Oxidative phosphorylation?[edit]

What is the name of this mitochondrions' internal membrane process, where ADP and ATP can diffuse only at the same time in opposite directions. It's energetically free. Unfortunatelly I only know its Polish name. --Taw

Tell us the name in Polish, maybe someone will know. Na przykła€ ja :) Karol 20:36, Jun 22, 2005 (UTC)
Oxidative phosphorylation? Using the Electron transport chain and ATP synthase? That's all I can think of. delldot | talk 15:54, 18 January 2006 (UTC)[reply]

Use in math[edit]

Can a mathematician discuss the use of the term in mathematics?

If it has a definite mathematical meaning, then it should be included in WikiPedia, I think. Karol 20:36, Jun 22, 2005 (UTC)

Membranes in Fuel Cells[edit]

Perhaps a section on the MEA (Membrane Electrode Assembly) in fuel cells should be created. It seems that it would be an appropriate link between artificial membranes and one more region of the physical sciences.

Disambiguate[edit]

This should turn into a diambiguation page that leads to different articles for the different uses in biology, mathematics, and theoretical physics (as it relates to M-theory). – Minh Nguyễn (talk, contribs, blog) 22:44, 9 July 2005 (UTC)[reply]

Definition[edit]

Can anyone tell me why the following paragraph was deleted?

A membrane is a thin, typically planar structure or material that separates two environments. Because it sits between environments or phases and has a finite volume, it can be referred to as an interphase rather than an interface. Membranes selectively control mass transport between the phases or environments.

In fact your definition is more accurate than the current one. The complete article needs to be revised and should refer to the various kinds of membranes.

Membranes in Mechanics and Engineering[edit]

There is no reference to membrane setions used in mechanics or engineering. There they are not restricted to the seperation of environments.

Membranes to me basically and primarily are a kind of "physical body" that the evolution found useful for many applications and can be described mathematically, depending on its virtue and purpose. The formulation will certainly be different for segregation of phases or protein diffusion than for mechanical vibrations of a membrane as implemented in engineering devices.

Hence there should either be a disambiguation page or a clear indication to the various possible characteristics or definitions of membranes in different areas. Biology certainly is not the only playing ground of membrane theories. Unfortunately, I am not a native English speaker and therefore do not see myself being able to contribute to this matter. However, I would strongly appreciate any further detail on membrane theory, particularly in mechanics.

Conversion to article[edit]

Just a note for anyone else confused about the recent conversion from disambiguation page to article: it looks like the “per talk” might have referred to Talk:Membrane (selective barrier). Vadmium (talk, contribs) 05:05, 19 January 2012 (UTC).[reply]


Requested move 11 July 2016[edit]

The following is a closed discussion of a requested move. Please do not modify it. Subsequent comments should be made in a new section on the talk page. Editors desiring to contest the closing decision should consider a move review. No further edits should be made to this section.

The result of the move request was: No consensus. — JFG talk 03:27, 22 July 2016 (UTC)[reply]

Membrane → Membrane (selective barrier) – This article describes selective barrier membranes. However, membranes can be a lot more, and imho there is no reason to put their use as selective barriers over a more general description (for example as described under the == Definition == heading on this talk page). Also note that most entries on this talk page actually describe confusion about the type of membrane described in this article (see on this talk page under the ==Use in math==, ==Disambiguate== (which was in principle a non-formal request for this move), == Definition ==, == Membranes in Mechanics and Engineering == headings, all of which would be addressed, if this article was moved to Membrane (selective barrier), and "Membrane" itself linked directly to the disambiguation page. Further, note that this article according to page view statistics (despite being the default "membrane") has 100-300 page views, whereas "Biological Membrane" has 100-200, "Cell Membrane" has 900-1900, "Basement Membrane" has around 200. So there is no real reason to give the membrane as a selective barrier such a predominant role from that perspective. Maybe most importantly, though: A membrane as such does not necessarily let something pass through it (please just google), whereas that is a very important aspect of a selective barrier membrane and appears in the first sentences of this article. Being led here when searching for the general term "membrane" is misleading at best. I would have been bold and moved the article, but unfortunately, the article Membrane (selective barrier) already exists (as a link to "Membrane") and I do not have the rights to delete that article out of the way.

  • Oppose The underlying choice here (neglecting a few terms with significantly less extensive use) is between the physical characteristics of flexibility evident to tactile and visual examination or of less obvious permeability. The original use of the term membrane was to describe biological structures with both attributes but with essential function as selective barriers. Finding this definition first will provide that fundamental concept of the most widely sought subjects, and may provide all required information. The alternative of first finding the disambiguation page would require a choice without that knowledge, and distracting definitions emphasizing flexibility may obscure dual functionality of the subjects of widest interest. Thewellman (talk) 02:07, 12 July 2016 (UTC)[reply]
Hi, thanks for the comment. Are you really sure that for instance Basement membrane is "significantly" less extensively used than selective barrier membrane? Or the membrane of a microphone or loudspeaker, to all of which the current description really does not apply? If I heard that a loudspeaker has a membrane, or that the eardrum is a membrane, or that epithelial cells sit on a membrane, and then looked up "membrane" on wikipedia, I would be very confused. The first sentence under the ==Definition== topic on this talk page provides a much more general description of what a membrane is, with semi-permeabel membranes being a more special (and yes, very important) usage. I aggree that the disambiguation page (or a short, more general description of membranes should be provided under the "membrane" term, in order to guide the reader. Gormfull (talk) 10:12, 12 July 2016 (UTC)[reply]
In the absence of additional response to this suggested change, I suggest you proceed as proposed including a brief introductory definition on the disambiguation page including both the flexibility and permeability attributes of derivative usage. Thewellman (talk) 23:56, 19 July 2016 (UTC)[reply]
