ABSTRACT:
A method processes a gel monolith comprising pores filled with liquid, an inner region, and an outer region. The method includes removing a portion of the liquid from the pores of the gel monolith while both the inner and outer regions of the gel monolith remain wet. The method further includes shrinking the volume of the gel monolith during the removal of a portion of the liquid, with the gel monolith becoming correspondingly more dense. The method further includes subsequently removing substantially all of the remaining liquid from the pores of the gel monolith. Subsequently removing substantially all of the remaining liquid includes modulating a temperature gradient between the outer region and the inner region.
