Planes of graphite crystal on diffraction experiments
When doing electron diffraction on graphite (a popular experiment for students at universities) always diffraction at these two planes with distances $d_1$ and $d_2$ are observed:
But a plane ...

Algorithm for identifying planes in a Bravais Lattice
I have a lattice with Lattice Vectors $(\vec{t}_1,\vec{t}_2,\vec{t}_3)$ which are NOT orthogonal in general.
How can I identify the atoms/unit cells that belong to a plane - that is normal to a given ...

Software for Rietveld Analysis [closed]
If I want to do Rietveld analysis, which software would you suggest?
I already tried FullProf, but I find it quite confusing and not user friendly.

X-ray diffraction (is it possible?)
Is it possible to extract full lattice structure of a crystal from any of X-ray diffraction methods? (especially that the diffraction pattern is 2-Dimensional most of times)

How are X-rays focused? Specifically in XRD. Well do they even focus X-rays in XRD?
I read in a government website that reflecting an x-ray from a parabolic mirror followed by a reflection from a hyperbolic mirror results in focusing the x-ray, but this was for astronomical purposes. ...

Is the index of refraction dependent on the wavelength of light?
I just read in some class notes for a crystallography class that there are no refractive lenses for X-rays because the index of refraction of most materials is close to 1. Is the index of refraction ...

How can I cheat an XRD sample (~10 mg) from a total 1g required? How can I use for the background.
How much can affect (in terms of hump) my X-ray diffraction pattern the "amorphous" glass or maybe someone can suggest me other material to compensate for the small amount of the sample.
Note: my ...

X-Ray crystallography using Bragg's Law
I was looking up X-Ray crystallography using Bragg's Law:
$2d\sin\theta = n\lambda$
and I can understand the values of everything except this integer value $n$.
As far as my research got $n$ is ...
