Nitrogen and argon treatment of titanium dioxide nanowire arrays
(University of Western Cape, 2021)TiO2 nanoparticle films are important electron transport layers (ETLs) in photovoltaics such as dye-sensitised, perovskite and polymer hetero-junction solar cells. These films, however, have significant electron trap-sites ... -
Nitrogen and carbon costs of growth and antioxidant production during acclimation to environmental stress in two species of gethyllis
(University of the Western Cape, 2012)Gethyllis multifolia L. Bolus and G. villosa Thunb. are winter-growing, summerblooming,deciduous and bulbous geophytes that grow naturally in the semi-arid succulent Karoo biome of South Africa. Both species grow under ... -

The non-cancellation groups of certain groups which are split extensions of a finite abelian group by a finite rank free abelian group
(University of the Western Cape, 2008)The groups we consider in this study belong to the class X0 of all nitely generated groups with nite commutator subgroups. We shall eventually narrow down to the groups of the form T owZn for some n 2 N and some nite ... -

NON-INVASIVE CHARACTERIZATION OF UNSATURATED ZONE TRANSPORT IN DRY COAL ASH DUMPS: A CASE STUDY OF TUTUKA, SOUTH AFRICA
(University of the Western Cape, 2013)The management of the large volumes of solid wastes produced as coal combustion residue is of particular concern due to the presence of leachable metals and salts which may constitute a long term environmental risk and ... -
Nonlinear low frequency wave phenomena in space plasmas
(University of the Western Cape, 2013)In this thesis, using multispecies fluid plasma models, nonlinear electrostatic solitary wave fluctuations will be investigated in magnetized plasmas. The different models used for the investigation will be guided by the ... -
Nonlinear optical properties of natural dyes based on optical resonance
(University of the Western Cape, 2012)Recent research shows that the study of optical properties of organic material natural dyes has gained much consideration. The specific functional groups in several natural dyes remain essential for the large nonlinear ... -

Normalization and statistical methods for crossplatform expression array analysis
(University of the Western Cape, 2012)A large volume of gene expression data exists in public repositories like the NCBI’s Gene Expression Omnibus (GEO) and the EBI’s ArrayExpress and a significant opportunity to re-use data in various combinations for novel ... -
Novel 3-mercaptopropionic acid capped iridium selenide quantum dots modified electrochemical immunosensor for the detection of fish toxin, nodularin
(University of the Western Cape, 2012)A novel 3-mercaptopropionic acid capped iridium selenide quantum dots based label free impedimetric immunosensor was successfully constructed. The 3-mercaptopropionic acid capped iridium selenide quantum dots synthesized ... -
Novel adamantane derivatives as multifunctional neuroprotective agents
(University of the Western Cape, 2013)The pathology of neurodegenerative disorders involves multiple steps, and it is probably for this reason that targeting one particular step in a multi-step process has only yielded limited results. Nitric oxide (NO) is ... -
Novel adamantane-chloroquinolin conjugates to overcome plasmodium falciparum chloroquine resistance
(University of the Western Cape, 2017)Malaria poses devastating health and socioeconomic outcomes on global health especially among pregnant women and children below the age of 5 in endemic areas. This is exacerbated by Plasmodium falciparum resistance to ... -
Novel aminoquinoline-polycyclic hybrid molecules as potential antimalarial agents
(University of the Western Cape, 2014)Plasmodium falciparum malaria continues to be a worldwide health problem, especially in developing countries in Africa and is responsible for over a million fatalities per annum. Chloroquine (CQ) is low-cost, safe and was ... -
Novel approach of using Hydrogeochemistry, Hydrogeologic and Hydrostratigraphic techniques in evaluating coastal aquifers in Heuningnes catchment, South Africa
(University of the Western Cape, 2019)The increasing population in search for better social and economic development in coastal areas puts groundwater resources under pressure because of the high fresh water demand for domestic and agriculture use. Seawater ... -
Novel aromatic dendritic-co-poly(3-hexylthiophene) composites for photovoltaic cell application
(University of Western Cape, 2021)Fossil fuels are part of fuels that are formed from natural processes and they are called non-renewable sources of energy. These include natural gas, coal and oil. They have been used for decades to produce energy globally. ... -
Novel genomic approaches for the identification of virulence genes and drug targets in pathogenic bacteria
(University of the Western Cape, 2001)While the many completely sequenced genomes of bacterial pathogens contain all the determinants of the host-pathogen interaction, and also every possible drug target and recombinant vaccine candidate, computational tools ... -
