Investigation of the inhibition effect of ibuprofen triazole against mild steel corrosion in an acidic environment

The inhibition performance of ibuprofen triazole (IT) on mild steel (MS) corrosion in 1.0 M HCl and 0.5 M H2SO4 has been investigated by using electrochemical (potentiodynamic polarization and electrochemical impedance spectroscopy), gravimetric, and quantum chemical studies. Electrochemical investigation indicates that IT hampers MS corrosion via adsorption through a mixed inhibition mechanism. The protection ability of IT increases with an increasing concentration of inhibitor and decreases with increasing temperature. The adsorption of IT molecules on MS surface follows the Langmuir adsorption isotherm. Certain quantum chemical parameters were calculated to ascertain the correlation between inhibitive effect and molecular structure of IT.

A reflection on the future of the quality management paradigm in the EU

In recent years, the Quality Management Paradigm has successfully taken root in the European Union’s business environment. Quality management besides being a multivariate issue including matters from management and economics till engineering may be called a global knowledge in permanent bubbling. This theoretical article is an eclectic effort to analyse the evolution of the Quality Management Paradigm. More specifically, the article deals with this management Paradigm evolution and change according to the present and future expected business environments.
