Research ArticleOpen accessEvery word in the titleGraphene Synthesis by Plasma-Enhanced CVD Growth with EthanolTeresa Campo, María Cotto, Francisco Márquez et al.A modified route to synthesize graphene flakes is proposed using the Chemical Vapor Deposition (CVD) technique, by using copper substrates as supports. The carbon source used was ethanol, the synthesis temperature was 950°C and the pressure was controlled along the whole process. In this CVD synthesis process the incorporation of the carbon source was produced at low pressure and 950°C … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 27 Jul 2016 · 9,146 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSynthesis and Characterization of Ink (Carbon)-Perovskite/Polyaniline Ternary Composite Electrode for Sodium Chloride SeparationSavita Dixit, Sandhya PalWe reported the synthesis of ink-perovskite/Polyaniline composite electrode material for the separation of sodium chloride solution. These electrode materials are prepared by in situ polymerization process of aniline in the presence of perovskite ceramic material with carbon catalyst surface. This material is having the highest conductivity as a cathode material, environmentally benign and low cost material. The structure and morphological … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 2 Sep 2015 · 7,385 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlepH Mediated Control Synthesis of Lanthanide-Doped YPO4 Upconversion Nano/MicrocrystalsMeiling Tan, Shuwei Hao, Xiangbin Meng et al.A pH-mediated rational control over the phase transformation, morphology and size of lanthanide doped YPO4 nano/microcrystals has been accomplished using a hydrothermal route. The morphology of the resulting particles evolves from the spheres, to the nanoflakes and finally to the nanorods when increasing the pH value of the reaction solution from 1 to 9, while the induction of crystal phase … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 3 · 1 Jun 2015 · 7,933 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTotal Synthesis of Endangered Frog Alkaloid ’Epibatidine’, A Potent Analgesic of the FutureN.R. Dhatrak, M.G. Kulkarni’Epibatidine’ is a nicotinic alkaloid’, was first discovered in the skin of neotropical poisonous frog, ’Epipedobates tricolor’ found in Ecuador. John Daly in 1974 first isolated a trace quantity of this alkaloid by scarifying several frogs. With the evolution of NMR techniques the structure of this alkaloid was reported in 1992. An year after, Nobel Laureate Prof. E.J. Corey, devised … …Current Research in Drug Discovery, Vol. 1, Issue 2 · 26 Jan 2015 · 17,112 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSYNTHESIS AND CHARACTERIZATIONOF ORGANIC FUNCTIONALIZED MESOPOROUS SILICA AND EVALUATE THEIR ADSORPTIVE BEHAVIOR FOR REMOVAL OF METHYLENE BLUE FROM AQUEOUS SOLUTIONSameer H. Kareem, Inaam H. Ali, M. G. JalhoomThree Mesoporous Silica (MPS) with different functional groups were prepared by one-step synthesis based on the simultaneous hydrolysis and condensation of tetraethoxy silane with organo-silane in the presence of template surfactant Polydimethylsiloxane-Polyethyleneoxide (PDMS-PEO). The prepared materials were characterized by Fourier Transform Infrared Spectroscopy (FTIR), Thermogravimetric Analysis (TGA) and nitrogen adsorption-desorption experiments. The results indicate that the preparation of methyl and … …American Journal of Environmental Sciences, Vol. 10, Issue 1 · 28 Feb 2014 · 7,287 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIncorporation of Omega-3 Fatty Acid and Synthesis of their Metabolites in Muscle Tissue in Mice Fed with Flaxseed and Perilla-Enriched DietSheisa Cyleia Sargi, Flavia Braidotti Stevanato, Marcia Machado de Oliveira Dalalio et al.Polyunsaturated fatty acids omega 3 and omega 6 are believed to have beneficial physiological effects on the human body. The present study aimed to evaluate the incorporation and synthesis of omega-3 fatty acid and their metabolites in muscle tissue in mice fed with a flaxseed and perilla-enriched diet. The animals were fed a diet supplemented with flaxseed and perilla meals … …American Journal of Applied Sciences, Vol. 10, Issue 4 · 17 Apr 2013 · 7,013 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBiotransformation Using Recombinant Cmp Sialic Acid Synthetase and α-2, 6-Sialyltran Sferase: Enzymatic Synthesis of SialosidesUlrike Hubl, Cynthia Sun, Shuguang Zhang et al.In this research, we successfully expressed recombinant CMP-sialic Acid Synthetase (CSS) from Neisseria meningitides and 2,6-Sialyltransferase (SAT) from Photobacterium damsela in E. coli BL21(DE3) fermented at a scale of up to 8 litres using individual plasmids pIRL-1 and pIRL-4b, respectively.
