Diversity of knot solitons in liquid crystals manifested by linking of preimages in torons and hopfions [PDF]

open access: yes, 2017
Topological solitons are knots in continuous physical fields classified by non-zero Hopf index values. Despite arising in theories that span many branches of physics, from elementary particles to condensed matter and cosmology, they remain experimentally

Nodal-knot semimetals [PDF]

open access: yes, 2017
Topological nodal-line semimetals are characterized by one-dimensional lines of band crossing in the Brillouin zone. In contrast to nodal points, nodal lines can be in topologically nontrivial configurations. In this Rapid Communication, we introduce the

Topological semimetals carrying arbitrary Hopf numbers: Fermi surface topologies of a Hopf link, Solomon's knot, trefoil knot, and other linked nodal varieties [PDF]

open access: yes, 2017
We propose a type of Hopf semimetal indexed by a pair of numbers $(p,q)$, where the Hopf number is given by $pq$. The Fermi surface is given by a preimage of the Hopf map, which consists of loops nontrivially linked for a nonzero Hopf number.

Application of Chitin/Chitosan and Their Derivatives in the Papermaking Industry

open access: yesPolymers, 2018
Chitin/chitosan and their derivatives have become of great interest as functional materials in many fields within the papermaking industry. They have been employed in papermaking wet-end, paper surface coating, papermaking wastewater treatment, and other
