Curious about pentawater or polywater edit

I'm curious, is the phenomena mentioned in this article analogous to pentawater or polywater, if not how is it significantly different? Are the computer simulations (the definition of in silico) meant to be representations of the structure of liquid water under ambient conditions, if so, why then is a liquid helium environment needed, for the scanning tunneling IR spectrometer, to visualize the structures? 76.254.195.78 (talk) 14:02, 12 March 2008 (UTC)Reply

  • this article has nothing to do with either pentawater or polywater, linking from here to these pages would be a disservice to the legitimate research presented here. The only way to observe clusters experimentally is by trapping them in liquid helium. V8rik (talk) 18:47, 12 March 2008 (UTC)Reply

I think that there is a greater risk that this article adds credibility to various pseudoscientific claims made by bottled water or point-of-use water treatment system manufacturers around the health benefits of water clusters.

Someone coming across marketing claims about water clusters is likely to look up this article, and may conclude that water clusters are real hence the marketing claims are credible.

I propose that a section on pseudoscience which can distance legitimate research from unproven marketing claims would better serve both the water cluster research community, and the general public. DrJock (talk) 13:42, 11 July 2022 (UTC)Reply

That might be true. Are you interested in drafting something? Qflib, aka KeeYou Flib (talk) 13:29, 12 July 2022 (UTC)Reply

Thanks @Qflib yes, I'd be happy to, thought I'd better check here first since @V8rik was concerned it could be a disservice to the legitimate research. If nobody objects before I get time I'll try to draft something sensitive. DrJock (talk) 22:18, 16 July 2022 (UTC)Reply

I’m also very concerned about that, but the devil is in the details. If you want to draft something in your sandbox and have me take a look at it, be glad to help. Qflib, aka KeeYou Flib (talk) 22:52, 16 July 2022 (UTC)Reply

Water Vapour at thermodynamic equilibrium edit

Would i be correct in thinking that water clusters have a large bearing upon the thermodynamic equilibrium of Air(a non-ideal gas). And that it is a desire of water to reach minimal energy states that is largely determining thermodynamic equilibrium. If this is the case, is there a consensus as to the most common water cluster structure within Air at thermodynamic equilibrium. 79.76.221.242 (talk) 14:56, 21 October 2009 (UTC)Reply

Too much value given to Wikipedia problem list edit

So little is understood about water clusters in bulk water that it is considered one of the unsolved problems in chemistry.

You mean according to the Wikipedia ad-hoc list !!! 89.217.31.142 (talk) 22:08, 12 January 2015 (UTC)Reply

In-silico? edit

'In vitro' and 'in vivo' are relatively well known terms for experimental conditions but 'in-silico' is, I suspect, a somewhat tongue-in-cheek neologism that adds no value to the text apart from an air of mystery and the need to click on the link to find out what it means. I suggest that we change it to 'computer-modelled' or similar. Martin Hogbin (talk) 12:46, 4 December 2015 (UTC)Reply

Visual observations by Shu et al. edit

The microscope observations by Shu et al. seem to be very amateurishs and seem very questionable from theoretical considerations:

Shu et al. reported the images of water clusters of 100 micrometres.[1][2]
Shu et al. observed water clusters under microscope. The experiments were conducted in two ways. One is making sodium chloride solutions and sampling water clusters from the solution, then putting the solution with water clusters on a glass slide under a microscope. The second method is putting a drop of ultrapure water on a glass slide under a microscope and putting a grain of salt next to the water drop, then pushing the salt grain inside the water drop. Under the microscope, salt starts to dissolve and break into smaller salt particles. Some of the salt particles enter water clusters and reveal the appearance of those clusters.

I do not have access to the source papers. Could someone please check them? Thanks... --Jorge Stolfi (talk) 21:31, 1 March 2020 (UTC)Reply
