Any simple method to calculate the lattice parameters of a crystal lattice of a known configuration (i.e. orthorhombic) from XRD spectra?

Several of the methods to do this are explained in a rather involved way; could somebody simplify / give us a basic idea of how to use these methods and how they work? P.S. Please don't say...

Is there a simple lattice matching algorithm one may follow to choose candidate substrates for epitaxial growth?

It is my understanding that this may be done by comparing unit cells between the substrate and the material to be grown, but I would want to delve into the details as to how this lattice matching...

Can anyone suggest a smart way to calculate volume fraction of a solid ferrofluid in a solvent or 'solids fraction'?

If for instance, I had a solution of 50 mg solid ferrofluid/mL solvent, how can I use this information to find its corresponding volume fraction? I had no luck finding an adequate relation in the...

Is there any analytical expression that can be used to determine the viscosity of a mixture of two or more miscible oils?

If the two oils can be mixed uniformly, will the new viscosity be an average of the two? Will the relation be linear? non-linear?
