Calcination‐Induced Pore Evolution in TiO2 Supports Governing Ni Accessibility for Dry Methane Reforming

ChemistryOpen, Volume 15, Issue 5, May 2026.
Ni/TiO2 catalysts with tunable pore structures were developed to study how support calcination temperature affects Ni accessibility and dry reforming of methane (DRM, CH4 + CO2 → syngas). Low‐temperature TiO2 forms mesopores that trap Ni, while high‐temperature calcination generates macroporous/plate‐like structures that expose Ni and enhance catalytic

A Needle‐Like MOFzyme with High Aspect Ratio and Extended pH/Temperature Working Ranges for Total Antioxidant Capacity Determination and Oxidant‐/Light‐Free Dye Degradation

ChemistryOpen, Volume 15, Issue 5, May 2026.
A needle‐like MOFzyme with high aspect ratio and extended pH/temperature working ranges was developed for quantification of total antioxidant capacity and oxidant‐/light‐free dye degradation. A needle‐like MOFzyme with high aspect ratio and extended pH/temperature working ranges was developed for quantification of total antioxidant capacity (TAC) and ...

Toward Efficient and Reliable Chemical Upgrading Using Solid Oxide Electrochemical Reactors, Mechanisms, Challenges, and Design Principles

Small, Volume 22, Issue 27, 14 May 2026.
Solid oxide electrochemical reactors (SOERs) offer a compelling pathway for coupling renewable electricity with chemical manufacturing, but their real application is still limited by low efficiency and instability. This review systematically summarizes SOER reaction mechanisms, performance‐limiting factors, and recent progress toward high‐efficiency ...

Mapping Subsea Permafrost Distribution in the Canadian Beaufort Sea With Marine Seismic and Deep Learning

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Subsea permafrost is widespread across the polar continental shelf, and mapping its distribution is crucial for assessing the possible impact of its degradation in response to global warming. While seismic techniques have been useful in determining the lateral extent of subsea permafrost in the Canadian Beaufort Sea, are limited when it comes ...

Thermodynamic Constraints on H2 Production and Habitability From Mg‐Rich Serpentinites as Mars Analogs

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Serpentinization produces hydrogen and methane through abiotic water‐rock interactions, potentially supporting chemotrophic life in planetary subsurface environments. Serpentine deposits in the Martian Noachian landscapes of Nili Fossae and the Southern Highlands have been considered as potential paleo‐habitable zones. However, the geochemical

Spatial and Temporal Variability of Eastern Pacific Radiocarbon and Carbon Chemistry From the Ice Age to Today

Paleoceanography and Paleoclimatology, Volume 41, Issue 5, May 2026.
Abstract Proxy records of seawater radiocarbon (14C/C) provide strong constraints on how changes in ocean ventilation contributed to the increase in atmospheric CO2 during the termination of the last ice age (≈18,000‐to‐12,000 years ago). One outstanding problem, however, is the existence of anomalously low deglacial benthic foraminiferal 14C/C in the ...

Gas Permeability of Frozen Sediments: Implications for Modeling Gas and Water Transport in Permafrost

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract We measure the gas permeability of two permafrost sediments at a range of ice saturations and use van Genuchten‐Mualem equations to model the relative gas (krg) and water (krw) permeabilities of frozen sediments. We show that our frozen sediment krg data and model display the same functional form as frozen and unfrozen sediment krg data from ...

Consolidated‐Undrained Shear Behavior of Diatomaceous Mudstones: Implications for Submarine Landslides

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Submarine landslides occur globally and have the potential to damage seafloor infrastructure and trigger tsunamis. Recently, diatomaceous weak layers have been hypothesized to play a role in triggering submarine landslides on passive continental margins by generating overpressure.
