Preparation and characterization of nanocrystalline TiO2 thin films

Abstract: Nanocrystalline anatase TiO 2 films have been prepared using sol–gel spin coating method. The sol has been prepared by mixing titanium isopropoxide with absolute ethanol and acetic acid at room temperature. The structural studies carried out revealed that the pristine films are amorphous in nature. The annealed films have been observed to be nanocrystalline in nature and the crystallinity has been observed to improve on annealing. The films are found to exhibit anatase phase with grain size of 19 nm and 22 nm for 450 °C and 550 °C annealed films. The high-resolution transmission electron microscope (HRTEM) image showed lattice fringes corresponding to the anatase phase of TiO 2 . The Raman spectra of the prepared films has been observed to be distinct without overlapping peaks suggesting that the prepared films have low level of impurity sites. The vibration peaks present in the spectra at 145 cm −1 , 394 cm −1 , 513 cm −1 and 635 cm −1 has been observed to unambiguously correspond to the Raman active modes of the anatase phase of TiO 2 .

Global views on integrating Six Sigma and ISO 9001 certification

Abstract: During the past three decades, ISO 9001 certifications have facilitated contemporary organisations to systematically achieve continual quality improvement. In the same period, Six Sigma has propelled organisations towards achieving zero defect manufacturing. Though these objectives are closely coinciding, the synergy of implementing ISO 9001 standard and Six Sigma has been eluding the contemporary organisations. This situation creates a need to globally view the development that has been occurring in the direction of integrating ISO 9001 certification and Six Sigma. This study reports a literature review conducted in this context. The result of this literature review indicated that, very little work on integrating Six Sigma and ISO 9001 standard has so far been carried out. Hence, it is concluded that the recent most version, namely ISO 9001:2008 standard is to be amended with the ideals of Six Sigma. In order to carry out this task, a roadmap is contributed in this paper.
