Andi Jones joined the ALS User Services Office as proposal coordinator last April and has taken over the processing and tracking of General User, RAPIDD, and Approved Program proposals. She also maintains the ALS publications database and serves as a point of contact for users who have beamtime or proposal questions. ... Read more »

Developing ceramic matrix composites (CMCs) to replace the metal alloys traditionally used in jet engines has been a goal for the aviation industry for decades. For more than a year, GE Aviation has used the tomography capabilities at ALS Beamline 8.3.2 to gain insight into their CMC materials, guiding their engineering and design efforts. ... Read more »
Electrochemical (battery) cells with aqueous electrolytes can be safe, inexpensive, and environmentally friendly, but they are limited by a narrow voltage window. X-ray absorption spectroscopy helps explain why an aqueous Na-ion system with Mn5O8 electrodes has a large voltage window and performs comparably to Li-ion batteries. ... Read more »
Superhard materials such as metal borides are in demand as structural and engineering compounds and for next-generation cutting tools. Researchers have now synthesized a “solid solution” of two different metal borides, demonstrating the accuracy of theoretical predictions and opening the door to more targeted tuning of desirable characteristics. ...

A powerful soft x-ray microscope captures tomographic images of the genetic material in the nuclei of nerve cells at different stages of maturity. The detailed 3D visualizations show an unexpected connectivity in the genetic material and provide a new understanding of a cell’s evolving architecture.

Scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and NASA are using x-rays to explore, via 3D visualizations, how the microscopic structures of spacecraft heat shield and parachute materials survive extreme temperatures and pressures, including simulated atmospheric entry conditions on Mars. ...

The use of DNA for nanotechnology has gained interest because it is a highly “programmable” polymer with “sticky ends,” allowing the self-assembly of molecular scaffolds for other proteins and molecules. Their high-resolution structures will help map new routes toward the rational design of self-assembling 3D DNA crystals. ... Read more »
Soft x-ray ptychography was used to measure the absorption and refraction of x-rays through pristine reference materials as a basis for decomposing spatially resolved spectra from a heterogeneous sample, thereby quantifying the composition at high resolution. The novel method provided a nearly five-fold improvement in spatial resolution on resonance. ... Read more »
Visiting scientists met Jan. 18-20 at Berkeley Lab for a workshop that collected input on the range of new science that will be enabled by the planned upgrade of the Lab’s Advanced Light Source. The upgrade project, known as ALS-U, will boost the brightness, focus, and other properties of the light beams produced at the ALS. ... Read more »
