INRS researchers improve performance of iron-based catalysts

A breakthrough towards replacing platinum in fuel cells

2011-08-12
(Press-News.org) Quebec City, August 10, 2011 – Having pioneered the development of the first high-performance iron-based catalyst for fuel cells, researchers at INRS recently achieved a second major advance. They developed a new and improved iron-based catalyst capable of generating even more electric power in fuel cells for transportation applications. Previously, only platinum-based catalysts could produce similar performance.

The new research findings from the team of Professor Jean-Pol Dodelet were published in Nature Communications, a prestigious scientific journal part of the Nature Publishing Group. With these new and promising results, we bolster the prospect of iron-based catalysts replacing platinum ones in the electrochemical reduction of oxygen, one of two reactions needed to activate the electric power generator we call a fuel cell. Platinum is rare and very costly, whereas iron is the second most abundant metal on earth and is inexpensive.

"Thanks to this breakthrough we are nearing the day when we will be able to drive electric-electric hybrid vehicles —i.e. battery and fuel cell powered—, which can potentially free us from our current dependence on oil to power our cars," said Professor Dodelet.

Working at the Énergie Matériaux Télécommunications Research Centre in Varennes (Québec), INRS scientists are now focusing on the improvement of the long-term stability (at least 5,000 hours) of these promising new catalysts. "The next step is the most important because it will automatically lead to a high value commercial product, not only for car manufacturers but also for all industrial sectors that use electric power generators or manufacture their components," explained Mr. Dodelet.

'Data motion metric' needed for supercomputer rankings, says SDSC's Snavely

2011-08-12
As we enter the era of data-intensive research and supercomputing, the world's top computer systems should not be ranked on calculation speed alone, according to Allan Snavely, associate director of the San Diego Supercomputer Center (SDSC) at the University of California, San Diego. "I'd like to propose that we routinely compare machines using the metric of data motion capacity, or their ability to move data quickly," Snavely told attendees of the 'Get Ready for Gordon – Summer Institute' being held this week (August 8-11) at SDSC to familiarize potential users with ...

A novel mechanism that regulates pro-inflammatory cells is identified

2011-08-12
NEW YORK, August 10, 2011 - New research led by Derya Unutmaz, MD associate professor, the Departments of Pathology, Medicine, and Microbiology at NYU School of Medicine and Mark Sundrud, PhD, of Tempero Pharmaceuticals, Inc., has identified a novel sensory pathway that modulates the potency of Th17 cell responses. The new research is highlighted in the August 8th online edition of the Journal of Experimental Medicine. The study has found that when memory Th17 cells are exposed to a class of secreted proteins called gamma-c cytokines (IL-2, IL-15 or IL-7), they become armed ...

New American Chemical Society podcast: Banana peels purify contaminated water

2011-08-12
WASHINGTON, Aug. 10, 2011 — To the surprisingly inventive uses for banana peels which include polishing silverware, leather shoes, and the leaves of house plants, scientists have added purification of drinking water contaminated with potentially toxic metals. That's the topic of the latest episode in the American Chemical Society's (ACS) award-winning "Global Challenges/Chemistry Solutions" podcast series. It actually points out that minced banana peel performs better than an array of other traditional purification materials. Gustavo Castro and colleagues note in the ...

Scared of the wrong things: Lack of major enzyme causes poor threat-assessment in mice

2011-08-12
LOS ANGELES — August 10, 2011 — Do you run when you should stay? Are you afraid of all the wrong things? An enzyme deficiency might be to blame, reveals new research in mice by scientists at the University of Southern California. In a paper appearing in the October 2011 issue of the International Journal of Neuropharmacology, USC researchers show that mice lacking a certain enzyme due to genetic mutation are unable to properly assess threat. The mice exhibited defensive behaviors (such as biting or tail rattling) in the presence of neutral stimuli, such as plastic bottles. ...

Children's National collaborates with NIH researchers to identify gene variant in Proteus syndrome

2011-08-12
WASHINGTON, DC—Orthopaedic surgeons from Children's National Medical Center are part of a team of researchers that has identified the genetic mutation causing Proteus syndrome, a rare disorder in which tissue and bone grow massively out of proportion. The discovery appears in the July 27, 2011, online edition of the New England Journal of Medicine. The study, led by researchers at the National Human Genome Research Institute (NHGRI), part of the National Institutes of Health (NIH), may have larger implications in both the identification and treatment of Proteus syndrome, ...

Atlanta runs world's most fiscally efficient airport, Guangzhou boosts efficiency: UBC research

2011-08-12
Atlanta's Hartsfield-Jackson International Airport (ATL), one of the world's busiest international airports is also the most fiscally efficient, says an aviation think-tank based at the University of British Columbia's Sauder School of Business. ATL generated 60 per cent of its total revenue from non-aviation activities, compared to the lowest-ranked North American airport Chicago's O'Hare International Airport (ORD), which derived only 34 per cent of its income from alternative sources. The Air Transport Research Society (ATRS), headquartered at Sauder, has released ...

U.Va. researchers find high energy output from algae-based fuel, but 'no silver bullet'

2011-08-12
Algae-based fuel is one of many options among the array of possible future energy sources. New University of Virginia research shows that while algae-based transportation fuels produce high energy output with minimal land use, their production could come with significant environmental burdens. For farmers looking to maximize profits, algae would produce considerably more transportation energy than canola and switch grass for every hectare planted, and can also be grown on poor-quality marginal land that cannot be easily used to grow food crops such as corn, according ...

Get off the couch, please

2011-08-12
CHICAGO --- Being physically active is one of best ways people with arthritis can improve their health, but a new study from Northwestern University Feinberg School of Medicine shows that more than half of women and 40 percent of men with arthritis are virtually couch potatoes. This is the first study to use a device to objectively measure the physical activity of people with arthritis and determine if they meet federal guidelines. Past research relied on self-reported accounts of exercise and activity. The study was published in Arthritis & Rheumatism, August 2011. Researchers ...
