2. 1. Fungal degradation patterns and toxicity of furfurylated wood

   Author : Annica Pilgård; RISE; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Daphtox; Quantitative real-time PCR; Furfurylation; Microtox; Basidiomycota; Acetylation; Wood modification.; Daphnia magna; Thermal modification; Trametes versicolor; Decay; Vibrio fischeri;

   Abstract : The demand for timber products is increasing with global population and affluence. Concerns regarding conventionally used toxic wood preservatives and the deforestation of tropical forests have become more prominent both socially and politically. Wood based products are generally recognised as an environmentally favourable raw material. READ MORE

4. 2. Wettability of modified wood

   Author : Maziar Sedighi Moghaddam; Agne Swerin; M. Per Calessson; E.P. Magnus Wålinder; Callum Hill; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Wood; dimensional stability; dynamic wettability; surface chemistry; microstructure; swelling; multicycle Wilhelmy plate method; contact angle; sorption; acetylation; furfurylation; surface modification; Kemi; Chemistry;

   Abstract : Despite many excellent properties of wood which make it suitable for many applications, it suffers from a number of disadvantages limiting its use. For instance, modification is needed to reduce water sorption and to improve decay resistance, dimensional stability and weathering performance. READ MORE

5. 3. Wood Plastic Composites made from Modified Wood : Aspects on Moisture Sorption, Micromorphology and Durability

   Author : Kristoffer Segerholm; Ove Söderström; Magnus Wålinder; Mats Westin; Pia Larsson Brelid; Per Johan Gustafsson; KTH; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Wood plastic composites; WPC; acetylation; heat treatment; furfurylation; moisture sorption; micromorphology; decay; UV laser; soil test; Biomaterials; Biomaterial;

   Abstract : Wood plastic composite (WPC) materials have seen a continuous market growth worldwide in the last decade. So-called extruded WPC profiles are today mainly used in outdoor applications, e.g. decking, railing and fencing. READ MORE

6. 4. Characteristics of wood plastic composites based on modified wood : Moisture properties, biological performance and micromorphology

   Author : Kristoffer Segerholm; Magnus Wålinder; Mark Hughes; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood plastic composites; WPC; acetylation; thermal modification; furfurylation; moisture sorption; biological durability; UV excimer laser; micromorphology;

   Abstract : Biobased materials made from renewable resources, such as wood, play an important role in the sustainable development of society. One main challenge of biobased building materials is their inherent moisture sensitivity, a major cause for fungal decay, mold growth and dimensional instability, resulting in decreased service life as well as costly maintenance.

7. 5. Moisture-related properties of modified timber - an experimental study

   Author : Hannah Epmeier; Chalmers tekniska högskola; []
   Keywords : Scots pine; material properties; chemical modification; building components; timber; bending creep;

   Abstract : Wood has long traditions as a structural and building material. In those cases in which its natural features are not sufficient, chemical modification can eliminate some shortcomings. READ MORE
