Faculty and staff recipients of the university's most distinguished awards will be honored Wednesday, Oct. 2, in the Memorial Union Sun Room. The awards ceremony begins at 3:30 p.m., followed by a reception.

Ames Laboratory staff will receive the following awards:

Louis Thompson Distinguished Undergraduate Teaching Award

Established by the late Louis Thompson, emeritus associate dean of Agriculture and Life Sciences, the award recognizes an outstanding teacher who is dedicated to helping undergraduate students. A $1,500 award is granted.

  • Alan RussellImage
    Professor of materials science and engineering
    Numbers don't always tell the whole story, but in the case of Russell's teaching quality, they do provide some insight. Over the last six years, Russell's teaching evaluations by students have averaged 4.8 on a 5-point scale. That's for all of his classes -- small and large; introductory and advanced. At no time in his 37-year career here has he received an evaluation lower than 4.2.




  • Patricia ThielImage
    Distinguished Professor in Liberal Arts and Sciences and professor of chemistry
    Thiel's teaching ability is best described by one of her students: "Dr. Thiel was great. She is clever in how she presents material and tries to relate concepts to things that are easier to understand. Her corny jokes were fun, too. ISU really needs to find more teachers like her."

Ames Laboratory is taking advantage of Titan, one of the world’s most powerful computers, to discover substitutes for rare-earth magnets. In the race to find substitutes, supercomputers are the lead-off runner, ensuring that scientists can rapidly target the best possibilities for materials discovery. Titan, located at the DOE’s Oak Ridge National Laboratory in Oak Ridge, Tenn., uses a combination of traditional central processing units and graphics processing units that were first created for computer gaming.

ImageU.S. Department of Energy (DOE) Ames Laboratory’s scientists Bruce Harmon, Kai-Ming Ho, and Cai-Zhuang Wang use the enormous capability of supercomputing to identify promising compositions of new magnetic materials that do not contain rare earth elements, elements that are increasingly in short supply. Stronger non-rare earth permanent magnets are critical to replace the current rare earth magnets for energy efficient electric drive motors (used in hybrid and electric vehicles) and more powerful electrical generators (used in wind turbines).

Harmon, Ho, and Wang are using a highly efficient genetic algorithm (GA) developed in the 1990s at the Ames Laboratory by Ho and David Deaven to search the enormous phase space of stable crystal structures and compositions.

It’s a very visual model that looks at possible compositions in terms of “parents” splitting and joining to produce “offspring,” with each successive generation being evaluated and selected to optimize specific traits, explained Harmon.

 “Back in the ‘90s it would take 65,000 iterations to get a result using this algorithm, and that would take several months. But paired with increased abilities in supercomputing, this algorithm has been the foundation for what we’re trying to do in solids right now. It’s powerful, and it works,” said Harmon.

Titan’s capabilities offer scientists the tools to complete computational research work in mere hours, said Wang.

“To get the new materials we are looking for with the right magnetic properties, we are most likely looking at ternary structures with a larger number of atoms. This is a much more complex problem, and very difficult to explore,” said Wang. “The increased computer capabilities paired with an efficient algorithm will open up new areas for us to search for new alloys.”

Harmon believes supercomputing will be useful in reducing the need for both the painstaking experimental work and often sheer luck involved in finding a useful magnetic material in the huge number of yet undiscovered ones.

“For thousands of years, humans have discovered useful alloys through hit-or-miss metallurgy,” said Harmon. “Now, we finally have the computing capability to explore greater complexities using quantum mechanics-- greater numbers of atoms, the possible crystal structures, and their properties. We can determine which will be optimal, hand it to experimentalists, and say ‘this alloy composition may have a ‘sweet spot’ with ideal properties.’ In turn, experimentalists can return to us and say, ‘this did not work, but maybe the addition of this other element can help.’”

In this way, Harmon said, theorists and experimentalists will be able to work closely together to speed the discovery process for alternatives to rare earth alloys.

