The secret life of knots

Nanotechnologies require a detailed knowledge of the molecular state. For instance, it is useful to know when and how a generic polymer, a long chain of polymers (chain of beads), knots. The study of molecular entanglement ...

Coming round to stable self-assembly

Nanostructures that assemble themselves from polymer molecules could prove to be useful tools in chemistry and industry. However, it is difficult to develop structurally robust self-assembling materials because they are often ...

Physicists discover a new kind of friction in the nanoworld

Whether in vehicle transmissions, hip replacements, or tiny sensors for triggering airbags: The respective components must slide against each other with minimum friction to prevent loss of energy and material wear. Investigating ...

Invisible pattern can put a stop to counterfeit designer clothing

There is now a way to differentiate between designer clothing and knockoffs. Chalmers researcher Christian Müller has produced a thread with unique optical properties, which can be used to create invisible patterns in fabrics ...
