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

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Gustav Larsson; [2023]
    Nyckelord :organic solar cells; polymer; morphology; film; AFM;

    Sammanfattning : 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.

    Sammanfattning : The EU waste hierarchy includes energy recovery facilities where waste is used as fuel in combined heat- and powerplants. When waste is incinerated can the thermal energy be used in for example, district heating networks and or electricity generation. LÄS MER

  4. 3. Dissolution of Cored Wire in Steel Melt : Optimization of Feeding Rate

    Master-uppsats, KTH/Materialvetenskap

    Författare :Hagen Christian Hagens; [2022]
    Nyckelord :Cored wire injection · light alloy addition · feed rate optimization · inclusions modification · finite difference method;

    Sammanfattning : Calcium treatment is an established operation in the production of steels. Most importantly, it serves to modify detrimental inclusions in the melt for improved castability and superior product properties. Due to calcium’s low melting point and high vapour pressure, its addition to liquid steel is challenging and yields are generally low. LÄS MER

  5. 4. Utredning av behovsstyrt ångtryck på lågtrycksnätet : Maximerad elproduktion vid Stora Enso Skutskärs Bruk

    Master-uppsats,

    Författare :Björn Persson; [2019]
    Nyckelord :turbin; mottryck; optimering;

    Sammanfattning : One of the global sub-goals states that rehabilitation and adaptation of industrial infrastructure is important for making industries more sustainable, with more efficient use of resources by year 2030. Increased energy prices, strict environmental requirements, new control instruments for efficient end use of energy have created an increased desire to reduce energy use and related energy costs.
