(2007)In this study, the capabilities of Neutron Radiography (NRad) and -Tomography (NTomo), as well as X-ray Radiography (XRad) to investigate chlorides and chlorides corrosion effects within steel reinforced laboratory concrete ... -
Development and characterization of bioceramic coatings for medicall and dental applications
(University of the Western Cape, 2007)Hydroxyapatite (HA), which is a natural component of bone tissue, is already being marketed as a coating for the metal shafts of hip implants as well as dental screws and other endoprostheses with the expectation of improved ... -
Radiometric study of soil: the systematic effects
(University of the Western Cape, 2007)The natural 238U, 232Th and 40K radioactive content of vineyard soil was measured with an in-situ gamma-ray detector. The activity concentrations measured with the in-situ detector are normalized using the laboratory-determined ... -
Low temperature growth of Amorphous Silicon thin film
(University of the Western Cape, 2007)The growth of amorphous hydrogenated silicon (a-Si:H) thin films deposided by hot wire chemical vapor deposition (HWCVD) has been studied. The films have been characterised for optical and structural properties by means ... -
In-situ measurements of radon concentrations in soil gas at a site on the Cape Flats
(University of the Western Cape, 2007)Measurements of radon (222Rn) concentration in soil gas are routinely used to locate geological fault zones. This study was undertaken to investigate the systematic effects that influence radon soil-gas measurements, in ... -
Signature splitting and inversion in the 186-194 Au Nuclei predicted by the total routhian surface (TRS) and cranked shell model (CSM) calculations
(University of the Western Cape, 2007)The nearly oblate deformed Au nuclei show rotational bands built on multi quasiparticle excitations [Bou89, Bou92, Gue03, Gue01, Ven92]. Several of these bands are built on rotationally aligned high-j proton and neutron ... -
Search for tetrahedral bands in yb isotopes
(University of the Western Cape, 2007)Calculations by Dudek et al. predict shell gaps for tetrahedrally shaped nuclei at various proton and neutron numbers. 160Yb is expected to be a favourable nucleus, with tetrahedral bands predicted to lie 1 MeV above the ... -
Using internet -enabled remote instrumentation for research and training in physics: Evaluation of different diffusion barriers for silver metallization
(University of the Western Cape, 2007)The growth of the Internet has led to many interesting developments for both educational and commercial purposes. In this project an attempt was made to use the Internet for a research purpose to facilitate the determination ... -
Electrical resistivity of the kondo systems (Ce1−xREx)In3, RE = Gd, Tb, Dy AND Ce(Pt1−xNix)Si2
(University of the Western Cape, 2008)The present study investigates the strength of the hybridization by substituting Ce atom in Kondo lattice CeIn3 with Gd, Tb, and Dy and by changing the chemical environment around the Ce atom in substituting Pt with Ni in ... -
The determination of boron using 11B(p, α)8Be nuclear reaction
(UWC, 2008)Determination of trace quantities of boron is required in various studies of materials and in geology. Using 11B(p, α)8Be nuclear reaction with focused proton beam of 670 keV energy is one of the few microanalytical ... -
