That experience led to research in thermal compounds, and their material composition.

The material composition of the astronomical objects can often be examined using:

Doing the latter in a semiconductor would require a change of the material composition.

Sharpening stones come in a wide range of shapes, sizes and material compositions.

Today, researchers use neutrons generated by the reactor to study material composition.

All this is ancient material, none of it original compositions by Taita.

Thus the material composition needs to be factored into the albedo analysis to determine age.

Finding out the material composition of the object is also necessary before deciding which strategy is appropriate.

A new class of reactive material compositions is now under investigation by military.

The contrast seen in the image is based either on the object's geometry or material composition.
