DOI: 10.1002/adfm.201703258
Abstract: Vitrimers are dynamic polymer networks with unique viscoelastic behavior combining the best attributes of thermosets and thermoplastics. Ionic vitrimers are a recent class of dynamic materials, where 1,2,3-triazolium cross-links are reshuffled by trans-N-alkylation exchange reactions.… read more here.

DOI: 10.1016/j.commatsci.2019.109410
Abstract: Abstract An “effective bond model” of covalent cross-links between carbon nanotubes (CNTs) is developed for mesoscopic simulations of CNT materials. The cross-links are represented by discrete stretchable bonds between mesoscopic nanotube elements. These bonds induce… read more here.

DOI: 10.1016/j.foodchem.2018.02.090
Abstract: Type I photo-oxidation generates Trp-(TrpN) and Tyr-derived (TyrO) radicals in proteins which can dimerize producing cross-links, or alternatively react with O2. It was therefore hypothesized that the O2 concentration may have a significant effect on… read more here.
