    A novel method for coating surface polishing has been applied for a systematic study of the localized individual coating regions of the Al–Si coated steel. Polarization, EPMA and corrosion potential measurements have been applied for determination the ability of each region for protection of underlying steel. The susceptibility of the Si rich region, interface region and Fe-rich region to pitting corrosion decreases in the following order: Si-rich region>Fe-rich region>interface region. The elemental distribution of Si and Fe plays an important role in the corrosion behavior of coating film and influences its susceptibility to pitting process.

    We investigated the field-effect characteristics of mechanically stretched regio-regular poly(3-hexylthiophene) (P3HT) on a supporting poly(vinyl alcohol) (PVA) film. After stretching the P3HT/PVA film, large dichroism was observed in the polarized UV-Vis absorption spectra. The stretched P3HT films were applied parallel or orthogonal to the conduction channel of the transistor. The field-effect mobility was highly anisotropic, with larger mobility along the stretched direction of the films. The mobility increased with increasing stretch ratio (Sr) for the parallel devices but decreased for the orthogonal devices.
