  1. 1. Nya metoder för fernissaborttagning – En komparativ studie

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Alica Larsson; [2023-11-08]
    Nyckelord :Oil painting; Varnish removal; Evolon® CR; Tissue-gel composite;

    Sammanfattning : In recent years, new varnish removal methods have emerged in conservation, with two notable approaches: the tissue-gel composite method, involving gel-coated tissue material pressed onto varnished surfaces for simultaneous dissolution and binding, and the use of Evolon® CR textile saturated with solvent. Evolon® CR offers an alternative to gels and tissue-gel composites, aiming to eliminate residue from gel thickening agents and the need for mechanical cleaning, while enabling the use of non-polar solvents in a bound form.

  3. 2. Loading tests on composite concrete columns : A comparison between composite columns made of permanent 3DPC formwork filled with SCC and columns made of homogenous SCC

    Master-uppsats, KTH/Betongbyggnad

    Författare :Abdulla Al-Bazarkan; Hussain Alahmad; [2023]
    Nyckelord :;

    Sammanfattning : In order to achieve increased sustainability when casting concrete structures this thesis investigates the possibility of utilizing 3D-printing to construct formwork and digitalize construction. By digitizing construction less workers are needed and therefore less capital. LÄS MER

  4. 3. Analyzing Raw Material Characteristics for Composite and Bio-composite preparation and Assessing Environmental Impacts through LCA

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Lakshay Vashist; [2023]
    Nyckelord :Plastic; Polymers; Composites; Bio-composites; Synthetic Fibers; Natural Fibers; Mechanical Properties; Life Cycle Assessment LCA ; Plast; polymerer; kompositer; biokompositer; syntetiska fibrer; naturliga fibrer; mekaniska egenskaper; livscykelanalys LCA ;

    Sammanfattning : With the population expected to grow dramatically in the future. The existing state of the ecosystem appears to be worse in the future. One of the key culprits that has been wreaking havoc on the ecosystem is the use of plastic that is used to produce composites. LÄS MER

  5. 4. Analysis of a shape morphing structural battery: manufacturing, analytical modeling and numerical simulation

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Alfredo Bici; [2023]
    Nyckelord :;

    Sammanfattning : A reduction in the global use of fossil fuels is necessary when striving for a more sustainable future. One key strategy in the transition from fossil fuels is electrification. This strategy is particularly prominent within the transport sector, where more efficient ways to store electric energy are being pursued. LÄS MER

  7. 5. Mycelium + Wood = <3 : How can I reduce the CO2 impact of a chair?

    Kandidat-uppsats, Linköpings universitet/Malmstens Linköpings universitet

    Författare :Ragnar Brodow; [2023]
    Nyckelord :;

    Sammanfattning : The primary objective of this study is to examine the viability of developing a chair with a significantly reduced carbon footprint. The research explores two distinct approaches for achieving minimal material usage in the construction process: one involving a minimal amount of wood, and the other utilizing solely wooden waste.
