    Tailoring the defects of sub-100 nm multipodal titanium nitride/oxynitride nanotubes for efficient water splitting performance حسب Eid, Kamel

    منشور في 2021
    "…These defects decreased the bandgap energy to 2.4 eV, increased visible-light response, and enhanced the incident photon-to-current collection efficiency (IPCE) and the photocurrent density of TiONxNTs by nearly 8 times compared with TiO2NTs, besides a quick carrier diffusion at the nanotube/electrolyte interface. …"

    Impacts of rural tourism-driven land use change on ecosystems services provision in Erhai Lake Basin, China حسب Li, Jinghui

    منشور في 2020
    "…With these land changes, ecosystem services also changed greatly, to the detriment of ELB as a whole and especially the lakeside zone. By 2015, soil retention had decreased and nitrogen and soil export had increased, compared with the levels in 2000, while there was only a slight fluctuation in carbon storage and water yield. …"

    Influence of changing casing groove parameters on the performance of centrifugal compressors near stall condition حسب Halawa, Taher

    منشور في 2016
    "…Results showed that by increasing the number of grooves, the surge margin (SM) increases and the isentropic efficiency decreases, but the stall area at the shroud surface decreases in size and its location is shifted toward the blades trailing edge.…"
