the chemical category? Also, I noticed that Debye forces were missing from the dispersive category as well, but perhaps adhesion via Debye forces doesn't happen due to the dipole-containing substance's preference towards cohesion rather than adhesion in cases where its met by a non-polar substance? If this is the case, perhaps this should be mentioned in the category of dispersive adhesion?
508:
Hydrogen bonding is a kind of dipole-dipole bonding (Keesom forces) that involves hydrogen, and is therefore a very strong kind of dipole-dipole bonding. Given how Keesom forces are a sub-category of Van der Waals forces, shouldn't hydrogen bonding be mentioned under the dispersive category, and not
397:
this article discusses the specific mechanisms by which surfaces adhere to one another from a materials science perspective. it has a focus on technical mathematical models, and simply adding it to the adhesion page would disproportionately increase the technical details regarding surface adhesion
272:
the first paragraph does not say that adhesion is defined as only being on a molecular level, but more importantly, mechanical adhesion does happen on a molecular level. Stringing is one example. It is somewhat analogous to velcro on a molecular scale.
423:
Yeah this page needs help in general. I think there is a lot of redundancy between the two articles right now that can be eliminated if they are merged. Just because the incoming text is a little more technical doesn't mean it shouldn't be merged.
262:
ONLY refers to "sticking" that occurs at a molecular level? In which case, it would seem that mechanical adhesion, such as velco wouldn't qualify; and if not, what would you call it when things stick to one another but not at a molecular level?
398:
mostly as an application of materials engineering. i agree that its status as an orphan needs work, wouldn't it be better to link up this page with
Adhesion, Sticky Tape, Glue, Biomimetics, van der Waals forces, etc?

14:19, 17 February 2007 (UTC) This page could use some more detail on molecular (biochemical) adhesion, including definition and differences between adhesion and cohesion. -

There are three pictures of water adhering to different things. How does that work? Is it related to the hydrogen-bond cohesion?
