    Synthesis and electrochemical properties of nickel oxide/carbon nanofiber composites حسب Al-Enizi, Abdullah M.

    منشور في 2014
    "…These electrospun fibers were stabilized for 2 h at 200 °C and then carbonized at 800 °C for 5 h. Composites were prepared by depositing Ni(OH)2 on the carbon nanofibers (CNFs) and calcining them at different temperatures. …"

    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. …"

    Thermal behavior and post-heating fracture characteristics of polypropylene microfiber-reinforced geopolymer binders حسب Mohammad R., Irshidat

    منشور في 2022
    "…Geopolymer binders with different fiber contents including 0%, 0.05%, 0.1%, and 0.2% by fly ash weight were prepared and exposed to elevated temperatures of 200 °C, 400 °C, and 600 °C. The effect of fiber reinforcement on the mechanical strengths of unheated binders, residual fracture characteristics of heat-damaged binders, microstructure deterioration, and thermal properties of geopolymer specimens were investigated. …"

    Investigating the utilization of healthcare services to manage respiratory tract infections (RTIs) among Qatari patients attended selected primary healthcare centers in Qatar حسب Islam, Nazmul

    منشور في 2018
    "…Highest number of patients with a comorbidity of Diabetes (12.85%), followed by Hypertension (10.54%). We have found no difference in the month-to-month rates of RTI-related GP visits (per 1000 total visits) over the study period (non-significant decreasing trend). …"

    Enhancing effect of chia seeds on heterocyclic amine generation in meatball حسب Elbir, Zeynep

    منشور في 2023
    "…The impact of using chia seeds at different rates (0%, 0.5%, 1%, and 1.5%) in meatball on the water content, pH and lipid oxidation (thiobarbituric acid reactive substances, TBARS), cooking loss and heterocyclic aromatic amines (HAAs) content of meatballs cooked at 150, 200, and 250 °C was investigated. The chia seed significantly affected water content (P < 0.01), cooking loss (P < 0.05), pH (P < 0.05) and total HAAs content (P < 0.01), whereas no significant impact (P > 0.05) was detected on TBARS value. …"

    Facile Electrochemical Synthesis of Highly Efficient Copper-Cobalt Oxide Nanostructures for Oxygen Evolution Reactions حسب Nath, Narayan Chandra Deb

    منشور في 2020
    "…An optimized nanopetal structure of CuxCo3-xO4 (x = 0.95, annealed at 200 °C) shows a considerably high Faradaic efficiency (∼93%) with a remarkably low overpotential (∼230 mV) at a benchmark current density (J) of 10 mA cm-2; at the same J in an alkaline solution (1 M KOH) for OER, it also exhibits high durability (up to 100 h). …"
