Argonne News

Argonne researchers have discovered new information on the behavior of nano-engineered platinum surfaces — information that may bring polymer electrolyte membrane fuel cells for hydrogen-powered vehicles another step closer to full development.

Two Argonne researchers, Nenad Markovic and Vojislav Stamenkovic (both MSD), in collaboration with colleagues Philip Ross and Bongjin Mun at Lawrence Berkeley National Laboratory, Christopher Lucas from the University of Liverpool and Guofeng Wang from the University of South Carolina, have recently discovered that the nanosegregated platinum-nickel alloy surface has unique catalytic properties, opening up important new directions for the development of active and stable practical cathode catalysts in fuel cells. The results are published in the journal Science.

Rather than use a trial-and-error approach, Stamenkovic and Markovic examined platinum-nickel single crystal alloy surfaces with state-of-the-art surface-sensitive probes. The mechanism of action has been attributed to specific properties at the atomic and molecular level of the surface.

The research identified the platinum-nickel alloy surface as displaying an unusual electronic structure and arrangement of surface atoms in the near-surface region. This structure enhanced activity of the platinum catalysts by several orders of magnitude, resulting in the highest activity ever observed on a cathode catalyst. The platinum-nickel alloy configuration inhibits oxide formation, breaking the oxygen bond on active platinum sites.

According to Stamenkovic, “This discovery sets a new bar for catalytic activity in fuel cells and makes it feasible to meet U.S. Department of Energy targets for platinum-specific power densities without a loss in cell voltage.

“We have identified a cathode surface that is capable of achieving and even exceeding the target for catalytic activity, with improved stability for the cathodic reaction in fuel cells,” said Stamenkovic. “Although the platinum-nickel alloy itself is well known, we were able to control and tune key parameters, which enabled us to make this discovery. Our study demonstrates the potential of new analytical tools for characterizing nanoscale surfaces in order to fine-tune their properties in a desired direction.”

In these fuel cells, the main fuel is hydrogen which, through its reaction with oxygen, produces water as its only product.

“Although there are signs that in the near future these fuel cells may become the modern equivalent of the Carnot cycle engine,” Markovic said, “in order to make hydrogen-based energy systems a vibrant and competitive force, many problems still need to be solved.

“First,” he said, “at practical operating current densities, the significant over potential for the oxygen reduction reaction reduces the thermal efficiency well below its thermodynamic limits. Second, an approximately five-fold reduction of the amount of platinum-loading in current fuel cell stacks is needed to meet cost requirements for large-scale automotive applications. Finally, the dissolution or loss of platinum surface area in the cathode must be greatly reduced. To overcome these limitations and to make hydrogen viable as a renewable energy source, a breakthrough in catalyst research was needed.”

George Crabtree, director of Argonne's Materials Science Division, emphasized the path-breaking importance of the research. “This dramatic increase,” he said, “addresses one of the grand challenges of the hydrogen economy: reducing the amount of expensive platinum catalyst needed to operate fuel cells efficiently. It is not only world-class basic science, it is a major advance for energy research.”

The next step will be to build and analyze a conceptual and structural “bridge” between the single crystal system and working electrocatalysts. To achieve this, the researchers will try to create nanostructures that preserve the most technologically interesting characteristic of the platinum-nickel alloy single crystal system.

To meet this goal, Markovic and Stamenkovic have recently moved from Lawrence Berkeley National Laboratory to Argonne, where they expect to do research well beyond the present frontier of electrocatlysis. The unique activity of nanosegregated platinum-nickel alloy catalysts will be the foundation for the new research program at Argonne. The program will build on the electrochemical and electrocatalytic strengths already existing at Argonne in the research of materials scientist Hoydoo You.

Three new laboratories, equipped with the-state-of-the-art ex-situ and in-situ surface sensitive probes, spectroscopes and electrochemical techniques will provide new environment to resume the critical work in electrocatalysis.

The project will also use major facilities at Argonne, including the Advanced Photon Source, the Center for Nanoscale Materials, the Electron Microscopy Center and a strong interaction with theory.

The techniques and concepts derived from this program are expected to make overarching contributions to other areas of science well beyond the focus on electrocatalysis. “We hope that this program will lead the nation to more secure energy independence and a cleaner environment for future generations,” Markovic said.

This research was funded by DOE's Office of Basic Energy Sciences and by General Motors.

Three young scientists with promising careers ahead of them have been appointed postdoctoral fellows at Argonne.

