Author:Perrie, BD; Strauss, PJ; Du Plessis, LDate:Aug 2007Ultra thin continuously reinforced concrete pavements (UTCRCP), in literature also referred to as Ultra Thin Reinforced High Performance Concrete (UTHRHPC), have been used in Europe successfully as a rehabilitation measure on steel bridge ...Read more
Author:Du Plessis, L; Kilian, A; Mngaza, KDate:Jul 2014The design and use of ultra-thin reinforced concrete pavements (UTRCP) are well known and are implemented successfully in residential streets and low-volume roads. Various publications are available to assist engineers and contractors to ...Read more
Author:Shingange, Katekani; Swart, H; Mhlongo, Gugu HDate:Nov 2019Herein, we report on one-dimensional porous Au-modified LaFeO3 nanobelts (NBs) with high surface area, which were synthesized through the electrospinning method. The incorporation and coverage of Au nanoparticles (NPs) on the surface of the ...Read more
Author:Ombinda-Lemboumba, Saturnin; du Plessis, A; Botha, LR; Rohwer, EG; Steenkamp, CMDate:Oct 2010The ultrafast dynamics of Zinc Phthalocyanine was studied using trasient absorption pump probe spectroscopy. Zinc Phthalocyanine was excited (pumped) at 672nm and probed by a white light continuum. The pump-probe technique used in this study ...Read more
Author:Kekana, PT; Sithole, Bishop B; Ramjugemath, D; Pillay, LDate:Jul 2014The main aim of this project is to develop a method that can effectively extract lignin from Kraft black liquors from South African mills in the form that would be suitable for valorisation into high value products. In this study the effects ...Read more
Author:Kekana, Petrus T; Sithole, Bishop B; Ramjugernath, DDate:Feb 2019Ultrafiltration of black liquor was studied in three different modules, namely, radial cross flow, rectangular cross flow and stirred cell over a wide range of operating conditions. Effects of different cut-off membranes on the permeate flux ...Read more
Author:Loveday, Philip W; Wood, DDate:Jan 2006A non-destructive examination procedure based on a guided wave inspection approach is used for the acoustic examination of glass fibre reinforced composite rods. This paper contains an investigation into the characteristics of guided wave ...Read more
Author:Munonde, Tshimangadzo S; Zheng, Haitao; Nomngongo, PNDate:Dec 2019The oxygen evolution reaction (OER) is an important reaction in water splitting. Nickel-iron layered double hydroxide (NiFe LDH) has been considered a potential catalyst for OER. Herein, we report a simple/green approach to improve the oxygen ...Read more
Author:Smit, MC; Ferreira, JA; Van Wyk, JD; Ehsani, MDate:Jan 1995The concept of an integrated structure for the capacitor, inductor and transformer of the series resonant converters presented. It is shown that the necessary capacitance can be achieved by using a bifilar primary and the leakage inductance ...Read more
Author:Jordaan, JP; Kruger, Carel P; Silva, B; Hancke, GPDate:Jul 2017Localization is important for a wide range of industries and applications. In underground mining, for instance, it is helpful to know the miners’ locations, particularly in emergency situations. One way this can be achieved is by using ...Read more
