Question 1.
What does XRD stand for?
Show hintHide hint
Think about the process of analyzing materials using X-rays.
Question 2.
Name one application of XRD.
Show hintHide hint
Consider what XRD helps to determine in solid materials.
3Question 3.
What does the Scherrer equation estimate?
- Crystal structure
- Crystallite size
- Phase identification
Show hintHide hint
What aspect of the diffraction peaks does it relate to?
4Question 4.
True or False: XRD is only used to determine crystal purities.
- True
- False
Show hintHide hint
Consider the broader applications of XRD.
Question 5.
You are analyzing a new nanomaterial using XRD and observe multiple unexpected peaks along with the main peak in your diffraction pattern. How would you interpret these results?
Show hintHide hint
Consider what unexpected peaks typically indicate.
Question 6.
A researcher is trying to optimize a catalyst by controlling its crystallite size using XRD measurements. They notice the peaks are becoming broader. What does this mean in terms of crystallite size?
Show hintHide hint
Reflect on the relationship between peak width and crystallite size.
