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...

In order to study the effect of zero-valent iron nanoparticles on morphological and physiological traits of canola (Brassica napus L. cv. 'Hayola 401') under salinity stress, a research was conducted under controlled conditions in factorial based on completely randomized design in three replicates. In the first phase, the zero-valent iron nanoparticles were synthesized and in the second phase, ...
