nanometric carbid silicon (sic) supported monometallic and bimetallic catalysts containing fe, co, ni transition metals were prepared by wet impregnation method. multiwall carbon nanotubes (mwcnts) were synthesized over the prepared catalysts from catalytic decomposition of acetylene at 850°c by thermal chemical vapor deposition (tcvd) technique. the synthesized nanomaterials (catalysts and cnt...

Investigation of new calculate depends on the controlled optical properties of nanomaterials. Understanding the growth mechanism and growth parameters of nanostructured materials is essential. ZnO is one of the most important semiconductor materials for its semiconducting characteristics. In the present paper, we investigated a new model by theoretical methods; it is based on correlation from t...

Abstract Nickel-catalyzed cross-coupling and photoredox catalytic reactions has found widespread utilities in organic synthesis. Redox processes are key intermediate steps many cycles. As a result, it is pertinent to measure document the redox potentials of various nickel species as precatalysts, catalysts, intermediates. The transition-metal complex governed by its oxidation state, ligand, sol...
