Spring 2024 PhD Defenses: Yi He & Ishan Patel

Yi He and Ishan Patel are the latest ICMT PhD students to defend their dissertations.

Yi's research topic was, "Effect of Intermittent Wetting on Corrosion Inhibition in Oil/Water Systems". Understanding wetting phenomena is key to understanding corrosion itself, and how it can be mitigated. Stemming from her research, she has over 10 publications as conference proceedings papers and peer reviewed journal articles; including in CORROSION, Corrosion Science, and The Journal of the Electrochemical Society. Advised by Prof. Marc Singer, she performed her research within our corrosion inhibition focused project working with TotalEnergies. She is continuing research within ICMT.

Ishan Patel performed his research within ICMT's long-standing NAP-JIP, his dissertation work was on, "Modelling and Simulation of High Temperature Naphthenic Acid and Sulfidation Corrosion". He has manuscripts currently going through the peer review process, as well as several AMPP conference proceedings papers. He worked closely with NAP-JIP Project Leader Dr Gheorghe Bota, his advisor being Research Professor David Young. Ishan will be joining NETL as an ORISE post-doc.

Srdjan Nesic on the Knowns and Unknowns of CO2 Corrosion: February's CorroZoom Webinar

ICMT Center Director Srdjan Nesic will be presenting the next CorroZoom webinar on 20th February. Speaking on "Corrosion of Carbon Steel in Aqueous CO2 Environments - the Known Knowns and the Known Unknowns", he will present on the state-of-the-art on this topic, which is of key importance to the energy industries; from oil and gas production to carbon capture. Registration is required at Zoom

The abstract for his presentation reads as follows:

"The known knowns: gaseous CO2 is stable, mostly inert and non-corrosive. However, upon dissolution in water and a subsequent hydration, a more reactive chemical species - carbonic acid, is formed, which then partially dissociates to form an acidic solution, corrosive for carbon steel. Due to partial dissociation, these kinds of aqueous solutions are called weak acids, even if there is nothing weak about them when it comes to corrosion. Actually, aqueous CO2 solutions are more corrosive than strong acid solutions at the same pH. A lot is known about corrosion of carbon steel in aqueous CO2 solutions: the water speciation, the electrochemistry of cathodic and anodic reactions, the formation of protective layers, the most influential factors, etc. Over the past 50 years a vast body of knowledge was generated in this field, mostly driven by the challenges coming from the oil and gas industry, where the hydrocarbons that emerge from the ground are always accompanied with some CO2 and water, making internal corrosion of carbon steel facilities a large problem. Wells, pipelines, processing and distribution facilities are all affected.

The known unknowns: removal of anthropogenic CO2 from the atmosphere and its capture at the source is one of the largest scientific and engineering challenges facing humanity in the 21st century. If this CO2 is to be safely transported and stored underground, it must be compressed to pressures where it is in liquid or supercritical form. Even very small amounts of water, SOx and NOx (in the ppm range) can lead to catastrophically high internal corrosion rates of transportation and injection facilities made from carbon steel. Little is known about this type of corrosion and the understanding we have about aqueous CO2 corrosion of carbon steel does not carry over entirely."

Now in its 4th season, CorroZoom is a free webinar series administered by Prof. Gerald Frankel of The Ohio State University's Fontana Corrosion Center. Further information on CorroZoom, including webinar slides and recordings from past events, can be accessed at OSU.

Payman Sharifi Abdar Doctoral Defense

PhD student Payman Sharifi Abdar has successfully defended his dissertation research, "Mechanism and Modeling of Galvanic Corrosion between Mild Steel and Iron Sulfides in Acidic Solutions". Research within ICMT previously demonstrated that formation of different types of iron sulfides as corrosion products were a main culprit in localized attack, due to their wide-ranging physicochemical properties. Galvanic coupling between such iron sulfide layers and mild steel was suspected to be associated with the observed localized attack. The two types of iron sulfides investigated by Payman, pyrite and pyrrhotite, were shown to produce different galvanic corrosion due to their distinct electrochemical behaviors. To further elucidate the mechanism of the impact of iron sulfide type, the cathodic behavior of pyrite and pyrrhotite was systematically studied using a rotating disk electrode system. The results revealed that pyrrhotite has significantly higher cathodic current than pyrite. This difference originates from different cathodic reactions occurring at the surface of these iron sulfides. Manuscripts are in preparation relating to his findings. He has previously published in Electrochimica Acta and Analytical Methods. He has been a regular attendee at NACE and AMPP conferences, receiving 2nd place in the Mars Fontana Category for his research poster at CORROSION 2021. Payman's PhD advisor was University Distinguished Professor, and ICMT Director, Srdjan Nesic. He recently started a post-doctoral researcher position in the University of Pittsburgh's Department of Chemical & Petroleum Engineering, with an electrocatalysis research focus.



