Hyperspectral Fingerprinting of Dune Sediments Across the Arabian Peninsula: Insights Into Sediment Provenance and Transport Pathways From NASA's EMIT Data

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The Arabian Peninsula encompasses one of the world's most extensive aeolian systems, yet the provenance and transport history of its dune sediments are not well understood. Using hyperspectral data from NASA's Earth Surface Mineral Dust Source Investigation (EMIT), we mapped mineral compositions and abundance patterns across dune fields and ...

Low Abundances of Ultramafic Components in the Chang'e‐6 Landing Site Basalt and Ejecta Material

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The South Pole‐Aitken (SPA) Basin, the Moon's largest impact structure, holds key insights into lunar evolution, prompting the Chang'e‐6 mission to return first samples for ground‐truth verification. Analysis of over 6,000 grains from the Chang'e‐6 soil returned from the SPA Basin reveals a composition dominated by clinopyroxene (26.5–32.9 vol.

Thermal and Photocatalytic Conversion of CO2 to Ethanol: Advances in Catalyst Design, Challenges, and Opportunities

open access: yesChemSusChem, Volume 19, Issue 12, 26 June 2026.
This review examines thermo‐ and photocatalytic routes for converting CO2 to ethanol and analyzes how metal alloying, promoters, supports, surface structure, and semiconductor design govern catalyst activity, selectivity, and stability. It integrates mechanistic insights from experimental and theoretical studies and identifies the main challenges and ...

Dynamic Oxygen Species Evolution Boosts Acidic Water Oxidation on W‐Doped RuO2

open access: yesChemElectroChem, Volume 13, Issue 12, 17 June 2026.
Dynamic oxygen species evolution is triggered in tungsten‐doped RuO2 through regulated lattice oxygen diffusion kinetics during acidic oxygen evolution. An optimized oxygen diffusion coefficient balances lattice oxygen participation and vacancy replenishment, driving the transformation from defective low‐coordination sites into a stable six‐coordinated

ReOx/TiO2: An Efficient Catalyst for the Production of Butanediols From Erythritol in Water

open access: yesChemSusChem, Volume 19, Issue 11, 15 June 2026.
A nonnoble metal heterogeneous catalyst, ReOx/TiO2, has been used for the successful valorization of erythritol into biosourced butanediols. The TiO2 support influences the formation of the various supported Re species, whose repartition has an impact on the catalytic phenomena.

Dopant Activation in Ta‐Doped SnO2 via Postdeposition Annealing for Transparent Electrodes

open access: yesphysica status solidi (a), Volume 223, Issue 11, 10 June 2026.
This study explores the thermal activation of tantalum dopants in room‐temperature deposited tin oxide films. By optimizing deposition pressure, dopant concentration, and annealing temperature, the dominant conduction mechanism shifts from oxygen vacancies to activated dopants. The resulting transparent electrodes achieve high optical transmittance and

Copper Nanocrystallization in Anodic Oxide Films of Ti–Cu‐Based Bulk Metallic Glass and Its Effect on the Corrosion Resistance and Cytocompatibility

open access: yesAdvanced Engineering Materials, Volume 28, Issue 11, 3 June 2026.
Viktoriia Shtefan, Thorgund Nemec, Ute Hempel, Annett Gebert and coworkers demonstrate that anodic treatment of Ti–Cu‐based metallic glass in a nontoxic pyrophosphate electrolyte forms a protective bilayered Ti/Zr‐oxide film enriched with Cu nanocrystals.

Enhanced Li‐Ion Battery Performance with Hybrid MXene/GnR Electrodes: Heterojunctions and Engineered Architectures Supported by DFT Mechanistic Studies for Improved Rate Performance, Stability & Capacity

open access: yesAdvanced Functional Materials, Volume 36, Issue 46, 8 June 2026.
Lithium‐ion batteries (LIBs) remain central to energy storage but suffer from slow ion transport and degradation. Here, we present a binder‐free Ti3C2Tx MXene/GnR hybrid electrode with a porous 3D architecture formed via freeze casting. The structure enhances conductivity, ion transport, and stability, delivering 401 mAh/g, ∼97% efficiency, and 92 ...

Dual‐Function Interface Engineering for δ‐Phase‐Free Crystallization Toward Efficient and Stable FAPbI3 Perovskite Solar Cells

open access: yesAdvanced Functional Materials, Volume 36, Issue 49, 18 June 2026.
This work presents a dual‐function interface engineering strategy using PEACl to suppress the formation of the non‐perovskite δ‐FAPbI3 phase at the critical SnO2 buried interface. This approach enables the direct crystallization of the photoactive α‐phase, yielding highly efficient and stable rigid (25.6%) and flexible perovskite solar cells with ...
