Multiple thermophysical effects of aeolian sand cover on permafrost under climate warming and wetting

open access: yesGeoderma
Permafrost degradation on the Tibetan Plateau (TP) poses serious risks to the environment and infrastructure. Permafrost changes are controlled by both climate changes and local factors, including climate warming, wetting, and aeolian desertification ...

Effects of Pyrolysis Control Parameters on the Structural Properties of Biomass‐Derived Activated Carbon Materials and Their Energy Applications

open access: yesThe Chemical Record, Volume 26, Issue 3, March 2026.
Tubular pyrolysis synthesis is a widespread method to produce activated carbons (ACs). This review focuses on the different controlling parameters of the tubular pyrolysis synthesis method and their influence on the performance of synthesized ACs, thereby considering both experimental aspects and the use of plant‐based biomasses (PBBs) as feedstock ...

Quantifying Gas and Thermal Energy Emissions in an Active Geothermal Area: Insights From Le Biancane (Larderello Field, Italy)

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The Larderello‐Travale area in the northern Apennines of Italy hosts the world's oldest exploited geothermal field. Its success lies primarily in the presence of an extraordinary geothermal resource housed in a large vapor‐dominated fractured reservoir that produces superheated steam.

Behavior of Coastal Amagmatic Geothermal Systems: Thermal–Hydraulic Modeling Insights From La Jolla Beach, Baja California, Mexico

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Amagmatic geothermal systems in coastal locations are promising energy resources, yet the processes that localize and sustain their hot‐spring discharge remain unclear. We investigate La Jolla Beach (NW Baja California, Mexico)—one of the hottest known examples worldwide (∼100°C)—using large‐scale 3D coupled thermal–hydraulic simulations.

Rover‐Induced Mineral Transformations: Extent of the Effect for the Mars Science Laboratory and Opportunities for Future Landed Mission

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract X‐ray amorphous sulfate hydrates are a substantial component (up to 23 wt%) of the sedimentary rocks and sands analyzed to date by the Mars Science Laboratory Curiosity rover at Gale crater. Recently, the CheMin X‐ray diffractometer observed the amorphization of the crystalline sulfate starkeyite (MgSO4 · 4H2O) upon exposure to the dry and ...

Lithospheric Mantle Heterogeneity Drives Delayed Magmatism and Wide Continent‐Ocean Transitions in Rifted Margins

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract The formation of wide, magma‐starved continent–ocean transition (COT) zones remains incompletely understood. We use 2‐D thermo‐mechanical numerical experiments, coupling hydrous mantle melting with parameterized crustal accretion, to explore controls on magmatic lag: the delay between continental crustal break‐up and steady oceanic crustal ...

Global Desert Variations During 1985–2024 Associated With Effective Water Availability

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Under accelerating climate change, variations in global desert area remain uncertain, with estimates differing by more than a factor of two. Here, we present the first 40‐year global mapping of desert area changes at 30 m resolution using Landsat imagery, achieving a classification accuracy of 92%.

Synergistic effects of magnetic fields and Y-obstacles on a nanofluid-based split lid-driven thermal system

open access: yesInternational Journal of Thermofluids
This study investigates the complex hydrothermal behavior in a novel split-driven square cavity filled with CuO-water nanofluid and featuring a Y-shaped obstacle. The research explores the interplay among mixed convection, magnetohydrodynamics (MHD), and
