Can we say fullerene, CNT, graphene are Quantum dots, quantum wire and quantum well respectively?

Semiconducting nanoparticles can be classified as QDs, Q wires and Q wells. I have doubt whether this quantum confinement is only in semiconductors. Is this aclassification based on confinement is...

How do we index the ZnS and CdS Quantum dot crystal planes spacing from high magnification HRTEM images?

Crystal lattice planes are observable in HRTEM images and we can find the lattice plane spacing. My confusion is how we index the crystal planes as (100) ,(111) etc. How we make sure observed...

How Relativistic effects is one reason for lanthanide contraction?

The Lanthanide contraction which is the decrease in ionic radii of the elements in the lanthanide series from atomic number 57, lanthanum, to 71, lutetium, is due to poor shielding of the 4f...

Is there a deep reason for using the squared modulus of the wave function as the probability density of the existence of the particle?

I think we were all surprised at the first time we got to know quantum mechanics that the squared modulus of the wave function is the probability density of the existence of the particle? The role...

What could be the reason for not having further low chi square value (better agreement) in my refinement result?

I have tried every combination of parameter changes and after that i have a poor chi square value. I can't get it lower any further. I know there have been a lot of discussion about Rietveld...

How to replicate the well conditions of a crystal hit with 20%(w/v) isopropanol?

I had a crystal hit in a well with 0.1M HEPEs pH 7.5, 10%(w/v) PEG 4000, and 20%(w/v) isopropanol. Why is isopropanol in w/v here if it's just solvent? How do I recreate this well condition?
