Investigation of physical properties of mesoporous NANO-Ti02 for dye-solar

Mhlongo, Hlengiwe Gugu (2008)

The nanocrystalline dye sensitized solar cells, so called «Gratzel cells* are based on a wide band gap «3.0-3.2eV» semiconductor TiO2 in its nano-scaled form. These nano-sized TiO2 are sensitized by a dye monolayer so to ...
Measurement of the fusion barrier distribution for the 86Kr + 208Pb reaction

Ntshangase, Sifiso Senzo (2005)

The main object of this work is to investigate a method of determining the total capture cross-section without passing through separate measurements of quasi-fission, fusion-fission and evaporation residue, using the fact ...
Measurements of gamma-ray production cross sections of proton beam at energies of 66 to 125 MeV with calcium target

Kunyana, Ayanda (University of Zululand, 2018)

Cosmic rays are highly energetic charged particles not produced on Earth. Primary cosmic rays are composed mainly of protons, alpha particles and nuclei of many heavier elements. Secondary cosmic rays including neutrons, ...
Micro PIXE analyses of Furnace and Converter Mattes for the determination of trace element distribution and concentrations

Govender, Shaun (2006)

Analyses of the constituent matte phases by Particle Induced X-ray emission (PIXE) were performed to investigate the distribution and concentration of trace elements. These levels of sensitivity are beyond that of the ...
Nanostructured diamond-like carbon by dual pulsed laser ablation-pulsed gas feeding

Sibiya, Patrick Sipho (2007)

Diamond-like carbon films is a metastable form of carbon containing mixture of sp3 and sp2 hybridization. In the previous decades Diamond-like carbon has been studying widely due to its unique properties resembling those ...
Nuclear reaction analysis cross-sections measurements for Boron and Carbon.

Miya, Senzo Simo (2007)

The aim of the project was to measure nuclear reaction cross-sections for selected light elements such as Boron and Carbon for the database at Radiation Utilisation Group of Necsa. Deuteron-fnduced and "He-induced reactions ...
The O+ 1 -> O+ g monopole transition in 112Cd

Rohwer, Erich Gottfried (1985)

Internal conversion is a nuclear electromagnetic deexcitation process by which an electron is emitted from an atomic elec¬tron shell. This process competes with the emission of gam¬ma-rays from the nucleus- Recently ...
Optical determination of the temperature of a laser heated industrial diamond

Masina, Bathusiwe Nelisiwe (2008)

Diamond has the highest thermal conductivity among known materials. In order to heat diamond to high temperature and measure the temperature, one needs to have a laser heating system with sufficiently good power stability, ...
Phase formation sequence at metal-germanium interfaces in thin film systems.

Ndwandwe, O. Muzi (1996)

Germanium thin films are used in integrated circuit electronic devices. Interest in germanium is due to the high mobility of its electrons and holes. It can therefore be used among other things as a high speed complementary ...
Production of C, N and O fragments in the interaction of 12C with 12C at an incident energy of 200 MeV.

Dlamini, Mxolisi Justice (2006)

The double differential cross sections of different isotopes of carbon (C), nitrogen (N), and oxygen (0) emitted in the interaction of C with C at an incident energy of 200 MeV were measured in the angular range of 8- 45'. ...
Radiation shielding calculations by means of MCNPX

Lukhele, Mbongeni France (2006)

Monte Carlo radiation transport calculations were performed to re-evaluate the configuration of the horizontal target bombardment station of the ra-dionuclide production at iThemba LABS. Calculated neutron and photon dose ...
