Module 2 : Structure analysis tools

Lecture 3 : Powder diffraction

Quiz 3:

(Q3.1). What are the information can be obtained from typical XRD patterns?

(Q3.2). How does d-spacing vary with increasing diffraction angle for a particular crystal structure?

(Q3.3). Is it possible to understand the alloying of two elements from XRD pattern? If yes, How do you understand?

(Q3.4). How does uniform and non-uniform strain affect the XRD peak?

(Q3.5). How do we quantify the fraction of nanocrystals grown out of amorphous matrix?
