Brian Maroney, the Caltrans toll bridge chief design engineer, is the featured speaker for the Nano-High lecture tomorrow, Feb. 1, at 10 a.m. in 1 Pimentel Hall on campus. He will talk about careers in engineering and, in particular, the challenge of designing an aesthetically iconic structure with a 100-year lifetime in one of the most active earthquake zones in the world. (The subject of bolts may come up.) Lab employees are encouraged to invite their high-school age children or acquaintances to attend. Adults will be accommodated on a space-available basis.

A high-throughput scintillator discovery project lead by Stephen Derenzo (pictured) of Life Sciences and Edith Bourret-Courchesne of Material Sciences, in collaboration with Andrew Canning of Computational Research, has received an Inter-Agency Agreement (IAA) award of over $1.3M from the Domestic Nuclear Detection Office (DNDO) for 2014. The project uses empirical rules to select the most promising candidates from the vast number of possible compounds and then uses unique custom-built high-throughput systems for synthesis and characterization. The project has been very successful at identifying new high-luminosity scintillators: Of the 33 new scintillators that were published after 2005 with luminosities above 30,000 photons/MeV, 20 (61%) were discovered by this project.
Alphabet Energy was featured as a 2014 Technology Pioneer at the World Economic Forum (WEF) last week in Davos, Switzerland. Technology pioneers are selected by WEF for their potential to generate new opportunities and innovative solutions. Alphabet Energy, a startup based on advanced materials technologies developed at Berkeley Lab, has raised $30 million to date and is poised to introduce low-cost products that convert waste heat into electricity.

Alex Zettl of the Materials Sciences Division, and a member of the Kavli Energy NanoSciences Institute at Berkeley, has won the 2013 Foresight Institute Feynman Prize for Nanotechnology Experiment. Named in honor of Nobel laureate Richard Feynman whose seminal essay, “There’s Plenty of Room at the Bottom,” is widely credited with launching the field of nanoscience, the Feynman prizes — one for theoretical work and one for experimental research — annually recognize scientists whose work has advanced Feynman’s vision. Zettl was cited for his “exceptional work in the fabrication of nanoscale electromechanical systems, spanning multiple decades and including carbon nanotube-based bearings, actuators, and sensors brought to fruition with cutting-edge nanoscale engineering.” More>
Ali Javey, a faculty scientist in the Materials Sciences Division, led the creation of electronic whiskers, highly sensitive tactile sensors made from carbon nanotubes and silver nanoparticles that respond to pressure as slight as a single Pascal, the pressure of a dollar bill on a tabletop. Among many possibilities, these e-whiskers could give robots new abilities to “see” and “feel” their environment, plus a better sense of balance. Other potential applications include the monitoring of airflow and wearable sensors for measuring heart beat and pulse rate. Also working on this project were Kuniharu Takei, Zhibin Yu, Maxwell Zheng, Hiroki Ota and Toshitake Takahashi. More>
Chuck Fadley and Alex Gray of the Materials Sciences Division, working at the Advanced Light Source, led the development of a technique that makes it possible for the first time to selectively study the electronic structure of buried interfaces in multilayer nanodevices. The technique, which is called SWARPES for Standing Wave Angle-Resolved Photoemission Spectroscopy, can be applied to any multilayer prototype device structure pertaining to spintronics, high-temperature superconductors and semiconductor electronics. Berkeley Lab contributors to this research included Aaron Bostwick, Eli Rotenberg, Giuseppina Conti, Daria Eiteneer, Arunotha Rattanachata, Albert Greer, James Ciston, Colin Ophus and Jeff Kortright.

Scientists from SLAC, Stanford and Berkeley Lab grew sheets of an exotic material in a single atomic layer and measured its electronic structure for the first time. They discovered it’s a natural fit for making thin, flexible light-based electronics. In a study published Dec. 22 in Nature Nanotechnology, the researchers give a recipe for making the thinnest possible sheets of the material, called molybdenum diselenide or MoSe2, in a precisely controlled way, using a technique that’s common in electronics manufacturing.

[R&D Magazine] A UC Berkeley team led by Berkeley Lab materials scientist Ali Javey has created a material that moves quickly in response to light. The material is made with carbon nanotubes layered onto a plastic polycarbonate membrane. The nanotubes can, within fractions of a second, absorb light, convert it into heat and transfer the heat to the plastic surface. The plastic expands in response to the heat, while the nanotube layer does not, causing the material to bend. “The advantages of this new class of photoreactive actuator,” Javey says, are that “it is very easy to make, and it is very sensitive to low-intensity light.” More>
Employees are encouraged to invite their high-school aged children or acquaintances to attend Nano*High tomorrow at 10 a.m. in 1 Pimentel Hall on the UC Berkeley campus. Professor Susan Lynch will discuss “Your Microbiome in Health and Disease.” There are 10 times as many bacteria as human cells in the body and it has been suggested that they affect metabolism, immune function, antibiotic use, and perhaps mental disorders. Studying them is difficult because required growth conditions have not been reproduced in the lab. However, recent advances in DNA sequencing and the development of metagenomics have now made it feasible to analyze the entire human microbiome and study its impact on our lives. More>
Daniel Kasen (Nuclear Science), Adam Weber (EETD), Junqiao Wu (Materials Sciences), and Ahmet Yildiz (Physical Biosciences), are recipients of Presidential Early Career Awards, the highest honor bestowed by the U.S. Government on science and engineering professionals in the early stages of their career. Kasen and Weber were recognized as part of the Department of Energy, while Wu and Yildiz, who are also UC Berkeley faculty members, were recognized as part of the National Science Foundation. More>
