Is X-Ray-Emission-Containing Phosphorescence possible or is it limited to Immediate-Emission XRF?
This was a random thought that I wanted to follow up on. I know some materials can take in and kick out X-Rays in XRF (Though most x-ray scintillators tend to emit mostly visible light, not x-rays). ...

How can we calculate entropy produced by plastic deformation in this example?
Suppose we have a massless spring of spring constant $k$ attached to a mass $m$ at equilibrium position $x_{0}$ at temperature $T$. The mass may oscillate in one dimension only for simplicity. We ...

Could a transparent frequency-altering material be possible?
I would imagine a material that is transparent but a electromagnetic wave going out will have a lower frequency than when going in (and maintaining it's direction). You could build glasses to see UV-...
