Author:Salehiyan, Reza; Bandyopadhyay, Jayita; Ray, Suprakas SDate:May 2019In this study, polyamide 6 (PA) is blended with ethylene vinyl alcohol (EVOH) to yield packaging materials with a balance of mechanical and gas barrier properties. However, the formation of gel-like structures in both polymers because of ...Read more
Author:De Beer, Morris; Maina, J; Van Rensburg, Yvette; Fisher, ColinDate:May 2018Mechanistic design and construction of flexible pavements with relatively thin (< 50 mm) asphalt road surfacings still remain an art today and are aimed especially towards first-class user experiences. Risks for surfacing failures are difficult ...Read more
Author:Cummings, FR; Le Roux, Lukas J; Hietkamp, SDate:Jul 2008Titanium dioxide (TiO) nanotubes hold great potential for application in dye-sensitised solar cells for they provide a one-dimensional transport route for generated charge carriers. An investigation is launched into the formation of these ...Read more
Author:Skosana, PJ; Van Vuuren, DS; Heydenrych, MDDate:May 2015A mechanistic model describing the mass and momentum exchange in bubble columns is proposed that is based on the observations that the gas distribution in a bubble column is not uniform across the column and that as a consequence large liquid ...Read more
Author:De Beer, Morris; Maina, JW; Netterberg, FDate:Apr 2012This paper (Part 2 of a two-part set of papers) discusses models and illustrates the adverse effects of weak layers, interlayers, laminations and/or weak interfaces in flexible and semi-flexible pavements, also incorporating lightly cemented ...Read more