The computer time was granted through the DOE’s Innovative and Novel Computational Impact on Theory and Experiment (INCITE) program, which promotes scientific discoveries and technological innovations by awarding time on supercomputers annually on a competitive basis. A total of 61 projects, including the Ames Laboratory’s, were granted computer time for 2013.

The computational search for the crystal structures and new materials for permanent magnet applications is supported by the Beyond Rare Earth Materials project, led by Iver Anderson at the Ames Laboratory and funded by the DOE’s Energy Efficiency and Renewable Energy (EERE) Office, Vehicle Technology Program. The basic science, algorithms, and computational code development for the structure prediction and phase diagram exploration is supported by the Exploratory Development of Theoretical Methods project funded by Materials Science and Engineering Division of Basic Energy Sciences, U.S. Department of Energy Office of Science through the Ames Laboratory.

The Ames Laboratory is a U.S. Department of Energy Office of Science national laboratory operated by Iowa State University. The Ames Laboratory creates innovative materials, technologies and energy solutions. We use our expertise, unique capabilities and interdisciplinary collaborations to solve global problems.

DOE’s Office of Science is the single largest supporter of basic research in the physical sciences in the United States, and is working to address some of the most pressing challenges of our time. For more information, please visit

ImageThe Ames Laboratory Employee Commuting (ALEC) program is ready for the 2014 fiscal year which starts Oct. 1. ALEC is a web-based program that allows Ames Lab employees to automatically provide data on their daily commute. That data will be used to help the Lab meet the 13% decrease in its greenhouse gases by 2020 per the DOE’s Sustainability Goal and Executive Order 13423 —Strengthening Federal Environmental, Energy, and Transportation Management.

“The DOE has mandated that we decrease our carbon footprint,” said Ames Lab interim director Tom Lograsso. “While there are a number of things we’re doing at the Lab to address that goal, employee commuting is one more piece of the puzzle. Knowing how far employees commute each day helps us establish a base line and ALEC will give us some actual data to work with … and a research lab is all about getting good data! I would encourage employees to check the program out and help both the Lab and the environment.”

The program allows you to set up your primary means of commuting as your default. So if you travel most often by car, you can enter the roundtrip miles, the make of your vehicle and an estimate of its miles/gallon. Then, if you ride your bike, take the bus, walk or don't commute at all for a particular day, you can edit the information for that day by clicking on that date in the calendar and change only that day while leaving your default information intact.

The current ALEC program has been revised based on employee comments and suggestions after trying out the original “beta” version. A tutorial has been added to help you get started. To access ALEC, go to; a link to the tutorial is located in the navigation bar along the top and at the far right.

If you successfully logged on previously, please check that your information is still current. Those who have not attempted or attempted and were unsuccessful due to software issues, please try again, since this data is important to achieve the Lab’s goals. Note that no information is directly attached to any employees’ names for final fiscal year calculations. Only the Ames Laboratory totals for each category are utilized and submitted in the DOE report. If you have questions or comments, please email

ImageKarl A. Gschneidner Jr., Ames Lab senior metallurgist, has been named the winner of the 2014 Acta Materialia Materials and Society Award. The award honors scientists who have made a major positive impact on society through materials science.

Gschneidner, known as “Mr. Rare Earth,” is considered the world’s foremost authority on the science of rare earths, a group of elements that are necessary ingredients in clean-energy technologies, including electric-drive car motors, and direct-drive wind turbines; personal electronics, such as color televisions, computers, cell phones, and sound systems; and military applications.

Through his long scientific career and expert testimony before Congress in 2010 and 2011, Gschneidner has been instrumental in bringing attention to the importance of rare earths for the nation’s energy and security future. Earlier this year, Gschneidner was named the chief scientist for the Critical Materials Institute, a $120 million DOE Energy Innovation Hub led by Ames Laboratory that will find innovative technology solutions to help avoid a supply shortage that would threaten the U.S. clean energy industry and security interests.

Gschneidner is also the co-discoverer, with Ames Laboratory scientist Vitalij Pecharsky, of the giant magnetocaloric effect in a gadolinium-silicon-germanium alloy, which can be used to create magnetic cooling devices. These devices will offer significant energy and environmental benefits as they begin to replace conventional refrigeration technology.

