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

    Published 2025
    “…However, how global land use changes impact soil N supply and potential N loss remains elusive. 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. …”

    Synthesis of polymers 5 and 6. by Ghadeer Mubarak (21567569)

    Published 2025
    “…The results showed that AMCs act as efficient corrosion inhibitors, with over 90% inhibition efficiency ( ) at 20 ppm concentration. The electrochemical investigation results indicated that the AMCs with hydrophilic and hydrophobic ratios of 100 (<b>5</b>), 90:10 (<b>6a</b>), and 80:20 (<b>6b</b>) manifest of 87.74%, 92.12%, and 93.53%, respectively. …”
