Research ArticleOpen accessEvery word in the titlePreparation of Porous Silicon P-Type and Thermal Diffusivity Measurement Using Photoacoustic TechniqueMohammed Jabbar Hussein, Suaad Sahib Hindal, Amany Akram AwaadPorous silicon (PSi) layers were formed on a p-type Si wafer. Electrochemical method was used to prepare 36 samples with three values of current density (10, 20 and 30) mA/cm2, each involved ( 20, 40, 60 and 80) min etching times the samples were heated to three selected temperatures of 100, 200 and 350°C in three groups. The first group … …International Journal of Structural Glass and Advanced Materials Research, Vol. 2, Issue 1 · 14 Nov 2018 · 7,437 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePhotoacoustic Measurement of Thermal Diffusivity of Polypyrrole Conducting Polymer Composite FilmsM. Y. Lim, W. Mahmood Mat Yunus, A. Kassim, H.N.M.E. MahmudThe thermal diffusivity has been measured for the Polypyrrole-Polyethylene Glycol (PPy-PEG) composite films by the open photoacoustic method. The experimental data were analyzed for thermal diffusivity by fitting procedure. The different process parameters such as different concentrations of insulating polymer, monomer and electrolyte and the different voltages used to prepare the PPy-PEG composite films brought changes in thermal diffusivity. The … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,692 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThermal Effusivity Measurement of Virgin Coconut Oil-Methanol Mixtures using Photoacoustic TechniqueFiras Kamel Mohamad Al-asfoor, W. Mahmood Mat Yunus, Azmi Zakaria et al.Thermal effusivity of virgin coconut oil-methanol mixtures were measured using open photoacoustic cell technique. The samples were prepared by simply mixing virgin coconut oil and methanol using similar procedure applied for preparation of biodisel. Thermal effusivity of the sample was obtained by fitting the experimental data of photoacoustic amplitude signal to the expression of photoacoustic signal as a function of … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2008 · 7,596 accessesView PDFCite

Research ArticleOpen accessIn the abstractStatic and Dynamic Mechanical Behavior of Hydroxyapatite-Polyacrylic Acid Composites Under Simulated Body FluidKalpana S. Katti, Phanikumar Turlapati, Devendra Verma et al.In this work, we have investigated mechanical response of hydroxyapatite/polyacrylic composites under dry, wet and simulated body fluid conditions. Hydroxyapatite (HAP) is mineralized under two conditions; one, in presence of polyacrylic acid (in situ HAP), second, in absence of polyacrylic acid (ex situ HAP). Further, in situ and ex situ HAP are mixed with polyacrylic acid to make HAP/PAAc composites. … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 2 · 30 Jun 2006 · 7,395 accessesView PDFCite
