency.

Summary: Enrichment of n-3 polyunsaturated fatty acids (PUFA) in skipjack tuna eyeballs oil (STEO) was investigated using lipases from different yeast strains. Among all lipases tested, Candida rugosa extracellular lipase (Cr-ECL) showed promising enrichment of EPA and DHA in STEO. RSM was used to optimize reaction conditions and resulted in a significant increase in DHA and EPA concentration in STEO. The established hydrolysis protocol successfully converted fish oil from tuna waste to valuable fish oil enriched with n-3 fatty acids.

HyS also improved the water-holding capacity and increased hardness, springiness, gumminess, and chewiness of the gel. The addition of HyS enhanced the connections between surimi proteins and improved the gel network.

Summary: The gelling behaviors of partially purified myofibrillar proteins (PPMP) extracted from Indian mackerel (IM) and threadfin bream (TB) were compared at different heating temperatures. The results demonstrated that IM-MP exhibited lower turbidity, surface hydrophobicity, and disulfide bond content compared to TB-MP. The amino acid profile showed no significant difference between the two species, except for lysine and glutamine. Structural analysis confirmed these differences, and the transmission analysis revealed lower aggregation and crosslinking ability of IM-MP. Therefore, the gelling behavior of IM-MP was poorer compared to TB-MP.

Summary: The inhibitory effects of chitooligosaccharide (CHOS) conjugates, including CHOS-catechin (CHOS-CAT), CHOS-epigallocatechin gallate (CHOS-EGCG), and CHOS-gallic acid (CHOS-GAL), on Pacific white shrimp cephalothorax polyphenoloxidase (PPO) were studied. CHOS-CAT showed the strongest inhibitory activity against PPO and exhibited mixed-type inhibition. Molecular docking analysis revealed that CHOS-CAT interacts with various amino acid residues near the active site of PPO. Therefore, CHOS-CAT could serve as an anti-melanosis agent to prevent discoloration in crustaceans.

Summary: The effects of epigallocatechin gallate (EGCG) at 200 or 400 ppm on the quality changes of cooked Harpiosquillid mantis shrimp (Harpiosquilla raphidea) (CHMS) meat subjected to varying freeze-thaw cycles (F-T-C; 0, 1, 3, and 5) were studied. With increasing F-T-C, the CHMS meat deteriorated to a higher extent, indicated by increased exudate loss, tougher texture, and higher microbial counts. The addition of EGCG could dose-dependently retard these changes, as well as prevent microbial growth and lipid oxidation. The alterations in disulfide bond content and surface hydrophobicity of CHMS added with EGCG were more pronounced with higher EGCG concentration.

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.
