Weaire–Phelan structure
Have you ever built a tower using blocks or Legos? Well, scientists and engineers like to build things too, but they use much smaller building blocks called atoms.
The Weaire-Phelan structure is a special way of arranging atoms in a material. Imagine you have a big jar full of little water balloons (we'll call them atoms). You want to pour them out and arrange them in a way that they all fit together really nicely, without leaving any spaces or gaps between them.
One way to arrange them would be to create a simple pattern, like a checkerboard. But the Weaire-Phelan structure is more complex than that. Instead, imagine taking two soap bubbles and connecting them together at their edges. The shape that's created is called a "dodecahedron" - it looks like a 12-sided dice.
The Weaire-Phelan structure is made up of lots of these dodecahedrons, all connected together in a way that creates an overall shape that resembles a foam or a sponge. This special arrangement is very efficient because it uses the smallest amount of space possible, while still allowing atoms to move around and interact with each other.
Scientists have been studying the Weaire-Phelan structure for decades, and they've discovered that it can be found in all sorts of things - from metals and plastics to certain types of foam (like the ones you might find in a cushion or a mattress). It's a very cool way of arranging atoms, and it helps scientists and engineers make better materials that can do all sorts of useful things.
