On May 19, 2026, at 6:30 PM, the Biomaterial Design course organized an online Undip Global Classroom session. Moderated by the course lecturer, Prof. Dr. Tri Windarti, the event carried the theme “XRD Analysis and Diffraction Data Processing with MAUD Software.”
X-ray Diffraction (XRD) is an important instrument in biomaterial characterization. X-ray diffraction data contain extensive information regarding the crystallinity properties of materials when processed appropriately. One of the techniques used for XRD data processing is the Rietveld refinement method. Based on this method, various software programs have been continuously developed, one of which is MAUD.
On this occasion, the invited speaker was Limpat Nulandaya, Ph.D., from the Institute of Physics of the Czech Academy of Sciences. He has specialized in material analysis using diffraction methods for the past 11 years. According to his explanation, processing X-ray diffraction data using MAUD software can determine the types and compositions of compounds within a sample, crystal lattice parameters, crystal grain size, and even the atomic insertion positions within a crystal structure.
Crystallinity data are closely related to biomaterial properties, such as biocompatibility and bioactivity. This UGC event was attended by 63 participants consisting of students from the Department of Chemistry and the Department of Mechanical Engineering at Diponegoro University.
