Research ArticleOpen accessIn the abstractSynthesis and Characterization of Silver/Clay/Chitosan Bionanocomposites by UV-Irradiation MethodMansor Bin Ahmad, Kamyar Shameli, Majid Darroudi et al.Problem statement: Silver/Montmorillonite/Chitosan Bionanocomposites (Ag/MMT/Cts BNCs) have been synthesized by UV-irradiation reduction method in the absence of any reducing agent or heat treatment which is used to antibacterial application and medical devices. Approach: MMT, Chitosan and AgNO3 were used as a solid support, stabilizer and silver precursor, respectively. The properties of Ag/MMT/Cts BNCs were studied as a function of UV-irradiation … …American Journal of Applied Sciences, Vol. 6, Issue 12 · 31 Dec 2009 · 8,819 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis and Characterization of Silver/Clay Nanocomposites by Chemical Reduction MethodMansor Bin Ahmad, Kamyar Shameli, Majid Darroudi et al.Problem statement: Silver Nanoparticles (Ag-NPs) have been synthesized by using chemical reduction method into the interlayer space of a Montmorillonite (MMT) as a solid support which is used to antibacterial application and polymer nanocomposites for fabrication of medical devices. Approach: AgNO3 and NaBH4 were used as a silver precursor and reducing agent, respectively. The properties of Ag/MMT nanocomposites were studied … …American Journal of Applied Sciences, Vol. 6, Issue 11 · 30 Nov 2009 · 8,175 accessesView PDFCite
Research ArticleOpen accessIn the abstractRefractive Index and Fourier Transform Infrared Spectra of Virgin Coconut Oil and Virgin Olive OilW. Mahmood Mat Yunus, Yap Wing Fen, Lim Mei YeeThis study presents the refractive index and FTIR spectra of virgin coconut oil and virgin olive oil that have been measured in the wavelength range from 491.0-667.8 nm. The measurement of refractive index was carried out using a minimum deviation method while the IR transmission ranging from 600-4000 cm-1 was measured using FTIR spectrometer respectively. The measurements were done at … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 13,164 accessesView PDFCite
Research ArticleOpen accessIn the abstractPitch and Timbre Determination of the AngklungMohd Ridzuwary Mohd Zainal, Salina Abdul Samad, Aini Hussain, Che Husna AzhariThis research describes the pitch and timbre determination of the angklung, a musical instrument made entirely out of bamboo. An angklung has two main parts: the frame and the rattle tubes. The pitch of the rattle tubes can be determined using a formula that takes into consideration the length and diameter of the air resonator. This is compared with the … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 9,719 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Boron Carbonitride (BCN) Thin Films Deposited by Radiofrequency and Microwave Plasma Enhanced Chemical Vapor DepositionM.A. Mannan, M. Nagano, K. Shigezumi et al.Boron carbonitride (BCN) thin films with a thickness of ~4 µm were synthesized on Si (100) substrate by radiofrequency and microwave plasma enhanced chemical vapor deposition using trimethylamine borane [(CH3)3N.BH3)] as a molecular precursor. The microstructures of the films were evaluated using field emission scanning electron microscopy (FE-SEM) and X-ray diffractometry (XRD). Fourier transform infrared spectroscopy (FT-IR) and X-ray photoelectron … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 7,375 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Tactile Sensor for Detection of Skin Surface Morphology and its Application in Telemedicine SystemsRoozbeh Khodambashi, Siamak Najarian, Ali Tavakoli Golpaygani et al.We proposed a new type of tactile sensor that is capable of determining the surface morphology of skin lesions. The sensor consists of a brass cylinder with an axial bore. Three peripheral bobbins were machined in the cylinder around which three coils have been wound. An iron core can easily move inside the bore. One of the coils acts as … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 7,263 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Mixing on the Biological Degradation of Toluene under Aerobic ConditionsAbdel E. Ghaly, D.G. Rushton, K. MartinellThe effectiveness of in-vessel bioremediation in reducing the concentration of toluene in contaminated soil under continuous and intermittent mixing conditions using invessel composting system. The results showed that there was a startup period (60 h) during which the average temperature rose from 21 to 32 and 40°C (and then remained constant) for the bioreactors with continuous and intermittent mixing, respectively. … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 6,503 accessesView PDFCite
