Research NotesOpen accessIn the abstractPolymerisation and Oxidation of Docosahexaenoic AcidBrian Mundell Ross, Shelly Lynn Browning, Adrian McKeeOils rich in polyunsaturated fatty acids, such as linseed oil, can oxidise to form polymers. These can be used as protective coatings and act as an alternative to those derived from petrochemicals. Such renewable source oils usually require the addition of metal ions as catalysts of the polymerisation process and/or the partial pre-oxidation of the oil before use. We hypothesised … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 1 · 11 Dec 2015 · 7,612 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis 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 accessIn the abstractCATION-EXCHANGE MEMBRANES WITH POLYANILINE SURFACE LAYER FOR WATER TREATMENTDinar Dilshatovich Fazullin, Gennady Vitalevich Mavrin, Michael Pavlovich SokolovIon-exchange membranes are widely used in modern technologies, particularly in the field of water treatment and make it possible to considerably reduce expenses for wastewater treatment and ensure high degree of purification. Currently, perfluorinated sulfated proton-conducting membranes are often used, such as NAFION and its Russian analogue, MF-4SK based on co-polymerization product of a perfluorinated vinyl ether with tetrafluoroethylene. However, … …American Journal of Environmental Sciences, Vol. 10, Issue 5 · 13 Sep 2014 · 7,403 accessesView PDFCite
Research ArticleOpen accessIn the abstractMechanism of Microencapsulation with Urea-Formaldehyde PolymerRochmadi, Agus Prasetya, Wahyu HasokowatiProblem statement: Microcapsule is one of important fine chemical products in the current chemical industries. Better understanding of microencapsulation process is useful to properly design of microcapsule with specific characteristics. The aim of this research is to study the mechanism of Urea-Formaldehyde (UF) microcapsules formation. Approach: Microcapsule was prepared in two steps. The first step was the preparation of oil … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 8,715 accessesView PDFCite

Research ArticleOpen accessIn the abstractPhysiochemical Properties of Sago Starch Modified by Acid Treatment in AlcoholP.H. Yiu, S.L. Loh, A. Rajan et al.Sago starch is usually chemically modified to overcome and improve the unstable properties of native sago starch during processing. In this study, sago starch was treated in hydrochloric acid in the presence of methanol, ethanol and 2-propanol at 450C for 1 hour. Granule size, granular structure and solubility of the modified starch were investigated. Results showed that recovery yields of … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 8,909 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermodynamic Profile of Some Heavy Metal Ions Adsorption Onto Biomaterial SurfacesMedhat A. ShakerThe adsorption of Co2+, Zn2+, Pb2+ and Hg2+ onto dried non-living biomass (NB) of different Pseudomonas strains has been investigated in detail. Maximum adsorption of these cations is achieved at optimum pH values from 3.5 to 4.5 to avoid hydrolysis, polymerization and precipitation of metal cations in the treatment solutions. The experimental data obtained at different temperatures were fitted to … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 6,877 accessesView PDFCite
Research ArticleOpen accessIn the abstractHydroxyapatite-induced Phagocytic Activity by Murine Macrophages in vitroV.K. Gopinath, M. Musa, A.R. Samsudin et al.The aim of the present study was to assess phagocytic activities of murine macrophages (RAW264.7 cell line) to hydroxyapatite (HA) particles. Transmission electron microscope (TEM) was used to assess localization of HA particles in the cells at 7, 15, 30 and 60 min. The HA particles and latex beads, as a control, were also incubated with the cells pretreated with … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 3 · 30 Sep 2006 · 6,370 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis, Characterization and Saponification of Poly (AN)-Starch Composites and Properties of their HydrogelsA. Hashem, M. A. Afifi, E. A. El-Alfy, A. HebeishHydrogels based on saponified products of poly (acrylonitrile, AN)-starch composites were prepared, characterized and their water abosrbency properties examined. The term composite refered to the resultant products of polymerizatin of AN with starch in presence of ceric ammonium nitrate (CAN) as initiator, that is the composite consists of poly(AN)-starch graft copolymer, homopoly(AN) , oxidized starch and unreacted starch. Thus AN … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 7,577 accessesView PDFCite
