  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. Modeling PFAS Transport in Groundwater - Exploring current approaches and evaluating parameter importance

    University essay from Lunds universitet/Väg- och vattenbyggnad (CI); Lunds universitet/Teknisk geologi

    Author : Clara Eklund; [2023]
    Keywords : PFAS; Groundwater modeling; FEFLOW; Python; Machine learning; Technology and Engineering;

    Abstract : PFAS contamination in drinking water is a current problem, and new regulations for drinking water limits were recently implemented in each member country of the EU in January this year. Understanding the spread of PFAS in groundwater is therefore important to prevent it from reaching drinking water sources. READ MORE

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

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Solal GAUDIN; [2023]
