A new technique developed at Berkeley Lab’s Advanced Light Source could help scientists better understand and improve the materials required for high-performance lithium-ion batteries that power EVs and other applications. The technique, which uses soft X-ray spectroscopy, measures something never seen before: the migration of ions and electrons in an integrated, operating battery electrode. It was developed by a team of Berkeley Lab scientists including Wanli Yang (right) of the Advanced Light Source and Gao Liu (left) of the Environmental Energy Technologies Division. More>

Jeff Kortright and Walter Drisdell of the Materials Sciences Division led a study in which X-ray absorption spectroscopy at the Advanced Light Source was used to make the first in situ electronic structure observations of the adsorption of carbon dioxide inside Mg-MOF-74, an open metal site MOF that has emerged as one of the most promising strategies for capturing and storing greenhouse gases. Experimental results were recorded at ALS beamline 6.3.1. Computational resources at both NERSC and the Molecular Foundry were used to help interpret the data. Also working on this study, which was carried out through Berkeley’s Energy Frontier Research Center, were Roberta Poloni, Thomas McDonald, Jeffrey Long, Berend Smit, Jeffrey Neaton and David Prendergast.

The National Laboratories have a storied, yet largely hidden, history and presence in the energy innovation space. Created to build the atomic bomb in the 1940’s, the Labs have evolved to conduct “big science” to address leading national missions, solve complex societal problems, and keep the United States at the leading edge of innovation. In many ways, the Labs got their start on the backs of particle accelerators, particularly the cyclotron invented by Ernest Lawrence at Berkeley Lab. Today, Berkeley Lab houses one of the world’s premier cyclotrons — the Advanced Light Source — a domed, circular path of magnets that whip electrons around at nearly the speed of light. More>
A recent study led by Robert Ritchie of the Materials Sciences Division of the remarkably tough scales of Arapaima gigas, an air-breathing fish in the Amazon Basin that can swim with impunity through piranha-infested waters, generated a swell of media attention. Overlooked, however, was the critical role played by the Advanced Light Source’s beamline 7.3.3. Using SAXS imaging, Ritchie and his colleagues unlocked the secrets behind Arapaima’s natural dermal armor, which can stand-up to almost double the pressure of a U.S. nuclear submarine hull. Also working on this study were Marc Meyers, Elizabeth Zimmermann, Bernd Gludovatz, Eric Schaible, Neil Dave and Wen Yang. More>
Staff are invited to this month’s Advanced Light Source Science Café at noon on Friday, Nov. 1, in Bldg. 15-253. Speakers and topics include Marie Jackson (Roman Concrete), Greg Hura (DNA Labeled with Gold), and Dave Robin (Pseudo Single Bunch). The event will be moderated by ALS Director Roger Falcone. Light refreshments will be provided.
John Tainer, Life Sciences Division, and Greg Hura, Physical Biosciences Division, led the invention of a new technique for studying the process by which certain errors in the genetic code are detected and repaired. The technique is based on a combination of hybrid nanomaterials and small angle X-ray scattering (SAXS), which was performed at the SIBYLS beamline of the Advanced Light Source. It holds important implications for synthetic biology, microbial adaption and pathogenesis. Also contributing to this work were Chi-Lin Tsai, Shelley Claridge, Marc Mendilloc, Jessica Smith, Gareth Williams, Alexander Mastroianni, Paul Alivisatos, Christopher Putnam and Richard Kolodner.

Graphene may command the lion’s share of attention but it is not the only material generating buzz in the electronics world. Vanadium dioxide is one of the few known materials that acts like an insulator at low temperatures but like a metal at warmer temperatures starting around 67 degrees Celsius. This temperature-driven metal-insulator transition, the origin of which is still intensely debated, in principle can be induced by the application of an external electric field. That could yield faster and much more energy efficient electronic devices. More>
The ALS Users’ Meeting kicks off Monday, Oct. 7, in the Building 50 Auditorium with a full program of keynote speakers, poster sessions, workshops, and vendor exhibits. This year 31 vendors will be on hand to display a range of scientific equipment. To view this year’s roster of vendors, go the ALS User Meeting Exhibitors webpage. Employees are invited to visit the exhibits, on the patio and in the tent by the ALS, on Monday (10 a.m. to noon and 1:30 to 4:30 p.m.) and on Tuesday (9 a.m. to noon).
Using ALS Beamlines 10.3.2 and 8.3.2, the Environmental Protection Agency (EPA) is currently investigating how biochar sorbs environmental toxins and which kinds of biochar are the most effective. The possibilities for widespread use have already launched entrepreneurial commercial ventures. More>
All ALS and Berkeley Lab employees attending this year’s user meeting are urged to register for the event by Friday, Sept. 27. After that date, online registration will be closed. By registering now, meeting organizers will be able to have sufficient food and refreshments, and be able to coordinate workshop room assignments to reflect attendee numbers more effectively. In addition, long lines to register on the first day of the event will be avoided.
