• Non-invasive optical spectroscopy and TEM study of the crystallization process of a new woven alumina fiber · 2027

  Résumé de la publication : The low wavenumber range (Rayleigh wing and Boson peak) and fluorescence, arising from chromium as a natural impurity in alumina, were used to monitor the crystallization process of alumina in small-diameter fibers, intended for use in CMCs, and derived from an amorphous…

• How Adsorption Geometry Dictates Chiroptical Properties: A Computational Study of L-Cysteine on Au(111) Cluster Models · 2026

  Résumé de la publication : Understanding chirality transfer in metal nanoclusters is crucial for developing advanced materials with tailored optical properties. This study investigates the chiroptical properties of gold clusters functionalized with L-cysteine using time-dependent density functional theory (TD-DFT). By exploring different ligand adsorption configurations, molecular orientations,…

• Exploring the Vibrational Raman Modes of P-O-P Bonds in Oligomeric Sodium Metaphosphates: A Comprehensive DFT Study · 2026

  Résumé de la publication : This work presents an in-depth density functional theory (DFT) study aimed at elucidating the Raman vibrational patterns of P-O-P bonds in oligomeric structures of sodium metaphosphate (NaPO₃)n structures. To investigate their vibrational behavior, DFT methods were employed on three oligomeric crystal structures:…

• Unveiling the Early Species of Silica-Based Materials: Raman Characterization of Silica Oligomers · 2026

  Résumé de la publication : Silica oligomers formed in solutions are difficult to characterize due to their size and chemical dynamics. Raman spectroscopy is well suited to track such structures, provided that a clear, unambiguous identification of the compounds is established. We report a comprehensive theoretical and…

• Non-Invasive Identification of Blue-And-White Porcelain: Comparison of Vietnamese, Yunnan and Jingdezhen Wares Using Reasoned Visualization and PCA · 2026

  Résumé de la publication : The XRF, Raman, and fluorescence signatures of approximately fifteen blue-and-white and white porcelain sherds are compared. The assemblage comprises fourteenth-to sixteenthcentury porcelain sherds, including Yuan and Ming wares from the Jingdezhen kiln sites, fifteenth-to sixteenth-century wares from the Yuxi and Jianshui kiln…
