The OCAFs have two functional elements – the large body of the materials is air-filled open cells with typical cell size greater than 1 μm and the walls between the open cells consisting of mesoporous aerogel formed by the polyurea strands of typical diameter 50 nm.
Everyone had laptops open, cells in hand.
The filler did not open cells or induce structural defects.
The effect of partially open cells is also considered.
These polymeric materials possessed open-cell structures.
Many open-cell foams exhibit ellipsoidal rather than spherical cells.
In particular, they had unusual bimodal cell size distributions, and some open or partially open-cell structures.
Open-cell and closed-cell structures are found to exhibit similar wave propagation behavior.
The two carbon substrates were C1, an open structured carbon aerogel derived from a resorcinol formaldehyde polymer aerogel, and C2, a commercial nanoporous carbon from MAST Carbon (UK).
The guards' keys were used to open the cells.
