  1. 1. Morphological study of PS/PMMA-matrix on glass, related to vapour pressure, mass-fraction, and size

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Author : Gustav Larsson; [2023]
    Keywords : organic solar cells; polymer; morphology; film; AFM;

    Abstract : The objective of this study is to observe how changing amount or ratio between dried mixes of poly-methyl-methacrylate and poly-styrene change the surface appearance, and how the results might inform future design of Organic photovoltaic cells, whom are based on polymer mixtures and heavenly dependent on the arrangement of polymers. An atomic force microscope was used on glass surfaces coated in a poly-methyl-methacrylate/poly-styrene matrix and dried from either dichloromethane or ethyl-acetate to determine surface appearance.

  3. 2. Qualitative Analysis of Chlorinated Paraffins in Recycled Plastics

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Solal GAUDIN; [2023]
    Keywords : Short chain Chlorinated Paraffins SCCP Medium chain Chlorinated Paraffins MCCP Long chain Chlorinated Paraffins LCCP Recycled plastics Qualitative analysis Bioaccumulation Long range transport Gas Chromatography – Mass spectrometry;

    Abstract : Described in many studies as dangerous for the environment and potentially carcinogenic for humans, Chlorinated Paraffins (CPs) are easily widespread due to their substantial production and use in different products. Previous studies reported the presence of CPs in different plastic polymers. READ MORE

  4. 3. 3D printing of ceramic composites with improved mechanical strength

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Liu Yuchen; [2023]
    Keywords : ;

    Abstract : AbstractCeramic materials have a wide range of applications in many fields, but their fragility limits theiruse in high strength and high stress environments. Therefore, by combining ceramic materialswith reinforcing agents, their mechanical properties can be improved. READ MORE

  5. 4. Developing an Ar milling process to improve the contact quality to InAs nanowires

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

    Author : Chris Mkolongo; [2023]
    Keywords : InAs nanowires; Argon milling; Technology and Engineering;

    Abstract : The aim of this work was to develop a stable and reproducible argon milling process for InAs nanowires to remove the native oxide layer that increases electrical resistance. This was done by identifying a few milling parameters and studying them in relation to the milling rate of silicon dioxide (SiO2). READ MORE

  6. 5. Viscoelasticity of transparent wood-polymer biocomposites : Measuring the time-dependence of a delignified birch and poly(methyl methacrylate) composite’s mechanical properties, using digital image correlation

    University essay from KTH/Materialvetenskap

    Author : Marine Jeanne Debouvry; [2023]
    Keywords : ;

    Abstract : The viscoelastic behavior of a delignified birch and poly(methyl methacrylate) (PMMA) composite was investigated, in an effort to learn more about the mechanical properties of transparent wood-polymer biocomposites. Tensile creep tests with constant load were performed for native wood, non-delignified, and delignified wood-polymer composites. READ MORE
