Why cells are not adhering and detaching?

I have cultured podocytes in the T75 flasks and 100x15 plates and used same medium for both. The plates are doing great; however in the flasks cells are not adhering well and detaching. What might...

How do I conformally do PR spin coating on trench structure?

I did PR spin coating on trench structure. I used AZ P4620 PR and the thickness or PR is around 11um. The substrate is Si. And my trench structure depth is 141um(negative way). Even though I...

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...

Why reactivity isn't increased with more empty spots in valence shell?

If from a geometric perspective the non-halogens, non-noble gases have more empty spots in their valence shell, and the filling/exiting of any of the empty spots in the shell constitutes a...

Why doesn't chromium 2+ ion use all its d-orbitals to receive lone pairs from six waters in [Cr(H20)6)]3+?

I'm guessing it's because the ligand experiences too much electron repulsion or proton repulsion from the chromium to insert them close to the 3d-orbitals which are close to the metal nucleus. Is...

Dhrubajyoti Bhattacharjya

the starting point of nyquist plot is generally called ESR.

Bapi Bera

Actually whoever doing EIS (Electrochemical impedance spectroscopy), they are often used ESR (Equivalent series resistance) and familiar with ESR.

Where the Nyquist plot start (intersection to X-axis ) is called ESR.

Jennet Rabo

thank you! I think ESR is the diameter of the semicircle in the Nyquist plot?

Ramesh Oraon

ESR is the total resistance contributed by charge transfer, solution resistance and contact resistance.
