It's important to remember that a patent is the how-to part -- "the present invention teaches ..." -- not the what-we're-doing part, which could be "investigating how such-and-such might be done" which might even include "so far we've tried 27 things and failed."
What a disclosure cannot include, and not run afoul of the various grace periods, is a descripton what worked and how you actually did the what-worked.
If you look at a collection of disclosures I did for a while they related to simulating rotating masses using software to make the electric grid more stable with non-rotating sources of generation as well as loads which did not demonstrate some form of angular momentum. If I opined ("wrote a paper about") "the problem with modern generating sources is that many of them lack angular momentum" that's just words and the problem to be solved -- the "the present invention teaches ... how to implement angular momentum in a non-rotating generator" part -- isn't disclosed.
All that said, consult competent legal advice. As inventors we're too predisposed to think in our own favor for you to answer this question for yourself.
Finally, when working on something which may be patentable it really is best to not say anything. It doesn't feel as good as talking about your work, but unless you're very good about not disclosing anything that may hurt you in the future, it feels a lot better in the long run.
