Submitted: 16 February 2026 You are already at the latest version Field-scale nitrogen migration mechanisms in small watersheds remain poorly quantified due to insufficient representation of microtopographic heterogeneity. This study investigates nitrogen transport dynamics in a 1.27 km² agricultural watershed in China's Jianghuai region using UAV-derived 0.1 m DEMs and coupled hydrological-erosion modeling.

Given the distinctive optical scattering and surface plasmon resonance properties of silver nanocrystals, which can effectively manipulate the propagation path of incident light and enhance the local field effect, this study innovatively designed and fabricated a series of violet-excitable phosphor films embedded in $({\rm Sr},{\rm Ca}){{\rm AlSiN}_3}{:}{{\rm Eu}^{2 +}}$ glass doped with silver nanocrystals.

1 Introduction The overreliance on global fossil fuel resources has resulted in significant environmental pollution and growing concerns over resource scarcity, underscoring the urgent need for alternative, sustainable energy sources.[1] Solar and wind power, among other renewable energy options, are widely recognized as environmentally friendly solutions with significant potential for future electricity generation and environmental preservation.
