Hydrogen-rich Material Promises Advances in Energy Transmission, Fuel Storage

Researchers at the Stanford Institute for Materials and Energy Science, a joint institute of SLAC and Stanford University, have produced a hydrogen-rich alloy that could provide insight into the properties of metallic hydrogen, according to a study published in the August 17 issue of Proceedings of the National Academy of Sciences. The work is a step toward materials with revolutionary implications for energy science, enabling lossless power transmission, next-generation particle accelerators and even magnetic levitation.

Metallic hydrogen is a state of hydrogen predicted to form under ultra-high pressure. If achieved, some researchers predict it could function as a room-temperature superconductor—a material capable of conducting electricity with zero resistance at temperatures above 0 degrees Celsius. But because the pressure required to make metallic hydrogen is so enormous—much greater the pressure experienced by materials in the center of the earth—researchers have had little luck in producing it.

"People are very interested in hydrogen because it's element one," said SIMES physicist Wendy Mao, who was a co-author on the study. "At high enough pressure, it should be metallic and it should be a room temperature superconductor."  Read more...

August 2009 Issue of Symmetry Now Online

We’ve been calling this our Manga issue because it highlights the work of Takuya Uruno, who created a physics Manga series for kids for the Japanese laboratory KEK—featured in our gallery—and also drew us a gorgeous Manga cover.

The new issue also features:

Recycling Tip of the Week:
Software and Memory Storage Devices

(Image - floppy discs)

All software, zip disks, compact disks, flash drives, and other memory storage devices that are no longer needed should be taken to SLAC Salvage for proper disposal or recycling.

To submit these items, please complete a salvage form (parts A & B), then put the form and the items in the SLAC inter office mail, to the Property Control/Salvage Warehouse, Mail Stop 85A (x2329). Alternately, you can drop them off at the Salvage Warehouse, at the south end of Building 28. For more information, contact the Salvage Department (x2329).
