Abstract
With the recent advances in modern technologies, the mass production and widespread use of electronic devices have led to a considerable increase in electronic waste (E-waste), creating a crucial need for efficient and environmentally sustainable E-waste recycling. Conventional metal recovery techniques, including pyrometallurgical and hydrometallurgical processes, often suffer from low..... More

Abstract
The effect of TiO₂ additive concentration and sintering temperatures on the densification of alumina (Al₂O₃ ) ceramics were investigated. Densified alumina specimens were prepared by uniaxial pressing at a pressure of 60 MPa followed by isothermal heating at either 1400, 1500, or 1600 o C for 2 h. The relative..... More

Abstract
ZnSe quantum-dots were synthesized in an aqueous system and UV irradiation was introduced as a post-treatment process. The synthesis temperature was varied from 25 ^oC to 90 ^oC, and the surface of the nano powder was stabilized using different ligands such as glutathione (GSH), 3-mercaptopropionic acid (MPA) and thioglycolic acid.....
