Viscoelastic properties of wood across the grain measured under water-saturated conditions up to 135\degree C: evidence of thermal degradation [PDF]
Journal of Materials Science 43 (2008) 3210-3217, 2009 In this paper, the viscoelastic properties of wood under water-saturated conditions are investigated from 10\degree C to 135\degree C using the WAVET* apparatus. Experiments were performed via harmonic tests at two frequencies (0.1 Hz and 1 Hz) for several hours.

Fully Bio‐Based Epoxy Resins from Liquefied Wood for Chemically Recyclable Wood Coatings
Advanced Functional Materials, EarlyView.A bio‐based and chemically recyclable epoxy resin derived from liquefied wood and its use in wood coatings is presented. The resin exhibits mechanical, thermal, and water‐resistant properties comparable to commercial coatings and can be chemically recycled and reused. This approach provides fast access to glossy and fully biobased durable wood coatings

Computational study of the effects of density, fuel content, and moisture content on smoldering propagation of cellulose and hemicellulose mixtures [PDF]
Proc. Combust. Inst. 37 (2019) 4091-4098, 2018 Smoldering combustion plays an important role in forest and wildland fires. Fires from smoldering combustion can last for long periods of time, emit more pollutants, and be difficult to extinguish. This makes the study of smoldering in woody fuels and forest duff important.
