1. 1. Antimicrobial materials from cellulose using environmentally friendly techniques

   Författare :Anna Ottenhall; Monica Ek; Josefin Illergård; Orlando Rojas; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Antibacterial; antifungal; cellulosic; mold; bacteria; biobased; bio-based; renewable; insulation; packaging; water treatment; water purification; paper filter; paper; membrane; Antibakteriell; fungicid; mögel; antimögel; pappersfilter; vattenrening; membran; papper; bakterier; cellulosa; förpackning; isolering; förnyelsebar; biobaserade; nya material; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Sammanfattning : The transition to a more biobased society introduces both new opportunities and new challenges as we replace nonrenewable materials with renewable alternatives. One important challenge will be to control microbial growth on materials, both to protect the materials from biological degradation and to prevent the spread of infections and toxins that can cause illness.

3. 2. Determination of the Critical Moisture Level for Mould Growth on Building Materials

   Författare :Pernilla Johansson; Avdelningen för Byggnadsfysik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Crawl space; Fungus; Mould resistance; Wood; Building materials; Mould; Critical moisture level; Attic; Relative humidity; Cyclic conditions; Laboratory method;

   Sammanfattning : The susceptibility to mould growth varies between building materials. The factors that most affect mould growth, the relative humidity (RH) and temperature also vary in different parts of buildings. One way of preventing the growth of mould in buildings is therefore to choose building materials that can withstand the expected conditions. LÄS MER

4. 3. Moisture Buffering in the Indoor Environment

   Författare :Kaisa Svennberg; Avdelningen för Byggnadsfysik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; furniture; textiles; moisture buffering; beds; indoor air; indoor environment; sorption isotherms; field measurements; definition scheme; Technological sciences;

   Sammanfattning : Moisture buffering in the indoor environment is the ability, through absorption and desorption, of surface materials to attenuate the moisture variations of the indoor air. Moisture buffering plays an important role in understanding the risks for biological growth in surface materials in the indoor environment, e.g. LÄS MER

5. 4. Heated air gaps : a possibility to dry out dampness from building constructions

   Författare :Tord af Klintberg; Folke Björk; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Water damage; convection; air gap; building; construction; Building engineering; Byggnadsteknik;

   Sammanfattning : The air gap method is a modification of the common way of building indoor walls and floors. The aim of the method is to make a construction, less fragile to water damage, with air gaps where moisture can be removed with a thermally driven air flow, caused by a heating cable. The thesis includes a number of experimental studies of this method. LÄS MER

7. 5. Surface modification of birch and acetylated birch wood by silicone nanofilaments

   Författare :Haiyan Yin; Magnus Wålinder; Agne Swerin; Andra Dédinaité; Jan Van den Bulcke; KTH; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER
