Researcher seeks to understand corrosion

24.09.2008
A Binghamton University researcher hopes to shed light on why and how metals suffer corrosion, especially when under various types of stress.

Guangwen Zhou, an assistant professor in the Department of Mechanical Engineering, will use state-of-the-art techniques involving transmission electron microscopy, or TEM, to observe the oxidation process.

Oxidation is the loss of electrons by a molecule, atom or ion. One common example is the rust that results when a metal such as iron comes into contact with moist air.

Preventing rust and related damage is of vital interest to materials engineers as well as industry. An estimated 3 to 5 percent of the United States’ gross domestic product is spent on the repair of corrosion-related damage, Zhou said.

“This fundamental research can improve our understanding of metal oxidation on a nanometer scale,” he said. “This is increasingly critical as the dimensions of devices continue to shrink to nanoscale.”

The study, which will help in the search for substances that can protect the surface of metals, has implications for a number of fields, including thin film processing and fuel cells.

Zhou, whose work is supported by a new three-year, $250,000 National Science Foundation grant as well as a two-year, $50,000 grant from the American Chemical Society, will collaborate with Brookhaven National Laboratory and the University of Pittsburgh for the project.

He will apply stress to samples of copper and use in situ transmission electron microscopy to observe what happens on the nanoscale level when oxygen gas is introduced. Zhou said he has already begun training several graduate students in the unique microscopy techniques, which will allow researchers to visualize the reactions in real time.

About Guangwen Zhou:

Guangwen Zhou, who joined the Binghamton faculty in 2007, earned a doctorate in materials science at the University of Pittsburgh. He received a master’s in physics from Beijing University of Technology in Beijing, China, and a bachelor’s in physics from Xiangtan University in Xiangtan, China.

Zhou, who did post-doctoral research at Argonne National Laboratory, has published nearly 40 referred journal articles.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
