Research ArticleOpen accessEvery word in the titleLiquid Crystalline Polymers Compatibilization and Adhesion Enhancement by Reactive Blending in Post-Consumers PET’sAversa Raffaella, Apicella AntonioA method for PET mechanical properties enhancement by reactive blending with HBA/HNA Liquid Crystalline Polymers for in situ highly fibrillar composites preparation is presented. LCP/PET blends were reactive extruded in presence of Pyromellitic Di-Anhydride (PMDA) and then characterized by Differential Scanning Calorimetry, Thermally Stimulated Currents and tensile mechanical properties. The formation of specific macromolecular structures, where the PET, the LCP … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 17 Jun 2016 · 8,186 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFactors Affecting Chemo-physical and Rheological Behaviour of Zr44-Ti11-Cu10-Ni10-Be25 Metal Glassy Alloy Supercooled LiquidsApicella Antonio, Aversa RaffaellaSegregation by selective cold crystallizations and glass transition changes in Zr44-Ti11-Cu10-Ni10-Be25 metal supercooled metastable liquid annealed at different temperatures have been theoretically correlated to melt viscosity modifications. Crystallization behavior has been found to be principally related to the high mobility and smaller Be, Cu and Ni atoms. Multiple exothermal peaks in isothermal DSC annealing’s have been observed in these bulk … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 25 Feb 2016 · 8,142 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of the Maximum Density Ratio Between Liquid and Vapor on Cavitating SimulationGuangjian Zhang, Weidong Shi, Ling Zhou, Desheng ZhangThe Filter-Based Model (FBM), which was built into CFX through CFX Expression Language (CEL) and a homogeneous cavitation model were employed to simulate cavitating flow around a 2D Clark-y hydrofoil. The effect of a maximum density ratio between liquid and vapor on sheet and cloud cavitating simulation was investigated. The results show that the maximum density ratio has a significant … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 21 Apr 2015 · 7,433 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Comparison of Spectrophotometric Method and High-Performance Liquid Chromatography in Photosynthetic Pigments AnalysisSabina Jodłowska, Adam LatałaProblem statement: Spectrophotometric method and High-Performance Liquid Chromatography (HPLC) are the most useful tools to photosynthetic pigments analysis. The main objective of this reaserch was to compere the results obtained by these two independent methods in experiments under controlled laboratory conditions. Approach: Comparison between spectrophotometric and HPLC methods for pigment analysis was carried out on Baltic cyanobacterium Geitlerinema amphibium, which … …OnLine Journal of Biological Sciences, Vol. 11, Issue 2 · 30 Sep 2011 · 10,865 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLaboratory Scale of Liquid Coal Fuel Combustion Process and Exhaust Gas FormationKartika Kus Hendratna, Osami Nishida, Hirotsugu Fujita, Wataru HaranoProblem statement: Much research of coal has been already undertaken to ascertain the possibilities of coal being used as substitute for heavy fuel oil in the transportation sector. The effects of using coal as transportation fuel to the environment must also be considered. This study will review several aspects of the coal oil combustion process including combustion behavior, flame stability, … …American Journal of Environmental Sciences, Vol. 6, Issue 3 · 30 Jun 2010 · 6,761 accessesView PDFCite
