Direct nitrogen fixation for low cost energy conversion

A simple, low-cost and eco-friendly method of creating nitrogen-doped graphene nanplatelets (NGnPs), which could be used in dye-sensitized solar cells and fuel cells, is published in Scientific Reports today. The work, carried out at Ulsan National Institute of Science and Technology (UNIST) in South Korea, could be a step towards replacing conventional platinum (Pt)-based catalysts for energy conversion.

World’s 14th-fastest supercomputer launches at WPAFB

The 14th-fastest supercomputer in the world was officially launched July 22 at Wright-Patterson Air Force Base.┬áThe $25 million SGI ICE X model supercomputer, named “Spirit” after the Air Force’s B-2 advanced bomber for its power and ability to deliver, was unveiled at the Air Force Research Laboratory (AFRL) Department of Defense (DOD) Supercomputing Resource Center (DSRC) in Bldg. 802, Area B, before Air Force dignitaries and members from the U.S. House of Representatives. The ribbon-cutting ceremony was hosted by Maj. Gen. William McCasland, AFRL Commander.

Penn Researchers Help Show New Way to Study and Improve Catalytic Reactions

Catalysts are everywhere. They make chemical reactions that normally occur at extremely high temperatures and pressures possible within factories, cars and the comparatively balmy conditions within the human body. Developing better catalysts, however, is mainly a hit-or-miss process. Now, a study by researchers at the University of Pennsylvania, the University of Trieste and Brookhaven National Laboratory has shown a way to precisely design the active elements of a certain class of catalysts, showing which parameters are most critical for improving performance.
