corrosion_blog_interfaceAn article by Kenji Amaya, Naoki Yoneya, and Yuki Onishi published in the latest issue of Interface.

Protecting structures from corrosion is one of the most important challenges in engineering. Cathodic protection using sacrificial anodes or impressing current from electrodes is applied to many marine structures. Prediction of the corrosion rates of structures and the design of cathodic protection systems have been traditionally based on past experience with a limited number of empirical formulae.

Recently, application of numerical methods such as the boundary element method (BEM) or finite element method (FEM) to corrosion problems has been studied intensively, and these methods have become powerful tools in the study of corrosion problems.

With the progress in numerical simulations, “Inverse Problems” have received a great deal of attention. The “Inverse Problem” is a research methodology pertaining to identifying unknown information from external or indirect observation utilizing a model of the system.

A new long-life aluminum-air battery is set to resolve challenges in rechargeable energy storage technology, thanks to ECS member Ryohei Mori.

Mori’s development has yielded a new type of aluminum-air battery, which is rechargeable by refilling with either salt or fresh water.

The research is detailed in an open access article in the Journal of The Electrochemical Society, where Mori explains how he modified the structure of the previous aluminum-air battery to ensure a longer battery life.

Theoretically, metal-air technology can have very high energy densities, which makes it a promising candidate for next-generation batteries that could enable such things as long-range battery-electric vehicles.

However, the long-standing barrier of anode corrosion and byproduct accumulation have halted these batteries from achieving their full potential. Dr. Mori’s recently published paper, “Addition of Ceramic Barriers to Aluminum-Air batteries to Suppress By-product Formation on Electrodes,” details how to combat this issue.

Stainless steels and other corrosion resistant alloys are generally protected from the environment by ultra-thin layers of surface oxides, also called passive films. Unfortunately, these films are not perfect and their Achilles’ heel is a propensity to catastrophic local breakdown, which leads to rapid corrosion of the metallic substructure. Aside from the safety and environmental hazards associated with these events, the economic impact is enormous.

In the oil and gas and petrochemical industries, it is of course usually possible to select from experience a corrosion-resistant alloy that will perform acceptably in a given service environment. This knowledge is to a large extent captured in industry or company-specific standards, such as Norsok M1.

However, these selections are typically very conservative because the limits tend to be driven by particular incidents or test results, rather than by fundamental understanding. Decision-making can be very challenging, especially in today’s mega-facilities, where the cost of production downtime is often staggeringly large. Thus significant practical benefits could be gained from reliable quantitative models for pitting corrosion of stainless steels. There have been several attempts to develop purely stochastic models of pitting corrosion.

“Modeling Volume Change due to Intercalation into Porous Electrodes”
Published in the Journal of The Electrochemical Society
Lithium-ion batteries are electrochemical devices whose performance is influenced by transport processes, electrochemical phenomena, mechanical stresses, and structural deformations. Many mathematical models already describe the electrochemical performance of these devices. Some models go further and account for changes in porosity of the composite electrode. Read the rest.

“The first meeting that I attended was held in Bridgeport, Connecticut, in 1928. I went with Dr. W. C. Moore, who had previously persuaded me to become a member. I knew immediately that I was interested in the Society. That interest was not due to the papers that I listened to. There was nothing strictly on electro-organic on the program. I believe that it was due to the enthusiasm of the group, and the fact that I was made to feel that I belonged.”
-Sherlock Swann, Jr.

An article by Richard Alkire in the latest issue of Interface.

Electro-organic chemistry had its champion in Sherlock Swann, Jr. His scholarship, especially his massive bibliographic efforts, served singlehandedly to keep alive the promise and spirit of electro-organic chemistry in the U.S. from the 1930s to the 50s.

He was a charter member of the Electro-organic Division of The Electrochemical Society, formed in 1940, and was the first person to hold the offices of Secretary, Vice-Chair, and Chair of that Division. Beginning with his first ECS meeting in 1928 and continuing throughout his life, he played an active role in the Society, including a term as President in 1958-59. He was the Electro-organic Divisional Editor of the Journal of The Electrochemical Society, 1939-59; the Lifetime Honorary Chair of the Chicago Section; and was made an Honorary Member of the Society in 1974.

Swann was born in 1900 in Baltimore, Maryland, where his family had deep roots and a tradition of service to society. His great-grandfather, Thomas Swann, served as governor of Maryland, as mayor of Baltimore, as President of the Baltimore & Ohio Railroad, and was a leading force in the creation of Druid Hill Park, Baltimore’s first large municipal park. His father served as Baltimore police commissioner and subsequently as Postmaster, and led the reconstruction of downtown Baltimore police commissioner and subsequently as Postmaster, and led the reconstruction of downtown Baltimore and its streets after the Great Fire of 1904.

As Larry Faulkner said, “Norman Hackerman has been one of those rare and valued great citizens who helps a large and complex society move from past to future.”

An article by Robert P. Frankenthal in the Summer 2008 issue of Interface.

Norman Hackerman, who died last year at the age of 95, was a giant among giants: a world renowned scientist, an outstanding educator, a highly successful administrator, and a champion for basic research. He was member of ECS for more than 60 years. His research focused on the electrochemistry of corrosion, its mechanism and the processes to prevent or inhibit corrosion. During the more than 50 years he served as an administrator, he continued as a research scientist and an educator, maintaining an active research group and teaching freshman classes. At the same time he served the government, ECS, and other technical societies in numerous capacities.

Marye Anne Fox, chancellor and distinguished professor of chemistry at the University of California, San Diego, summed up his contributions to the nation, as reported in Chemical & Engineering News, “More than any other American, Norman Hackerman’s strong support for investment in basic research was the dominant factor in American science policy over the past 50 years, including the years he served as chairman of the National Science Board.” She further states that as a leader, “his voice was a strong one for the highest ethical principles, imbued with rationality, even when this involved great personal cost.”
