Investigation of the Sustainable Production and Utilization of Biochar and Activated Carbon From Waste حسب Farah Yousef Taher Obar (19938288)

"…After activation, the SCG biomass was used to produce biochar by a slow pyrolysis process at three temperatures (300, 500, and 600 °C) for 1-hour residence time and at a heating rate of 5 °C/min. The various physico-chemical properties of activated carbon at three different temperatures were analyzed to select the most suitable one for the batch adsorption study. …"

Visible Light Photocatalytic Activity of Ag/WO₃ Nanoparticles and its Antibacterial Activity Under Ambient Light and in The Dark حسب Maha Matalkeh (17148358)

"…HRTEM, XPS analysis shows that the photocatalyst has a large sheet-like morphology with well-dispersed small metallic Ag particles (<3 nm) on the WO₃ nanoparticle's surface, with most particles near the edges. Ultraviolet–visible spectra analysis observed a large redshift in the absorbing band edge and decreased bandgap energy from 2.6 to 2.1 eV. …"
