Currently, the U.S. market for polymer-coated and galvanized rebar in the construction industry is more than $4 billion per year. But research has shown that polymer coatings are not providing adequate corrosion protection for the rebar that helps to reinforce the nation’s aging infrastructure.
The Missouri S&T coating is an engineered mixture of glass, clays and water. A slurry is applied to the rebar and heated to more than 1,400 degrees Fahrenheit. The coating, which adheres to steel, promotes bonding with concrete and works to prevent corrosion from water and salt.
Missouri S&T has filed for a patent on the technology, which was developed by a team of researchers led by Dr. Richard Brow, Curators’ Professor of materials science and engineering, and Dr. Genda Chen, professor of civil, architectural and environmental engineering and interim director of the Center for Infrastructure Engineering Studies at S&T. The research was funded by the Leonard Wood Institute.
The Department of Defense has used related technology to develop blast-resistant walls. Brow and Chen realized that some ideas originally conceived by the U.S. Army Corps of Engineers could be built upon in order to engineer the glass-ceramic coating for rebar.
Missouri S&T recently licensed the new technology to Pro-Perma Engineered Coatings in St. Louis. “The goal is to take innovations like this out of the laboratory, team up with partners, solve problems, and make an economic impact,” says Keith Strassner, director of technology transfer and economic development at Missouri S&T.
Mike Koenigstein, who earned a bachelor’s degree in ceramic engineering at Missouri S&T in 1993, is managing partner of Pro-Perma. So far, he says, the company has two projects in the works that utilize the new coating. The first will involve the strengthening of marine structures in Corpus Christi, Texas. Next, Koenigstein plans to strengthen a sea wall near Pearl Harbor in Oahu. Both projects are sponsored by the Department of Defense.
In addition to protecting structures from water and salt, Brow and Chen say the new coating would help make bridges and buildings stronger in earthquake-prone regions.
According to Chen, there are approximately 800 short-span bridges in Missouri that need to be retrofitted or replaced. In addition, more than 200 longer-span bridges are in urgent need of rehabilitation.
Strassner and Koenigstein think the new rebar coating will prove to be in high demand. They envision opening a pilot plant dedicated to producing the glass-based coating in Rolla, which is already home to high-tech glass manufacturer Mo-Sci Corp. as well as Missouri S&T.
Pro-Perma and Mo-Sci are working as partners to commercialize the technology developed at Missouri S&T.
“We have all of the resources here to support technology-driven businesses,” Strassner says. “We want to be an economic engine for the state of Missouri.”

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
