Influence of device architectures and mobility on response/recovery time of metal halide perovskites: A review
(Journal of Materials Science, 2022-01)Organic–Inorganic perovskite materials have attracted great interest in the research community for photo-detector and solar energy applications. For various photo-detector applications, the response time is a very important ... -
Infra-red reflectance and transmittance by thin film coatings of some selected metals on glass substrate
(Kyambogo University(unpublished), 2018-11-14)Reflection and transmission of light serve as key parameters in thin films coatings meant for temperature regulation in warm climates. In this study, the infrared reflectance and transmittance for three different thicknesses ... -
Intensity of secondary scattered x-rays during x-ray diagnostic procedures in selected diagnostic centres in Uganda
(Kyambogo University[unpublished work], 2014-01)The purpose of the study was to investigate the intensity of secondary scattered X-rays when different body regions; the chest, the abdomen and the lower limbs were exposed to X-rays during radiography. The study used ... -
Investigation of the compressive strength of ntawo ball clay fired to different temperatures at different rates of temperature rise
(Kyambogo University (un published work), 2017-12)This study was to investigate the compressive strength of fired Ntawo Ball Clay found in Mukono District in Central Uganda. The clay sample was first analyzed using X-ray Diffraction Spectrometer Model RIX3000 to determine ... -
Investigation of the compressive strength of ntawo ball clay fired to different temperatures for different holding times
(Kyambogo University (un published work), 2017-12)This study focused on ball clay from ntawo deposit from Mukono District, in central Uganda with respect to its compressive strength. The chemical compounds by percentage weight were determined using RIX 3000 Spectrometer ... -
Mechanical properties of ceramic floor tiles made from selected minerals in Uganda
(Kyambogo University [unpublished work], 2012-06)This study was designed to produce porcelain floor tiles using raw materials found in Uganda and to determine mechanical properties of the tiles produced. The properties were then compared with South African National ... -
Natural radioactivity levels and radiological hazard indices of soil and water collected from Kaserem limestone quarry, Kapchorwa district, Uganda
(Kyambogo University (un published work), 2017-10)This study was to determine the gamma ray concentration/activity due to naturally occurring radionuclides present in soil and water from Kaserem limestone quarry area in Kapchorwa District and the associated hazard ... -
Optical absorption and photoluminescence properties of Cucurbita maxima dye adsorption on TiO2 nanoparticles
(IOP Publishing Materials Research Express, 2023-04)Dye-sensitised solar cells (DSSCs) are 3rd generation photovoltaic device that imitate photosynthesis in plants. The fundamental concept of a DSSCs is that the photoanode is covered by the dye as a sensitiser. Natural dyes ... -
Optical activity and faraday effect in some mineral and vegetable oils.
(Makerere University (unpublished work), 2000-03)This Thesis presents results of a study of Optical Activity and Faraday Effect (OAFE) in some mineral and vegetable oils in the temperature range of 6°C to 45°C and magnetic field up to 140mT. Intrinsic birefringences ... -
Performance evaluation of amorphous silicon photovoltaic module using solar light of different wavelengths
