in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...

Paths are the most important urban spaces and account for the city and its historic district’s main structure. In the past, the geometry of historic cities revolved around old bazar rows and passages. However, with the advent of motorized vehicles and subsequent chess roads in historical texture, organic geometry and hierarchy of paths net, integrity and structure of historic district were disr...
