In Situ Lignin Sulfonation for Highly Conductive Wood/Polypyrrole Porous Composites
Advanced Materials Interfaces, Volume 10, Issue 1, January 5, 2023., 2023 A facile approach for the fabrication of porous lightweight and mechanical robust wood/polypyrrole composites with high conductivity is demonstrated. The in situ lignin sulfonation approach for native wood structure as a multifunctional platform is advantageous for controlled and improved conductive polymer integration toward sustainable and low‐cost ...

A model for the pyrolysis of two Nordic structural timbers
Fire and Materials, Volume 46, Issue 1, Page 55-68, January/February 2022., 2022 SUMMARY Performance‐based design of the timber structures' fire resistance is often based on the reduced cross section and thus relying on empirical and numerical assessment of the charring propagation. The current work aims to construct models for the pyrolysis of spruce and pinewoods to allow coupled simulations of the cross‐section reduction and ...
