Knot theory provides a rigorous mathematical framework to classify and study the entanglements that occur in polymer systems. By applying topological methods, researchers can decipher how knots and ...

With a newly discovered mathematical tool, researchers are hoping to gain unprecedented insight into the structure of complex ...

(Nanowerk News) Plastics or DNA: Many molecules are so long that they can form knots, much like tying shoes. Whereas it is still disputed whether right- and left-handed people prefer to tie their ...

Knots are everywhere—from tangled headphones to DNA strands packed inside viruses—but how an isolated filament can knot itself without collisions or external agitation has remained a longstanding ...

Robots may soon mimic the human sense of touch, with advances in flexible tactile detection aiming to endow them with the ability to sense friction and slip. Polymer optical fiber knots are at the ...
