2022 2nd Mini-Test

1. Predict the birefriengence of calcite, and compare with experiments.

2. Try to assess how to distinguish Rutile and Anatase phases of powder TiO2.

3. The magnetic moment of Fe is larger than that of Ni, is that due to element or structure ? Design a computational study to prove your point.

4. Is it feasiable to use spectroscopic tool to distinguish real from fake (USSR, ZrO2) diamond ? Suggest your instrument and simulate.
