    Cu‐Co Dual Sites Tandem Synergistic Effect Boosting Neutral Low Concentration Nitrate Electroreduction to Ammonia by Wenhao Yang, Ziwei Chang, Xu Yu, Ping Wu, Ruxiang Shen, Lianzhou Wang, Xiangzhi Cui, Jianlin Shi

    Published 2025-04-01
    “…The designed Cu‐CoP catalyst exhibits an ammonia yield of 7.65 mg h−1 cm−2 and a Faraday efficiency of 85.1% at −1.0 V under neutral low‐concentration nitrate (10 m M), which is the highest ammonia yield in the reported data. In situ characterization and theoretical calculations confirm the tandem synergistic effect, in which the Cu site favors the adsorption and activation of NO3− to form NO2−, and concurrently modulates the electronic structure of the Co site with optimized Hads adsorption resulting in the significantly enhanced NO3−RR at neutral low concentration nitrate.…”

    Cancer-associated VEGFR2R1032Q sustains receptor activation also by promoting ligand-independent hetero-dimerization with co-expressed wild-type VEGFR2 and translocation into lipid... by Cosetta Ravelli, Michela Corsini, Roberto Bresciani, Angela M. Rizzo, Luca Zammataro, Paola A. Corsetto, Elisabetta Grillo, Stefania Mitola

    Published 2025-09-01
    “…This was associated with reduced mobility of the receptor on the membrane, linked to its translocation into detergent-resistant membrane (DRM) domains (e.g. lipid rafts), which showed alterations in lipid compositions and structure. These data shed light on a novel oncogenic mechanism of activation of VEGFR2, clarifying the paradoxical loss-of-function nature of the substitution R1032Q of VEGFR2.…”
