Not sure I understand? If you have a 2D image showing powder rings then
you should have some very good ideas about the level of granularity or
textur
Dear Bhuv,
yes it is possible to evaluate it. Normally it should be sufficient to
compute the F2 index from the spherical harmonic coefficient.
The problem may be is that TOPAS does not have such computation inside.
So the other way is to export the coefficients, to hope they are some
standard o
Hi,
I would like to discuss a couple of questions raised by a referee;-(
I am not sure if it is ethical or not - I thought it is better to ask
the way than .

I have used very (very very)small amount of sample to collect a powder
pattern and I have corrected possible graininess with sphe
Hi
I think that is very difficult obtain a free-strain
material, and we can not neglect this effect, and it is very useful work
with integral breadth rahter tan FWHM, and you should use a reference material
in order to obtain the breadth due the instrument, because if you only take in

Dear users of the Rietveld method:
I would like to launch a question regarding the use
of the Scherrer method of line-broadening analysis. When estimating the crystallite
size in a undistorted material (free of lattice microstrains) using Scherrer
method, should I use the integral bread
P.S. The word "deposit" has additional meanings equivalent to
"sediment", "sludge", "settlings", "dreg", "varnish" etc.
Thanks. Just what I was meaning. The association "sludge varnish"
is even more accurate ? Sediment is fine because the Academy
