An inert gas is used, so that the material does not chemically react.

By using the device, it is easier to see how many different materials react with fire.

These materials do not react with the resin but are an integral part of the advanced composite system.

This solid material then does not react with the contaminants.

The way a material reacts under stress is a question of critical relevance to it's strength and versatility for various uses.

Among the experiments is a set of investigations of how various materials react to the space environment over a long time.

These materials, being basic, can react readily with the metal, producing hydrogen and heat, a dangerous combination.

The new concerns are fueled by a better understanding of how implanted materials react with the immune system.

Different materials react to temperature in different ways.

When exposed to the oxygen in air, the materials react to produce heat.
