Physiological roles of lignins - tuning cell wall hygroscopy and biomechanics. [PDF]

open access: yesNew Phytol
Summary Lignins constitute the second most abundant carbon‐storing biopolymers in the biosphere. These phenolic polymers accumulate in different concentrations, compositions, and localisations within and between cell wall layers and cell types. Lignins were acquired during plant terrestrialisation 450 million years ago, and the diversification of their

Foliar spectral signatures reveal adaptive divergence in live oaks (Quercus section Virentes) across species and environmental niches. [PDF]

open access: yesNew Phytol
Summary Genomic tools have advanced our understanding of species and population structure, but distinguishing neutral from adaptive evolution remains challenging due to limited methods for measuring a broad spectrum of phenotypic traits. We used spectroscopic data from preserved leaves to test for adaptive divergence among populations of live oaks ...

Biochemical composition of cover crop residues determines water retention and rewetting characteristics

open access: yesAgronomy Journal, Volume 115, Issue 6, Page 3173-3187, November/December 2023., 2023
Abstract When cover crop residues are left on the soil surface, their decomposition is mainly influenced by environmental conditions in residue layers, particularly residue water potential (ψresidue). Thus, models for surface residue decomposition in conservation tillage systems should include a sub‐module that can simulate hourly changes in ψresidue ...

In Situ Lignin Sulfonation for Highly Conductive Wood/Polypyrrole Porous Composites

open access: yesAdvanced 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

open access: yesFire 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 ...
