Comparison of Intergranular Corrosion Resistance and Hardness between Nitrogen and Carbon Martensites in Stainless Steels

steel research international, Volume 97, Issue 3, Page 1538-1546, March 2026.
By applying solution heat treatment after plasma nitriding, followed by requenching and tempering, researchers successfully obtained nitrogen‐rich martensite on AISI 409. This study compares the intergranular corrosion resistance and hardness of nitrogen‐rich martensite in AISI 409 with carbon‐rich martensite in AISI 420.

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 ...

Stemflow Dynamics in the Jamari National Forest (Brazilian Amazon): II. Solute Concentrations and Flux Dynamics

Biotropica, Volume 58, Issue 2, March 2026.
Trees can redirect large volumes of rainwater to the base of their stems. This stemflow not only redistributes water but also channels canopy‐derived solutes to the forest floor. Building on research showing canopy geometry and bark properties govern stemflow volumes, we examined how those same traits modulate the biogeochemical side of this flux. Over
