The antioxidant and anticancerous activities of native and microwave roasted barley flour were compared in three different solvents (methanol, ethanol and water) using various antioxidant assays. The extracting solvents significantly affected the antioxidant potential and inhibition of DNA damage capabilities of barley flour extracts. Among the different solvents methanol was found to be the mo…
Water, it is said, will be the oil of the twenty-first century. Successful water management will be the key to future economic growth and social wealth in both developed and developing countries. Due to the continuous agricultural expansion, urban development, and increased demands on limited water supplies, Egypt is compelled to look for unconventional water resources. One of the most importan…
a b s t r a c t Hydrous ruthenium oxide/activated carbon black (RuOx/ACB) composite was synthesized for the first time for supercapacitors by a chemical impregnation method. The RuOx/ACB composite is characterized by thermogravimetric analysis (TGA), field emission scanning electron microscope (FE-SEM) and transmission electron microscope (TEM). The results of TGA and TEM characterization s…
Abstract The specific energy, specific power, fast-charge capability, low temperature operation, cycle-life and self-discharge of five energy storage devices was compared. The group included a conventional carbon–carbon supercapacitor, Li-ion battery and three types of asymmetric hybrid supercapacitors. Asymmetric hybrid supercapacitors use a nanostructured Li4Ti5O12 anode, and an acetonitri…
