Strange things happen when a crystal is split in two

The remarkable strength of ionic crystals is easily explained at the atomic scale: Positively and negatively charged atoms sit side by side in a repeating periodic arrangement. The strong electrostatic force in between keeps ...

How to separate linear and ring-shaped molecules

What is the difference between linear chains and rings composed of the same material? The molecular building blocks are identical, but from a mathematical point of view, the two structures have distinct topologies, ring and ...

Revealing polymeric fluids behavior at the microscopic scale

An important concept in future healthcare is the development of devices called "lab on a chip." These "chips," not related to the electronic ones found in computers, are small devices in which biological fluids – blood ...
