  1. 1. Design and processing of metal-organic frameworks for greenhouse gas capture

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Evelina Wiksten; [2023]
    Keywords : Metal-organic frameworks; zeolitic imidazolate frameworks; carbon capture; gas adsorption; direct ink writing;

    Abstract : Anthropogenic emission of greenhouse gases has long been suspected to contribute to global warming and climate change. Most greenhouse gases are emitted in a mixture, so efficient methods and materials to separate and capture the gases are in demand in order to reduce emissions. READ MORE

  3. 2. 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. 3. Recycling of Textile and Plastic from an Interior Vehicle Component

    University essay from KTH/Fiber- och polymerteknologi

    Author : Esther Wennerstrand; [2021]
    Keywords : Polycarbonate; ABS; poly ethylene terephthalate ; mechanical recycling; chemical recycling; Polykarbonat; ABS; polyetylentereftalat; mekanisk återvinning; kemisk återvinning;

    Abstract : På grund av den rådande klimatförändringen och de globala problem som plast orsakar i miljön blir det allt viktigare att dagens linjära materialanvändning ändras till en cirkulär användning. Inom fordonsindustrin har kravet på ökad tillgänglighet och kvalitet på återvunna material identifierats. READ MORE

  5. 4. A Comparative LCA study on the refurbishment of quays with induced mineral deposition technology

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Remy Prame Joseph Jerald; [2020]
    Keywords : Refurbishment; Induced mineral deposition; Life cycle assessment; Climate change impact; Global warming potential;

    Abstract : A quay is a structure which is constructed along the shoreline for docking purposes. When the quay is constructed using reinforced concrete, damage over time happens under the combined action of chemical and mechanical corrosion of the varied materials. READ MORE

  6. 5. Designing a Heat Treatment to Achieve Ductile Advanced High Strength Steels

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Abdellatif Laarich; [2020]
    Keywords : Heat treatment; Quenching and Partitioning; Austempering; Quenching and Tempering; High Aluminum Steel; Strenx 700MC; Ductility; Strength;

    Abstract : Heat treatment is a way to significantly change materials properties. When presented with materials that lack certain mechanical properties, it is possible to change its chemical properties and microstructures by applying heat. This can help achieve better yield strength, ductility and toughness. READ MORE
