Homogenization of Solute Transport in Double Porosity Materials
Mathematical Methods in the Applied Sciences, Volume 48, Issue 11, Page 11419-11432, 30 July 2025.ABSTRACT We propose a novel model for the transport of solute in a vascularized poroelastic material. Our structure comprises a poroelastic matrix with an embedded connected fluid compartment, and we consider a solute transported between the two subdomains.

Commentary: Intense Upper Mantle Hydration of the Pacific Plate Beneath the Southern Mariana Trench
Geophysical Research Letters, Volume 52, Issue 13, 16 July 2025.Abstract To date, estimates of mantle serpentinization in trench‐outer rise regions have largely relied on Vp models from controlled‐source seismic experiments. A recent study by He et al. (2025; https://doi.org/10.1029/2024GL113792) presented both Vp and Vs models along a seismic profile crossing the southern Mariana Trench near the Challenger Deep ...

Ambient Air Deposition Allows Reaching Record Light Use Efficiency in FAPbI3 Perovskite Solar Cells
Advanced Science, Volume 12, Issue 25, July 3, 2025.Ambient air deposition of Formamidinium Lead Iodide (FAPbI3) perovskite enables an increase in average visible transmittance (AVT) value by up to 40%, while also enhance the optoelectronic quality of the film, showing fewer defects and a superior morphology. As a result, semi‐transparent devices achieve a record light use efficiency (LUE) value of 4.2%,

Stability to double timoshenko thermoelastic beam
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 105, Issue 7, July 2025.Abstract In this work, we study, from both analytical and numerical points of view, a thermoelastic problem involving two elastic beams, which are modeled by using the classical Timoshenko model. The resulting problem is written in terms of the transverse displacements, the angles of rotation, and the temperatures of the beams.
