  1. 1. Decarbonising the Stainless Steelmaking through Alloy Solutions

    Författare :Wenjing Wei; Pär Jönsson; Peter Samuelsson; Birat Jean Pierre; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steel; optimization; raw material; process; quality; decarbonisation; rostfritt stål; optimering; material; process; kvalitet; avkarbonisering; Materials Science and Engineering; Teknisk materialvetenskap;

    Sammanfattning : To reach the goal of the Paris Agreement, the reduction of greenhouse gas emissions (GHG)is becoming one of the most pressing issues in the world today. Unlike most other sectors, thestainless steel industry has a significantly higher burden from upstream emissions comparedto operational emissions. LÄS MER

  3. 2. Latent Heat Thermal Energy Storage for Indoor Comfort Control

    Författare :NingWei Justin Chiu; Viktoria Martin; Motoi Yamaha; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Energy Storage; Phase Change Material; Indoor Comfort; Heat Transfer; Termisk Energilagring; Fasändringsmaterial; Inomhuskomfort; Värmeöverföring;

    Sammanfattning : Equating Earth’s existence to 24 hours, we, the Homo sapiens, came about in the last four seconds. Fossil fuel came to our knowledge with mass extraction dating from the Industrial Revolution two centuries ago, in other words 4 milliseconds out of Earth’s 24-hour equivalent lifetime. LÄS MER

  4. 3. Phase Equilibrium-aided Design of Phase Change Materials from Blends : For Thermal Energy Storage

    Författare :Saman Nimali Gunasekara; Viktoria Martin; Justin NingWei Chiu; Torsten Fransson; Ana Ines Fernandez; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal energy storage TES ; phase change material PCM ; phase diagram; congruent melting; compound; solid solution; eutectic; peritectic; Energy Technology; Energiteknik; Teknisk materialvetenskap; Materials Science and Engineering; Chemical Engineering; Kemiteknik;

    Sammanfattning : Climate change is no longer imminent but eminent. To combat climate change, effective, efficient and smart energy use is imperative. Thermal energy storage (TES) with phase change materials (PCMs) is one attractive choice to realize this. LÄS MER

  5. 4. SPECT Imaging using Pinhole Collimation : System Design and Simulation Studies for Pre-Clinical and Clinical Imaging

    Författare :Mikael Peterson; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pinhole SPECT tomography; Nuclear medicine imaging; Monte Carlo-based image reconstruction;

    Sammanfattning : The focus of this dissertation is the use of pinhole collimation in Nuclear Medicine. A pinhole is a single aperture in an opaque material that is placed between the detector and source of interest, and photons must pass through the hole to reach the detector. The choices of pinhole parameters, e.g. LÄS MER

  7. 5. Use of tyre shreds in civil engineering applications : technical and environmental properties

    Författare :Tommy Edeskär; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics;

    Sammanfattning : End-of-life tyres are a disposal problem regarding the large volumes produced every year. Tyre shreds are primarily produced to reduce the transportation volumes of end-of-life tyres after collection. LÄS MER
