Amenability of some Witbank bituminous ultra fine coals to binderless briquetting

Author: Mangena, SJ ; De Korte, GJ ; McCrindle, RI ; Morgan, DL Date: 15 Oct 2004 Five ultra fine bituminous coals from the Witbank coalfield were studied. Selected chemical and physical properties, coal petrographic characteristics and mineralogical compositions of the coals were measured. The coals were compacted, using ... Read more
Analysis of cobalt, tantalum, titanium, vanadium and chromium in tungsten carbide by inductively coupled plasma-optical emission spectrometry

Author: Archer, M ; McCrindle, RI ; Rohwer, ER Date: Dec 2003 Inductively coupled plasma optical emission spectroscopy (ICP-OES) was used to measure the concentrations of cobalt, tantalum, titanium, vanadium and chromium in solutions of tungsten carbide. The main advantage of the method described here ... Read more
The electrochemical effect of Al-doping on Li4Ti5O12 as anode material for lithium-ion batteries

Author: Ncube, NM ; Mhlongo, WT ; McCrindle, RI ; Zheng, Haitao Date: May 2018 This work investigates the electrochemical performance of Al-doped Li4Ti5O12 (LTO) on the Li site (Li4-xAlxTi5O12) and Ti site (Li4Ti5-xAlxO12) (x = 0.15), evaluated by galvanostatic charge-discharge tests and the electrochemical impedance ...

Highly effective removal of toxic Cr(VI) from wastewater using sulfuric acid-modified avocado seed

Author: Bhaumik, M ; Choi, HJ ; Seopela, MP ; McCrindle, RI ; Maity, Arjun Date: Jan 2014 Sulfuric acid modified avocado seed (ASSA), as a low-cost carbonized adsorbent, was investigated for the removal of toxic Cr(VI) from water/wastewater in batch experiments. A low temperature (100 °C) chemical carbonization treatment was ... Read more
Laser-induced breakdown spectroscopy for quantification of heavy metals in soils and sediments

Author: Ambushe, AA ; Du Plessis, A ; McCrindle, RI Date: Sep 2010 Laser-induced breakdown spectroscopy (LIBS) will be used to determine the contents of heavy metals in soils and sediments. LIBS results will be compared with the results obtained by inductively coupled plasma-optical emission spectrometry ... Read more
