(American Chemical Society, 2011-09)The objective of this study was to investigate the metabolite variations during industrial pasta processing (from semolina to dried pasta) for five different commercial products. Up to 76 metabolites were detected. Significant ...
-
(Springer Verlag, 2014-01)A metagenome expression library was created from Trinervitermes trinervoides termite hindgut symbionts and subsequently screened for feruloyl esterase (FAE) activities, resulting in seven recombinant fosmids conferring ...
-
(Elsevier, 2009-06)Novel hexabutylsulphonyltribenzotetraazachlorin–fullerene (C60) complexes of iron (FeHBSTBTAC–C60) and cobalt (CoHBSTBTAC–C60) have been synthesized and their electrochemistry and oxygen reduction reaction (ORR) compared ...
-
(2011-05)Dye solar cell (DSC) has become one of the attractive devices for the conversion of solar energy into electricity worldwide, because of their remarkable properties such as low cost, non-toxicity and easy to fabricate as ...
-
(ICFPAM, 2013-09)This study reports the successful synthesis and integration of metallo-octacarboxyphthalocyanines-multi-walled carbon nanotubes (MOCPc-MWCNTs) (M = Zn, Ga(OH) and Si(OH)2) hybrid system for the application of dye solar ...
-
(2011-11)This presentation investigates alternative photosensitisers used to enhance the performance and efficiency of dye solar cells. It looks at the synthesis, characterization and electrochemical evaluation of these dye solar cells.
-
(Elsevier, 2015-07)We report the chemical synthesis of various ZnO nanostructures and TiO2 nanoparticles and their dispersion in a P3HT matrix. The photoluminescence studies revealed improved charge transport in the active layer of the ...
-
(Springer, 2016-07)Metal oxides such as TiO(sub2), Li(sub4)Ti(sub5)O(sub12), SnO(sub2), SnO, M(sub2)SnO(sub4) (M=ZnM=Zn, Co, Mn, Mg), TMO (TM=MnTM=Mn, Fe, Co, Ni, or Cu), TM(sub3)O(sub4) (TM=CoTM=Co, Fe, or Mn), and lithium alloys Li–Sn, ...
-
(Wiley-VCH Verlag, 2009-07)Novel electrochemical sensors based on carbon paste impregnated with metallopthalocyanine (MPc, M¼Co, Fe) complexes, have been constructed for the assay of anti-HIV drug 2’,3’-dideoxyinosine (didanosine, DDI). Both modified ...
-
(2013-10)Ti6Al4V laser manufactured samples were analysed using optical and scanning electron microscopy equipped with X-ray micro-analyser. The presence of a, a(sub2), ß, a', and a'' phases were determined using differential ...
-
(2006-07)Motivation for the research: Interest exists in III-V semiconducting materials (InAs, GaSb, InSb and related alloys) for the detection of infrared radiation; Such materials could be used as alternatives for future infrared ...
-
(Elsevier, 2015-08)Over the past decade, hydrogen storage in metal-organic frameworks (MOFs) has received increasing attention worldwide because they possess versatile structures, high surface areas, large free volumes, ultrahigh porosities, ...
-
(American Chemical Society, 2005-12-09)The metathesis reaction is used as a key step for the synthesis of the indolo [2,3-a] carbazole core of rebeccamycin 13 and the sulfur analog of furostifoline 21. Using the same methodology for the attempted synthesis of ...
-
(BioMed Central, 2009-09)Community concern about asthma prompted an epidemiological study of children living near a petrochemical refinery in Cape Town, South Africa. Because of resource constraints and the complexity of refinery emissions, neither ...
-
(American Institude of Physics, 1997-03)Measured vertical profiles of temperature and wind an used to model infrasound propagation over a representative high savanna habitat typically occupied by the African elephant, Loxodonta Africana, to predict calling ...
-
(1997-08)This report reviews the state of knowledge on the occurrence, investigation, detection, monitoring, prevention and dispensation of methane layers in coal mines. Mining practice throughout the world in respect of methane ...
-
(1999-06)The primary aim of the project was to assess the current status of research on methane emission prediction for collieries in South Africa in comparison with methods used and advances achieved elsewhere in the world.
-
(2013-12)Electrochemical atomic layer deposition technique was chosen in this study for the deposition of platinum nanostructures onto various substrates such as carbon paper, nickel foam and titanium mesh. Electrochemical evaluation ...
-
(The European Fuel Cell Forum (EFCF), 2009-06)Pt-Ru-P was prepared by the chemical reduction method using sodium hypophoshite as a reducing agent on Vulcan XC 72 and multi-walled carbon nano-tubes (MWCNTs). Sodium citrate was added as the stabilizer during electro-catalyst ...
-
(Elsevier, 2014-11)Bimetallic Pt nanoparticles were prepared by alloying Pt with the non-noble transition metals, Co and Ni, using a conventional heat-treatment (HT) method and microwaveirradiation (MW). The resulting samples were PteCo-Ht, ...
