Marshmallow-like gels usually have strong hydrophobicity and oleophiliicity. They can be used oil/water separation media like sponges, removing organic compounds from water by absorbing them and then releasing them upon being squeezed out.

Surface-treated VTMS-VMDMS gels have superhydrophobicity and superoleophobicity on any cut surface. Novel applications to new antifouling and self-cleaning surfaces would be developed by carefully tuning the surface energy and roughness of the monolith.
Thermal insulating / LN2 retention
Marshmallow-like gels exhibit a low thermal conductivity of about 30 mW m−1K−1. It can be used as a simple container for cryopreserved embryos by filling into a thermos bottle and absorbing LN2.
