Questions and Answers

What is the main advantage of the bottom-up method in nanomaterial synthesis?

  • Increasing the speed of nanomaterial production
  • Reducing the cost of nanomaterial synthesis
  • Controlling the size, shape, and structure of nanomaterials (correct)
  • Enhancing the electrical properties of nanomaterials

What is the difference between an aggregate and an agglomerate?

  • Agglomerates are formed at higher temperatures than aggregates
  • Aggregates are held together by weak interactions, while agglomerates are rigidly joined together
