Phenotypic and molecular characteristics of Methicillin-resistant Staphylococcus Aureus isolates from stored patient samples in Misurata hospitals and poultry from commercial markets, Libya
(University of the Western Cape, 2019)The emergence of virulent and drug-resistant bacterial strains such as methicillin-resistant Staphylococcus aureus (MRSA) is a global public health burden. The World Health Organization (WHO) has placed MRSA and ... -
Photo-physical properties of lead-tin binary Perovskite thin films
(University of Western Cape, 2021)Organic-inorganic lead-based perovskite has exhibited great performance in the past few years. However, the lead (Pb) embedded in those compounds is a significant drawback to further progress, due to its environmental ... -
Photocatalytic activity of supported TiO2 nanocrystals
(2013)In recent times, the occurrence and presence of complex recalcitrant toxic contaminants in water and wastewater is increasing and consequently contributes to the non-availability of clean and safe drinking water. Water ... -
Photocatalytic degradation of organic pollutants using Ag-Fe₃O₄/SiO₂/TiO₂ nanocomposite
(University of the Western Cape, 2015)The global lack of clean water for human sanitation and other purposes has become an emerging dilemma for human beings. The presence of organic pollutants in wastewater produced by textile industries, leather manufacturing ... -
Photoluminescent Responses of Polypropylenethiophenoimine-Co-Pedot/ Polystyrenesulfonic Acid and Zinc Selenide Quantum Dot Composite Materials
(University of the Western Cape, 2018)Research in renewable energy has gained momentum and become a centre of attention as a possible alternative solution to the energy catastrophe. This is attained by the use of solar energy as an alternative clean energy ... -
