Thickness Calculation of Pigment Layers and Gold Leaves Using XRF and MA‐XRF Data

open access: yesX-Ray Spectrometry, Volume 55, Issue 2, Page 335-348, March/April 2026.
ABSTRACT In this work, XRF and MA‐XRF data were used to estimate the thickness of Chromium Oxide (Cr₂O₃) pigment and gold leaf applied over Lead White (2PbCO3.Pb(OH)2). The thickness determination was based on the differential attenuation of the Pb‐Lα and Pb‐Lβ characteristic X‐rays, which allows correlating the overlying material layer with the Pb(Lα ...

Projections of Atmospheric Moisture Transport Over South America in a Changing Climate

open access: yesInternational Journal of Climatology, Volume 46, Issue 2, February 2026.
End‐of‐century (2071–2100) climate projections show significant contrasts in atmospheric moisture over South America, with increased divergence over Northern Chile and Eastern Brazil and stronger convergence over the La Plata and Magdalena basins. Moisture convergence raises risks of extreme rainfall and floods, while divergence intensifies droughts ...
