Chemistry and Materials Science
Materials science is an applied science concerned with the relationship
between the structure and properties of materials.
Chemistry provides information about the structure and composition of
materials as well as the processes to apply and synthesize them.
Chemists play a predominant role in materials science.

Chemists have created hybrid molecules by bonding fragments of
very different materials.
Molecular Hybrid Materials: properties are different from those of
the
corresponding
individual
fragments;
adopt
very
complex
organizations; specially relevant those obtained by linking synthetic
and natural fragments.
