A novel, efficient, and ecocompatible electro copolymerization of anilines at platinum electrode using acetonitrile as non-aqueous solvent and lithiumperchlorate as supporting electrolyte was carried and described here. The progress and mechanistic study of copolymerization was done using cyclic voltammetry. The reaction proceeded smoothly and quantitatively at ambient temperature. © 2011 Wiley Periodicals, Inc.

An expression is found here for the small transverse displacement of a thin elliptic plate due to a force applied at an arbitrary point of the plate. The plate is in the form of a complete ellipse and is clamped along the boundary. The displacement is expressed in terms of infinite series in §§2–4. The convergence of the series is rapid unless the eccentricity of the ellipse is nearly unity. The simplest case in which the force is applied at the centre of the plate is considered in §5; the displacement of the centre due to this force is compared in §6 with the corresponding displacements of a circular plate and of an infinite strip.
