*Scientists Build the First Wafer-Scale Graphene Integrated Circuit Smaller than a Pinhead*

Yorktown Heights, NY – 10 Jun 2011: Today, IBM Research scientists announced that they have achieved a milestone in creating a building block for the future of wireless devices. In a paper published yesterday in the magazine Science, IBM researchers announced the first integrated circuit fabricated from wafer-size graphene, and demonstrated a broadband frequency mixer operating at frequencies up to 10 gigahertz (10 billion cycles/second).

Designed for wireless communications, this graphene-based analog integrated circuit could improve today’s wireless devices and points to the potential for a new set of appli-cations. At today’s conventional frequencies, cell phone and transceiver signals could be improved, potentially allowing phones to work where they can’t today while, at much higher frequencies, military and medical personnel could see concealed weapons or conduct medical imaging without the same radiation dangers of X-rays.

Novel Nanowires Boost Fuel Cell Efficiency

Fuel cells have been touted as a cleaner solution to tomorrow’s energy needs, with potential applications in everything from cars to computers.

But one reason fuel cells aren’t already more widespread is their lack of endurance. Over time, the catalysts used even in today’s state-of-the-art fuels cells break down, inhibiting the chemical reaction that converts fuel into electricity. In addition, current technology relies on small particles coated with the catalyst; however, the particles’ limited surface area means only a fraction of the catalyst is available at any given time.
