Hydrogen Fuel Tech Gets Boost from Low-Cost, Efficient Catalyst

Scientists have engineered a cheap, abundant alternative to the expensive platinum catalyst and coupled it with a light-absorbing electrode to make hydrogen fuel from sunlight and water.

The discovery is an important development in the worldwide effort to mimic the way plants make fuel from sunlight, a key step in creating a green energy economy. It was reported last week in Nature Materials by theorist Jens Nørskov of the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University and a team of colleagues led by Ib Chorkendorff and Søren Dahl at the Technical University of Denmark (DTU).

Tips for Successful Procurement:
Source Selection Workshop May 6

by Alan Kong

SLAC's Supply Chain Management Department will host a 90-minute workshop, entitled "Source Selection" on Friday, May 6 from 9 to 10:30 a.m. in the Kavli Auditorium. The workshop is directed at all SLAC employees who procure outside supplies and services.

Source selection refers to the process of evaluating a competitive proposal to enter into a procurement contract and includes the aspects of choosing a supplier who will provide the best value for SLAC, including the Request for Proposal and the Evaluation processes. Please join us for an interactive session on this topic.

Colloquium Today:
The Road Ahead for Wireless Technology—Dreams and Challenges

Today at 4:15 pm in Panofsky Auditorium, Stanford University Professor of Electrical Engineering Andrea Goldsmith will present "The Road Ahead for Wireless Technology: Dreams and Challenges."

Wireless technology has enormous potential to change the way we live, work and play. Future wireless networks will support gigabit-per-second multimedia communication between people and devices with high reliability and uniform coverage, indoors and out. Wireless technology will also enable smart and energy-efficient homes and buildings, automated highways and skyways, and in-body networks for analysis and treatment of medical conditions. The shortage of spectrum will be alleviated by advances in cognitive and software-defined radios. Many technical challenges must be overcome to make this vision a reality. Goldsmith will describe what the wireless future might look like and some of the innovations and breakthroughs that are required to realize that vision.

Andrea Goldsmith is a professor of Electrical Engineering at Stanford University. While on leave from Stanford, she founded Quantenna Communications, Inc. and served as its Chief Technology Officer. She also held industry positions at Maxim Technologies, Memorylink Corporation, and AT&T Bell Laboratories. She wrote the book "Wireless Communications" and co-wrote the book “MIMO Wireless Communications” (both published by Cambridge University Press). Her research includes work on wireless information and communication theory; multiple-input and multiple-output, or MIMO systems and multihop networks; cognitive radios; sensor networks; "green" wireless system design; and application of communications and signal processing to neuroscience.
