The impact of brand equity on brand preference and purchase intentions in the service industries

Abstract: The antecedents of brand equity are considered to be brand attitude and brand image, and the consequences of brand equity are considered to be brand preference and purchase intentions. This study concentrates on service brands, selecting 18 from 3 service categories. A structural equation model is presented. Not only does it show a good fit with the research constructs but also the relationships between brand image and brand equity, and brand attitude and brand equity. The impact of brand equity on customer preference and purchase intentions is confirmed as well, which tends to validate the proposed research framework.

Hydrothermal Synthesis of Single-Crystalline Anatase TiO2 Nanorods with Nanotubes as the Precursor

Abstract: Preparation of anatase TiO2 nanorods from solutions in the absence of surfactants or templates has rarely been reported. The present work has found that hydrothermal treatment of titanate nanotube suspensions under an acidic environment resulted in the formation of single-crystalline anatase nanorods with a specific crystal-elongation direction. The nanotube suspensions were prepared by treatment of TiO2 in NaOH, followed by mixing with HNO3 to different pH values. The crystal size of the anatase nanoparticles obtained from the hydrothermal treatment increased with the pH of the suspensions, and nanorods with an aspect ratio up to 6 and a long axis along the anatase [001] were obtained at a pH slightly less than 7. A mechanism for the tube-to-rod transformation has been proposed on the basis of the crystalline structures of the tubes and rods. The local shrinkage of the tube walls to form anatase crystallites and the subsequent oriented attachment of the crystallites have been suggested to be the key step...
