Research ArticleOpen accessIn the author namesPolysulfone Composed of Polyaniline Nanoparticles as Nanocomposite Proton Exchange Membrane in Microbial Fuel CellMansour Saleh Alhoshan, Manal Ismail, Javed Alam et al.Proton exchange membranes play a critical role in the performance of Microbial Fuel Cells (MFCs) but their high price was always a big deal for commercialization of MFCs. In the present study, doped and undoped polyaniline nanoparticles/polysulfone nanocomposites membranes as a new type of PEM, were fabricated and applied in the MFC and their performance was compared with Nafion 117 … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 4 · 25 Dec 2012 · 9,295 accessesView PDFCite
Research ArticleOpen accessIn the author namesAcetone Removal and Bioelectricity Generation in Dual Chamber Microbial Fuel CellMostafa Ghasemi, Mostafa Rahimnejad, Ghasem Najafpour et al.Synthetic waste water contain organic compound can be oxidized in an anaerobic conditions in microbial fuel cell while biodegradation of Chemical Oxygen Demand (COD) takes place under anaerobic condition in anode compartment. The microorganisms for biological treatment of the organic matter were obtained from a UASFB bioreactor. In the treatment of waste water, ones COD was removed the current and … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 4 · 25 Dec 2012 · 8,523 accessesView PDFCite
Research ArticleOpen accessIn the author namesCalibration Coefficients for Residual Stress Measurement in Composite Materials Using Finite Element MethodA. G. Ghasemi, M. AkbarzadehProblem statement: Since the residual stresses can cause a scienificant reduction in strength of the mechanical components, having a semi-destructive measuring method that would predict and model theses stresses would be an advantage. The hole drilling method has been used, by many researches, for measurement of the residual stresses in different materials. In this article, the finite element method is … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 1 · 18 Feb 2012 · 9,015 accessesView PDFCite
