The electrical conductivity of coal, at either 1 kHz or d.c., was measured at 24Β°C on samples recovered from pyrolysis experiments aimed at modelling conditions during in situ gasification of coal. From an initial value of low3 S/m (when the coal is saturated with formation water), the conductivity

Polyaniline (PAn) was synthesized chemically and doped with various dopants, such as HCl, HCOOH, and methylene blue S), by an I 2 (C 16 H 18 ClN 3 immersion method. The structure of these samples was investigated by infrared (IR) spectroscopy and wide-angle X-ray di β raction (WAXD) analysis. Remarka
