any suggestion for where one may ask for ideas for an Original Research Proposal (i.e. thesis topic) for a Ph.D.? I'm thinking maybe the Academia SE, but really it seems like an opinion-based thing so it may just be a thing for chat only.
I'm still in the throes of getting a main project worth working on for a few years.
I'm a computational chemist that works mainly with material / interface simulation. Usually with classical models/force-fields.
Advisors have some input but a fresh opinion would be appreciable.
The guidance for newer users is awesome, and probably even sometimes redundant. However, as soon as you get past some arbitrary rep threshold, especially on smaller sites, there's this huge learning curve when you want to learn more about the system, in other words look around a bit.
A good port...
@hBy2Py there's a good chance the question up there will not be received well, and I can't think of examples of the top of my head. So you should respond to Oded's comment up there if you want to save it, in a way
@Fl.pf. the tagging system is not meant to be used to indicate the quality of questions, there is a closure policy in place for that and we already use it liberally

If I succeed, can I ask you a question about energy decomp analysis? I get the feeling you've mentioned it before in some of your answers, so I thought you'd be a good person to ask.

I am looking to use the absorbent material found in nappies to improve the water retention of the soil in my garden.
To this end, I have two questions that I have not found definitive answers too.
Are disposable nappies made with Sodium or Potassium Polyacrylate?

Can someone provide reliable data on the solvation / hydration enthalpies of $\ce{Ti^{4+}}$ and $\ce{Cr^{3+}}$ ions, or explain which is more stable qualitatively? According to this article
CFSE in $\ce{Cr^{3+}}$ is around 59.7 kcal = 249.7848 kJ
and according to the abstract here the estimate...
@mhchem Well you know, I tried that first, found out it worked and was happy. I didn’t want to put anything aside from εffort into that edit so no going back and re-checking ;) But I’ll keep it in mind for further edits.
@BountyHunter It hurts to see all those extraneous curvy brackets in the mhchem syntax .__. And the missing MathJax at $\pu{59.7 kcal} = \pu{249.7848 kJ}$ .___.
I had a look at the list of room owners and found out that @M.A.R. is essentially alone there. I was looking at someone to promote for some time now, and you are a good candidate since you are here often.
> It is a curious thing, Harry, but perhaps those who are best suited to power are those who have never sought it. Those who, like you, have leadership thrust upon them, and take up the mantle because they must, and find to their own surprise that they wear it well.
@Jan The revision history tells me that you replaced 0.01mol dm^{^-3} with \pu{0.01mol\,dm^{-3}}, so you replaced the space with \,. And my point is that you don't need to.

Yeah, Community-Wiki probably is a good solution for a lot of those. Anyway, thx for the good question and ideas! — airhuff9 mins ago
I have a fan, huh
@hBy2Py You can ask me
Oh crap, I never realized I earned a reversal for that headache.
@hBy2Py Reversals in meta.SE are handed out like chocolate
All you need to do is wait for a drama about private messaging or comments requiring downvotes, and having been around enough to quickly write a good response with a few links as a slap to the OP's face and if you get lucky, you get a reversal.
I can provide you with screenshots, since that post was deleted but it was my post
There's this Supernova user. I really don't like their avatar and I want to downvote everything they say. I don't care that's not a valid reason for voting and votes should only be on the content, not the user. The votes are all anonymous, so I should be fine, right?
Oh shucks. I lose 1 WHOLE re...
The title just it, I really don't know if someone else has posted the same thing, but just keen to know, I mean if we feel an answer is no good, shouldn't we be given the freedom to down vote it at no cost?
Just asking, since i am kind of hunting my first gold badge, if i put up a bounty on a question with an already accepted answer, will it gain me more views?
@Hexa @hBy2Py @Ortho @Penta @Mart @Others when should/can we hold the event to burn [homework] and [reaction]? Please ping me with times of the day you're willing to participate
I would prefer if we held back on killing homework for the time being.
Sorry
I want to think a bit about what Jan wrote on my post.
I don't think we need to figure out an entirely new HW policy, however I think we need to figure out what cleaning up entails.
That said, you can sign me up for reaction. It's holidays now and I am free the whole day (UTC+1), obviously I cannot dedicate the whole day as I need to study, but I will be able to put aside time for this at any point in the day.
I agree. I am thinking of something simple along the lines of, if it has a good answer -> improve the question (and reopen if necessary); if it does not, delete.
Gases at STP
For the following reaction:
N2(g) +3H2 (g) 2NH3(g)
a. What volume of nitrogen gas at STP would be required to react with .334 mol of hydrogen gas?
b. What volume of nitrogen gas at STP would be required to react with 1.87 g of hydrogen gas to produce ammonia (NH3)?

@hBy2Py It is ok. Different timezones can be a hindrance, but can also be a help (it works out very nicely for the mod team, as we have people round the clock).
@M.A.R. Perhaps the best thing about the first question I linked, is that the asker did not list the most important reagent (hydroxylamine hydrochloride).
@M.A.R. I am probably not going to be able to commit to a time, I've been swamped for months and will continue to be swamped for months...not even a bounty on a question up my alley can save me :(
But if I see something "happening" and I'm awake I might try and help.
@orthocresol We should do a Google Sheet for scheduling -- half-hour UTC increments across the columns, and each potential participant can add a row for their availability -- shade the cells where they're available.
Whichever slot(s) has/have the best coverage we can choose those.
I expect to be swamped by work in a few months' time. (Probably roughly when we might have another election.) So, exploit my relative freedom while you still can.
It seems status-bydesign that HTML entities are not parsed in chat. What's the rationale for this?
In my humble opinion, HTML entities can be very useful. I would be able to freely type "—" with — and "–" with – instead of looking up their Unicode, instead of the really short and ann...
Bruxelles' price tag for the Britons to leave EU is EUR 60 milliards (British counting).
Not really "we will save much more than the NHS costs us" as one of the proponents of the Brexit stated.
And then, old troubles will surface again ... like fishing.
The Britons will look to fish within their 12 miles,
at the English Channel, they likely have the French with their 12 mile zone approaching or even intersecting...
And then, like a cascade reaction, what about the Dutch, used to fish there, too?
O là là ...
It is easier to disagree on something, than to agree on something new replacing the old existing.
Perhaps contributing to the observation Mr Trump's replacement of Obama care did not work in the way he anticipated. Despite, they had more than five years time to prepare the bill.
And now (on paper) have the majority in President, gouvernment, both Houses.
I'm not sure if this were simply "unpredictable", "challenging" or something else, in regard to work together with and for all of the people, and on an international level.
@hBy2Py I read about the MALDI system, it's very interesting; maybe when you're next around we can discuss it? Also, my GitHub username is "physicsnerd"; I'd like to help clean up homework questions.
It is not possible for one person to overturn the hw policy from scratch. It is also exceedingly difficult for the community to overturn it from scratch. I think small steps like these are the way to go.
The name is also something we have been arguing over for a while; many of us don't like it.
Why does a eutectic point exist for a system of alloy ? Why is it that there is such a definite ratio of composition at which this occurs ?
