    Bi2MoO6/Fe-MOF nanocomposites: An efficient adsorbent for chlortetracycline, oxytetracycline, and doxycycline in water by Bai Sun, Yiming Shi, Haiyan Zhou, Chengqi Ye, Yuxian Guo, Yun Wang, Lining Bao, Xiangxiang Wang, Mingjian Yi, Shuguang Zhu

    Published 2025-04-01
    “…The comprehensive kinetic study revealed that the adsorption of BFeM on the three antibiotics was primarily chemical adsorption (pseudo second-order kinetics) and intragranular diffusion. The adsorption isotherms showed that the adsorption of BFeM on the three antibiotics followed the Langmuir adsorption isotherm model, indicating mainly monolayer adsorption. …”

    Transverse dynamics of charmed hadrons in ultra-relativistic nuclear collisions by Anton Andronic, Peter Braun-Munzinger, Hjalmar Brunßen, Jana Crkovská, Johanna Stachel, Vytautas Vislavicius, Martin Völkl

    Published 2024-10-01
    “…The observed wide distribution in p T of anisotropic flow coefficients v2 and v3 for charmonia is also well reproduced, while their magnitude is generally somewhat over predicted. This finding may be connected to a difference in spatial distribution between light and charmed hadrons due to a different diffusion of light and heavy quarks in the hot fireball.…”

    Three Solutions for a Double-Phase Variable-Exponent Kirchhoff Problem by Mustafa Avci

    Published 2025-07-01
    “…In this article, we study a double-phase variable-exponent Kirchhoff problem and show the existence of at least three solutions. The proposed model, as a generalization of the Kirchhoff equation, is interesting since it is driven by a double-phase operator that governs anisotropic and heterogeneous diffusion associated with the energy functional, as well as encapsulating two different types of elliptic behavior within the same framework. …”

    Remote Sensing Survey of Chlorophyll-a Concentration in River-Type Reservoirs Based on GF-1 Image Data: Taking Feilaixia–Changhu Reservoir Area as an Example by ZOU Zhengxin, DENG Ruru, LIANG Yeheng, CHAI Zhuoqun, KUANG Zhiyuan, YANG Junying, ZHAO Zixi

    Published 2025-01-01
    “…The high-concentration pollution areas in the reservoir center of Feilaixia Reservoir and the main stream are temporary, because the hydrodynamic conditions are formed with the migration of river diffusion; while the pollutants located in the reservoir bay and river bay are gathered into stable pollution areas due to their poor flow conditions, indicating that the Deng model has also achieved good results under dynamic hydrological conditions. …”

    Published 2025-09-01
    “…If there is heterogeneity between studies, the random effect model is used. I2index is one of the important indices in determining the degree of heterogeneity between studies.In general, the degree of heterogeneity in the I2index is determined in the following three ways: I2≤25% indicates low heterogeneity. 50 ≤I2≤ 75% indicates moderate heterogeneity; that is, half of the total variability among effect sizes is not due to sampling error and is due to heterogeneity between studies.and I2≥ 75% indicates high heterogeneity (Higgins & green, 2011)Among more than 60 domestic studies and 28 foreign studies. …”

    Competitive Adsorption of Metals onto Magnetic Graphene Oxide: Comparison with Other Carbonaceous Adsorbents by Jin Hur, Jaewon Shin, Jeseung Yoo, Young-Soo Seo

    Published 2015-01-01
    “…Irrespective of the adsorbents, the adsorption was highly dependent on pH, and the adsorption was well described by the Langmuir isotherm model. The maximum adsorption capacities of the adsorbents were generally higher in the order of Pb(II) > Cu(II) > Cd(II), which is the same as the degree of the electronegativity and the hydrated radius of the metals, suggesting that the metal adsorption may be governed by an ion exchange between positively charged metals and negatively charged surfaces, as well as diffusion of metals into the surface layer. …”

    Published 2025-07-01
    “…We discover widespread PopA homologues, including likely tetramers and hexamers, that retain the lipid chamber; a similar chamber is formed by an unrelated smaller closed-barrel family, implicating this as a general feature. Our work thus defines oligomeric OMP superfamilies, whose deviation from prior structures requires us to revisit existing membrane-interaction motifs and folding models.…”
