Invention produces cleaner water with less energy and no filter

The same technology that adds fizz to soda can now be used to remove particles from dirty water. Researchers at Princeton University have found a technique for using carbon dioxide in a low-cost water treatment system that eliminates the need for costly and complex filters. (more…)

Prize-Winning Mentor Menachem Elimelech Encourages a Life of Balance

When it comes to advising graduate students and postdoctoral scholars, Yale faculty member Menachem Elimelech believes his job isn’t rocket science.

“I’m here to help them achieve their goals, and if they are motivated, that is very easy,” says Elimelech, the Roberto Goizueta Professor of Chemical and Environmental Engineering. “All I have to do is give them freedom to pursue their scientific passions, inspire them, take interest in their work and in their lives beyond the lab, and treat them as individuals — not as people whose sole function is to produce scientific data.

“And, I’m patient with them,” he adds. “They’re young.” (more…)

Made in IBM Labs: Researchers Unveil Nanotechnology Circuits for Wireless Devices

*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.
