A Radiocarbon‐Based Framework to Assess Soil Organic Carbon Persistence and Vulnerability Across Land‐Use Types

open access: yesGlobal Change Biology, Volume 32, Issue 3, March 2026.
Soil organic carbon (SOC) persists over timescales from years to millennia but remains vulnerable to disturbance depending on stabilization mechanisms and environmental constraints. This study assesses SOC persistence and vulnerability across five land‐use types by combining radiocarbon‐derived system age and transit time with indicators of biological ...

Heat Transfer in Nuclear Waste Glasses: Measurements and Modeling of Thermal Radiation Properties

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 3, March 2026.
ABSTRACT We measured and modeled near‐infrared extinction of nuclear waste glasses from 300°C to 1150°C to enable predictive radiation heat transfer and thermal conductivity estimates. A composition‐ and redox‐informed model resolved contributions from key chromophores (Fe+2‐O‐Fe+3, V+4, free and bonded ≡Si‐OH groups) and, when present, spinel ...
