This edition: Modern Materials and the Solid State: Crystals, Polymers and Alloys
In this unit, the focus shifts from fluids and their solutions to solids, whose atoms and molecules are fixed in definite arrangements. Examples of molecular configurations range from crystals in a mineral collection, to metal alloys, to long polymer chains. One promising area of polymer research may allow the delivery of essential drugs such as insulin to be taken orally and delivered directly into the bloodstream. Bioplastic-enclosed nanoparticles encasing the drug have the ability to withstand the body’s corrosive digestive system. Extremely high-temperature resistant alloys are another important application of the chemistry of the solid state.
