SLAC to Join New Energy Frontier Research Efforts

The Department of Energy has funded 46 new projects that will investigate ways to make the U.S. energy economy greener and more secure. SLAC will contribute substantially to at least three of these Energy Frontier Research Centers.

Each of the 46 EFRCs, which the White House announced April 27, will receive between two and five million dollars per year for five years—a total DOE commitment of $777 million. One project, run out of the National Renewable Energy Laboratory in Golden, Colorado, will use the Stanford Synchrotron Radiation Lightsource at SLAC to help identify more efficient materials for solar energy conversion. Another, based at Oak Ridge National Laboratory, will try to find new ways to develop super-strong, radiation-tolerant materials, with possible applications in energy infrastructure. The Oak Ridge center will employ SLAC's Linac Coherent Light Source in this effort.

Stanford will host a third EFRC. The Center on Nanostructuring for Efficient Energy Conversion will research and characterize materials at the nanoscale—anything smaller than about 100 nanometers, or one-thousandth the diameter of a human hair—with the aim of advancing basic design principles for next-generation batteries, capacitors, fuel cells and solar cells. SLAC physicist David Goldhaber-Gordon, also an associate professor of physics at Stanford, is involved in this project.

"My role is to bring a physicist's perspective, to complement the engineers' perspective," Goldhaber-Gordon said. "I can give a sense of what new things can happen when you design things on the nanoscale."   Read more...

Reminder: Financial Overview Class Tomorrow

Any staff member with budgetary responsibilities is invited to attend this one-hour session. Charlotte Chang of Strategic Financial Planning will present the class on May 19, from 1:30 to 2:30 p.m. in the Yellow Room, Building 41. Please register on the Training Web site. Enter key search: FINOVR. Please contact Charlotte Chang (x2717) or Sylvia Rupilius (x4345) with questions.

Colloquium Today:
Glimpse of the Neutrino in Graphene

(Image - SLAC Colloquium banner)

Today at 4:15 p.m. in Panofsky Auditorium, Stanford Assistant Professor of Physics Hari Manoharan will present "Glimpse of the Neutrino in Graphene."

Quantum electrodynamics and condensed-matter physics are experiencing a tantalizing convergence under the rubric of "Dirac materials"—crystals hosting charge carriers more aptly described by the Dirac equation than the Schr√∂dinger equation. Graphene is emerging as a prototype two-dimensional Dirac material and has been proposed as a condensed-matter nanolaboratory for relativistic particle experiments, but with exceptional accessibility since the effective speed of light is scaled down by a factor of about 300. This talk will survey the Manoharan lab's low-temperature experiments in which the unique symmetries of Dirac electrons are graphically revealed by scanning tunneling microscopy applied as a coherent nanoscale probe. These ideas and measurements are now being extended to nanostructures and to three-dimensional topological materials.

The talk is free and open to all.

Special Stanford-SLAC Colloquium Tomorrow

In a special event at 4:15 p.m. tomorrow in Panofsky Auditorium, Leonardo Senatore from the Institute for Advanced Study will present "Non-Gaussianities: Probing High Energy Physics with Cosmological Observations."

Around SLAC: Bike to Work Day 2009

Last Thursday, 72 cyclists signed in with SLAC volunteers manning tables for Bike to Work Day 2009. Another 28 bike commuters and many recreational cyclists rode by. Volunteers handed out bike bags containing an energy bar, coupons and bicycling literature, supplied by and the Silicon Valley Bicycle Coalition and their sponsors. Cyclists also enjoyed bagels, orange juice and bottled water courtesy of Bike to Work Day sponsors Safeway and Eric's Gourmet. 

Thanks to all for a safe and successful day.
