90% C-Se-C

This study examines the distribution of Selenium (Se) and Calcium (Ca) in the petals, pistil, stamen, and seed pod of A. bisulcatus flower using µXRF mapping and XANES analysis. The composition of Se in various floral parts is determined. Circles in the maps indicate where XANES scans were conducted.
