Why neutron diffraction is more powerful than XRD in detecting order- disorder transitions in solids?

I have stabilized tetragonal phase of solid electrolyte at room temperature and this phase is fully ordered at RT. But it is found to be disordered tetragonal beyond ~450 deg. C. this order-...

Is it correct to compare the values of σg and σgb for different x when the thickness of the samples can differ?

I prepared an oxide- ion conductor with varying dopant content (x). AC impedance spectra were recorded for all samples whose pellet thicknesses were different. From the parameters extracted by...

Has anyone ever seen a research paper showing correlation between crystal vacancy concentration and photocatalytic efficiency of a photocatalyst?

I have prepared a ternary metal oxide, Bi2V1-xMnxO5.5-x as a photocatalyst and investigated the variation of its photocatalytic efficiency for degradation of azo dye as a function of dopant...

Does anyone know a valid equation that correlates the crystallite size with crystal lattice dimensions?

I want to show the influence of changes in unit cell parameters as a function of dopant concentration on the crystallite size changes. I therefore need an excellent equation that correlates the...

When would the temperature dependence of conductivity and the segmental relaxation for a polymer electrolyte result in similar activation energies?

In past studied have polymer electrolytes have ever shown that temperature dependence of conductivity and the segmental relaxation would result in similar activation energies? That would support...
