+    By default, `sco2es.PackedBed` uses [CoolProp](https://github.com/coolprop/coolprop) to calculate the properties of
+    CO~2~ and assumes that the solid particles are made of [`Alumina`][sco2es.properties.Alumina], for which empirical correlations are used to calculate
+    relevant properties. To use a material other than alumina, create a class matching the protocol
+    [`SolidProperties`][sco2es.properties.SolidProperties] and set the [`solid`][sco2es.PackedBed.solid] attribute.
