Systematic Approach for Carbonate and Volcanic Facies Classification Based on Textural and Structural Variations Observed in Brazilian Pre‐Salt Acoustic Image Logs

open access: yesJournal of Petroleum Geology, Volume 49, Issue 3, Page 869-906, July 2026.
ABSTRACT Facies characterization in carbonate reservoirs remains challenging due to their pronounced textural and structural heterogeneity. Variations in grain packing, cementation, and diagenetic overprints produce contrasting acoustic responses in borehole image logs, often limiting the reproducibility of facies interpretation.

Guidelines for Comparing Circular Dichroism Spectroscopy and Molecular Dynamics Simulations for Biomolecules

open access: yesChemPhysChem, Volume 27, Issue 12, 26 June 2026.
A direct comparison is made between circular dichroism (CD) spectroscopy and molecular dynamics (MD) simulations for studying peptide partitioning through biological membranes. The assumptions and limitations of each method is discussed, and case studies are provided for their use.

Proton‐Radiation Hardening of High‐Speed Ge/Si Integrated Photodetectors for Space Applications

open access: yesNanophotonics, Volume 15, Issue 12, 25 June 2026.
Hydrogen loading is demonstrated as a radiation‐hardening strategy for high‐speed Ge/Si integrated photodetectors under broadband proton irradiation. By suppressing irradiation‐induced leakage‐current growth and mitigating bandwidth degradation, hydrogen‐loaded devices maintain high‐speed operation and improved stability, providing a practical route ...

The Synthetic Edge: Unlocking Superior Performance in High‐Nickel Li‐Rich Layered Oxide Cathodes for Advanced Lithium‐Ion Batteries

open access: yesChemElectroChem, Volume 13, Issue 12, 17 June 2026.
Sol‐gel synthesis is shown to produce Ni‐rich Li‐rich layered oxide cathodes with superior phase purity, crystallinity and reduced surface Li2CO3, yielding smaller homogeneous particles. These improvements translate into significantly enhanced electrochemical performance (~200 mAh g−1; 99.5% Coulombic efficiency; 80.6% capacity retention after 500 ...

Revealing the Formation of the <20 MeV Inner Proton Radiation Belt at L ∼ 2 During the 10–11 May 2024 Superstorm

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract A new proton radiation belt was identified during the geomagnetic superstorm of 10–11 May 2024. To investigate its origin, we use an MHD‐test particle simulation to model solar energetic proton (SEP) trapping and the evolution of the initial trapped proton population during the storm.
