A second one of the materials is at least a partially crystalline structure and has a second temperature which is lower than the first temperature at which the second material activates. A porous membrane is supported by the substrate. An attachment is between the substrate and the membrane. The attachment results from the second material of the substrate activated at a temperature less than the first temperature to engage portions of the membrane at spaced apart locations and fix together the membrane and the substrate upon the second material cooled to a temperature less than the second temperature.
