The effect of flow field design on the degradation mechanisms and long term stability of HT-PEM fuel cell
(University of the Western Cape, 2018)
Fuel cells are long term solution for global energy needs. In current fuel cell
technologies, Proton Exchange Membrane (PEM) fuel cells are known for quick start-up
and ease of operation compared to other types of fuel ...
Thermochemical Storage and Lithium Ion Capacitors Efficiency of Manganese-Graphene Framework
(University of the Western Cape, 2018)
Lithium ion capacitors are new and promising class of energy storage devices formed from a combination of lithium-ion battery electrode materials with those of supercapacitors. They exhibit better electrochemical properties ...
Chromium and Titanium based Stannum Nanocomposites materials as electron acceptors for next generation bulk Heterojunction photovoltaic cells
(University of the Western Cape, 2018)
Renewable energy has become the centrepiece of research in resolving the energy

etc. The study of nano-sized ...
Molecularly imprinted polymer sensor systems for environmental estrogenic endocrine disrupting chemicals
(University of the Western Cape, 2018)
There is growing concern on endocrine disrupting compounds (EDCs). The presence of drugs
in water supplies was first realized in Germany in the early 1990s when environmental
scientists discovered clofibric acid. Clofibric ...
Metallic nanoparticles with polymeric shell: A multifunctional platform for application to biosensor
(University of the Western Cape, 2018)
Tuberculosis (TB) is an airborne disease caused by Mycobacterium tuberculosis (MTB) that
usually affects the lungs leading to severe coughing, fever and chest pains. It was estimated
that over 9.6 million people worldwide ...
Development of Metal Nanoparticle-Doped Polyanilino-Graphene Oxide High Performance Supercapacitor Cells
(University of the Western Cape, 2018)
Supercapacitors, also known as ultracapacitors or electrochemical capacitors, are considered
one of the most important subjects concerning electricity or energy storage which has proven
to be problematic for South Africa. ...
