  1. 11. Biomimetically improved materials comprising microfibrillated cellulose

    Master-uppsats, Umeå universitet/Kemiska institutionen

    Författare :Cornelia Byström; [2021]
    Nyckelord :;

    Sammanfattning : Microfibrillated cellulose (MFC) is a renewable, cellulosic material mainly producedfrom wood fibers, which are found in the secondary cell walls of plant cells. With theincreased demand for renewable biopolymer films in packaging, MFC has emerged asa potential alternative to non-renewable polymer films. LÄS MER

  3. 12. Evaluation of electrospun lignin/polyvinyl alcohol/cellulose nanofiber mats

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Lisa Johansson Carne; [2021]
    Nyckelord :Electrospinning; lignin; polyvinyl alcohol; cellulose nanofiber; wound dressing;

    Sammanfattning : Polymeric electrospun nanofiber mats have recently emerged as a promising alternative to conventional wound dressings for non-healing wounds. Its large surface area, porosity and scalability are only a few of the promising characteristics of electrospun nanofibers. LÄS MER

  4. 13. Design of column bases concerning bending and shear nibs

    M1-uppsats, KTH/Byggteknik och design

    Författare :Rodi Kay; [2021]
    Nyckelord :Column bases; Pelarfötter;

    Sammanfattning : The purpose of the thesis is to find out how to design column bases with conventional methods presented by European standards and codes, but above all from the Steel Construction Institute's handbook on structural joints and compare it with finite element analyses. However, today there are no good instructions for how column bases exposed to multiaxial bending should be designed, where assumptions based on structural mechanics also was compared with computer tools.

  5. 14. Concrete reinforced with FRP rebars : Evaluation of durability and behaviour in the Service Limit State (SLS)

    Master-uppsats, Luleå tekniska universitet/Byggkonstruktion och brand

    Författare :David Ottosson; [2021]
    Nyckelord :GFRP; Durability; SLS; Atena;

    Sammanfattning : One of the most common building materials is concrete and it has been for a long time. To overcome its low tensile capacity concrete structures are normally reinforced with steel rebars. LÄS MER

  7. 15. En jämförelse mellan TDOK 2013: 0267 version 4.0 och version 5.0 : Bärighetsberäkning för en befintlig bro

    M1-uppsats, KTH/Byggteknik och design

    Författare :Tolga Atanasov; Marge Deghlawi; [2021]
    Nyckelord :;

    Sammanfattning : Trafikverket tog beslut den 15:e juni 2018 att övergå från TDOK 2013:0267 Bärighetsberäkningar version 4 till version 5. I version 4 föreskrev regelverket att Boverkets handbok om betongkonstruktioner, som förkortas till BBK 04, ska följas vid bärighetsberäkningar för broar. LÄS MER
