Task
You are to research the development of emerging new materials used in the following scientific areas
- Biomedical
- Industrial
To do this, you will research and answer the following questions on various different materials
You can work in pairs, no more than 3 per group.
Answer the questions in your books or type up in word document.
You would need to print your document and stick it into your books
