New Pyrazine Derivatives as Efficient Inhibitors on Mild Steel Corrosion in Hydrochloric Medium
Chemical Engineering Transactions, 2016 Novel pyrazine derivatives PD-1 were synthesized and their inhibitive action against the corrosion of mild steel in 15% HCl solution was studied by weight loss, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) studies ...

Abstract and Applied Analysis, 2013 In this paper, conservation laws for the (2+1)-dimensional ANNV equation and KP-BBM equation with higher-order mixed derivatives are studied. Due to the existence of higher-order mixed derivatives, Ibragimov’s “new conservation theorem” cannot be applied

No Self-Interaction for Two-Column Massless Fields [PDF]
, 2004 We investigate the problem of introducing consistent self-couplings in free theories for mixed tensor gauge fields whose symmetry properties are characterized by Young diagrams made of two columns of arbitrary (but different) lengths.

Mitigation of corrosion of carbon steel in acid medium using some antipyrine derivatives
Zaštita Materijala, 2017 Adsorption and inhibition efficiency of some antipyrine derivatives on the C-steel (CS) in 1M HCl were estimated using three electrochemical techniques (electrochemical impedance spectroscopy (EIS), electrochemical frequency modulation (EFM) and ...

The combined viscous semi-classical limit for a quantum hydrodynamic system with barrier potential [PDF]
, 2014 We investigate the viscous model of quantum hydrodynamics, which describes the charge transport in a certain semiconductor. Quantum mechanical effects lead to third order derivatives, turning the stationary system into an elliptic system of mixed order ...

International Journal of Electrochemical Science, 2012 The focus of this study is to synthesize new calixarene derivatives namely calix[8]arenes (3a) (P1) and (2a) (P2), and to test its performance as corrosion inhibitor of steel in molar HCl at 308K. Polarization and weight loss measurements were used.