Jana Zaumseil has been appointed the 2007 Ugo Fano Postdoctoral Fellow. She will conduct research at Argonne's Center for Nanoscale Materials. She comes from the Cavendish Laboratory at the University of Cambridge, United Kingdom. Her research there has focused on ambipolar transport in polymer semiconductors and light-emitting polymer field-effect transistors.

Ross Young has been appointed the 2007 Eugene P. Wigner Postdoctoral Fellow. He will pursue his research in Argonne's Physics Division. He comes to Argonne from the Thomas Jefferson National Accelerator Facility. A major focus of his research has been lattice-QCD-related hadron-physics.

Gregory Halder has been appointed the 2007 Arthur Holly Compton Postdoctoral Fellow. He will conduct research in Argonne's Materials Science Division. He comes to Argonne from the University of Sydney, Australia, where his work has focused on polynuclear spin-crossover molecular switches.

“The 2007 fellows display superb ability in their fields,” said Argonne Director Robert Rosner. “I'm confident that combining their talent with Argonne's world class facilities and staff will generate exciting new directions for research and will launch them on to distinguished careers.”

The fellowships are named after scientific and technical luminaries who have been associated with Argonne, its predecessors and The University of Chicago since the 1940s. Fellowships are competitively selected and are awarded for a two-year term, with possible renewal for a third year.

“Attracting and retaining the best and brightest young scientific talent is the goal of the Postdoctoral Fellow Program at Argonne, and to help us better achieve that goal, we have recently reorganized and expanded our postdoctoral programs,” said Harold Myron, director of Argonne's Division of Educational Programs.

The overall program comprises three separate postdoctoral opportunities: The Argonne Named Postdoctoral Fellowships, the Director's Postdoctoral Fellowships and Division Postdoctoral Appointments. They will be overseen by the newly created Argonne Postdoctoral Committee.

Al Sattelberger, associate laboratory director for physical sciences, which oversees Argonne's Educational Programs, said he believes reorganizing the programs under one oversight group will help insure the quality of the programs and will help Argonne be competitive in attracting talented young scientists and engineers.

Strengthening the postdoctoral programs is part of the laboratory's talent initiative, which strives to further develop the quality of Argonne's science and operations staff to meet research and development challenges of the future. “The ultimate goal of the initiative,” Sattelberger said, “is to develop a systematic approach for attracting, developing and retaining personnel, as well as a thoughtful approach to educating the next generation of scientists and engineers.”

“It may be something of a cliché to say that an organization's most important asset is its people, but in the case of Argonne, it's true,” said Rosner. “We want to be the best in the world at what we do — innovative research and development in the national interest, focusing on some of the hardest scientific and technical problems facing our nation. To succeed we must attract, develop and retain world-class and diverse personnel.”

The impact of satellite observations on scientific understanding of the early universe will be the topic of the 2007 Enrico Fermi Lecture in Physics, to be held at Argonne Tuesday, Feb. 27.

University of Chicago professor Stephan Meyer will present “Results from the Wilkinson Microwave Anisotropy Probe (WMAP)” at 2 p.m. in the Building 402 Conference Center. All employees whose schedules permit are invited to attend.

Meyer, from the university's departments of Astronomy and Astrophysics, and Physics, is deputy director of the Enrico Fermi Institute, and associate director of the Kavli Institute for Cosmological Physics.

Meyer's talk will focus on the WMAP satellite, designed to make definitive full-sky maps of the cosmic microwave background at large angular scales. The resulting measurements, along with those of other experiments, have helped in the development of a robust model of the evolution of the universe from its first seconds through 100,000 years. The model is based on known nuclear physics, thermodynamics and weak gravity, but it also requires new speculative components like Dark Matter and Dark Energy, and speculative ideas like an early era of inflation. Meyer will discuss the early universe model, WMAP instruments and measurements, and how they come together to impact cosmology.

Some older computer systems and hardware devices may be confused when daylight-saving time begins Sunday, March 11, instead of the first Sunday in April.

The 2005 Energy Policy Act, which goes into effect this year, changes the dates of both the start and end of daylight-saving time (DST).

Most modern computer systems and applications have been patched to take these changes into account and should not have a problem negotiating the new DST changes. Older, unsupported systems and some hardware devices may not.

Owners of computer and microprocessor-based systems and applications critical for time, business, safety or operations should be aware of the impending changes and assess the compliance of their systems and potential impact.

More detail, including a matrix of known systems and their compliance status, can be found online. CIS personnel are available to assist laboratory staff in assessing the compliance of their systems. Contact the CIS HelpDesk at help@anl.gov or ext. 2-9999 to request assistance.

