Questions & Answers

Q: How can nanoscale technologies be combined with the human scale built environment?

The combination of nanoscale programmable materials and the built environment can be achieved through self-assembly, where materials build themselves through local interactions. This can lead to more efficient construction and manufacturing techniques.

Q: What is the significance of self-folding proteins?

Self-folding proteins provide a tangible model to study the intricacies of protein folding and can be used as an intuitive physical model to understand how self-assembly works at the human scale.

Q: How does 4D printing work?

4D printing involves using multimaterial 3D printing to deposit multiple materials and add a new capability of transformation. This allows printed parts to transform from one shape to another without the need for wires or motors.

Q: How can self-assembly be applied to the built environment?

Self-assembly can be applied to the built environment, particularly in extreme environments where traditional construction techniques are limited. It can also be used in infrastructure, such as developing programmable and adaptive pipes that can change capacity or flow rate without the need for expensive pumps or valves.
