Structure instrument

This chapter set out approaches for binding electron structures of organic ion-radicals with their reactivity. Of course, an amount of structural data is much greater than the data on reactivity. It is commonplace in this field that structural (instrumental) data are accumulated more rapidly than data on reactivity from chemical experiments.

Many composites, such as PMCs reinforced with carbon and aramid fibers, and silicon carbide particle-reinforced aluminum, have low CTEs, which are advantageous in applications requiring dimensional stability. Examples include spacecraft structures, instrument structures, and optical benches. By appropriate selection of reinforcements and matrix materials, it is possible to produce composites with near-zero CTEs.
