    Oxidative Nickel-Catalyzed <i>ortho</i>-C–H Amination of (Iso)quinolines with Alicyclic Amines Directed by a Sacrificial <i>N</i>‑Oxide Group حسب Weiqi Zhu (17845973)

    منشور في 2024
    "…Transition metal (TM)-catalyzed direct amination of C–H bonds on free or fused pyridine (Py) rings with free amines still remains scarce because amines and the Py ring tend to adopt a nonproductive N-bound coordination with many TMs, leading to a significant decrease of catalytic reactivity. We herein disclose a nickel-catalyzed and a sacrificial <i>N</i>-oxide group directed oxidative coupling of (iso)quinolyl C–H bonds and alicyclic amines, which furnishes bioimportant amino(iso)quinolines efficiently and selectively in a single step. …"

    Global Land Use Change Impacts on Soil Nitrogen Availability and Environmental Losses حسب Jing Wang (6206297)

    منشور في 2025
    "…By compiling a global data set of 1,782 paired observations from 185 publications, we show that land use conversion from natural to managed ecosystems significantly reduced NNM by 7.5% (−11.5, −2.8%) and increased NN by 150% (86, 194%), indicating decreasing N availability while increasing potential N loss through denitrification and nitrate leaching. …"

    Chitosan-Based Thermal-Coagulation Hydrogel System Driven by Multiple Interactions: Oxidation-Induced Fast Gelation and Enhanced Performance حسب Yifan Liu (219681)

    منشور في 2025
    "…By controlling the grafting rate, it was found that the solution pH and p<i>K</i><sub>a</sub> of CS-C were both affected by the decrease of the amino groups, whereas the gelation time and the required β-GP content for gelling significantly decreased. …"
