  1. 1. Effect of mixing time and mixing rate on the evolution of powderproperties for binary adhesive mixtures

    University essay from Uppsala universitet/Institutionen för farmaceutisk biovetenskap

    Author : Noveen Muslih Sadullah; [2024]
    Keywords : Adhesive mixture; mixing time; mixing rate; Budesonide; Lactopress SD;

    Abstract : Dry powder inhalers (DPIs) are often used to deliver drugs to the lungs when treating respiratory diseases. Inhalation powders are often formulated as adhesive mixtures which is the main formulation type used for dry inhalation powders of pharmaceuticals. READ MORE

  3. 2. 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.

  4. 3. Synthesis and Characterization of Materials for Carbon Based Hybrid Asymmetric Supercapacitor Electrodes

    University essay from KTH/Tillämpad fysikalisk kemi

    Author : Avital Cherednik; [2023]
    Keywords : Supercapacitor; hybrid supercapacitor; metal oxide nanoparticles; carbon electrodes; ionic liquid; Superkondensator; hybrid superkondensator; metaloxid nanopartiklar; kolelektroder; jonvätska;

    Abstract : Superkondensatorer är energilagringsenheter som har uppmärksammats mer under det senaste decenniet. Några av de fördelar som dessa enheter har varit är lagring av hög effekttäthet, förlängda livscykler och snabba laddnings- och urladdningstider. READ MORE

  5. 4. Influence of pulsing on PVD TiAlN coating microstructure and mechanical properties : Master thesis project on the impact of deposition parameters on performance and properties of PVD titanium aluminum nitride.

    University essay from Karlstads universitet

    Author : Marcus Roseen; [2023]
    Keywords : ;

    Abstract : This thesis investigates the influence of pulsing on the mechanical properties of PVD TiAlN coatings. The thesis focuses on defects caused by droplets during the arc-evaporation technique by altering the duty time, which affects mechanical properties. READ MORE
