Nacre–the iridescent inner lining of many mollusk shells– has a unique strcuture that is remarkably resistant to fracture. The nacre featured on this cover is from Haliotis laevigata with average layer thickness 470-nm. The colors represent crystal orientationthe crystal lattice tilts across tablets.left stack all tablets are yellow, hence all aragonite crystals are co-oriented. Read more »

ALS research has shown how the scales of a freshwater fish found in the Amazon Basin can literally re-orient themselves in real time to resist force, in essence creating an adaptable body armor. Read more »
A group of seventh graders from Black Pine Circle (BPC) school in Berkeley recently had a rare opportunity to experience the ALS as “users” via a scientific research proposal project and field trip. The students were led by science and technology teacher Christine Mytko, who spent the past summer at the ALS through the Industry Initiatives for Science and Math Education (IISME) program.

In his 19 years at the ALS, senior scientist Musa Ahmed has seen chemistry grow from a somewhat obscure synchrotron science focus area to a cornerstone, award-winning ALS program. Ahmed was recently charged with leading the chemical sciences program for both ALS chemical dynamics beamlines, 9.0.1 and 11.0.2, which befits his long-standing enthusiasm and leadership in advancing chemistry research at the ALS.

“Safety is elemental” is the latest safety tagline for the ALS and Berkeley Lab, and it also pretty much sums up the mission of laser safety officers Greta Toncheva and Robert Fairchild. Toncheva and Fairchild share the responsibility of ensuring laser safety lab-wide, with Toncheva responsible for overseeing laser safety operations at the ALS. Read more »
New insights into the ancient Romans’ ingenious concrete harbor structures emerging from ALS beamline research could move the modern concrete industry toward its goal of a reduced carbon footprint.
Analyses of ancient concrete samples pinpointed why the best Roman concrete was superior to most modern concrete in durability, why its manufacture was less environmentally damaging, and how these improvements could be adopted in the modern world. Read more »
Using ALS tomography capabilities, the EPA is currently investigating how biochar, a promising biofuel byproduct, sorbs environmental toxins and which kinds of biochar are the most effective. The possibilities for widespread use have already launched entrepreneurial commercial ventures.

Using angle-resolved photoemission spectroscopy (ARPES), researchers have shown that the number of conduction electrons in anatase, as well as their degree of correlation, can be patterned by exposure to UV light in a controllable and reversible way. Read more »
TE Connectivity designs and manufactures more than 500,000 different electronic connectivity products for the automotive, energy, industrial, broadband communications, consumer device, healthcare, aerospace, and defense industries. TE has been investigating how ALS tomography capabilities can help the company develop more efficient connectors.
