Research ArticleOpen accessEvery word in the titleBIODEGRADABILITY AND MECHANICAL BEHAVIOUR OF SUGAR PALM STARCH BASED BIOPOLYMERJ. Sahari, S. M. Sapuan, E. S. Zainudin, M. A. MalequeA new Sugar Palm Starch (SPS) based biopolymer was successfully developed using glycerol as plasticizer. The effect of glycerol concentration (viz., 15, 20, 30 and 40 by weight percent) to the mechanical properties of plasticized SPS biopolymer was investigated. From this investigation, it was found that the 30% glycerol concentrated biopolymer showed the highest flexural strength and impact with the … …American Journal of Applied Sciences, Vol. 11, Issue 10 · 10 Nov 2014 · 7,704 accessesView PDFCite
Research ArticleOpen accessIn the keywordsApplication of the Ozonation Pre-treatment for Biodegradation of Aqueous Solutions of Methyltert-Butyl EtherM. Sadeghi, A. Mesdaghinia, A. Badkoubi et al.The effectiveness of ozone treatment for improving the biodegradability of recalcitrant pollutants has been proved by investigating the ozonation reaction of Methyl tert-butyl ether (MTBE) a bioresistant gasoline oxygenate. Laboratory scale experiments have been carried out, at room temperature, by bubbling, for 120 min, ozonated air (3.4 ppm min-1 ) into 3 liter of an alkaline (pH=11.5) aqueous solution (100 … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 6,463 accessesView PDFCite
Review ArticleOpen accessIn the abstractBio-Inspired Materials: Exhibited Characteristics and Integration Degree in Bio-Printing OperationsAntreas KantarosIn the last decade, additive manufacturing techniques, commonly known under the term "3d printing" have seen constantly increasing use in various scientific fields. The nature of these fabrication techniques that operate under a layer-by-layer material deposition principle features several de facto advantages, compared to traditional manufacturing techniques. These advantages range from the precise attribution of pre-designed complex shapes to the … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 4 · 29 Nov 2022 · 7,180 accessesView PDFCite
Research ArticleOpen accessIn the abstractLong-Term Characterization of Landfill Leachate: Impacts of the Tropical Climate on its CompositionJorge Luiz da Paixão Filho, Miriam Gonçalves MiguelThe disposal of Municipal Solid Waste (MSW) in sanitary landfills produces leachate, whose composition changes depending on the microbial community and the environmental conditions. However, these changes cannot be observed in sanitary landfill because of the superposition of cells, which makes it difficult to determinate the relationship among the phases of biodegradation of MSW, the composition of the leachate and … …American Journal of Environmental Sciences, Vol. 13, Issue 2 · 14 Mar 2017 · 8,573 accessesView PDFCite
Research ArticleOpen accessIn the abstractCHITOSAN NANOPARTICLES AND THEIR APPLICATIONS IN DRUG DELIVERY: A REVIEWSharare Najafi, Zahra Pazhouhnia, Omid Ahmadi et al.Chitosan is one of the most popular materials in the field of drug delivery due to its adhesivity and biodegradability. Different types of Chitosan based drug carriers have been conceived for various administration routes, such as oral, nasal, transdermal, parenteral, vaginal, cervical and rectal due to its biocompatibility and biodegradability. Chitosan Nanoparticles (NPs) have long been studied as carriers for … …Current Research in Drug Discovery, Vol. 1, Issue 1 · 8 Nov 2014 · 14,775 accessesView PDFCite
Research ArticleOpen accessIn the abstractCombustion, Performance and Emission Characteristics of Diesel Engine with Neem Oil Methyl Ester and its Diesel BlendsL. Prabhu, S. Sathish Kumar, M. Prabhahar, K. RajanBiodiesel, an alternative fuel is derived from the fats of animals and plants. As energy demands increase and fossil fuels are limited, research is directed towards alternative renewable fuels. The main advantages of using this alternative fuel are its renewability, biodegradability and better quality of exhaust gases. It is technically competitive and environmentally friendly alternative to conventional petro-diesel fuel for … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 7,259 accessesView PDFCite

In this study, the production of robust Chitosan nanoparticles has been developed and characterized by chemical crosslinking using sulfate anions. Approach: Chitosan polymer is considered one of the best … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 28 May 2012 · 9,871 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction of Biodiesel by Enzymatic Transesterification: ReviewA.E. Ghaly, D. Dave, M.S. Brooks, S. BudgeProblem Statement: The research on the production of biodiesel has increased significantly in recent years because of the need for an alternative fuel which endows with biodegradability, low toxicity and renewability. Plant oils, animal fats, microalgal oils and waste products such as animal rendering, fish processing waste and cooking oils have been employed as feedstocks for biodiesel production. In order … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 2 · 30 Jun 2010 · 21,467 accessesView PDFCite
Research ArticleOpen accessIn the abstractScreening Three Strains of Pseudomonas aeruginosa: Prediction of Biosurfactant-Producer StrainGholamreza Dehghan-Noudeh, Mohammad Hasan Moshafi, Effat Behravan et al.Problem statement: The chemical surfactants have some disadvantages; especially, toxicity and no biodegradability. Approach: Biosurfactants were the structurally diverse group of surface-active molecules synthesize by micro-organisms.
