The nature of the microjy source population
(University of the Western Cape, 2015)
The study of the faint radio universe and of its properties has recently become a very active field of research not only because of the much improved capabilities of the SKA pathfinders but also because of the need to ...
Magnetic substitution in CePt₂Si₂ and CeCu₅In Kondo lattice
(University of the Western Cape, 2013)
In the past few decades, the studies of f-electron materials have revealed unusual physical properties such as Fermi-liquid, non-Fermi-liquid behaviour at low temperatures, heavy- Fermion behaviour, valence fluctuation, ...
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 ...
Thermochromic properties of VO2 nano-coatings by inverted cylindrical magnetron sputtering
(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. ...
Nuclear level densities and gamma-ray strength functions in Ta isotopes and nucleo-synthesis of ¹⁸ᴼTa
(University of the Western Cape, 2016)
Most stable and extremely low abundance neutron deficient nuclei with Z ≥ 34 are referred to as p-nuclei. Nearly all p-nuclei with A < 110 are most likely produced in the rp-process while almost all A > 110 are thought ...
The effects of environment on radio-loud AGN activity in Stripe 82
(University of the Western Cape, 2016)
We investigate the link between environment and radiative accretion efficiency using a sample of 8946 radio-loud AGN detected at 1 − 2 GHz in the SDSS Stripe 82 region. We quantify their environments using the surface-density ...
Hydrogen storage in Ti-based coatings and Ti6Al4V alloy
(University of the Western Cape, 2016)
Hydrogen has been regarded as an ideal energy carrier for future, it can be stored as a liquid in cryogenic tanks, a gas in high pressure cylinders and as solid in metal hydrides. Hydrogen storage in metal hydrides is of ...
Exploration of several radiation-based analytical techniques to investigate chlorides and chlorides effects within concrete
(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 ...
Probing the large-scale structure of the universe with correlation functions
(University of the Western Cape, 2014)
In this project we explore a new statistical package called KSTAT that computes the 2PCF and higher order correlation functions, such as the 3PCF, on BOSS, making use of high performance computing facilities to improve ...
Synthesis and characterisation of 114Cd targets
(2011)
To study nuclear reactions and nuclear structures, target materials are bombarded with high-energy particles. The target material can either be in a form of a metal film or gas. A target material designed to study certain ...
