HEADLINES – UCLA Samueli In The News 2014
‘Bed of Nails’ Surfaces Just Won’t Get Wet
Researchers from UCLA Engineering reported that they’ve engineered glass and metal surfaces to repel virtually all fluids. To do so, they etched the surfaces to resemble a bed of nails, with the heads of the nails—each 20 micrometers across—facing up. The UCLA researchers included Chang-Jin “CJ” Kim, professor of mechanical and aerospace engineering and post-doctoral scholar Tingyi “Leo” Liu, a Ph.D. alumnus of the school.

Precision Plasma Wakefield Acceleration
Accelerators based on plasmas, which can sustain electric fields orders of magnitude larger than conventional accelerators, could one day be a smaller and cheaper alternative. But the precision engineering required to accelerate particles efficiently and uniformly has been a challenge. Now UCLA’s Chandrashekhar Joshi and colleagues at the SLAC National Accelerator Laboratory have made a leap forward.

High Power Terahertz Radiation at Room Temperature
Researchers at UCLA, led by Mona Jarrahi, associate professor of electrical engineering, have used plasmonic photomixing to develop a room-temperature terahertz source with not only high spectral purity and broad tunability, but with nearly 1 mW of optical power at terahertz frequencies—significantly higher than previously demonstrated photomixing-based terahertz radiation sources.

Scientists have proven that a technique for accelerating particles on waves of plasma is efficient enough to power a new generation of shorter, more economical particle accelerators. UCLA Engineering’s Chan Joshi led the team that developed the plasma source used in the experiment. Computer simulations used in the experiments were developed by Warren Mori’s group at UCLA. News on the research, which was published in Nature, was also carried in Science; The Conversation (U.K.); Scientific American; and ArsTechnica.

Secret Trails Near Downtown L.A. Require Smart Phone to Find Them
Excessive screen time with electronic devices is the bane of many parents who wish their kids would spend more time in the fresh air and sunshine. A new website, developed at UCLA’s Interpretive Media Laboratory, is embracing mobile technology as a way of encouraging people to get out and explore urban Los Angeles.
Water-Repelling Surfaces Made Stable
Superhydrophobic surfaces, like those on certain water bugs, repel water by trapping air between tiny protrusions. Engineers are looking at superhydrophobic coatings as a way to reduce drag in pipes and on boats. However, in most lab tests, the trapped air escapes within an hour. Chang-Jin “CJ” Kim and his graduate students at UCLA, wanted to see if artificial superhydrophobes could be made more stable.
