Building green performance motorcycles
04/17/12 — Electric motorcycles are quiet, and from a power perspective more efficient. Both traits are not lost on the rider. “If you get on these electric motorcycles the first thing you notice is a magic carpet ride feel,” says Abe Askenazi, B.S'92, M.S'94 ME. “It's almost like flying. It feels like you are on a glider and this thing is propelling you forward. You don't hear all of the drama of power production, you are just doing it.” Askenazi has traveled a long road to become the chief technology officer at Zero Motorcycles, one of the nation's leading electric motorcycle manufacturers.

Monthly measurements help water managers estimate the amount of water held in the snowpack and allow them to allocate the state's most precious resource. Now, the Sierra Nevada is going high tech. Wireless sensors developed by Steven Glaser, professor of civil and environmental engineering, are being tested in an ambitious pilot project at the UC Merced Sierra Nevada Research Institute.
Replacing the Osterizer as standard lab equipment
03/19/12 — After a year in Asia and South America visiting research labs that lacked the basics, Lina Nilsson - a post-doctoral researcher in the bioengineering lab of professor Daniel Fletcher - and a team of engineering colleagues brainstormed about how to develop low-cost, accessible tools that could produce research-grade results. The team evolved into Tekla Labs, a cooperative of ten partners from Berkeley Engineering and UCSF. Their idea won first place for social entrepreneurship in the 2010-11 Big Ideas @ Berkeley contest.
Maker of resonators
03/19/12 — Most days (and nights), you'll find Ernest Ting-Ta Yen, a mechanical engineering Ph.D. student, immersed in the complexities of his microelectromechanical systems research. The aluminum nitride resonators he builds, aimed at new cell phones and communications applications, are designed to help shrink mobile devices while increasing functionality. Happen upon him in his graduate student office at midnight, though, and you'll hear lovely strains of music. Yen practices from midnight to 2 a.m., the only hours available to this busy researcher.
Girls meet ‘the science of better’
02/09/12 — Industrial engineering professor Rhonda Righter (M.S'82, Ph.D'86 IEOR) is tackling a new assignment: serving as a volunteer role model to 35 middle-school girls. Visiting an after-school science enrichment program called Techbridge, Righter described her field and how she chose it to a group of students at Oakland's American Indian Public Charter School. Her presentation was intended to introduce the girls to engineering with the hope that they will one day be inspired to pursue studies and careers in it or a related field. “Industrial engineering is all about making things better,” Righter explained. “We're like detectives who solve puzzles.”
Self-assembling nanorods: Berkeley researchers obtain 1, 2 and 3D nanorod arrays and networks
02/01/12 Berkeley Lab — A relatively fast, easy and inexpensive technique for inducing nanorods to self-assemble into one-, two- and even three-dimensional macroscopic structures has been developed by a team of Lawrence Berkeley National Laboratory researchers. Leading this project was Ting Xu, a polymer scientist who holds joint appointments with Berkeley Lab's Materials Sciences Division and UC Berkeley's Departments of Materials Science and Engineering, and Chemistry.

Berkeley Lab research sparks record-breaking solar cell performances
11/07/11 Berkeley Lab — Theoretical research by scientists at LBNL has led to record-breaking sunlight-to-electricity conversion efficiencies in solar cells. The researchers showed that, contrary to conventional scientific wisdom, the key to boosting solar cell efficiency is not absorbing more photons but emitting more photons. "A great solar cell also needs to be a great Light Emitting Diode," says Eli Yablonovitch, the UC Berkeley professor of electrical engineering who led this research.
Manufacturing: The road to economic recovery
10/17/11 — We have become a nation of traders, regulators and middle parties. But are we still a nation of designers and makers?
In the 1950s, manufacturing contributed more than 25 percent of the U.S. gross domestic product. Today, that share has fallen to below 12 percent. China is rapidly overtaking the United States as the world's largest manufacturing nation.
The brittleness of aging bones – more than a loss of bone mass
08/29/11 Berkeley Lab — New research at Berkeley shows that at microscopic dimensions, the age-related loss of bone quality can be every bit as important as the loss of quantity in the susceptibility of bone to fracturing. Using a combination of x-ray and electron based analytical techniques as well as macroscopic fracture testing, the researchers showed that the advancement of age ushers in a degradation of the mechanical properties of human cortical bone over a range of different size scales. "In characterizing age-related structural changes in human cortical bone at the micrometer and sub micrometer scales, we found that these changes degrade both the intrinsic and extrinsic toughness of bone," says Berkeley Engineering materials scientist Robert Ritchie.
Building the bio toolkit
05/04/11 — In the 1970s, the Berkeley-bred SPICE (Simulation Program with Integrated Circuit Emphasis) revolutionized microelectronics by creating a toolkit now used worldwide as the standard for circuit design.
