  1. 1. Analys av transparent trä tillverkat genom delignifiering och PMMA-infiltration

    Kandidat-uppsats, KTH/Kemiteknik

    Författare :Hannah Rosell; Tove Tisell Mikkelsen; Nadiya Wattar; Selma Kadric; [2023]
    Nyckelord :Transparent wood; fiber technology; polymer infiltration; delignification; wood chemistry;

    Sammanfattning : Rapporten presenterar en studie där tre trätyper, balsa, ask och björk, fabriceras genom en förutbestämd metod till transparent trä. Detta material har många möjliga applikationer, inklusive energieffektiva byggnader, förpackningar, solceller och elektroniska apparater. LÄS MER

  3. 2. Graphene Based Aqueous Ammonium Dual-Ion Batteries

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Strukturkemi

    Författare :Arvid Sandberg; [2023]
    Nyckelord :Dual ion batteries; materials science; chemistry; organic polymer;

    Sammanfattning : The global transition to renewable energy sources is placing high demands on the development of effective energy storage methods, the most prevalent being batteries. Dual-ion batteries are a new battery technology that takes advantage of the simultaneous intercalation of both cations and anions. LÄS MER

  4. 3. Investigation of acidic chemical recycling of poly(acetal-ester)s

    Magister-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Saga Vesterbacka; [2023]
    Nyckelord :Poly actetal-ester s; Chemical plastic recycling; Hydrolysis; Acidic degradation; Akestra; PHVT; Re-polymerization; Polymer technology; Chemistry;

    Sammanfattning : Plastic recycling is a very relevant topic from both environmental and economic viewpoints. Chemical plastic recycling is a logical solution to the plastic problems, which shows the potential to reduce plastic waste and carbon emissions from burning the plastics. LÄS MER

  5. 4. Finding a suitable and optimal amount of binder for refibering of acoustic boards

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Nardos Wolderufael; [2022]
    Nyckelord :Recycle; Binder; Fiber; Polymer Technology; Chemistry;

    Sammanfattning : With the ambition to contribute to a sustainable development, this project started with aim to recycle fiber boards. The idea behind the project is to take lose fibers that come from waste product or simply just worn out fiber boards, and make them into new fiber boards. In order to achieve this, a binder is needed to hold the boards together. LÄS MER

  7. 5. Optimization of a one-part geopolymerization method for lab-scale, using waste glass wool as a precursor

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Oscar Enander; [2022]
    Nyckelord :Materials chemistry; Geopolymer; Glass wool; Recycling; Curing time; Curing temperature; Cement; Chemistry;

    Sammanfattning : Geopolymers are amorphous inorganic polymeric structures. They are used as binding agents and can be compared to cementitious materials such as ordinary Portland cement. This thesis aims to produce geopolymers from waste glass wool. Today glass wool is found in isolation, both thermal and sound insulation, and it is not being recycled. LÄS MER
