    Long-term performance analysis and power prediction of PV technology in the State of Qatar حسب Touati F.

    منشور في 2017
    "…Results show that due to panel dusting for eight months, the PV output power decreased by 50%. Also, owing to lower ambient temperatures, clearer sky and cleaner panels due to occasional rainfall, the PV panels show higher output power in Winter than in Summer season. …"

    Cyclic voltammetry and XPS studies of poly (aniline-co-3-aminophenol) حسب Waware, Umesh Somaji

    منشور في 2022
    "…In the electrochemical study, the copolymers differ from PA in the single-electron oxidation and reduction, reversibly at various scan rates ranging from 20 to 50 mV. The current density decreases from PA-co-3-AP20 to PA-co-3-AP80 by increasing the loading weight percentage of 3-aminophenol in the polymeric backbone. …"

    Effect of surfactant and electron treatment on the electrical and thermal conductivity as well as thermal and mechanical properties of ehylene vinyl acetate/expanded graphite compo... حسب Sefadi, Jeremia Shale

    منشور في 2015
    "…The thermal conductivity linearly increased with EG content, and this increase was more pronounced in the case of SDS-EG, but decreased after EB irradiation. The thermal properties were little influenced by EB irradiation, while better polymer–filler interaction and better filler dispersion as a result of SDS treatment, and the EB irradiation initiated formation of a cross-linked network, had a positive effect on the tensile properties.…"
