Nanoscale chemical imaging with structured X-ray illumination

What is it about?

High-resolution imaging with compositional and chemical sensitivity is crucial for various scientific and engineering disciplines. Based on structured illumination with sandpapers, we develop a new X-ray imaging approach coupled with a generative AI model for mapping the compositional heterogeneity with nanoscale resolvability.

Why is it important?

High-resolution imaging that can reveal chemical details is vital across numerous scientific fields. We utilize structured illumination to create a unique X-ray chemical imaging technique. It allows for detailed mapping at a nanoscale without needing highly focused X-rays or slow scanning processes. By applying this to a battery sample, we showcased its potential to unveil intricate compositional differences. This technique has broad implications, offering advanced imaging solutions in biology, environmental studies, and materials science, and is especially beneficial for samples sensitive to radiation.
