Abstrakt: Motivated by proposed entangled molecular structures known as ravels, we introduce a method for constructing such entanglements from 2-string tangles. We then show that for most (but not all) arborescent tangles this construction yields either a planar θ4 graph or contains a knot. [ABSTRACT FROM AUTHOR]
