How do we calculate the exact composition (formula) of a perovskite material synthesized by mechanochemical method?

After the mechanochemical synthesis of a novel perovskite, though we take its PXRD to see the phase still we are not sure about the exact ratios of all cations and anions. How to calculate them?

Could anyone please tell me how to make pictures of MOFs incorporating other species?

I am working on Polyoxometalates (POMs) based metal organic framewoks (MOFs). I want to make some diagrams in which POMs are incorporated/encapsulated inside pores of MOFs. I have attached...

Why the redox peaks of a MOFs are silent in a POM MOF composite?

when we scan the electrochemical behavior of a mof its redox peaks are visible but when they make a composite with some material like Polyoxometalate, then in cyclic voltammogram of this composite...

Can we immobilize trilacunary POM like PW9 or AsW9 etc on MOF?

WE all know that POM could be immobilized by incorporating them in pores of MOFs? Could we do the same thing with the substituted POM or lacunary poms also? Please suggest some readings.

How can I find out the purity and particle size quantitatively from PXRD data?

From the sharpness of peak we conclude whether it is amorphous or crystalline and from the appearance of extra peaks impurities are suggested. But these suggestions are qualitative. Could we...

How can I know about the anion in MOF structure?

SXRD does not show anion or counter ion in its structure. How would we know that which counter ion is attached at outer sphere to balance to positive charge of the metal ion because in some cases...

Is "Encapsulation of Polyoxometalates in MOFs" and "composites of polyoxometalates with MOF" different or same?

If the pore size of MOF is smaller than the POM size then encapsulation is impossible. But is their any chance of adsorption of POM on the surface of MOF making a composite?
