Intensity is measured in W/cm^2 , NOT in J/cm^2 ! — Preceding unsigned comment added by 62.141.169.250 (talk • contribs) 09:29, 7 March 2011 (UTC)
Youtube
[edit]There is a video on Youtube, released 2013, that shows and explains a Coulomb explosion generated by placing alkali metal into water. I believe it should be included in the references because it predates existing references, however I do not know how to cite a Youtube video as a reference.

Mechanism
[edit]What is the physics mechanism that causes the explosion? Woofwoofwooof (talk) 15:07, 29 December 2019 (UTC)
Not a good enough explanation for sodium in water
[edit]Adding a small amount of pure sodium to pure water in standard atmosphere causes burning (of hydrogen) then a loud bang of an explosion.
Researchers have recently seen that the sodium emits a dense array of spherically symmetric "fingers", presumably of ionic sodium liquid, at about 200 nanoseconds elapsed time. This accounts for the intimate interface required for an explosion, but does not prove that the explosion is completely Coulombic (that an electric discharge occurs among the sodium ions, dispersing them energetically at the atomic level). The actual explosion could be caused by mechanical expansion due to the high exothermic reaction temperature, or even (less likely) the fast burning of hydrogen along the fingers.
The article is clearly wrong, in the sense of being either incomplete or speculative, as it currently stands. David Spector (talk) 18:11, 29 January 2020 (UTC)
Nuclear Plasma Explosion From Nuclear Fusion Reactor
[edit]I would like to know more about a nuclear plasma explosion. If someone does try to produce nuclear fusion reactor with plasma if it goes wrong, what might happen? — Preceding unsigned comment added by 81.106.29.7 (talk) 00:45, 22 February 2021 (UTC)
Cnidaria does not use Coulomb explosions
[edit]The cited reference does not support this example’s conclusion:
” Thus, the equilibration of the proton concentration initially results in a negative net charge within the cyst and therefore in a sudden electrostatic repulsion between the dissociated carboxyl groups of the polymer. This causes an increase in the pressure of the matrix against the cyst wall.”
This describes simple electrostatic repulsion in a fluid, which is extremely common in biochemistry. My understanding of this topic is it refers specifically to the repulsion of nuclei after electrons are irradiated away; no such process is occurring in Cnidaria.
I would make the edit but I am not a regular Wikipedian and defer to anyone who is watching or maintaining this page. 99.45.168.6 (talk) 21:38, 28 July 2024 (UTC)
