How to measure an oil spill

02/02/11 — When oil was flowing from BP's broken well at the bottom of the Gulf of Mexico last spring, the company estimated the flow rate at about 1,000 barrels a day. But news outlets wanted an independent estimate. Could Ömer Savaş, an expert in fluid mechanics and turbulent flows, help? Soon Savaş became involved in a national effort to establish the “official” flow rate, a number that would dictate not only the level of resources assigned to the cleanup but also its legal ramifications once the emergency had passed.

A leading figure in the emerging field of neuromarketing, he conducts market research by studying how the subconscious mind responds to a variety of flavors, designs and sales pitches. His Berkeley-based company, NeuroFocus, advises companies on everything from developing a new product to packaging, marketing and advertising.

A 411 on water’s next drop

02/02/11 — In the south India city of Hubli, turning on the tap is no easy task. Residents frequently skip work, postpone errands or keep children home from school in anticipation of the precious-but notoriously unreliable-arrival of water along urban pipelines. Missing a delivery can translate into days without household water. “Literally, people wait around their house until the water comes on,” says Anu Sridharan (B.S'09, M.S'10 CEE). Sridharan is part of a Berkeley-based student team pursuing a novel-but surprisingly simple-fix to what is a common occurrence in the developing world. Their project, called NextDrop, deploys ubiquitous mobile phones to alert residents when water is flowing in a neighborhood.

Berkeley scientists create more efficient photocatalyst for use in clean technologies

01/29/11 AZoM — A little disorder goes a long way, especially when it comes to harnessing the sun's energy. Scientists from Berkeley Lab jumbled the atomic structure of the surface layer of titanium dioxide nanocrystals, creating a catalyst that is both long lasting and more efficient than all other materials in using the sun's energy to extract hydrogen from water. "We are trying to find better ways to generate hydrogen from water using sunshine," says Samuel Mao, a mechanical engineering professor and scientist in Berkeley Lab's Environmental Energy Technologies Division who led the research.

What he learns from earthquakes prepares us for the big one

01/26/11 Contra Costa Times — The findings of Jonathan Bray, professor of geotechnical engineering at UC Berkeley, help determine whether a building can withstand an earthquake. "The science is focused on engineering systems that are supported on or within the earth," he said. "Whether it's foundations for buildings, building an earth dam or constructing a lifeline like a highway, we have to understand the stability of the geology, the soil and the rock."

Hotspots tamed by BEAST: Secrets of mysterious metal hotspots uncovered by new single molecule imaging technique

01/19/11 Berkeley Lab — The secrets behind the mysterious nano-sized electromagnetic "hotspots" that appear on metal surfaces under a light are finally being revealed with the help of a BEAST. Using the Brownian Emitter Adsorption Super-resolution Technique (BEAST), "we were able to map the electromagnetic field profile within a single hotspot as small as 15 nanometers with an accuracy down to 1.2 nanometers, in just a few minutes," says Xiang Zhang, a principal investigator with Berkeley Lab's Materials Sciences Division and the Ernest S. Kuh Endowed Chaired Professor of Mechanical Engineering at UC Berkeley.

UC Berkeley will host Cal Science & Engineering Festival on Sunday

01/18/11 San Jose Mercury News — On Sunday, UC Berkeley will host the free, family-oriented Cal Science & Engineering Festival on campus. The festival will showcase the university's champion unicycle basketball team displaying their "physics" skills, a chemistry magic show and the Banana Slug String Band. Hands-on offerings include viewings through solar telescopes, earthquake demonstrations, fossil displays and a chance for children to power appliances with solar energy.

Berkeley zero net energy cottage deserves study

01/11/11 San Francisco Chronicle — Karen Chapple, an associate professor of city and regional planning at UC Berkeley, has built a 450-square-foot cottage that lays claim to "zero net energy status." With the help of students from UC Berkeley engineering professor Ashok Gadgil's civil and environmental engineering course and a grant from the UC Transportation Center for further study, Chapple built the cottage this fall for $98,000, and wants to see further development in this housing trend.

Microsoft’s Xbox Kinect beyond hackers, hobbyists

01/10/11 San Francisco Chronicle — Microsoft's Kinect, a motion-tracking peripheral for the Xbox console that is packed with an irresistible blend of cameras and sensors, is finding popularity among researchers such as UC Berkeley engineering graduate student Patrick Bouffard. Working out of Professor Claire Tomlin's lab, Bouffard built a Kinect-enhanced robotic helicopter that perceives objects in its path. A video of the device has been a viral hit on YouTube.

99.999% reliable? Don’t hold your breath

01/08/11 The New York Times — AT&T's dial tone was engineered so that 99.999 percent of the time, you could successfully make a phone call. Can we realistically expect that such availability will ever come to Internet services? "Google doesn't have the luxury of scheduled downtime for maintenance," says Armando Fox, an adjunct associate professor in the College of Engineering at UC Berkeley. Nor can it take down the service, he says, to install upgrades. "It is not uncommon for a place like Google to push out a major release every week," he said, adding that such frequency is "unprecedented" for the software industry.

Chlorine substitutes in water may have risks

01/07/11 National Public Radio — Water systems across the country are changing the way they disinfect drinking water because the traditional disinfectant, chlorine, can leave behind toxic chemicals. But alternatives to chlorine are turning out to have risks of their own, says UC Berkeley professor of civil and environmental engineering David Sedlak, who wrote an analysis in the journal Science.