Post-defense, Payman with his committee members and project leaders.




Mohiedin Bagheri PhD Defense

ICMT PhD student Mohiedin Bagheri has successfully defended his dissertation research, "Mechanism of Anodic Dissolution of Iron and Steel in CO2 Environments". His research focus was the mechanistic investigation of the multistep reaction that occurs during CO2 corrosion. After critical review of the fundamental theories underpinning the oxidative dissolution reaction, he developed a simpler narrative that was successfully applied in corrosion modelling. Furthermore, has research yielded important insights into how specific environmental factors (e.g., pH, dissolved CO2, temperature, steel type, etc.) can mechanistically impact kinetics of elementary steps, and ultimately the overall reaction of iron dissolution. His advisor was Professor Srdjan Nesic, his committee members were Professor Howard Dewald, Associate Professor Katherine Cimatu, Associate Professor Marc Singer and Research Associate Professor Yoon-Seok Choi. Mohiedin holds a MS degree in Chemical Engineering, also from OHIO, as well as BSc and MSc degrees in Materials Science & Engineering from Sharif University of Technology. He has published in the peer reviewed journals Advanced Materials, Materials & Design, Journal of the Electrochemical Society, Materials Science & Engineering, Australian Journal of Chemistry, Electrochimica Acta, and Analytical Methods. He will be joining OLI as an Electrolyte/Corrosion Simulation Specialist.





Russ Outstanding Research Paper Award for 2022:
“Machine learning modelling of time-dependent corrosion rates of carbon steel in the presence of corrosion inhibitors”

M. Aghaaminiha, R. Mehrani, M. Colahan, B. Brown, M. Singer, S. Nesic, S. Vargas, and S. Sharma, Corrosion Science, 193 (2021)

The Russ Outstanding Research Paper Award recognizes excellence in research and scholarship exhibited by the faculty of Russ College and is awarded by recognition from a committee consisting of previous award recipients. (For more information click here.)
The team chosen for the award at the Institute for Corrosion and Multiphase Technology focused their efforts on modeling experimental data obtained from a series of experiments on corrosion inhibition of mild steel in CO2 saturated aqueous solutions. Regression analysis was performed using different ML algorithms (Artificial Neural Network, Random Forest, Support Vector Machines, and K Nearest Neighbors) to model experimental data of time-varying corrosion rates of mild steel specimens when corrosion inhibitors were added to the system in different concentrations and dose schedules and with and without pre-corrosion. One of the main conclusions was that the sensitivity of corrosion rates to changes in the environmental variables could be well-predicted by the trained RF model, which can eliminate the need to perform extensive experiments for different solution conditions in the lab. The paper can be found here.




ICMT Grad Student Recognition at OU’s EXPO 2023

Every Spring semester, Ohio University stages its Student Research and Creative Activity Expo. As usual, ICMT had multiple graduate students showcasing their research on the floor of our campus’s Convocation Center.

ICMT Duo Huiru Wang and Luntao Wang Publish Groundbreaking ToF-SIMS, XPS Manuscript

During their research at Université PSL and Sorbonne Université, recent ICMT PhD Huiru Wang and current post-doc Luntao Wang collaborated on a surface analysis investigation that is now published in Corrosion Science, "Adsorption mechanism of quaternary ammonium corrosion inhibitor on carbon steel surface using ToF-SIMS and XPS". In their groundbreaking work, they combined Time-of-flight secondary ion mass spectrometry (ToF-SIMS) and X-ray photoelectron spectroscopy (XPS) to characterize adsorption phenomena associated with the corrosion inhibitor molecule tetradecylbenzyldimethylammonium on a mild steel surface. They demonstrated that the adsorbed inhibitor surface coverage strongly depends on immersion time and inhibitor concentration, with a maximum as well as uniform coverage is found for sufficiently long exposure times at a critical inhibitor concentration of ca. 25 ppmw. The uniform adsorbed inhibitor layer formed on the surface was determined to mitigate the formation of iron chloride/hydroxide intermediates, thus enhancing the corrosion protection of carbon steel in aggressive environments. The manuscript can be accessed here: (ScienceDirect.com).
