  1. 21. Quantification of the Performance of Algorithms for spectra Baseline Correction

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Författare :Ruijue Huang; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Spectroscopy serves as a vital tool in both scientific research and industrial applications. In spectral analysis, baseline correction is important in order to be able to efficiently extract essential features. LÄS MER

  3. 22. THE GOTHENBURG COLOURISTS - Analysis of selected works by Karin Parrow, Ivan Ivarsson and Ragnar Sandberg

    Master-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Sebastian Karlsson; [2022-11-28]
    Nyckelord :Gothenburg; colourists; pigment; analysis; Göteborg; Kolorister; Karin Parrow; Ivan Ivarsson; Ragnar Sandberg;

    Sammanfattning : ABSTRACT Paintings from three selected Gothenburg colorists, Karin Parrow, Ivan Ivarsson and Ragnar Sandberg were analysed to gain insight into their use of colour. The Gothenburg colorists refers to a group of artists who were active in the Gothenburg area and west coast of Sweden, most of them had studied under Tor Bjurström (1888-1966) at the Valand Academy of art during the 20s.

  4. 23. A GREENER SOLUTION Investigating the potential use of Green Solvents to remove cellulose nitrate lacquer from silver objects

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Borén Evelina; [2022-07-05]
    Nyckelord :Sustainable Conservation; Green Solvents; Cellulose Nitrate; Lacquer; Coating; Silver;

    Sammanfattning : This thesis investigates the performance of non-hazardous solvent substitutes, so called “Green Solvents", for the removal of aged and unaged cellulose nitrate lacquer from silver surfaces. Literature research and preliminary tests resulted in four solvents of interest: ethyl acetate, ethyl lactate, propylene carbonate and dimethyl carbonate. LÄS MER

  5. 24. The Influence of Pigment Additives on the Barrier Properties of Dispersion Coatings

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Malin Eriksson; [2022]
    Nyckelord :dispersion coating; paper products; pigment; sustainable development; circular economy; Dispersionsbarriär; pappersprodukter; pigment; hållbar utveckling; cirkulär ekonomi;

    Sammanfattning : Att minska plastavfall och uppmuntra återvinning har fått hög prioritet i många affärsverksamheter och olika typer av regleringar implementeras för att minska den negativa påverkan av plastanvändningen. Papper och kartong består i huvudsak av cellulosa som har många egenskaper som är essentiella för en hållbar ekonomi (t.ex. LÄS MER

  7. 25. Development of alkaline earth metal-based, metal-organic frameworks for greenhouse gas sorption

    Master-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Ali Maghsoodpoor; [2022]
    Nyckelord :Metal-organic Framework; gas sorption;

    Sammanfattning : Metal-organic frameworks (MOFs) constructed from metal atoms connected by organic linkers have received extensive attention for greenhouse gas separation in the past decades. Moreover, their large surface area makes them a promising candidate as adsorbents for gas sorption. LÄS MER