Gilbert J. Perlow, a noted physicist and a leader in Argonne's Physics Division for many years, died Feb. 17 in Downers Grove at age 91.

Perlow was born in New York City in 1916, received his B.A. from Cornell in 1936 and a Ph.D. in physics from The University of Chicago in 1940. He married the late Mina Rea Jones, a Ph.D. chemist, before leaving Chicago. The two collaborated both in life and often on forefront research projects.

During World War II, Perlow worked at the Naval Ordinance Laboratory and then at the Naval Research Laboratory on underwater submarine detection. Later he carried out some of the first experiments on radiation in space using captured German V-2 rockets.

He became a staff member at Argonne in 1953. He was a pioneer in utilizing the Mössbauer effect to determine the internal magnetic fields of iron atoms and substances such as the newly created compounds of the noble gas xenon. He was frequently sought out as a distinguished visitor by noted international laboratories. Perlow's intense interest in the practical applications of science led him to become the editor for two decades of the Journal of Applied Physics and of Applied Physics Letters, two major physics journals in the United States.

Perlow retired from Argonne in 1986, but he retained his sheer delight in science and joy in learning how things work and remained active. He was also an avid sailor and commodore of the Chicago Corinthian Yacht Club.

All employees are welcome to join the Argonne Exercise Club, which meets Monday through Friday in Building 200, Room K131.

The Exercise Club is an organization dedicated to the fitness lifestyle. According to the American Heart Association, every hour of regular exercise increases life expectancy by two hours.

The Argonne Hispanic-Latino Club (HLC) has begun publishing a monthly newsletter to inform the Argonne community about club news items and upcoming activities.

The club hosts activities that promote cultural awareness and support the lab and surrounding communities with such activities as a student education day, annual Hispanic Heritage Month events and an end-of-year toy drive. The club is open to all interested employees.

Registration deadline is Thursday, March 1. For more information, see the meeting Web page or call contact Heidi Hartman at ext. 2-6487.

‘Green' remodeling project in Building 202 wins award

George Norek (FMS-ENG) and Keith Trychta (BIO) have won a Pollution Prevention and Environmental Stewardship Award for their efforts in the remodeling of the QA wing in Building 202.

Four executive orders direct the federal government to reduce the environmental impact of its operations. These “greening the government executive orders” are designed to demonstrate leadership in environmental excellence and use the purchasing power of the federal government to stimulate markets for new products and services that will help other businesses reduce their environmental impact.

The DOE's Office of Science honored Norek and Trychta for pollution prevention in the design and conversion of old storage space into office space. This award recognizes work that protects the environment in sustainable design and green buildings, while saving money and resources.

Due to a shortage of office space, the objective of the remodeling in Building 202 was to incorporate sustainable design and green building criteria into the design and construction of the QA wing. Originally a rodent breeding facility, the QA wing had very long and narrow rooms which were able to be used only as a storage facility for the last 15 years. By transforming the storage space into offices, laboratory space originally proposed for offices will continue to be used as much-needed laboratories.

The green remodeling project included using as much of the existing structures as possible, recycling material such as metals, wiring and light bulbs, installing additional wall insulation, using drywall made of recycled materials, installing high-efficiency windows, using paint and carpet that do not emit volatile organic compounds and contain an anti-microbial additive, using furniture made of recycled materials, and improving the heating and cooling system to increase energy efficiency. As a result of this renovation, almost $4,000 a year is expected to be saved in heating and cooling costs and more than 71,000 pounds of carbon dioxide emissions will be eliminated annually.

“Good design includes understanding the end users' needs and providing them with effective and efficient work space,” said Norek, FMS Architect and Project Manager. “Good design also requires that Facilities Management Services (FMS) engineers design a safe, cost effective, environmentally friendly work environment while utilizing unique or high-end design elements that inspire Argonne employees. This is achieved by utilizing creative design and responsible product selection and is one of the most cost-effective strategies to reduce energy consumption and cost of operations. Every dollar saved in facility costs can be directed toward science, assuring good stewardship of public funds and resources.”

The project has also been nominated for the prestigious White House “Closing the Circle” Award. “This project will set a precedent for other remodeling projects at Argonne,” said Gregg Kulma, Pollution Prevention/Waste Minimization Project Coordinator. The finished space provides open office space for 15 employees as well as a conference area.

“It's great to have more usable work space without having to sacrifice laboratory space,” said Trychta, Building 202 Manager. “Connie Ashbaugh of Project Management and Engineering (PME) made a huge impact on the color scheme, furniture design, carpet selection and window shades for this project. The renovation turned an ugly storage space into space that people enjoy working in. I believe this space will become one of the more desirable work environments here at Argonne.”

