In this paper, the purest kind of  Gum Arabic, extracted from (Hashab) trees (in western Sudan ), is used in concrete mixes after crushing to be in a form of powder which was dissolved in water to get the liquid…

Dropping of pressure drop (PD) across the spouted bed could reduce the dissipated pumping energy and improve stability and uniformity of solid particles. The selected decision variables are; gas velocity, solid's density and solid's diameter. Steady-state measurements were carried out…

Friction Stir Welding being a solid-state process is free from defects generally occurs in fusion welding process. FSW of Stainless Steel is done on retrofitted vertical milling machine. For this welding operation a fixture is needed on which the plates…

The increasing costs of electric energy and thus the need to reduce the energy required to produce ferrochrome from chromite ore have spurred the innovations in the technologies used for smelting chromite ore. These technologies (Conventional smelting process, Outokumpu process,…

The zero band gap (Eg) graphene becomes narrow Eg semiconductor when graphene is patterned with periodic array of hexagonal shaped antidots, the resultant is the hexagonal Graphene Antidot Lattice (hGAL). Based on the number of atomic chains between antidots, hGALs…
