At the intersection of engineering and music, Yale students hit the right notes

During the holiday season, it’s not unusual to be serenaded by Yale’s many choirs and a cappella ensembles caroling around campus. But this past December, only in Yale’s Center for Engineering Innovation & Design (CEID) could you be treated to an impromptu reggae jam played on one-of-a-kind instruments. (more…)

Cooling Microprocessors with Carbon Nanotubes

Technique From Berkeley Lab’s Molecular Foundry Could Also Work with Graphene

“Cool it!” That’s a prime directive for microprocessor chips and a promising new solution to meeting this imperative is in the offing. Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a “process friendly” technique that would enable the cooling of microprocessor chips through carbon nanotubes.

Frank Ogletree, a physicist with Berkeley Lab’s Materials Sciences Division, led a study in which organic molecules were used to form strong covalent bonds between carbon nanotubes and metal surfaces. This improved by six-fold the flow of heat from the metal to the carbon nanotubes, paving the way for faster, more efficient cooling of computer chips. The technique is done through gas vapor or liquid chemistry at low temperatures, making it suitable for the manufacturing of computer chips. (more…)

UCLA Engineers Develop New Energy-Efficient Computer Memory Using Magnetic Materials

MeRAM is up to 1,000 times more energy-efficient than current technologies

By using electric voltage instead of a flowing electric current, researchers from UCLA’s Henry Samueli School of Engineering and Applied Science have made major improvements to an ultra-fast, high-capacity class of computer memory known as magnetoresistive random access memory, or MRAM.

The UCLA team’s improved memory, which they call MeRAM for magnetoelectric random access memory, has great potential to be used in future memory chips for almost all electronic applications, including smart-phones, tablets, computers and microprocessors, as well as for data storage, like the solid-state disks used in computers and large data centers.

Putting a New Spin on Computing

*Physicists at the UA have achieved a breakthrough toward the development of a new breed of computing devices that can process data using less power.

In a recent publication in Physical Review Letters, physicists at the University of Arizona propose a way to translate the elusive magnetic spin of electrons into easily measurable electric signals. The finding is a key step in the development of computing based on spintronics, which doesn’t rely on electron charge to digitize information.

Unlike conventional computing devices, which require electric charges to flow along a circuit, spintronics harnesses the magnetic properties of electrons rather than their electric charge to process and store information. (more…)

IBM Microprocessors to Power the New Wii U System from Nintendo

Armonk, NY, USA – 07 Jun 2011: IBM today announced that it will provide the microprocessors that will serve as the heart of the new Wii U™ system from Nintendo.  Unveiled today at the E3 trade show, Nintendo plans for its new console to hit store shelves in 2012.

The all-new, Power-based microprocessor will pack some of IBM’s most advanced technology into an energy-saving silicon package that will power Nintendo’s brand new entertainment experience for consumers worldwide. IBM’s unique embedded DRAM, for example, is capable of feeding the multi-core processor large chunks of data to make for a smooth entertainment experience. (more…)

Berkeley Lab Researchers Create Nanoscale Waveguide for Future Photonics

The creation of a new quasiparticle called the “hybrid plasmon polariton” may throw open the doors to integrated photonic circuits and optical computing for the 21st century. Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have demonstrated the first true nanoscale waveguides for next generation on-chip optical communication systems.

“We have directly demonstrated the nanoscale waveguiding of light at visible and near infrared frequencies in a metal-insulator-semiconductor device featuring low loss and broadband operation,” says Xiang Zhang, the leader of this research. “The novel mode design of our nanoscale waveguide holds great potential for nanoscale photonic applications, such as intra-chip optical communication, signal modulation, nanoscale lasers and bio-medical sensing.” (more…)
