Approach: The structure and composition of the modified GCE processed by using Carbon Nanotubes CNT and C60 to produce two modified electrodes CNT/GCE and C60/GCE, … …American Journal of Applied Sciences, Vol. 7, Issue 3 · 31 Mar 2010 · 7,492 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSynthesis of Coenzyme Q10Suryachandra Rao Ravada, Lakshma Reddy Emani, Machi Raju Garaga et al.Problem statement: CoQ10 is a key compound in ATP synthesis having wide number of health application especially for treating humans suffering from pathophysiological condition. The CoQ10 presently available in the market is solely derived from fermentation process. A commercially viable synthetic process is yet to be realized. Approach: The researchers described a new synthetic route for the preparation of CoQ10 … …American Journal of Infectious Diseases, Vol. 5, Issue 2 · 30 Jun 2009 · 9,010 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordInfluence of Heat Treatment in Sintering Process on Characteristics of Al2o3-Zro2 Ceramics SystemsA. Rittidech, T. TunkasiriAl2O3-ZrO2 ceramics containing 5-50 mol% ZrO2 were prepared by solid state reaction method. The bulk density, average grain size and microhardness of Al2O3-ZrO2 ceramics system as function of ZrO2 content were investigated. The dense Al2O3-ZrO2 ceramics were successfully by means of carefully control processing parameters that include sintering temperature and heating/cooling rates. These ceramics with higher ZrO2 content was obtained … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,012 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDistillation and Microdiffusion Modifications for total Nh4f Quantification and 15N RecoveryGaius D. Eudoxie, Gregory A. GouveiaProblem statement: Applying 15N techniques to accurately determine the fate of fixed ammonium (NH4f) in the strongly and weakly held pools require modifications to existing methodologies. Modifications are necessary for measurement of total NH4f in soils by direct digestion with 5 M HF: 1 M HCl, excluding alkali pretreatment, followed by distillation and quantification of NH4. Quantification by distillation was … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 4 · 31 Dec 2008 · 7,593 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDesalination of Saline Sludges Using Ion-Exchange Column with ZeoliteA.E. Ghaly, M. VermaA flushing process followed by a zeolite based ion-exchange process were developed for the treatment of saline sludges from oil and gas exploration sites. The particle size distribution of sludge sample indicated the presence of very fine sand and clay. The electrical conductivity of the sludge was 42.2 dS m-1 indicating very saline sludge and the Cation Exchange Capacity (CEC) … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 7,067 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMass Spectrometry/Mass Spectrometry Study on the Degradation of B-Aflatoxins in Maize with Aqueous Citric AcidA. Méndez-Albores, I. Nicolás-Vázquez, R. Miranda-Ruvalcaba, E. Moreno-MartÍnezDegradation of B-aflatoxins in maize by means of 1N aqueous citric acid was confirmed by the AFLATEST immunoaffinity column method, High Performance Liquid Chromatography (HPLC), tandem mass spectrometry (MS/MS) and computational information. The AFLATEST and HPLC assays showed that 96.7% degradation occurred in maize contaminated with 93 ng g-1 when treated with the aqueous citric acid.
