## Abstract BACKGROUND: Supercritical drying (SCD) of aerogels entails replacement of the primary solvent ethanol in the porous solid network with supercritical carbon dioxide (SCCO~2~) without a vapor–liquid interface to avoid collapse of the pores by capillary forces. The present paper proposes a
