  1. 16. Potential of tall oil pitch as phase change material in lignin-shelled hybrid nanocapsules for thermal energy storage.

    University essay from Mittuniversitetet/Institutionen för kemiteknik

    Author : Helena Viberg Nissilä; [2022]
    Keywords : phase change materials PCM ; tall oil pitch TOP ; lignin; nanocapsules; hybrid material; thermal storage;

    Abstract : A prospect in utilizing thermal energy in development of energy systems is by the useof phase change materials (PCMs). PCMs are materials that can store and releaseenergy during phase changes, e.g. from solid to liquid. READ MORE

  3. 17. Heterogeneous catalytic reactions studied with transient gas supply and event-averaged ambient pressure x-ray photoelectron spectroscopy

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/NanoLund: Centre for Nanoscience

    Author : Qianhui Liu; [2022]
    Keywords : Ambient pressure x-ray photoelectron spectroscopy; Event-averaging; Pd 100 surface structure oscillation; Physics and Astronomy;

    Abstract : CO oxidation over Pd(100) is studied with ambient pressure x-ray photoelectron spectroscopy (APXPS). Cyclic gas composition pulsing of the CO:O2 ratio, combined with a new method using software based event-averaging by image recognition over many pulses, is used to improve the signal-to-noise ratio substantially.

  4. 18. 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

  5. 19. Insights into the burning behaviour of wood in the cone calorimeter

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Ellinor Sanned; [2022]
    Keywords : Wood combustion; fire test; cone calorimetry; heat release rate; char formation;

    Abstract : Climate change and its accompanying environmental issues have caused the building industry to use more environmentally friendly building materials. Wood have always been a buildingmaterial but due to the renewed interest in imparting sustainability and renewability, its usage has increased over the recent years. READ MORE

  6. 20. Upcycle and Repurpose Driven Design : A case study at ReTuna Återbruksgalleria

    University essay from Linköpings universitet/Produktrealisering

    Author : Moa Berglund; [2022]
    Keywords : Climate change; transition; transformation; circular economy; upcycle; furniture design; recycling; repurpose driven design; second hand; mall; circular design; consumption;

    Abstract : How can we use more of the materials and products that have already been produced? At the second hand shopping mall ReTuna in Eskilstuna, where circular flows are a reality, there are still many products going to waste. This master thesis project explores the possibilities of upcycle and repurpose driven design, and by that adding new value to existing products. READ MORE
