  1. 1. Surface modification of birch and acetylated birch wood by silicone nanofilaments

    Author : Haiyan Yin; Magnus Wålinder; Agne Swerin; Andra Dédinaité; Jan Van den Bulcke; KTH; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acetylated wood; surface modification; superhydrophobicity; plastron; wetting; silicone nanofilaments; UV irradiation; mold resistance; blue stain.; Acetylerat trä; ytmodifiering; superhydrofobicitet; plastron; vätning; silikon-nanofilament; UV-bestrålning; mögelresistens; blånad.; Building Materials; Byggnadsmaterial;

    Abstract : The increasing awareness of sustainability motivates the development of building materials from renewable resources. The requirements of wood-based products with improved durability, for example, enhanced liquid repellence and UV and biological resistance, are still a challenge. READ MORE

  2. 2. Chemical and physical incorporation of bio-molecules into wood materials for energy storage

    Author : Meysam Nazari; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The environmental impact of fossil-based materials in the building industry and significant energy consumption in residential buildings have urged new research areas in using bio-based, renewable and sustainable materials for production of energy smart bio-based envelopes for building applications. This can be achieved by incorporation of bio-based phase change materials (BPCMs) in wood materials for energy storage in residential buildings. READ MORE

  3. 3. Physical-mechanical properties and natural durability of lesser used wood species from Mozambique

    Author : Alexandre Charifo Ali; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The aim of this study is to assess properties of lesser used/known timbers from Mozambique. The studied species were ncurri (Icuria dunensis Wieringa), ntholo (Pseudolachnostylis maprounaefolia Pax), metil (Sterculia appendiculata K. Schum), namuno (Acacia nigrescens Oliv.) and muanga (Pericopsis angolensis Meeuwen). READ MORE

  4. 4. Thermally Modified Timber : Novel Aspects of Bending Behaviour Towards Grading and Structural Applications

    Author : Joran van Blokland; Stergios Adamopoulos; Anders Olsson; Jan Oscarsson; Mark Hughes; Linnéuniversitetet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; checks; cracks; digital image correlation; four-point static bending; fracture characteristics; grade determining properties; non-destructive testing; Norway spruce; machine learning; outdoor above-ground exposure; timber grading; scanning electron microscopy; scanning of fibre direction; strain distribution; ThermoWood®; weathering; Forestry and Wood Technology; Skog och träteknik; Byggteknik; Civil engineering;

    Abstract : Thermally modified timber (TMT) has gained market share in Europe as an environmentally friendly and durable building material. Unfortunately, TMT products are currently prohibited for use in structural applications as there is insufficient data to estimate the loss in strength due to thermal modification. READ MORE

  5. 5. Wood colour related to kiln drying

    Author : Bror Sundqvist; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood Physics; Träfysik;

    Abstract : Raised temperature in artificial drying has led to some changes of wood products such as colour and strength etc. For special treatment of wood-products with clearly modified properties, among them colour, is often high temperature and steam used industrially. READ MORE
