Estimation of wood density and chemical composition by means of diffuse reflectance mid-infrared Fourier transform (DRIFT-MIR) spectroscopy.
TL;DR: Calibrations for density, lignin, and cellulose were established for all wood species combined into one data set as well as for the separate Sitka spruce data set and relationships between wood resin and MIR data were constructed.

Characterization of 25 tropical hardwoods with Fourier transform infrared, ultraviolet resonance Raman, and 13C‐NMR cross‐polarization/magic‐angle spinning spectroscopy
Mari Nuopponen,Hanne Wikberg,Gillian M. Birch,Anna-Stiina Jääskeläinen,Sirkka Liisa Maunu,Tapani Vuorinen,Derek Stewart +6 more
TL;DR: In this paper, Fourier transform infrared (FTIR), ultraviolet resonance Raman (UVRR), and 13 C-NMR cross-polarization/magic-angle spinning spectroscopy were used for principal component analysis.

Characterisation of the initial degradation stage of Scots pine (Pinus sylvestris L.) sapwood after attack by brown-rot fungus Coniophora puteana
Ilze Irbe,Ingeborga Andersone,Bruno Andersons,Guna Noldt,Tatiana Dizhbite,Nina Kurnosova,Mari Nuopponen,Derek Stewart +7 more
TL;DR: The results showed that irreversible changes in wood structure started immediately after wood colonisation by fungal hyphae and the results generated here will assist in the understanding of the biochemical mechanisms of wood biodegradation by brown-rot fungi with the ultimate aim of developing novel wood protection methods.

Hemicelluloses and pectins in 25 tropical hardwoods
TL;DR: The noncellulosic carbohydrate compositions of 25 tropical hardwoods from Ghana were determined by acid methanolysis and gas chromatography-mass spectrometry (GC-MS) as discussed by the authors.

A method for the non-destructive analysis of wood
Derek Stewart,Mari Nuopponen +1 more
- 12 May 2006
TL;DR: In this paper, a non-destructive analysis of wood, for example sawn untreated wood or live standing trees, is provided, which exposes the wood surface to infrared radiation to generate a primary spectrum which is collated and compared with the calibration model.
