Interference of TiO2 in Fricke Dosimetry: Adsorption Mechanisms and Dose Measurement Challenges under Gamma Irradiation

open access: yesChemistryOpen, Volume 15, Issue 4, April 2026.
The presence of TiO2 in Fricke dosimetric systems introduces complex interferences under gamma irradiation. Adsorption of Fe2+/Fe3+ ions, coupled with radiolytic and surface‐mediated processes, alters redox equilibria and apparent absorbed dose values, highlighting critical challenges in chemical dosimetry applied to heterogeneous radiolytic ...

Experimental and Numerical Investigation of the Characteristic Length Governing Soil Evaporation in Layered Sands

open access: yesWater Resources Research, Volume 62, Issue 4, April 2026.
Abstract In arid and semi‐arid regions, ecosystems exist with shallow water tables, where evaporation is a key component of the water balance. However, systematically addressing soil evaporation remains challenging due to differing interpretations of the mechanisms that control it.

Growth and reworking of freshwater microbially‐mediated carbonates in wind‐stressed lake margins (Lago Sarmiento, Southern Patagonia)

open access: yesSedimentology, Volume 73, Issue 3, Page 706-741, April 2026.
ABSTRACT Understanding the biotic and abiotic influences on the deposition and diagenesis of recent microbial carbonates is crucial for addressing the environmental and ecological significance of ancient organosedimentary structures. This study investigates these factors and their expression in the microstructure of Holocene tufa thrombolites from a ...

Homogeneous Observer‐Based Affine Formation Tracking

open access: yesInternational Journal of Robust and Nonlinear Control, Volume 36, Issue 5, Page 2692-2704, 25 March 2026.
ABSTRACT This article addresses the control of mobile agents, termed followers, to track a time‐varying affine formation specified by a set of leaders. We present a distributed hierarchical method composed of a homogeneous high‐order sliding mode observer and a tracking controller. The observer estimates the followers' target trajectories from neighbor
