  1. Characterization and electrocatalytic applications of metallophthalocyanine-single walled carbon nanotube conjugates
    Mugadza, Tawanda, 2011
    Metallophthalocyanine-single walled carbon nanotube conjugates were successfully synthesized and applied in the electrochemical characterizations of pesticides (amitrole and diuron) and 2-mercaptoethanol (2-ME). The formation of conjugates was confirmed through the use of the following analytical te ...

  6. Characterization of stratified L-topological spaces by convergence of stratified L-filters
    Orpen, David Lisle, 2010
    For the case where L is an ecl-premonoid, we explore various characterizations of SL-topological spaces, in particular characterization in terms of a convergence function lim: FS L(X) ! LX. We find we have to introduce a new axiom , L on the lim function in order to completely describe SL-topologi ...