Norek and Trychta will receive their certificate of appreciation in April.

DOE solicits nominations every December for projects in sustainable design/green buildings, environmental management systems, waste pollution/prevention and electronics stewardship and recycling. Nominations for projects in any of these categories can be sent to Kulma at gkulma@anl.gov.

New division will focus on leadership-class computing

A Leadership Computing Facility Division has been established at Argonne to advance the computational sciences and the leadership-class computational capabilities required for today's frontiers of scientific discovery.

The newly created LCF Division will operate the Argonne Leadership Computing Facility as part of a federal effort to provide leadership-class computing resources to the U.S. Department of Energy scientific community to spur breakthrough science. The first system installed, an IBM Blue Gene/L with 2,048 processors, is actively used to support investigations in key applications in such areas as protein structure prediction, computational spectroscopy, fracture in disordered media, climate modeling and aircraft combustor simulation. The LCF plans to deploy a 100 teraflop/second Blue Gene system in 2007, followed by a larger system in 2008-09.

Raymond Bair has been named head of the LCF. Bair, who holds a Ph.D. from Caltech, joined Argonne in 2003 as a senior computational scientist and has served as leader of Argonne's Laboratory Computing Resource Center and as science coordinator for TeraGrid. He is currently a senior fellow of The University of Chicago/Argonne Computation Institute.

The LCF will be part of Argonne's Computing and Life Sciences directorate.

Srajer to lead XOR, named XSD associate division director

George Srajer has been named the next leader of X-ray Operations and Research (XOR), and the associate director of the X-ray Science Division (XSD), at Argonne 's Advanced Photon Source.

Srajer has been at the APS since its earliest days, participating in the construction of the first beam lines on the experimental floor. He led the successful development of magnetic X-ray scattering at Sector 4, brought in a diverse and illustrious community of researchers in nanomagnetism and recently published a comprehensive review of research in magnetic materials — as well as a preview of future opportunities — in this rich field of physics.

In recognition of his leadership and the deeper understanding of magnetic interactions that he has brought to the field, Srajer received The University of Chicago Distinguished Performance Award in 2003. For the past nine months, he has served with distinction as acting associate division director.

Use paved, cleared walkways to avoid hidden hazards

Employees can prevent unnecessary injuries by using snow-free, cleared walkways when accessing their vehicles and buildings on site.

Over the past year, several injuries have been attributed to employees taking shortcuts through uncleared areas when accessing their personal vehicles or when entering or exiting buildings. Although it is common for individuals to take the shortest route possible, especially in frigid weather or if pressed for time, hidden hazards may cause injury.

Some recent incidents that resulted in U.S. Occupational Safety and Health Administration-recordable injuries at Argonne include:

• Using an embankment to access a vehicle, which resulted in a strained back from a slip and fall

• Tripping over a lawn sprinkler head, which resulted in a fractured finger and chin abrasion

• Cutting across the lawn to access a building instead of using the sidewalk, which resulted in facial abrasions from tripping in a snow-covered hole.

Some common slip, trip and fall hazards that may be encountered on site include divots and rocks in open lawns or fields, raised tree roots in forested areas, uneven sidewalk sections, slippery embankments and utilities obstructed by brush overgrowth.

Employees and contractors should always use paved and cleared walkways and immediately report any potentially hazardous ground conditions to management.

‘Magic Fuel' and RERTR Program topic of March 7 APS Colloquium

Armando Travelli (NE) will present “The Hunt for a Magic Fuel: A Historical Perspective of the RERTR Program and a Glimpse into Its Future” at an Advanced Photon Source Colloquium Wednesday, March 7.

The talk will begin at 3 p.m. in the Building 402 Auditorium. The monthly APS colloquiums are open to all on site.

The U.S. Department of Energy initiated the Reduced Enrichment for Research and Test Reactors (RERTR) program in 1978, in response to increasing concern about the potential diversion of highly enriched uranium (HEU) for use in nuclear weapons. The program's primary objective is to develop the technology needed to minimize and eventually eliminate use of HEU in civilian applications worldwide.

Travelli will outline the successes and failures of the RERTR program along the many bumps of this road – technical and otherwise – the future challenges to the program's objectives, and what could be done to improve the chances that HEU will disappear from civilian use.

Travelli was manager of the RERTR Program since its inception until 2004. The senior scientist has been at Argonne for 40 years and has held various technical and management positions. Travelli and the RERTR program were the subject of a recent major report in the Chicago Tribune.
