    Published 2025-05-01
    “…The change in the chemical composition of the colors was monitored before and after aging by FTIR, EDS, which showed changes in terms of the appearance of the iron element (Fe) and an increase in its concentration after aging, which confirms that the color was affected by iron rust resulting from the rust of the iron nails fixed to the fabric layer stained with rust that migrates through the layers that are damaged due to the migration of Fe2+ ions to the surface of the colors in the presence of alkaline metal cations in the chemical composition of the three earth colors. …”

    Systematic study of drug distribution profiles of different nanocarriers in the skin layers: a more accurate and targeted delivery by Manuela Gonçalves, Kelly Cristine Zatta, Adriana Raffin Pohlmann, Silvia Stanisçuaski Guterres

    Published 2024-12-01
    “…In vitro release experiments combined with in vitro percutaneous penetration/permeation data demonstrated that the localization of the substance in the nanoparticles (determined by Log D) is crucial for understanding their diffusion behavior. The results demonstrated that substances of moderate lipophilicity, such as MEL, are affected by the molar mass of the polymer since the use of 80,000 g mol-1 PCL in the particle composition (LNC80MEL) guaranteed a greater encapsulation efficiency (EE%) (55%). …”

    Using Carbon Isotope Equilibrium to Screen Pedogenic Carbonate Oxygen Isotopes: Implications for Paleoaltimetry and Paleotectonic Studies by Nathan D. Sheldon

    Published 2018-01-01
    “…Based upon 51 modern soils from monsoonal, continental, and Mediterranean moisture regimes, Δ13C = +15.6 ± 1.1‰ (1σ), which closely matches theoretical predictions for carbonates formed at carbon isotope equilibrium through Fickian diffusion. Examples from both disequilibrium and equilibrium cases in the geologic record are examined, and it is shown that previous δ18Ocarb records used to infer Cenozoic uplift in southwestern Montana do not provide any constraint on paleoelevation because >90% of the pedogenic carbonate isotopic compositions are out of equilibrium. …”
