    Published 2025-06-01
    “…Adsorption data were modeled using Langmuir, Freundlich, and Dubinin-Radushkevich isotherms, indicating monolayer adsorption consistent with the Langmuir model. The adsorption mechanism involves a two-step process where positively charged Cd2⁺ and Pb2⁺ ions diffuse toward the negatively charged surface of the Alg-OP-Ni nanobiocomposite and subsequently fix through interactions with surface oxygen atoms. …”

    Balancing act: optimizing blue light for melanogenesis while minimizing cellular damage in primary human skin cells by Augustin C. Barolet, Augustin C. Barolet, Augustin C. Barolet, Augustin C. Barolet, Brice Magne, Brice Magne, Brice Magne, Karel Ferland, Karel Ferland, Karel Ferland, Natallia E. Uzunbajakava, Daniel Barolet, Daniel Barolet, Lucie Germain, Lucie Germain, Lucie Germain

    Published 2025-01-01
    “…IntroductionRecent findings show that visible light, particularly blue light, stimulates melanogenesis in human skin, though the underlying mechanisms remain debated. This study aimed to determine the cell damage threshold of non-ionizing blue light on keratinocytes while preserving their ability to stimulate melanogenesis.MethodsHuman keratinocytes (N = 3) and melanocytes (N = 3) were isolated from skin samples of varying Fitzpatrick skin phototypes and irradiated with blue light (λpeak = 457 nm) and UVA light (λpeak = 385 nm). …”

    Unidirectional freeze–thaw redistributes water and amplifies soil microbial heterogeneity in a mecrocosm experiment by Huimin Liu, Yaxian Hu, Yuan Song, Xianwen Li, Xiaorong Wei

    Published 2025-01-01
    “…Such unidirectional freeze–thaw induced soil water redistribution tended to alleviate the dryness in the L1 of the low moisture columns initially with 30% of water holding capacity (WHC), but rendered the L1 of the high moisture columns (initially with 80% WHC) more susceptible to intensive mechanical destruction during ice crystallization. On the contrary, the water depletion in the inner layer L6 appeared to introduce secondary dry stress to the low moisture columns, but helped to temper the destructive ice expansion in the L6 of the high moisture columns. …”