Gschneidner, who is also an Anson Marston Distinguished Professor of materials science and engineering at Iowa State University, started his career at Ames Laboratory and Iowa State University in 1952-1957 as a graduate student. After working at Los Alamos National Laboratory, he returned to Ames Laboratory and Iowa State University in 1963. In 1966, Gschneidner established the Rare Earth Information Center and was its director for 30 years. He’s published a series of handbooks on rare earths, with volume 44 currently in press. Gschneidner has published more than 510 scientific journal articles, 173 book chapters, conference proceedings and reports, and 204 phase diagram evaluations. He holds 15 patents (with four more pending) and has given 324 invited talks.

Among many other honors, Gschneidner was elected to the National Academy of Engineering in 2007, received the Acta Materialia Gold Medal in 2008, and the Frank H. Spedding Award (named for Gschneidner’s mentor and the first director of Ames Laboratory) from the Rare Earth Research Conferences in 1991.

“Karl has been an outstanding member of the Ames Laboratory and Iowa State University research community. His enthusiasm for the rare earths is contagious and he is an inspiration to his colleagues and students,” said Thomas Lograsso, Ames Laboratory Interim Director. “Many of the technological advances we enjoy today are based on Karl’s work or work of his well trained students.”

Gschneidner was selected for the Materials and Society Award by an international panel of judges appointed by the Acta Materialia board of governors. Acta Materialia will present the award to Gschneidner at the TMS meeting in February 2014.

The U.S. Department of Energy (DOE), the Ames Laboratory, and Iowa State University marked their newest endeavor in intensive energy research with the official opening of the Critical Materials Institute on Tuesday, Sept. 10.

With the Critical Materials Institute, its fifth Energy Innovation Hub, the DOE launches a concentrated effort to develop solutions to domestic shortages of rare-earth metals and other materials vital to U.S. energy security. These materials are essential in many modern clean-energy technologies – such as wind turbines, solar panels, electric vehicles, and energy-efficient lighting.

“A robust and innovative clean-energy sector creates new jobs, helps strengthen our economy, and ensures a cleaner and safer planet for our children,” said David Danielson, Assistant Secretary for Energy Efficiency and Renewable Energy. “The global clean energy race is not something we can afford to lose. America must continue to make significant investments in clean-energy technologies and the Department of Energy is leaving no stone unturned in our all-of-the-above approach to solving the nation’s energy challenges.”

DOE announced in January that the Ames Laboratory had been selected to lead the Critical Materials Institute with federal funding of up to

$120 million over five years. The Hub is a collaboration of leading researchers from universities, four DOE national laboratories, and members of industry.

“Drawing from our historical strength in rare earth chemistry, metallurgical expertise, and analytical capabilities, the Critical Materials Institute will carry on the research tradition that has been the hallmark of the Ames Laboratory,” said Ames Laboratory Interim Director Tom Lograsso.

Iowa State University President Steven Leath said the university and federal partnership has historically led to “incredible advancements” in fuels, new materials, and environmental sustainability, and would continue to do so.

“We’re extremely proud that the Ames Laboratory and Iowa State University were selected by the Department of Energy to lead its newest hub here,” said Leath. “We’re ready to tackle the challenges in ensuring that this nation, its industries and government, have a safe, stable and reliable supply of critical materials.”

Alex King, director of the Critical Materials Institute, invited Karl A. Gschneidner, Jr. chief scientist for the CMI and senior metallurgist for the Ames Laboratory, to cut the ribbon to the CMI offices in a newly renovated wing of Wilhelm Hall on the Iowa State University campus.

“This is not the end of anything,” said King. “This is actually just the beginning. Now we get to cut the ribbon, and we go to work.”

Energy Innovation Hubs are major integrated research centers with researchers from many different institutions and technical backgrounds that combine basic and applied research with engineering to accelerate scientific discovery in critical energy areas. The CMI is the fifth hub to be launched by DOE.
