Integration of Micro‐CT and XRF Mapping for Multimodal 3D Analysis of Polychrome Wooden Artifacts

X-Ray Spectrometry, EarlyView.
ABSTRACT Over the past 5 years, computer applications have become crucial to archeological research. Since the 1990s, the focus has transitioned from data management tools to the development of virtual models. Recently, digital documentation of cultural heritage has gained considerable focus, with 3D modeling of objects.

Tuning the Surface State and Zeta Potential of Aged CuO Nanoparticles by Additive‐Free Surface Treatments as Guided by XPS

Advanced Materials, Volume 38, Issue 5, 22 January 2026.
Aging of CuO nanoparticles (NP) involves a surface reconstruction induced by hydroxylation and concurrent organic‐O adsorption, which introduces O defects in the NP subsurface region. The defective surface results in a diffuse surface space region, as reflected by a low ζ‐potential of the aged NPs in ethanol solvent.
