  1. Direct optical observation of solid electrolyte interphase formation ...

    This work establishes a direct mechanistic link between formation conditions and interphase uniformity, providing guidance for efficient and safe battery manufacturing.

  2. A billion-year shift in the formation of Earth’s largest ore ... - PNAS

    New geochronology conclusively links all major preserved hematite deposits to a far younger (1.4 to 1.1 Ga) formation period, correlated with the amalgamation of Australia following breakup of the …

  3. Keys to the global treeline formation: Thermal limit for its ... - PNAS

    Different physiological limits among tree taxa could influence the formation of treelines and their response to environmental changes. However, taxon-specific variability and geographical patterns …

  4. Multiple formation pathways for amino acids in the early Solar System ...

    While we cannot definitively identify the formation pathway for glycine in the Bennu sample, the isotopic data presented here provide insight into which mechanisms were more likely than others.

  5. Reversibility and β-sheet formation are decoupled in tau ... - PNAS

    Mar 13, 2026 · Early events in tau aggregation are increasingly linked to the formation of biomolecular condensates, which lower the energetic barriers to pathological aggregation by acting as …

  6. A conserved ethylene-triggered cell death mechanism may underlie

    Mar 25, 2026 · This study not only fills a major knowledge gap in the adaptive mechanisms of hollow stem formation but also opens broad avenues for agricultural and ecological applications, offering …

  7. Phase transfer–driven formation of solid metal–organic ... - PNAS

    Specifically, optical microscopy (OM) and UV–vis spectra/fluorescence spectra were used to examine the formation of the assemblies and their optical properties (SI Appendix, Figs. S7–S25).

  8. Spontaneous dark formation of OH radicals at the interface of ... - PNAS

    Extrapolation of our observed OH formation rates to atmospheric conditions indicates that this source could be a major but previously unrecognized contributor to the atmospheric aqueous OH formation, …

  9. Persistent sulfate formation from London Fog to Chinese haze

    We suggest that effective haze mitigation is achievable by intervening in the sulfate formation process with NH 3 and NO 2 emission control measures. Hence, our results explain the outstanding sulfur …

  10. Biologically recycled continental iron is a major component in ... - PNAS

    Jun 24, 2015 · A Heimann, et al., Fe, C, and O isotope compositions of banded iron formation carbonates demonstrate a major role for dissimilatory iron reduction in ∼2.5 Ga marine environments.
