Synthesis of ZnO nanorods modified with TPP, TPPS and Cu-TPPS for photodegradation of MB

open access: yesProceedings of The 17th International Electronic Conference on Synthetic Organic Chemistry, 2013
In this study, ZnO nanorods have been synthesized by a simple precipitation technique with zinc nitrate as starting material in the presence of ammonium hydroxide followed by calcination at 450 ˚C. Then meso-tetrakis(4-phenyl) porphyrin (TPP), meso-tetrakis(4-sulfonatophenyl) porphyrin (TPPS), and Copper meso-tetrakis(4-sulfonatophenyl) porphyrin (Cu ...

Search and test algorithms for Triple Product Property triples

open access: yes, 2011
In 2003 COHN and UMANS introduced a group-theoretic approach to fast matrix multiplication. This involves finding large subsets of a group $G$ satisfying the Triple Product Property (TPP) as a means to bound the exponent $\omega$ of matrix multiplication.
