Can the mechanical activation (polishing) of screen-printed electrodes enhance their electroanalytical response?
(2016-05-07)
The mechanical activation (polishing) of screen-printed electrodes (SPEs) is explored and shown to exhibit an improved voltammetric response (in specific cases) when polished with either commonly available alumina slurry ...
1-Heptyne semihydrogenation catalized by palladium or rhodium complexes. Influence of: metal atom, ligands and the homo/heterogeneous condition
(Elsevier Science, 2007-07)
[RhCl(TDA)3], [RhCl(HA)3], [PdCl2(TDA)2] and [PdCl2(HA)2] (TDA = tridecylamine, HA = hexylamine) were synthesized and tested as catalysts in homogeneous and heterogeneous condition for the 1-heptyne semihydrogenation, using ...
