Systems and methods for making a monolithic gel body. Some systems can include a substrate, a sol, an ammonia atmosphere. Some methods can include applying a first quantity of the sol to the substrate to form a first coated substrate, and positioning the first coated substrate in the ammonia atmosphere to cure the first quantity of sol to form a first supported gel comprising a first gel supported by the substrate. Such methods can further include applying a second quantity of the sol to the first supported gel to form a second coated substrate comprising the second quantity of sol and the first supported gel. Some methods can include positioning the substrate in the ammonia atmosphere while applying the sol onto the substrate to form a monolithic gel body by a layering process. |
