    Thermal and mechanical stability of microwave sintered cold compact bismuth telluride thermoelectric material حسب Farheen F., Jaldurgam

    منشور في 2022
    "…The compacted pellets were sintered in a microwave at 250 °C and 300 °C. Thermogravimetric analysis (TGA), and differential scanning calorimeter (DSC) analysis were performed to study the thermal stability, and nanoindentation, compression test, and microhardness tests were done for mechanical stability. …"

    Hydrogen Production via Ethanol Decomposition over Bimetallic Catalyst حسب Ashok, Anchu

    منشور في 2016
    "…Ethanol decomposition over bimetallic CuCo were conducted using in situ diffuse reflectance infrared fourier transform spectroscopy (DRIFT) study under N2 flow at different temperatures (50, 100, 200, 300, 400°C). Temperature-time profile of CuCo shows an increase in combustion temperature with increase in fuel ratio with maximum temperature at φ = 1 (stoichiometric ratio) and after that it decreases. …"

    Conversion of Organic Municipal Wastes into Biochars and their Effect on Fertility Parameters of Normal and Sabkha Soils of Qatar حسب Ahmedna, Mohamed

    منشور في 2016
    "…Biochars produced from mixed materials pyrolyzed at 500–750°C for 4–6 hours of pyrolysis time and used 2% application rate are best for amendment of normal soil while soft and mixed materials pyrolyzed at 300–500°C for 4 hours and used at 0.5–1% application rates as most suitable for the amendment of sabkha soil. …"
