Why Austenite grains in steel show much more twinning than ferrite grains?

It is oftentimes said to be a distinctive metallographic trait that differentiates a fully austenitic and a fully felly ferritic steel without etching that might distinguish between two. Why...

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...

Why the results when using wall thickness and when using shell conduction are different in ansys fluent?

Actually, I am running cfd simulation for a heat exchanger which has two fluids one hot and other one is cold fluid. there is a solid domain between them, which I removed and instead I have used...

What is the most suitable server for predicting protein structures in bacteria?

I have used the i-Tasser several times, however it has been unavailable for several days. I tried the swiss-model, but the output was not very pleasant due to the model used. Is there any other...

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...

How do you mesh a thin solid in Fluent?

Hello, I have used the shell function on SpaceClaim to create thin solids for the model I am studying. These are contained within an enclosure for my study. I chose this approach as it avoids the...

XRD may work to identify your samples. If it was core-shell, XRD shows two groups of diffraction peaks from CdSe and CdS.

If the dots were very small---only a few nm---, the peaks become broad and hard to distinguish each peaks. But I think it's worth to try.

Thanks a lot Yoshiki

Dear Nitin,

You can go for multiphase powder profile refinement if you know the cell parameters of the two phases.
