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.

computer_simulation2An article by N.J. Laycock, D.P. Krouse, S.C. Hendy, and D.E. Williams published in the latest issue of Interface.

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.

Researchers from the University of Manchester in conjunction with the National University of Singapore have discovered an exciting new development with the wonder material graphene.

The researchers have been able to combine graphene with other one-atom thick materials to create the next generation of solar cells and optoelectronic devices.

With this, they have been able to demonstrate how multi-layered heterostructures in a three-dimensional stack can produce an exciting physical phenomenon exploring new electronic devices.

Ray Kurzweil – an author, computer scientists, inventor, futurist, and director of engineering at Google – has once been quoted saying, “In 25 years, a computer that’s the size fo your phone will be millions of times more powerful but will be the size of a blood cell.”

That prediction may be on its way to fruition with this new discovery from engineers in China and Australia.

The engineers have developed a double-walled carbon nanotube motor, which could be a huge player in future nanotechnology devices.

Students at the University of Wisconsin-Madison are not just interested in improving technology and creating innovative design, but rather they are determined to make us rethink the way the physical and digital world interact.

These students have spent months in the University’s Internet of Things Lab, where they work to measure, monitor and control the physical world by heightening its interaction with the Internet.

The main innovation that the lab has developed is a football helmet that can detect injuries.

Cross-disciplinary teams of students have come together to develop a high-tech football helmet that has brain wave probes and a device that measures acceleration forces, which gives the ability to detect concussions on the field and directly communicate the information to medical staff.
