What happens to RG contributions of a member upon his or her demise?

I was involved in this RG discussion and came up with this scenario: https://www.researchgate.net/post/Why_wustite_FeO_and_nitride_FeN_have_same_picks_in_GI_XRD?view=5a6ea20e5b4952dd7a765a23 One...

How do I figure out the film thickness of the individual layer spatially from these diffractograms?

We've looked at an epitaxial film of GaN on a Si substrate using real time 2D Bragg XRD Microscopy (2D XRD rocking curve analysis). This specimen also had intermediate "buffer" layers of AlxGa1-xN...

What is the best method used to align the diffractometer plane/axis with respect to the incident beam direction?

Most of the XRD community is presently using 0D point counter or 1D linear PSD (position sensitive detector) in powder diffraction as well as rocking curve analyses. Any mention of the extinct...

Is this a reasonable way to convert experimental multi-dimensional XRD data of the reciprocal space into meaningful Nanostructural parameters?

Nano structural meaning to 3D XRD data: Converting the Bragg condition to crystallographic distortions and lattice strain fields topographically. The objective of any materials characterization...

Can XRR (X-Ray Reflectivity) be implemented in the Topographic Mode with spatial resolution over the sample surface? Is there value for such analyses?

Conventionally XRR, X-Ray Reflectivity, measurements have been conducted using a point or line source but always using the 0D point/scintillation/proportional type detector without spatial...

Would anyone have a clue as to the origin of "unexpected spots" in the real time 2D XRR signal from thin film samples on substrates? Yoneda Spots?

X-ray reflectivity (XRR) is a technique abundantly used and vetted, for determining film thicknesses and "flatness" of thin film samples on substrates, over the past century. We have implemented...
