Nickel hydroxide nanostructures were synthesized by a hydrothermal reaction. The effect of different precursors and surfactants on the morphology of nickel hydroxide nanostructures was investigated. Nanostructures were characterized by X-ray diffraction, energy dispersive X-ray spectroscopy, scanning electron microscopy and Fourier transform infrared spectroscopy. The influence of Ni(OH)2 nano...
A crackand pinhole-free composite membrane consisting of an a-alumina support and a modified y-alumina top layer which is thermally stable up to 1100°C was prepared by the sol-gel method. The supported thermally stable top layer was made by dipcoating the support with a boehmite sol doped with lanthanum nitrate. The temperature effects on the microstructure of the (supported and unsupported) La...
The post-functionalization of poly(3-hexylthiophene) (P3HT) via various synthetic routes is reported. Well-defined and monofunctionalized ω-thiol-terminated P3HT, ω-carboxylic acid-terminated P3HT, ω-acrylate-terminated P3HT, and ω-methacrylate-terminated P3HT are obtained in high yields through a straightforward procedure. From those, different novel P3HT-based graft copolymers are synthesized...
