Abstract

In the present paper a method is developed for the determination of the orders of kinetics and activation energies of thermoluminescence (TL) glow curves recorded in a hyperbolic heating scheme. The suitability of the present method is tested by applying it both to numerically computed and experimental TL peaks. PACS No.: 78.60kn

Review on Mechanistic Action of Inhibitors on Steel Corrosion in Acidic Media

“…The adsorption of fig leaves follows Langmuir adsorption forming a layer of monomeric film, thereby protecting the steel from corrosion. Ambrish Singh et al [33] investigated Kalmegh plant leaves as corrosion inhibitor for steel. Kalmegh leaves extract contains oxygen atoms in functional groups (O-H, C=C, C=O, C-H, C-O) and aromatic ring, which meets the general consideration of typical corrosion inhibitors, as revealed by the FT-IR analysis.…”

Jump relations across a shock in non-ideal gas flow

“…, being the internal volume of the molecules, and therefore it is sufficient to consider the equation of state in the form (Anisimov and Spiner, 1972;Singh and Singh, 1998;Ojha, 2002) …”

“…Wu (1996, 2003) have used an equivalent equation of state to study the shock theory of sonoluminescence. The internal energy e per unit mass of the non-ideal gas is given by Singh and Singh (1998) and Ojha (2002), as…”
