Scalability
Another major challenge is moving from small laboratory samples to mass production. Materials used in a laboratory may behave differently when produced in large quantities.
Environmental Considerations
Not every advanced material is automatically environmentally friendly. Engineers must consider the resources, energy, chemicals, and waste associated with production, use, and disposal.
The Future of Advanced Materials
The discovery of materials that combine several desirable qualities will probably be crucial to engineering’s future.
Future materials could be lighter, stronger, smarter, more durable, energy-efficient, and environmentally responsible at the same time.
