Helping Hydrogen: Student Inventor Tackles Challenge of Hydrogen Storage

$30,000 Lemelson-MIT Collegiate Student Prizes Awarded to Inventive Students Nationwide; Four Leading Institutes Celebrate 2010 Winners

Troy, N.Y. – Determined to play a key role in solving global dependency on fossil fuels, Javad Rafiee, a doctoral student in the Department of Mechanical, Aerospace, and Nuclear Engineering at Rensselaer Polytechnic Institute, has developed a new method for storing hydrogen at room temperature.

Rafiee has created a novel form of engineered graphene that exhibits hydrogen storing capacity far exceeding any other known material. For this innovation, which brings the world a step closer to realizing the widespread adoption of clean, abundant hydrogen as a fuel for transportation vehicles, Rafiee is the winner of the 2010 $30,000 Lemelson-MIT Rensselaer Student Prize. He is among the four 2010 $30,000 Lemelson-MIT Collegiate Student Prize winners announced today.

“Invention is the key ingredient of progress, and the Lemelson-MIT Rensselaer Student Prize rallies our students to innovate world-changing solutions for the grand challenges facing all people of all nations,” said Rensselaer President Shirley Ann Jackson. “Javad Rafiee has the vision of a robust national hydrogen economy and a world less dependent on oil and gasoline. I applaud his efforts toward this noble goal, and congratulate him on this prestigious award. I thank all of the Lemelson-MIT Rensselaer Collegiate Student Prize winners and finalists for their effort, zeal, and for being ambassadors of progress.”

Rafiee is the fourth recipient of the Lemelson-MIT Rensselaer Student Prize. The prize, first given in 2007, is awarded annually to a Rensselaer senior or graduate student who has created or improved a product or process, applied a technology in a new way, redesigned a system, or demonstrated remarkable inventiveness in other ways.

"This year’s winners from the Massachusetts Institute of Technology, California Institute of Technology, Rensselaer Polytechnic Institute, and University of Illinois at Urbana-Champaign shine light on the significance of collegiate invention. They have the ability to transform seemingly implausible ideas into reality and are the true entrepreneurial leaders of their generation,” said Joshua Schuler, executive director of the Lemelson-MIT Program.

Enabling Greener Transportation with Graphene

Hydrogen storage has proven to be a significant bottleneck to the advancement and proliferation of fuel cell and hydrogen technologies in cars, trucks, and other applications. Rafiee has developed a new method for manufacturing and using graphene, an atom-thick sheet of carbon atoms arranged like a nanoscale chain-link fence, to store hydrogen. His solution is inexpensive and easy to produce.

With adviser and Rensselaer Professor Nikhil Koratkar, Rafiee used a combination of mechanical grinding, plasma treatment, and annealing to engineer the atomic structure of graphene to maximize its hydrogen storage capacity. This new graphene has exhibited a hydrogen storage capacity of 14 percent by weight at room temperature – far exceeding any other known material.

This 14-percent capacity surpasses the U.S. Department of Energy 2015 target of realizing a material with hydrogen storage capacity of 9 percent by weight at room temperature. Rafiee said his graphene is also one of the first known materials to surpass the Department of Energy’s 2010 target of 6 percent.

Rafiee’s graphene exhibits three critical attributes that result in its unique hydrogen storage capacity. The first is high surface area. Graphene’s unique structure, only one atom thick, means that each of its carbon atoms is exposed to the environment and, in turn, to the hydrogen gas. The second attribute is low density. Graphene has one of the highest surface area-per-unit masses in nature, far superior to even carbon nanotubes and fullerenes

The third attribute is favorable surface chemistry. After oxidizing graphite powder and mechanically grinding the resulting graphite oxide, Rafiee synthesized the graphene by thermal shock followed by annealing and exposure to argon plasma. These treatments play an important role in increasing the binding energy of hydrogen to the graphene surface at room temperature, as hydrogen tends to cluster and layer around carbon atoms.

Talented Engineer

Rafiee joined Rensselaer in 2008, following an internship at the City University of Hong Kong and earning his bachelor’s and master’s degrees in mechanical and manufacturing engineering from the University of Tabriz in Iran. At Rensselaer, Rafiee and his brother, Mohammad, joined the research group of Mechanical, Aerospace, and Nuclear Engineering Professor Nikhil Koratkar.

“Javad is extremely knowledgeable, has great confidence in his abilities, and has demonstrated a very high level of creativity and originality. However, it is his deep passion and enthusiasm for research and discovery coupled with his amazing drive and energy that differentiates him from his peers,” Koratkar said. “This passion and excitement for discovery and innovation is not something that can be taught or learned. It is an intrinsic quality of an individual – either you have it or you don’t – and Javad is the most intellectually curious student I have ever had the privilege to advise here at Rensselaer.”

In his time at Rensselaer, Rafiee has authored five, and co-authored three, journal papers in various disciplines, ranging from materials science and mechanical engineering, to computer science and urology.

Rafiee is from Tehran, Iran, and expects to earn his doctorate in 2011. Following graduation, he and his brother plan to start their own business with a focus on clean energy and green manufacturing.

Lemelson-MIT Collegiate Student Prizes

In addition to Rafiee’s pioneering work, the other winners of the annual Lemelson-MIT Collegiate Student Prize were announced today at their respective universities:

• Lemelson-MIT Student Prize winner Erez Lieberman-Aiden demonstrated creativity and innovation across several disciplines, most recently with his invention of “Hi-C”, a three-dimensional genome sequencing method that will enable an entirely new understanding of cell state, genetic regulation and disease.

• Lemelson-MIT Caltech Student Prize winner Heather Agnew contributed to the development of an innovative technique that creates inexpensive, stable, highly reliable biochemical compounds that have the potential to replace antibodies used in many standard diagnostic tests.

• Lemelson-MIT Illinois Student Prize winner Jonathan Naber and the Illini Prosthetics Team developed an affordable, durable, extremely functional prosthetic arm for people in underdeveloped countries, made from recycled materials.

New Computer Model Predicts How Fracturing Metallic Glass Releases Energy at the Atomic Level

Metallic glasses are an exciting research target for tantalizing applications; however, the difficulties associated with predicting how much energy these materials release when they fracture is slowing down development of metallic glass-based products. Recently, researchers developed a way of simulating to the atomic level how metallic glasses behave as they fracture. This modeling technique could improve computer-aided materials design and help researchers determine the properties of metallic glasses. The duo reports their findings in the Journal of Applied Physics.

The Relationship Between Charge Density Waves and Superconductivity? It's Complicated.

For a long time, physicists have tried to understand the relationship between a periodic pattern of conduction electrons called a charge density wave (CDW), and another quantum order, superconductivity, or zero electrical resistance, in the same material. Do they compete? Co-exist? Co-operate? Do they go their separate ways?

Splitting Water: Nanoscale Imaging Yields Key Insights
