Latent and thermal energy storage enhancement of silver nanowires-nitrate molten salt for concentrated solar power
Maaza, Malik (University of Western Cape, 2020)Phase change material (PCM) through latent heat of molten salt, is a convincing way for thermal energy storage in CSP applications due to its high volume density. Molten salt, with (60% NaNO3 and 40% KNO3) has been used ... -
Low temperature tungsten trioxide nano/micro-systems for applications in gas sensing and electrochromism
Tumbain, Sone Bertrand (2013)In this work we primarily set out to investigate the technique of Aqueous Chemical Growth as a means of producing WO3 thin films that find applications in gas sensing and electrochromism. For the first time we demonstrated ... -
Nano-rods WO3-δ for electrochromic smart windows applications
Sibuyi, Praise (University of the Western Cape, 2006)Tungsten oxide is a good electrochromic material which has been used in the construction of smart windows through visible modulation. These smart materials can reversibly change their optical properties with the application ... -
Nonlinear optical properties of natural dyes based on optical resonance
Zongo, Sidiki (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 ... -
Photo-physical properties of lead-tin binary Perovskite thin films
Mabiala, Floyd Lionel (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 ... -
Physical properties of vanadium dioxide nanoparticles: application as 1-d nanobelts room temperature for hydrogen gas sensing
Simo, Aline (University of the Western Cape, 2013)Transition metal oxides magneli phases present crystallographic shear structure which is of great interest in multiple applications because of their wide range of valence, which is exhibited by the transition metals. The ... -
Spectrally selective AlXOY/Pt/AlXOY solar absorber coatings for high temprature solar-thermal applications
Nuru, Zebib Yenus (University of Western Cape, 2014)The limited supply of fossil hydrocarbon resources and the negative impact of CO2 emission on the global environment dictate the increasing usage of renewable energy sources. Concentrating solar power (CSP) systems are the ... -
Synthesis of bimetallic immiscible alloy nanoparticles through green and gamma radiolysis approaches for environmental remediation applications
Noukelag, Sandrine Kamdoum (University of the Western Cape, 2022)The synthesis of bimetallic immiscible alloy nanoparticles (NPs) using versatile routes, is a major concern since physio-chemical methods are not environmentally benign. Breaking down the immiscibility would generate NPs ... -
Thermochromic properties of VO2 nano-coatings by inverted cylindrical magnetron sputtering
Madiba, Itani Given (University of the Western Cape, 2012)Vanadium dioxide (VO2) films have been known as the most feasible thermochromic nano-coatings for smart windows which self control the solar radiation and heat transfer for energy saving and comfort in houses and automotives. ... -
Towards stimuli-responsive functional nanocomposites: smart tunable plasmonic nanostructures Au-VO2
Kana, Jean Bosco Kana (University of the Western Cape, 2010)The fascinating optical properties of metallic nanostructures, dominated by collective oscillations of free electrons known as plasmons, open new opportunities for the development of devices fabrication based on noble metal ... -
Vanadium dioxide nanocomposite thin film embedded in zinc oxide matrix as tunable transparent conductive oxide
Sechogela, Thulaganyo P. (University of the Western Cape, 2013)This project is aimed at fabricating a smart material. Zinc oxide and vanadium dioxide have received a great deal of attention in recent years because they are used in various applications. ZnO semiconductor in particular ...
