    Influence of vanadium oxide on the structural, optical, mechanical and dielectric properties of cadmium borate glasses by A. Kh. Helmy, Takwa E. Ellakwa, Gehan T. El-BassyounI, M. A. Azooz, M. A. Ouis, Mohammed A. Taha

    Published 2025-07-01
    “…The successive addition of V2O5 up to 2 mol% at the expense of CdO in the glass network led to an increase in density from 4.27 to 4.69 g/cm3 for the prepared glasses while adding more V2O5 led to a decrease in density. The molar volume showed the same trend that occurred in the density, but in an opposite direction, as it decreased by increasing V2O5 content till the 2 mol% samples, then increased. …”

    Comparative Analysis of Bioactive Compounds and Flavor Characteristics in Red Fermentation of Waxy and Non-Waxy Millet Varieties by Zehui Yang, Jie Liu, Xiaopeng Li, Changyu Zhang, Pengliang Li, Yawei Zhu, Jingke Liu, Bin Liu

    Published 2025-07-01
    “…(1) Background: This study investigated changes in bioactive components and volatile compounds (VCs) during the production of red millet by comparing two varieties: Miao Xiang glutinous millet (waxy) and Jigu-42 (non-waxy). The samples were solid-state-fermented with “<i>Red Ferment</i>” and evaluated for bioactive components. (2) Methods: Multiple analytical methods—including principal component analysis (PCA), partial least squares-discriminant analysis (PLS-DA) and orthogonal PLS-DA (OPLS-DA), cluster analysis, and correlation analysis—were employed to systematically compare bioactive components and VCs. (3) Results: Significant varietal differences were observed: (1) Miao Xiang glutinous millet showed higher monacolin K (MK) and fatty acid contents; (2) Jigu-42 contained significantly more polyphenols; (3) linoleic acid dominated the fatty acid profiles of two varieties; and (4) a total of twenty-seven VCs were identified, including six alcohols, four aldehydes, seven ketones (corrected from duplicated count), two aromatic hydrocarbons, three heterocycles, one acid, three furans, and one ether. (4) Conclusions: The two varieties exhibited significant differences in MK, pigment profiles, fatty acid composition, polyphenol content, and volatile-compound profiles. …”
