Effect of carbon nanospheres on algal growth: the influence of physicochemical properties and environmental chemistry

Author: Nyembe, DW ; Musee, N ; Mamba, BB ; Mamba, V Date: Aug 2013 Algae (Pseudokirchnierella subcapitata) were exposed to pristine (p-) and oxidised (o-) forms of carbon nanospheres (CNSs) at concentrations of 0.1, 0.18, 0.32, 0.46 and 20 mg/L. At each concentration, the CNSs were sonicated for 1-h in three ... Read more
Electrocatalytic properties of prussian blue nanoparticles supported on poly(m-aminobenzenesulphonic acid)-functionalised single-walled carbon nanotubes towards the detection of dopamine

Author: Adekunle, AS ; Farah, AM ; Pillay, J ; Ozoemena, KI ; Mamba, BB ; Agboola, BO Date: Jun 2012 Edged plane pyrolytic graphite electrode (EPPGE) was modified with and without Prussian blue (PB) nanoparticles and polyaminobenzene sulphonated single-walled carbon nanotubes (SWCNTPABS) using the chemical deposition method. The electrodes ... Read more
Nitrite electrochemical sensor based on prussian blue/single-walled carbon nanotubes modified pyrolytic graphite electrode

Author: Adekunle, AS ; Mamba, BB ; Agboola, BO ; Ozoemena, KI Date: Sep 2011 Nitrite, NO2- (in neutral), and NO (in acidic media) were used as analytical probe to investigate the electrocatalytic properties of Prussian blue nanoparticles (PB) modified edge plane pyrolytic graphite (EPPG) electrode. Results indicate ... Read more
Supercapacitive properties of symmetry and the asymmetry two electrode coin type supercapacitor cells made from MWCNTS/nickel oxide nanocomposite

Author: Adekunle, AS ; Ozoemena, KI ; Mamba, BB ; Agboola, BO ; Oluwatobi, OS Date: Oct 2011 Supercapacitive properties of synthesised nickel oxides (NiO) nanoparticles integrated with multi-walled carbon nanotubes (MWCNT) in a two-electrode coin cell type supercapacitor were investigated. Successful formation of the MWCNT-NiO ... Read more
Towards HIV detection: Novel Poly(propylene imine) Dendrimer-Streptavidin platform for electrochemical DNA and gp120 aptamer biosensors

Author: John, SV ; Rotherham, LS ; Khati, M ; Mamba, BB ; Arotiba, OA Date: Jul 2014 The detection of sequence – specific DNA and HIV glycoprotein 120 (gp120) based on novel generation 4 poly(propylene imine) dendrimer/streptavidin platform is reported. The platform was prepared by the electrodeposition of the dendrimer on a ... Read more
The toxicity of oxidised DWCNTs to the aquatic organisms, and related causing mechanisms

Author: Lukhele, LP ; Musee, N ; Wepener, V ; Mamba, BB Date: Aug 2013 Carbon nanotubes (CNTs) find wide applications as their science and applicability are well understood. According to Lux Research Inc., the market for CNTs increased from $43 million in 2005 to $260 million by 2010. Whilst successful applications ... Read more
