Corrosion behaviour of WC-VC-Co hardmetals in acidic media

Author: Konadu, DS ; Van der Merwe, J ; Potgieter, JH ; Potgieter-Vermaak, S ; Machio, Christopher N Date: Sep 2010 The effect of increasing vanadium carbide (VC) content on the corrosion behaviour of tungsten carbide – 10 wt% cobalt hard metals was investigated in 1 M hydrochloric (HCl), and sulphuric (H2SO4) acids solutions. Increasing VC content makes ... Read more
Generating and measuring nondiffracting vector Bessel beams

Author: Dudley, Angela L ; Li, Y ; Mhlanga, T ; Escuti, M ; Forbes, A Date: Sep 2013 Nondiffracting vector Bessel beams are of considerable interest due to their nondiffracting nature and unique high-numerical-aperture focusing properties. Here we demonstrate their creation by a simple procedure requiring only a spatial light ... Read more
Modal decomposition for measuring the orbital angular momentum density of light

Author: Schulze, C ; Flamm, D ; Dudley, Angela L ; Forbes, A ; Duparr'e, M Date: Feb 2013 We present a novel technique to measure the orbital angular momentum (OAM) density of light. The technique is based on modal decomposition, enabling the complete reconstruction of optical fields, including the reconstruction of the beams ... Read more
Wavefront sensing with all-digital Stokes measurements

Author: Dudley, Angela L ; Milione, G ; Alfano, RR ; Forbes, A Date: 25 Sep 2014 A long-standing question in optics has been to efficiently measure the phase (or wavefront) of an optical field. This has led to numerous publications and commercial devices such as phase shift interferometry, wavefront reconstruction via ... Read more
