What is the Potential of Solid State Heavy Water in Concrete and Starches?

AI Thread Summary
Recent discussions highlight the discovery of solid state D2O (heavy water) in materials such as concrete, starches, and cellulose at standard temperature and pressure (STP). The implications and potential applications of this finding remain unclear. Some participants question the novelty of the discovery, suggesting it may relate to existing research on amorphous hydrogen-bonded networks surrounding hydroxyl groups. Clarification is sought on whether this research presents new insights or simply reiterates known phenomena. Further details from the peer mentor are anticipated to better understand the significance of this work.

This isn't so much a question, just something I thought was interesting. I met with my peer mentor last week and she's doing research which has lead to the discovery of solid state D_{2}O in concrete, starches, and cellulose (all at STP). She's not sure where this is going to lead or what applications this will have, if any, but I just thought it was strange. Has anyone heard of any other research on this type of thing? I'm curious to hear some thoughts on where this might go, or whether or not this has type of research has been done before.

EDIT: I don't know why, but the LATEX subscripts haven't been working for me. I figure everyone should understand what I mean since it's in the title, but the D2O I was referring to is heavy water.

Define 'solid state'. You mean amorphous hydrogen-bonded networks around the hydroxyl groups, etc? IOW: A kind of 'ice' around the macromolecules? I don't quite see what'd be news about that?

What exactly are they claiming to have discovered?

(And how is it different from, e.g.: http://dx.doi.org/10.1016/S0921-4526(98)01497-5" )

From what I can tell, it's amorphous H-bonds forming around the OH groups. Also, I may have made a mistake when I said discovery. I'm not sure whether they're claiming what they're working on is anything new, but I hadn't heard of this before, although I'm by no means well read in recent chemistry research. My peer mentor did a sort of graduation project on this, and I'm not sure whether it had to be necessarily ground breaking, which after looking at your link, it seems this isn't. I'll ask her for more details, as I only talked to her briefly about it.
 
It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
