1. If I can quantize the atom using this hyperbolic spiral and classical physics, could nature do the same?

If we map as a continuous motion an ionising electron (beginning its journey at n=1) in an H atom, a specific hyperbolic spiral appears (see animation). When we solve this spiral formula, we find...

They are aggregated from the drying process,

Kholoud Seferji

Thank you,,

Do you have any suggestions to prevent this problem

Do not dry them, keep them in suspension

Because I prepared it in ethanol water soloution

Do you think there is overlapping in the peaks because before the lyphilization the uv absorbance was at 400 and the TEM images show clearly the nanoparticles before and after the lifilization
