    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. …”

    Effect of Cooling Rate on the Characteristics of Eutectic Carbides in M2Al High-Speed Steel by Jianghua Xiang, Hui Yang, Changling Zhuang

    Published 2025-05-01
    “…Finally, combining thermodynamic calculations with kinetic analysis, this study found that the formation of eutectic carbides is dominated by the segregation of elements such as V, Mo, and C during the final stage of solidification, while the chemical composition and three-dimensional morphological evolution of M<sub>2</sub>C-type eutectic carbides are synergistically controlled by the diffusion and competitive growth of elements such as W, Mo, and C in austenite. …”
