COSMIC-Coherent Scattering and Microscopy
Used to measure the material properties at Nano scale
This allows scientist to investigate batteries and other active chemical reactions, and to reveal new details about magnetism and correlated electronic materials.
X-ray imaging experiments
In both cases X-Rays react with sample and gives structural, chemical, electronic, or magnetic information about samples.
Ptychographic computed tomography :
This mapped the location of reactions inside lithium-ion batteries in 3-D.
Ptychography achieves spatial resolution finer than the X-ray spot size by phase retrieval from coherent diffraction data.
This allowed them to view the chemical states within individual nanoparticles.
Researchers looked at a piece of a battery cathode in 3-D with a resolution that was unprecedented for X-rays.
This provides new insight into battery performance both at the single-particle level and across statistically significant portions of a battery cathode.
COSMIC is focused on a range of “soft” or low-energy X-rays that are particularly well-suited for analysis of chemical composition within materials.This can be focused upto 50nm.
The current detector can operate at a data rate of up to 400 megabytes per second and can now generate a few terabytes of data per day enough to store about 500 to 1,000 feature-length movies.
Next-generation detectors, to be tested shortly, will produce data 100 times faster.
Scientists have already used COSMIC’s imaging capabilities to explore a range of nanomaterials, battery anode and cathode materials, cements, glasses, and magnetic thin films.
