In the amorphous to crystalline transition of particles with the presence of organics, how can one detect the trapped organics inside the particles?

Through characterization processes like XPS for instance, we can understand if there are absorbed organics to the outer surface of the particles even we can know from which moieties they are...

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...
