  1. 11. A study of optical and structural properties of spin-coated V2O3 thin films on sapphire substrates

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Jennifer Silander; [2022]
    Keywords : Optical properties; transmittance; FTIR spectrometry; scanning electron microscopy; x-ray diffraction; metal-insulator transition; crystalline material; sol-gel; spin-coating; vanadium oxide; infrared light;

    Abstract : Many transition metal oxides exhibit a Metal-Insulator Transition (MIT). This is an interesting phenomenon where the material undergoes a structural phase transition, and the electronic charge is redistributed in the crystal lattice. READ MORE

  3. 12. Automation of carbonyl index calculations for fast evaluation of microplastics degradation

    University essay from KTH/Fysik

    Author : Maja Walfridson; Emma Kuttainen Thyni; [2022]
    Keywords : FTIR; Carbonyl index; Degradation of microplastics; Microplastics; Automation;

    Abstract : The broad use of plastics has resulted in the increase in both production and consequent plastic pollution in the environment. Microplastics, defined as particles < 5 mm, is of special interest because of its wide existence in environment and potential hazards to our ecosystem. READ MORE

  4. 13. Double-layer vs single-layer cryogels as a dye affinity chromatography column, comparison study

    University essay from Lunds universitet/Kemiska institutionen

    Author : Thi Hoai Thu Trinh; [2022]
    Keywords : dye-affinity chromatography; single-layer cryogels; double-layer cryogels; protein purification; bovine serum albumin; biochemistry; Chemistry;

    Abstract : Dye affinity chromatography is one of the chromatography techniques which uses dye as a ligand for protein purification. In this study, single-layer poly(acrylamide-allyl glycidyl ether) cryogel was prepared, which contains free epoxy groups at sub-zero temperature. READ MORE

  5. 14. Evaluation of the effects of four consolidants on matte paint and their ageing

    University essay from Göteborgs universitet/Institutionen för kulturvård

    Author : Angela Caira; [2021-09-14]
    Keywords : matte paint; consolidant; artificial ageing;

    Abstract : This research starts with the analysis of the funeral coat of arms of Pehr Stålhammar, dated 1701, as a case material of matte paint in need of consolidation. This study aims to assess the effect of four consolidants on matte paint and their ageing properties. READ MORE

  6. 15. Microplastics in the Gulf of Bothnia, SwedenA comparison between Österfjärden and Örefjärden.

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Emma Overgaard; [2021]
    Keywords : IR; Microplastic; pollution; polymer composition; surface water; visual characterization;

    Abstract : Microplastics are emerging pollutants in the marine environment, including a range of polymers modified by varying quantities of additives and sorbed pollutants, differing in size, colour, and shape. This study focuses on characterization and quantification through visual characterization of microplastics >300 μm in surface water and at 5-meter depth in the Gulf of Bothnia. READ MORE
