Abstract

Please cite this article in press as: P.A. Prashanth, et al., Synthesis, characterizations, antibacterial and photoluminescence studies of solution combustion-derived ␣-Al 2 O 3 nanoparticles, J. Asian Ceram. Soc. (2015), http://dx. a b s t r a c tIn this work, we report a novel, economical, low temperature solution combustion synthesis (SCS) method to prepare ␣-Al 2 O 3 (Corundum) nanoparticles. Powder X-ray diffraction (PXRD), field emission scanning electron microscopy (FE-SEM), high-resolution transmission electron microscopy (HR-TEM), Fourier transform infrared spectroscopy (FT-IR), BET surface area and ultraviolet visible spectroscopy (UV-vis) measurements were used to characterize the product. Antibacterial studies were examined against gram −ve Klebsiella aerogenes, Escherichia coli, Pseudomonas desmolyticum and gram +ve Staphylococcus aureus bacteria by agar well diffusion method. The ␣-Al 2 O 3 nanoparticles showed substantial effect on all the four bacterial strains. Photoluminescence (PL) measurements under excitation at about 255 nm show that the alumina nanoparticles have emission peaks at 394 and 392 nm.

Nanoporous aluminum oxide membranes for biomedical micro hydraulic devices

“…In the FTIR spectra strong and weak transmittance peaks were observed at 3446 cm . The entire array of these peaks corresponds to the FTIR transmittance spectra of Al 2 O 3 [17], what confirms that nanoporous aluminium oxide membranes were formed.…”

Removal of malachite green from aqueous solution by magnetic CuFe2O4 nano-adsorbent synthesized by one pot solution combustion method

“…In this study, we make use of magnetic property of nano crystalline copper ferrite in the removal of dyes from effluents by adsorption as this property of ferrites is not much investigated. Adsorption property of ferrites depends on its structure and composition which in turn depends on the method of synthesis and the distribution of cations in the crystal lattice [20]. The diverse routes available or adopted to prepare nano-sized spinel ferrites are ball-milling, sol-gel, co-precipitation, hydrothermal etc.…”

Luminescence and spectroscopic investigations on Gd3+ doped ZnO nanophosphor

“…Realizing the fact that simplicity, time required for the synthesis and cost involved in the preparation are the key factors which decide its application in commercial scales search for new chemical route is very crucial. Considering these factors self-propagating combustion route offers best choice among other methods [3][4][5]. The advantage of this method is that the desired phase can be achieved with better control over stoichiometry with a relatively simple experimental setup.…”

“…The advantage of this method is that the desired phase can be achieved with better control over stoichiometry with a relatively simple experimental setup. The obtained product properties like crystal size, surface area, surface morphology, agglomeration can be tuned by the nature of fuel used for the combustion synthesis [5,6].…”
