Application of corrosion inhibitors for steels in acidic media for the oil and gas industry: A review

An academic scientist’s professional success depends on publishing. Publishing norms emphasize novel, positive results. As such, disciplinary incentives encourage design, analysis, and reporting decisions that elicit positive results and ignore negative results. Prior reports demonstrate how these incentives inflate the rate of false effects in published science. When incentives favor novelty over replication, false results persist in the literature unchallenged, reducing efficiency in knowledge accumulation. Previous suggestions to address this problem are unlikely to be effective. For example, a journal of negative results publishes otherwise unpublishable reports. This enshrines the low status of the journal and its content. The persistence of false findings can be meliorated with strategies that make the fundamental but abstract accuracy motive – getting it right – competitive with the more tangible and concrete incentive – getting it published. We develop strategies for improving scientific practices and knowledge accumulation that account for ordinary human motivations and self-serving biases.

Scientific Utopia: II - Restructuring Incentives and Practices to Promote Truth Over Publishability

Metal–organic frameworks (MOFs) have received huge attention in the last years as promising porous materials with unrivalled degree of tunability for a wide range of applications including gas storage or separation, catalysis, drug delivery and imaging. The present review appraises the application of MOFs in the field of electrochemistry. From materials for rechargeable batteries, supercapacitors and fuel cells to electrocatalysis or corrosion inhibition, MOFs or MOF-derived materials are gaining momentum in this field. For real breakthroughs, combining their electrochemical properties with appropriate electronic and ionic conductivity will be required.

The inhibition of benzimidazole derivatives on corrosion of iron in 1 M HCl solutions

4-aminoantipyrine (AAP) was tested as a corrosion inhibitor for mild steel in 2 M HCl solution using different techniques: weight loss, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). The results showed that AAP is an inhibitor for mild steel in this medium. The inhibition was assumed to occur via adsorption of the inhibitor molecule on the metal surface. In the 20 to 60 ∘C temperature range, the AAP adsorption follows the Flory–Huggins isotherm and/or the El-Awady et al. kinetic-thermodynamic model. The protection efficiency increases with increasing inhibitor concentration (in the range 10−310−2 M) but decreases with increasing temperature. The thermodynamic functions of dissolution and adsorption processes were calculated.
