Osmosis and solids?

Is it possible that osmosis occur between solids?

For example, if I put a wet fruit on a tissue paper for say a couple of minutes would the water diffuse into the tissue paper?

If possible, please attach a website.

Many thanks to those who answer!

    the example you list is not solid osmosis, it is the liquid in the fruit that is diffusing, not the solids.

    Solids do not diffuse very much if any. But, for example, if you take two very flat metal blocks and place them against each other for a period of time, they will have stuck together due to exchange of electrons. This could be considered diffusion (or not).

    By definition, osmosis refers specifically to diffusion of WATER from a region of relative high thermodynamic activity to a region of relative lower activity.  Typically, those two regions will be divided by a membrane, i.e. a semi-permeable barrier, through which water can pass freely.  If you do a google search on "osmosis," that's the defintion you'll see on all the bazillions of hits you get, so just pick one.

    So since osmosis is about water diffusion, then it is not relevent to solids.  Your wet fruit on a dry paper towel analogy is about something else altogether, it's not about osmosis.
