Four Decades of Research at the MADE Site and Beyond: Advancing the Understanding and Modeling of Solute Transport in Heterogeneous Media

open access: yesReviews of Geophysics, Volume 64, Issue 4, December 2026.
Abstract Spatial heterogeneity, manifested as strong variability in hydraulic conductivity (K) within geological formations, exerts a fundamental control on groundwater flow and solute transport. Because K can vary over multiple orders of magnitude in complex three‐dimensional patterns, predicting contaminant plume migration remains a long‐standing ...

Evaluation of plasma‐reaction‐driving capability in dielectric barrier discharge systems: Insights from CH4 splitting

open access: yesAIChE Journal, Volume 72, Issue 11, November 2026.
Abstract Dielectric barrier discharge (DBD) plasma systems are promising routes for CH4 splitting to COx‐free hydrogen, but their optimization has historically been hindered by the lack of a universal descriptor linking electrical input with chemical output.

Mixed‐Scale Powder Enables 3D Printing of Tungsten Alloy

open access: yesRare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT Laser powder bed fusion (LPBF) offers a promising route for manufacturing tungsten alloy components with complex geometries, whereas W–Ni–Fe alloys remain the most widely used tungsten alloys because of their excellent overall performance.

Hydrothermal Sealing at Turrialba, Poás, and Rincón de la Vieja Volcanoes (Costa Rica) Promotes Phreatic and Phreatomagmatic Eruptions

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract Hydrothermal sealing is a mechanism thought to be responsible for challenging‐to‐forecast phreatic and phreatomagmatic eruptions. To better understand this process, we present a study in which we assessed the textural, mineralogical, and physical properties (porosity, permeability, and tensile strength) of blocks of hydrothermal seal that were

Seasonal Shifts in Nitrogen Isotope Fractionation Regimes in the Leighton Cycle

open access: yesGeophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Nitrogen isotopes are used to trace nitrogen oxides (NOx = nitric oxide (NO) + nitrogen dioxide (NO2)) emissions and nitrate formation, but their interpretation depends on isotope redistribution during NO−NO2 cycling. A key uncertainty is whether this partitioning is controlled by equilibrium exchange or Leighton cycle.
