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 formal verification, we verify that a system is correct with respect to a specification. Cases like antecedent failure can make a successful pass of the verification procedure meaningless. Vacuity detection can signal such “meaningless” passes of the specification, and indeed vacuity checks are now a standard component in many commercial model checkers. We address two dimensions of vacuity: ...
