Bailey geocaches in Mt. Diablo State Park

Geocaching, Nano Wizard,
Government Update in View

This month’s issue of The View, Berkeley Lab’s monthly employee newspaper, features stories on Computational Research Division mathematician David Bailey’s love of geocaching, a new outdoor treasure-hunting sport. Also included is a profile of Materials Science’s Pei Dong Yang, who’s been dubbed a “nanoscience wizard” by his colleagues, a Washington report on the pending appropriations bill, and a photo spread on the installation of the ATLAS silicon pixel detector at CERN. Copies are available in most building mail rooms, as well as the cafeteria lobby and the Building 65 bus stop. Or go here to read it online.


Using Colloids To Change
Nanorod’s Stripes

Striped nanorods
“Striped" nanorods — crystalline materials only a few molecules in thickness and made up of two or more semiconductors — are highly valued for their potential to serve in a variety of nanodevices, including transistors, biochemical sensors and light-emitting diodes (LEDs). Until now the potential of striped nanorods has been limited by the relatively expensive and exacting process required to make them. That paradigm may be shifting. A team led by Berkeley Lab materials scientist Paul Alivisatos has discovered a way to make striped nanorods in a colloid — a suspension of particles in solution. Previously, striped nanorods were only made through epitaxial processes. Full story.

Free Pick-Up
Of Excess Items

The Lab’s Facilities Transportation Group will pick up excess items for two weeks, Monday, Aug. 6 through Friday, August 17, free of charge. When possible, pickups should be arranged through your Division Property Representative, who can provide the Equipment Movement Tags that must accompany excess items. Requests can also be made via the Work Request Center. No account number is needed, just type in “August Clean-Up” in the description box and include a list of pick-up items and their DOE numbers if tagged. Note any items over 500 pounds (they will need special handling and extra time). Contact your Division Safety Liason for pick-up of hazardous waste or computers.

Processors Present
Problems, Payoff


Chip makers are no longer racing to have the fastest microprocessor and have shifted their focus away from building chips with a single, super-fast calculating core. Instead, to save energy and reduce heat, they're putting multiple cores on the same chip -- the equivalent of several computers on the same slice of silicon. The problem is that many software applications weren't written for chips with multiple cores, and the hardware is advancing so fast that the software runs the risk of being left behind. ''You can imagine a scenario where people stop buying laptops and PCs because we can't figure this out,'' said Berkeley Lab computer scientist David Patterson. Full story.

Climate Modeler Coauthors
Article on Global Warming

Bill Collins of the Earth Sciences Division has coauthored an article in the August issue of Scientific American titled "The Physical Science Behind Climate Change," which the magazine headlines as "The Undeniable Case for Global Warming." Collins and his coauthors were members of the international Working Group I, which studied climate science as part of the 2007 report of the Intergovernmental Panel on Climate Change. For more about the article, go here.

Book Chronicles History
Of Particle Accelerators

Former Berkeley Lab Director Andrew Sessler, currently with the Accelerator and Fusion Research Division, has coauthored a new book that for the first time chronicles the development of particle accelerators from the invention of electrostatic accelerators, linear accelerators, and the cyclotron to the colliders of today. The book, “Engines of Discovery: A Century of Particle Accelerators,” also addresses accelerators employed as sources of x-rays, for medical purposes, and in industrial applications. The book identifies the crucial discoveries that have driven the field and gives the reader insight into the people who made these discoveries as well as the methods they used. More on the book is available here.
