#aerocel
- Aerocell — A porous, insulating, and ultra-light material characterized by a cellular structure in which the liquid phase of a gel has been completely replaced with a gas (usually air) without the solid network collapsing. It is widely used in industrial thermal insulation, the aerospace industry, and construction due to its extremely low thermal conductivity.
- Aerocele — A gaseous tumor formation, pneumatic hernia, or pathological accumulation of air structurally located within a natural cavity or adjacent soft tissue, frequently occurring following mechanical trauma, parietal ruptures, or infections with gas-producing anaerobic germs. In surgery, the term describes an abnormal air pouch requiring evacuative puncture or structural decompression.
