Biological utilization of bagasse, a lignocellulose waste

Author: Paterson-Jones, JC Date: 1989 The technology to produce ethanol and single cell protein from sugarcane bagasse has been developed. Hydrolysis of the hemicelluloses by dilute sulphuric acid produces a solution of xylose and other sugars and embrittles the cellulose/lignin ... Read more
Comparison between sucrose, ethanol and methanol as carbon and energy sources for biological sulphate reduction

Author: Greben, HA ; Maree, JP ; Mnqanqeni, S Date: 2000 Sulphate was reduced via sulphide to sulphur when operating a single-stage completely mixed reactor configuration feeding synthetic feed. The aim of this study was to determine the volumetric and specific sulphate reduction rates using sugar, ... Read more
Design of porous p-type LaCoO3 nanofibers with remarkable response and selectivity to ethanol at low operating temperature

Author: Shingange, Katekani ; Swart, HC ; Mhlongo, Gugu H Date: Apr 2020 This work reports on the fabrication of remarkably selective and sensitive LaCoO3 nanofibers (NFs) based sensors obtained after annealing at different temperatures of 550, 650, and 700 °C. Findings from field emission scanning electron and ... Read more

Electroformation of Pd-modified thin film electrocatalysts using E-ALD technique

Author: Mkhohlakali, AC ; Fuku, X ; Modibedi, Remegia M ; Khotseng, LE ; Mathe, Mkhulu K Date: Jul 2021 Electrochemical atomic layer deposition was used to form bimetallic (BiPd, CuPd) and trimetallic (CuBiPd) thin films via surface-confined reactions. Pd thin films were characterized by cyclic voltammetry, scanning electron microscopy (SEM) ... Read more
Genomic Resources

Author: Barros, E ; Morris, EJ Date: 2014 The fastest growing use of maize is for the production of fuel ethanol using the enzymatic conversion of corn starch to glucose and then to ethanol as well by converting the cellulosic (non-food) parts of maize to ethanol. However for the ... Read more
Options for suitable biofuel farming: Experience from Southern Africa

Author: Von Maltitz, Graham P Date: Apr 2017 Southern African countries’ interest in biofuel is due of its rural development potential. Finding models to optimize this benefit is therefore paramount. High-energy-density crops with low perishability allow farmers to grow small quantities ... Read more
Pd, PdSn, PdBi, and PdBiSn nanostructured thin films for the electro-oxidation of ethanol in alkaline media

Author: Xaba, Nqobile ; Modibedi, Remegia M ; Mathe, Mahlanyane K ; Khotseng, LE Date: Feb 2019 Pd, PdSn, PdBi and PdBiSn nanostructured thin films were prepared on Au substrate using the electrochemical atomic layer deposition technique. The activity of the nanostructured thin films towards the electro-oxidation of ethanol was tested ... Read more
Potential for sugarcane production under current and future climates in South Africa: Sugar and ethanol yields, and crop water use

Author: Singels, A ; Jones, MR ; Lumsden, Trevor G Date: Dec 2022 Spatial information on crop productivity and resource use is required to enable efficient sugarcane production with limited resources and under a changing climate. The objective of this study was to estimate biomass, sugar and ethanol yields ... Read more
Preparation and characterization of anode catalysts for the direct alcohol fuel cells (DAFC): methanol and ethanol

Author: Modibedi, Remegia M ; Masombuka, T ; Mohlala, M ; Mathe, Mahlanyane K Date: Nov 2007 The development of high performance electrode materials has been the key research objective in the field of direct alcohol fuel cells (DAFC) [1, 2, and 3]. A promising way to attain higher catalytic performance is to add a third element to ... Read more
Preparation, assay and certification of aqueous ethanol reference solutions

Author: Archer, M ; De Vos, BJ ; Visser, MS Date: Apr 2007 Internationally, certified ethanol reference materials are required to calibrate breathalysers and blood-alcohol measurement instruments. The CSIR National Metrology Laboratory of South Africa provides certified aqueous ethanol solutions with ... Read more
Synthesis and characterisation of binary electrocatalysts for electrochemical oxidation of ethanol in PEMFC

Author: Masombuka, T ; Modibedi, Remegia M ; Mathe, Mahlanyane K Date: Jun 2008 Ethanol is an alternative choice fuel for polymer electrolyte membrane fuel cells (PEMFC), due to its nontoxicity and its availability from biomass resources advocates its use in direct ethanol fuel cells. In this study PtSn/C and PtIr/C ... Read more
Treatment of acid and sulphate-rich effluents in an integrated biological/chemical process

Author: Maree, JP ; Greben, HA ; De Beer, Morris Date: Apr 2004 A novel chemical/biological process is described in which sulphate and sulphide are removed simultaneously during biological treatment. Partial sulphate removal is achieved during chemical pre-treatment. In the biological stage sulphate is ... Read more
