    Fabrication and characterization of cadmium sulfide nanowires on aluminum oxide template
    (Umt, Lahore, 2015) Malik Imran Afzal
    Cadmium supplied nanowires have unique electrical and optical properties and applications. To obtain cadmium supplied nanowires with regular and good aspect ratio, they can be synthesized by template synthesis method. Porous anodized aluminium oxide is most promising template with regular hexagonal shapes. Their aspect ratio can be controlled by controlling the pores’ depth and diameter which greatly depend on anodization voltage and temperature of the electrolyte. In this research, high purity aluminium was used to prepare nanotemplates at 5-6°C in 1M phosphoric acid and cadmium supplied was deposited electrochemically using a co-solution of thiourea, cadmium acetate and ammonium acetate. pH was maintained at 11 in heat bath at 75°C with the help of aqueous ammonia solution. Both porous anodized alumina and cadmium supplied Nanowires were characterized suing SEM. A good quality Nanowires were obtained in bunches with reasonably high aspect ratio.

    Nanostructured Composites of Transition Metal Doped Cadmium Chalcogenides with g-C3N4 and their Potential Applications
    (UMT.lahore, 2023-01-11) Malik Imran Afzal
    Advances in modern technologies have drastically changed the globe today but at the expense of severe environmental deteriorations. Emission of greenhouse and toxic gases, industrial, agricultural and household effluents and antibacterial materials used to control the microbial infections have now become an essential but damaging part of our environment. Natural methods of treating the environment like planting more trees are not able to cope with the pollution produced on huge scale in aberrant ways. It has now become crucial to invent new smart catalytic materials for environmental treatment to keep the globe livable. These catalysts materials need to be inexpensive, nontoxic, efficient and stable.
