With that in mind, scientists at the National Institute of Standards and Technology (NIST) have used carbon nanotubes to create a coating for that foam, that reduces its flammability by 35 percent.

The software of the BetterPyc 380 automatically calculated the average open-cell content and standard deviation for each foam sample. The results suggest that the foam-grey sample has the highest open ...

The foam acts like a sponge, Jacobsen says, soaking up the gas. Jacobsen and his colleagues have collected foam samples that are 60 percent methane by volume.

The authors used well-characterised liquid foam samples. Thus, they knew all the parameters needed for computing predictions on the acoustics characteristics of existing foam models.
