The solubility of lignin in different IL species were investigated using the monomeric (coniferyl alcohol and Coumaryl alcohol), dimer (lignin β–O–4 and lignin 4–O–5 linkage), trimer (dibenzodioxocin) and polymeric structure of lignin as model components for the COSMO-RS calculations. In...
The standard methods for measuring the molecular weights of thermoplastics were not designed for polymers with extremely long chains. Their limitations are highlighted in this report. They are most apparent in the case of SEC, which depends for its viability on complete solubility of the sample, wh...
Implantable medical devices may be fabricated from any number of suitable biocompatible materials, including polymeric materials. The internal structure of these polymeric materials may be altered utilizing mechanical and/or chemical manipulation of the polymers. These internal structure modifications may be ...
Therefore, atomistic simulations techniques have proven to be a useful tool for the understanding of structure-property relationships of materials and in particular MD can be used for detailed descriptions of the complex morphologies and transport mechanisms associated with rigid glassy structures. 展开 ...
