The solar global radiation and ambient air temperature data used in the system modeling belongs Phitsanulok province from 7 am-5 pm in the summer season. Approach: The system can be divided into two parts, i.e., … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 7,596 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhotocatalytic Activity and Antibacterial Behavior of Fe3+-Doped TiO2/SnO2 NanoparticlesLek Sikong, Budsabakorn Kongreong, Duangporn Kantachote, Weerawan SutthisripokProblem statement: Since bacteria mainly causes damage on fresh vegetables and fruits during transportation to market, anti-bacterial TiO2 photocatalyst was applied for their packaging films. However, it has been known that pure TiO2 exhibits low photocatalytic property due to rapid recombination of photo-activated electrons and holes. Doping with metal or metal oxide shows the improvement of photocatalytic activity and disinfection … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 15,233 accessesView PDFCite
Research ArticleOpen accessIn the abstractNoise Control Using Coconut Coir Fiber Sound Absorber with Porous Layer Backing and Perforated PanelRozli Zulkifli, Zulkarnain, Mohd Jailani Mohd NorProblem statement: Noise control was one of the major requirements to improve the living environment. One of the methods to do that is provided by sound absorber. Commonly, multi-layer sound absorbers are applied to absorb broadband noise that was composed of perforated plates, air space and porous material. However, multi-layers sound absorbers effectiveness depends on their construction. This study was … …American Journal of Applied Sciences, Vol. 7, Issue 2 · 28 Feb 2010 · 14,698 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Optimization of a 1.55 µm Waveguide Based on Silicon Planar Photonic CrystalsR. Bchir, A. Bardaoui, M. Machhout et al.Background: Silicon based Planar Photonic Crystals (PPC) are used for the design of a 1.55 µm waveguide. Line defects are then formed in the PPC structures, by removing rows of holes, to obtain a Planar Photonic Crystal Waveguide (PPCW). Objective: First, we varied the thickness of the Silicon slab and the pore radius in order to obtain optimum design parameters … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 7,472 accessesView PDFCite
