How we can measure thickness for thin film by using UV Visible Spectroscopy?

Using UV Vis, we can measure easily masure thickness but how? It has some formula which is quite complex for non-mathematician and I hope there will be some researchers how to do it.

Is that possible not to carrying out heating process after spraying glass slide with silane solution?

Most of the papers that I read carried out heating process ranging from 100 - 200 degrees within few hours. Can we skip this step so that practical application will be much easier?

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...

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...
