I am also interested in finding out about how to prepare Sol Gel samples for TEM. Has anyone ever done this work? How thin do the samples need to be? Any suggestions?

Hi, I can think of two different ways to do that.
i) Impregnate your sample with an epoxy resin, and cut it with a microtome into slices about 60 nm thick;
ii) Crush your sample into a powder, disperse it in ethanol, let it rest for a few minutes and put a drop of the supernatant on the microscopy grid.

If you want, have a look at
Journal of Microscopy, 226 (2007) 156-162.
where both techniques are used.
