After a first-year ramp-up for testing and tuning components, COSMIC is now operating at the ALS. The beamline brings together unique capabilities to measure the properties of materials at the nanoscale, and scientific results from its earliest experiments are expected to be published later this year.

Ptychography of a Bacterium’s Inner Compass
Magnetotactic bacteria (MTB) synthesize chains of magnetic nanocrystals (magnetosomes) that interact with the Earth’s magnetic field like an inner compass needle, simplifying their search for optimum environments. Ptychographic spectra of magnetosomes from a marine MTB provides insight into how these inner compasses form. Read more »
2015 Director’s Awards
ALS staff took top honors in Lawrence Berkeley National Lab’s 2015 Director’s Awards for Exceptional Achievement and were recognized in a ceremony earlier this month. The ALS recipients comprised nearly half of this year’s awardees, receiving recognition in the scientific, early scientific career, and safety categories. The Director’s Awards honor individuals in both the scientific and operations divisions forRead More Read more »
X-Ray Microscopy Reveals How Crystal Mechanics Drive Battery Performance
Recent findings at the ALS show that small crystal size is key to maintaining a battery’s performance and establish soft x-ray ptychography as an essential tool for studying chemical states in nanoparticles.

Record-Setting Microscopy Illuminates Energy Storage Materials
Using soft x-ray ptychography, researchers at the ALS have demonstrated the highest-resolution x-ray microscopy ever achieved by imaging five-nanometer structures. The researchers used ptychographic imaging to map the chemical composition of lithium iron phosphate nanocrystals, yielding important new insights into a material of high interest for electrochemical energy storage.
