Question
Chapter 21, Problem 21.10QAP
Interpretation Introduction
Interpretation:
The definition for the buried interface and the techniques available to study buried interfacial phenomena are to be stated.
Concept introduction:
The buried interfaces are those interface which are embedded under the surface in the layered structures. These types of interfaces are not present on the surfaces but present below the surfaces.

What differs an amorphous polymer from a crystalline one?
I) Diamond crystallises in a face-centred cubic structure with a = 3.5625 Å. Calculate the d-spacing and peak position of the first allowed peak (i.e. the peak with the lowest hkl value that meets the selection rules) using a wavelength of 0.71073 Å.
II) A solvothermal synthesis gave rise to a mixture of two crystalline phases: one phase consists of 50-65 μm octahedral crystallites while the other phase consists of 150-180 μm hexagonal plates. Identify a separation technique that would likely be effective in separating these materials.
