What is the contact angle of a glass coverslip?

17 April 2017 1 7K Report

I keep getting different contact angles for my glass coverslips (tested on different days). I would like to know if anyone knows what the actual scientifically determined contact angle of a glass coverslip is so that I can corroborate my results.

Carlos Araújo Queiroz

For water, the contact angle noticeably depends on surface activation, conditioning, drying, or cleaning methods; that might have been applied. Cf. (e.g.): http://pubs.rsc.org/en/Content/ArticleLanding/2004/CP/b308125g#!divAbstract

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 don't d-orbitals split themselves, why does it take a ligand? why don't protons from ligand repel nucleus split d-orbitals?

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...
