Abstract: Protein-based materials represent sustainable and easily customizable alternatives to conventional synthetic polymers. With their biocompatibility, bioactivity and genetic tunability, proteins can be customized for a range of biomedical applications. Specifically, protein materials that self-assemble into macromolecular structures and can be produced at large scale are of interest Get price

Minerals are chemical substances composed of atoms arranged in unique crystal structures. A crystal structure describes a highly ordered repeatable arrangement of atoms.Note that there is an important difference between the chemical formula of a mineral and the molecular crystal structure of a mineral! A chemical formula is only a description of the elements that make up a pure chemical compound. Get price

6 Metamorphic Rocks – An Introduction to Geology

6.4 Metamorphic Environments. As with igneous processes, metamorphic rocks form at different zones of pressure (depth) and temperature as shown on the pressure-temperature (P-T) diagram. The term facies is an objective description of a rock. In metamorphic rocks facies are groups of minerals called mineral assemblages. The names of metamorphic facies on the pressure-temperature diagram reflect Get price
