Effects of ammonium polyphosphate/melamine additions on mechanical, thermal and burning properties of rigid polyurethane foams

, 2019
Rigid polyurethane foams are widely used as thermal insulation materials. However, the foams have fairly poor fire performance. Therefore, different flame retardants are used to enhance the fire resistance of the foams.

Carboxylates and the uptake of ammonium by excised maize roots [PDF]

, 1975
The effect of carboxylates (organic acid anions) on NH 4 uptake was studied by changing the carboxylate level of roots prior to uptake experi ments. Succinate was the most effective stimulator of ammonium uptake.
