Brine treatment using natural adsorbents
(University of the Western Cape, 2011)
The current study investigated application of natural adsorbents in brine treatment. Brines are hypersaline waters generated in power stations and mining industries rich in Mg2+, K+, Ca2+, Na+, SO4 2- , Cl- and traces of ...
Synthesis of sulphonated and transition metal oxide doped polymeric nanocomposites for application in design of supercapacitors
(University of the Western Cape, 2011)
To meet a fast-growing market demand for next generation portable electronic devices with higher performance and increased device functionalities, efficient electrical energy devices with substantially higher energy, power ...
Highly selective mesoporous sorbents for mercury removal from industrial wastewater
(University of the Western Cape, 2011)
The results of this study show that novel mesoporous carbons were obtained as inverse replica of SBA-15, HMS and MCM-41 silica templates, with a large pore diameter (2-4 nm), a BET surface area of 1867, 874 and 910 m2g–1 ...
Synthesis and electrochemistry of novel conducting dendrimeric star copolymers on poly(propylene imine) dendrimer
(University of the Western Cape, 2011)
One of the most powerful aspects of conducting polymers is their ability to be nanostructured through innovative, synthetically manipulated, transformations, such as to tailor-make the polymers for specialized applications. ...
Brine treatment using natural adsorbents
(University of the Western Cape, 2011)
Studies involving the use of natural clays such as bentonite, montmorillonite and natural zeolite clinoptilolite in water treatment have been reported. Researchers suggested cost effective processes, such as ion-exchange ...
Impedimetric and electrode kinetic dynamics of DNA aptamer nanobiosensors for estrogeneous endocrine disruptors
(University of the Western Cape, 2011)
In this work, DNA aptamer biosensor systems were developed for the detection of l7p-estradiol - an estrogeneous endocrine disrupting chemical (EDC). Endocrine disrupting chemicals are group of compounds that impact negatively ...
Electro chemiluminescence and organic electronics of derivatised poly(aniline sulphonic acid) light-emitting diodes
(University of the Western Cape, 2011)
Electrochemiluminescence (EeL) is applied for industrial applications that have considerable potential, such as clinical diagnostic, analytical chemistry, and light-emitting devices, due to selectivity, sensitivity for ...
