thread_title:  Question 

message: Hello all, my name is Parthi. I'm new to editing wiki, so I'm not familiar with the procedures or terminology. I am, however, a member of the thermoelectric research community (3rd-year graduate student in Electrical Engineering under Prof. Rajeev Ram).
It seems to me that a bunch of pages (i.e. "thermoelectricity" and "thermogenerator") should be replaced by disambiguation pages. For example, in the case of the "thermoelectricity" page, the "see also" list seems like decent place to start, although there are several items on that list that plainly don't belong. In the case of the "thermoelectric effect" page, things seem to be in better shape. Nevertheless, the scope of the page should probably be defined with thought toward the set of all pages people might click on to learn about the phenomena of thermoelectricity and related applications.
I'm not sure who the admin for each of these pages is, but it seems like a worthy cause to link everything in this area together into two logically distinct pages:
====[page #1] "Thermoelectric Effect": ====
A page describing generally the science of thermoelectricity. It should begin with the three traditional thermoelectric effects (Seebeck, Peltier, and Thomson). There should also be a brief mention of the figure-of-merit with links to the literature, since considerations of this quantity have an important influence on the community of scientists focusing on developing the new generation of thermoelectric materials.
I also believe a brief mention of other solid-state thermally-driven voltage-generating schemes belongs here, despite the fact that the research community refers to phenomena such as solid-state thermionics and nernst-effect devices distinctly from thermoelectricity. I believe this because the word thermoelectricity is often colloquially used as a catch-all term for solid-state thermal-to-electrical devices.
Finally, there should be a discussion of the thermodynamic properties of both generators and refridgerators based on these devices. Questions of reversibility should be addressed here. This section should also contain links to the generator and cooler pages.
The existing page satisfies most of these concerns and seems to have a legitimate scientific dialogue ongoing.
====[page #2] "Thermoelectric Generator": ====
A page describing the development of high-power, efficient generators based on the effects described above. There is a body of information which I cannot find anywhere on wikipedia regarding such topics as the role of heat exchangers and segmentation/cascading in real generators.
This page should contain links to specific applications, such as RTGs (wiki:"Radioisotope thermoelectric generator"), waste-heat-recovery schemes in cars (wiki:"Automotive Thermoelectric Generators"), and more generally energy harvesting (wiki:"Energy harvesting"). There should also be a link to the cooler-device page (wiki:"Thermoelectric cooling") here.
I believe a new page should be created for this purpose, as no existing page seems to address this concern or contain nearly sufficient content to that end.
====Upshot: ====
I would like to communicate with the admins of these pages to address these concerns. I would also like to take over the admin of any pages in this area that people are willing to part with. Does anyone know how this can be accomplished?
There are also a number of people more qualified than myself for this task (obviously, since I'm a graduate student), so if this is the case with the current admin, please let me know. I do not have much experience with wikipedia's admin/editing procedures, so I hope I'm not offending anyone.

thread_title: Upshot: 

message: Hello! First, you should know that particular articles don't have administrators. You just go ahead and make your edits. If you're uncertain of your edits, you can write what you plan to do on the talk page, and wait a few days to see if anyone has useful feedback to offer. There is such a thing as an administrator, but they serve a very different role (things like blocking vandals from editing). You might benefit from browsing WP:Welcome, or just try your best and learn as you go. Anyway, no one's in charge, and lots of articles (and subjects) are in the state they're in not because someone thought carefully through it and decided that that was best, but just because that's the way it was left and no one wants to clean them up. :-)
I don't think you should assume you're less qualified than other editors. On the contrary, being a grad student at a respected university specializing in this area, you would probably be among the most qualified active editors, if indeed you decide to become an active editor.
It's not unusual, at least in physics, for there to be a mess of articles on different aspects of the same subject, without a clear idea of which subjects are in the scope of which articles. It's a difficult but worthy goal to try to organize them. I won't offer specific feedback on your plan since I'm not familiar with most of the relevant pages and don't immediately feel like reading them. Maybe someone else will offer feedback though. There's also the page Wikipedia talk:WikiProject Physics where you can solicit advice from the general Wikipedia-physics-community, when the article talk pages aren't sufficient. Happy editing, --Steve (talk) 01:07, 28 July 2008 (UTC)
thread_title: Responses

message: At the end of the article, there is a brief list of materials with good Seebeck coefficient. I'm interested in bismuth telluride, but when I go to its article, it doesn't say how much that coefficient is (well, it does, but for a very high temperature, if I remember well. Can anyone knowing the subject add an estimate of the thermopower for Bi2Te3 at everyday temperature (20-35 °C), please? --200.59.188.242 (talk) 20:17, 2 August 2010 (UTC)

thread_title: Led to nowhere

message: 'Mateirals with high Seebeck Coefficient(Thermopower)' is a very misleading section.  Many horrible thermoelectric materials have high seebeck coefficients.  ANY insulator has a huge Seebeck coefficient.  Should this section be switched to 'Materials with high Power Factors' seeing as this is really what is looked for in application?  The SrRuO3 example is a good example of how this is misleading.  SrRuO3 is an average to poor thermoelectric oxide...and the quoted thermopower isn't exactly high - but it is reasonable for SrRuO3's conductivity.
I Think the section needs to be rewritten after a better explination of thermopower is discussed....  —Preceding unsigned comment added by 75.102.96.4 (talk) 17:48, 14 April 2011 (UTC)
thread_title:  Materials with high seebeck coefficient...hmmm... 

message: It seems like thermopower contains a lot of parallel material from thermoelectric effect. Shall we merge them together? --147.83.123.130 (talk) 18:29, 3 April 2013 (UTC)
thread_title:  Can we merge this with Thermoelectric effect? 

message: See . This has now been added twice and reverted (by me) twice. My complaint is that there are probably tens of thousands of papers on the topic of "materials with a high Seebeck coefficient". I don't think we are helping readers by citing one obscure random paper in that category—a paper which is not especially central or topical or accessible. If we want a citation here, it should at least be a review article. I'll add this one. I wonder whether the person adding this one obscure random paper is its author, engaging in self-promotion? Well, whether or not that's the case, it doesn't matter, I still think the reference should be deleted. Others are welcome to agree or disagree. --Steve (talk) 14:27, 16 January 2018 (UTC)
