(University of Pretoria, 2011-09-23)An electrocatalyst plays an important role in the alcohol oxidation reaction in fuel cells. Palladium based electrocatalysts are one of the promising candidates for alcohol oxidation in direct alcohol alkaline fuel cells. ...
-
(University of Pretoria, 2019)This work gives a thorough insight into the objectivity of adapting the sequential injection analysis (SIA) technique as a tool for chemical speciation. The use of ultraviolet visible spectrophotometry as a single detector ...
-
(University of Pretoria, 2016)This thesis reports on the study of carbon nanomaterials integrated with nanostructured birnessite-type MnO2 and tetragonal hausmannite-type Mn3O4 as electrode materials for enhanced performance in symmetric pseudocapacitors. ...
-
(University of Pretoria, 2008-07-07)O-ethyl S-2-diisopropylaminoethyl methylphosphonothiolate (VX) and O-isobutyl-S-2-diethylaminoethyl methylphosphonothioate (R-VX), are considered chemical warfare agents due to their strong acetylcholinesterase-inhibiting ...
-
(University of Pretoria, 2012)The investigation of the kinetics of fuel cell (FC) molecules such as methanol (MeOH), ethylene glycol (EG) and formic acid (FA) on platinum (Pt), platinum/ruthenium (PtRu) and platinum based metal complexes (ruthenium ...
