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

X-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 ...

The Effect of Graphene on the Fatigue Response and Failure Mechanism of Composite Materials: A Review

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 3, Page 933-962, March 2026.
ABSTRACT This review investigates the influence of graphene on the fatigue performance of polymer‐based composites, focusing on both unreinforced matrices and fiber‐reinforced composite laminates. Graphene materials, including nanoplatelets, graphene oxide, and hybrid nanostructures, offer exceptional mechanical, electrical, and barrier properties that

Veterinary and Comparative Oncology, Volume 24, Issue 1, Page 105-120, March 2026.
ABSTRACT Melanocytic tumours (MT) occur in both humans and companion animals, presenting an opportunity for comparative oncology research. Thus, this study provides a comprehensive epidemiological analysis comparing MT in Portuguese dogs, cats and humans. Data were obtained from the Portuguese National Cancer Registry (RON) (2011–2021) and Vet‐OncoNet (
