Oxygen Fugacity Buffers and an Interactive Calculator

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract Oxygen fugacity buffers are equilibrium phase assemblages that constrain the chemical potential of oxygen. They may be coexisting minerals or fluids, or their metastable extrapolations. Oxygen fugacity values vary as a function of pressure and temperature, such that raw numbers often have little interpretive value.

Attention and Geological Knowledge Guided Spectral‐Spatial Networks for Geochemical Anomalies Recognition

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Achieving both accuracy and interpretability in deep learning models for geochemical anomaly recognition constitutes a significant challenge. To overcome this challenge, this study developed a novel interpretable dual‐branch network combining a spectral attention bidirectional RNN (BiRNN) branch and a spatial attention CNN branch guided with ...

Shannon sampling based approach for the structural solution of nano‐objects by laboratory and synchrotron SAXS data

open access: yesJournal of Applied Crystallography, Volume 59, Issue 4, Page 1170-1183, August 2026.
We present a model‐independent approach based on the Shannon sampling theorem to retrieve key structural parameters of proteins and core–shell micelles directly from small‐angle X‐ray scattering (SAXS) profiles. By bypassing the pair distribution function, the method overcomes q‐truncation artifacts and provides reliable mass, size and aggregation ...

Temperature evolution of the high‐harmonic magnetic modulations in DyFeO3

open access: yesJournal of Applied Crystallography, Volume 59, Issue 4, Page 1332-1337, August 2026.
The temperature evolution of the high‐harmonic incommensurate magnetic ordering of Dy3+ in DyFeO3 orthoferrite is compared with the literature results on the soliton lattice of TbFeO3 observed in an external magnetic field.We report on the temperature evolution of magnetic satellites associated with the incommensurate magnetic ordering of Dy3+ ions in ...
