What is optimal electron accelerating voltage for TEM measurments of polystyrene nanoplastic? (200-300kV - would be too high?) I found in literature most PSNP studies with ~100kV.
I would go with 80 kV - 120 kV.
Does anybody know how to convert IU/ml in case of anti-TSHR antibodies (Graves disease)? I would like to know how much anti-TSHR Ab I have in a sample

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...
