Exoskeleton lets UC Berkeley grad take a huge step

05/15/11 San Francisco Chronicle — When Austin Whitney, a paralyzed 22-year-old UC Berkeley student, rose from his wheelchair and stepped across the commencement stage on Saturday to shake Chancellor Robert Birgeneau's hand, the crowd of 15,000 at Edwards Stadium went wild with cheers, as if witnessing a miracle. A team of UC Berkeley mechanical engineers - four doctoral students led by Professor Homayoon Kazerooni - have been developing a computerized body brace called an exoskeleton they believe will be good enough to transform thousands of wheelchair users into walking people in a couple of years, and for an affordable price.

Sun-driven and Australia-bound

05/04/11 — To build a car powered completely by the sun, a team of Berkeley students is burning lots of midnight oil. A year-and-a-half in the making, a sleek vehicle called Impulse was unveiled at Cal Day and is on track to compete in the world's premier solar car race this October. Behind the effort is the 73-member crew of CalSol, the campus's student-run solar vehicle team. This fall, 15 to 20 students will withdraw from school for the semester to participate in CalSol's first-ever entry in the World Solar Challenge, an 1,800-mile road race across Australia.

The laser whisperer

03/02/11 — A research team led by Xiang Zhang, professor of mechanical engineering and faculty scientist at Lawrence Berkeley Laboratory, has taken inspiration from the phenomena of whispering galleries - such as the U.S. Capitol's Statuary Hall or Grand Central Terminal in New York - and their remarkable acoustical features to achieve a major scientific breakthrough in the use of plasmon lasers. By creating a technique to bounce surface plasmons inside of a nanosquare device, much in the way sound waves reflect back and forth in a whispering gallery, the team was able to operate plasmon lasers at room temperature, overcoming what had been a major barrier to practical utilization of the technology.

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.

This is your brain on neuromarketing

02/02/11 — When it comes to the quest for a better potato chip, a sleeker cell phone or a knockout TV ad, A.K. Pradeep (Ph.D'92 ME) believes in digging deep. 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.

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.

Think globally, surf locally

10/05/10 — Modern surfboards are made with polyurethane foam, fiberglass and epoxy resin, decidedly unromantic and toxic petrochemicals that can harm workers and the environment during manufacture, then languish in landfills at the end of their life. Many manufacturers are making surfboards greener by switching to natural materials. They're doing the right thing, right? Not necessarily, says 26-year-old Tobias Schultz (M.S.'10 ME), a lightly tanned, blond-ponytailed Santa Cruz native who just graduated with his mechanical engineering master's and a certificate in Engineering and Business for Sustainability. He is also the author of an extensive study on the carbon footprint of the surfing lifestyle.

In search of an earthquake-proof building

03/02/10 CNN.com — Earthquakes alone don't kill people; collapsed buildings do. But can people engineer buildings that wouldn't crumble when subjected to the rumblings of the Earth? High costs keep countries such as Haiti from adopting the latest building techniques and technologies, said Nicholas Sitar, professor of civil and environmental engineering at UC Berkeley. He said making buildings more basic might actually make them stronger and would cost less than high-tech upgrades
