In Chongwe at the site proposed for the Centre for Nuclear Science and Technology (CNST) soil, plant and water samples from the dam nearby had the activity concentrations of natural radionuclides measured. The natural radionuclides whose activity concentrations were measured are Uranium-238...

This dissertation reports on the deposition of ZnO prepared by sol-gel on substrates by spin-coating, and the characterisation of the resulting thin films. The precursor solution was synthesized using appropriate quantities of aqueous Zinc Acetate dehydrate, 2- Methoxyethanol and Ethanolamine....

An important aspect in the development of semiconducting devices for use in photovoltaic systems is the design of materials with appropriate band gaps. Electronic structure calculations based on Density Functional Theory (DFT) have been extensively used to study and to describe such properties of...
