  1. 1. Modelling and simulation of building components thermal interaction between multilayer wall and hydronic radiator

    University dissertation from Umeå : Umeå University

    Author : Christian Brembilla; Umeå universitet.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydronic radiator; multilayer wall; efficiencies of emission; Systems Analysis; systemanalys; Technical Physics; teknisk fysik med inriktningen mikrosystemteknik;

    Abstract : Background and Scope The scope of this thesis is to investigate the thermal behaviour of building components as hydronic radiator and multilayer walls subjected to dynamic conditions. The modelling and simulation of these building components provide information on how these components thermally interact among each other. READ MORE

  4. 4. Dimensional Stability of Paper Influence of Fibre-Fibre Joints and Fibre Wall Oxidation

    University dissertation from Stockholm : KTH

    Author : Per A. Larsson; KTH.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Chemical engineering Chemical process and manufacturing engineering Cellulose and paper engineering; TEKNIKVETENSKAP Kemiteknik Kemisk process- och produktionsteknik Cellulosa- och pappersteknik;

    Abstract : Papper är ett mycket mångsidigt material. Trots detta finns det ett flertal egenskaper som begränsar papperets användbarhet. Ett av de större problemen med cellulosa- och lignocellulosafibrer är att de sänker sin fria energi genom att sorbera vatten, och denna sorption förändrar papperets dimensioner. READ MORE

  5. 5. Development of Non-leaching Antibacterial Approaches on Cellulose-based Substrates and Their Mechanisms

    University dissertation from KTH Royal Institute of Technology

    Author : Chao Chen; KTH.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Layer-by-layer; antibacterial; cellulose materials; Chemical Engineering; Kemiteknik;

    Abstract : The layer-by-layer (LbL) technique is becoming a powerful tool that has been applied in many surface coatings and functionalizations in recent years. It has many advantages including a fast and mild process, the flexibility of choice of substrate, and the easiness to scale-up. READ MORE
