The conversion of plant-derived omega-3 (n-3) -linolenic acid (ALA, 18:3n-3) to long-chain eicosapentaenoic acid (EPA, 20:5n-3) and docosahexaenoic acid (DHA, 22:6n-3) can enhance ALA sufficient diets in compare to ALA deficient diets. Alpha-linolenic acid (ALA) was extracted and enriched from flax seed oil. Commercial lipases Candida rugosa, Pseudomonas cepacea and P. fluorescens were used for transesterification of ALA enriched from flax seed oil into olive oil TAG back bone. Gas chromatography of olive oil showed it contained high amounts of oleic acid (C18:1, n-9), linoleic acid (C18:2, n-6) and palmitic acid (C18:0) with 0% of ALA. Among the commercial lipase C. rugosa has more preference to ALA and 27% of ALA was incorporated to TAG back bone of olive oil. In 24 hours reaction time, the ALA concentration in TAG of olive has increased to 26% while oleic acid decreased to 60% and palmitic acid decreased from 25 to 7%. The highest incorporation of ALA into olive oil (29%) occurred for ALA: olive oil mole ratio (1:2). There was a decline in incorporation of ALA in olive oil backbone with an increase in the amount of water. ALA incorporation of 25% occurred with 100 µl water while without water it was 27%; it decreased to 15% with 1 ml of water.","PeriodicalId":14591,"journal":{"name":"iranica journal of energy and environment","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73812449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Out of the choices available, X Selective Catalytic Reduction (SCR) has shown to be the most promising exhaust after-treatment system for reducing oxides of nitrogen in the near term in-use applications. SCRs use the ammonia containing compound urea, as a reducing agent. This paper describes an experimental investigation of Urea-SCR,which has been designed for comparing efficiency of the SCR system for diesel and biodiesel. For this study, a SCR exhaust system was tested on a steady state, direct injection Kirloskar single cylinder diesel engine. Mahua Methyl Ester (MME) oil has used as a biodiesel. From the experimentation, it was concluded that the conversion efficiencies were higher for diesel comparable to biodiesel. The analysis also shows the Urea SCR system has a maximum of 93.4% NO conversion efficiency of diesel fuel. For biodiesel, maximum NO conversion efficiency XX of Urea-SCR was approximately 49%. This experimentation also revealed that the Urea-SCR system hasan excellent HC conversion efficiency at all engine loads and using both fuels.","PeriodicalId":14591,"journal":{"name":"iranica journal of energy and environment","volume":"76 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76617728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The temperatures of source, substrate and the deposition time were optimized to deposit thin films of different thicknesses. Silver (Ag) was used as a dopant by ion exchange process in the ZnSe thin films. The structural analysis showed that as-deposited ZnSe thin films were polycrystalline having preferred orientation (111) direction. Micro structural parameters such as crystallite size, lattice parameter were determined using X-rays diffraction (XRD). Grains boundaries, roughness on surface and the grain density of the thin film samples were measured by scanning electron and atomic force microscopy before and after Ag doping.As-deposited, Ag-doped ZnSe samples before and after annealing were optically characterized by spectrophotometer in ultra violet, visible and infrared regions. The energy band gap of as-deposited ZnSe thin films for varying thicknesses were ranging from 2.62-2.67 eV which was reduced after Ag doping.The electrical properties showed that as-deposited thin films were highly resistive of the order of 10 -cm and after Ag immersion, it was reduced to 1 -cm.
