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 ...

Scientists at MIT say they have discovered the factors that determine whether a DNA knot moves along the strand or “jams” in place. The findings could help researchers develop ways to untie ...

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 is an important field of study as the ...

Molecular knots are common in nature. Polymer chains can often form them, and even circular DNA and about 1 percent of known proteins show knotted structures. There are more than 6 billion known ...

The breakthrough knot has eight crossings in a 192-atom closed ... and elasticity of materials which will enable them to weave polymer strands to generate new types of materials.

Being able to make different types of molecular knots means that scientists should be able to probe how knotting affects strength and elasticity of materials which will enable them to weave polymer ...

The advantage of using different types of molecular knots is that scientists can probe the effects of knotting from the standpoint of strength and explore weaving unique polymer strands for ...

Drawing inspiration from knots, an interesting idea presents itself - polymer optical fiber knots. The knot's three-dimensional structure breaks the fiber's original circular symmetry ...

Being able to make different types of molecular knots means that scientists should be able to probe how knotting affects strength and elasticity of materials which will enable them to weave polymer ...

Scientists have tied molecules into the tightest knot ever achieved — a breakthrough ... of materials which will enable them to weave polymer strands to generate new types of materials.

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 is an important field of study as the presence ...
