The results of this work demonstrate the use of DoE to assess the differences and parameter dependencies of different materials in the GDL of PEMFC.
This is the principle that Newton tested by constructing pendulums with wooden boxes as their bobs, which he would fill with different materials in order to see whether those differences made a difference to the speed of falling; they didn't.
We soaked different materials in coffee for months to test them.
Artificial flowers were extremely popular and were made in many different materials in both home and factory.
Machines separate out different materials, in much the same way as Mrs Hiyale and her fellow rag-pickers do back in Mumbai.

Of the 20 different materials in a phone, only a small fraction are ever recuperated, even in the most sophisticated electronics recycling plants such as the huge smelting and electrolysis facility run by metals firm Umicore in Antwerp.
Microscope objectives may contain as many as eight or nine elements, some of which may be made of different materials in order to bring all colours of light to a common focus, and thus prevent chromatic aberration.
Among those groups was one that discussed the latest advances in solid-state physics, an emerging field that analyzed the conductivity and other properties of different materials in relation to their atomic structures.
Effect of different materials in the mass.
It compares four different materials in four differential accelerometers.
