  1. 1. Nya behandlingsmetoder för PFAS och analys av potentialen att tillämpa dem för in-situ sanering

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Carl-Magnus Mårtensson; [2023]
    Nyckelord :PFAS; AFFF; remediation; in situ; PFAS; AFFF; sanering; in situ;

    Sammanfattning : Per- och polyfluoroalkylämnen (PFAS) är i enkla termer fluorerade kolväten som har använts i ett flertal produkter på grund av deras unika förmåga att vara vatten- och smutsavstötande, värmetåliga samt skiktbildande. PFAS har släppts ut i naturen på flera olika sätt. LÄS MER

  3. 2. Microstructural and Micro-Mechanical Characterization of As-built and Heat-treated samples of HASTELLOY X produced by Laser Powder Bed Fusion Process

    Master-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Onimisi Sanni; [2022]
    Nyckelord :As-built Hastelloy X blocks; Laser powder bed fusion LPBF ; Solution heat-treatment; Disrupted epitaxial growth; Melt Pool Boundaries MPB ; Grain Boundaries GB ; Precipitates; In-situ microtensile testing; microhardness; Mechanical properties; Twin grain boundary fractions;

    Sammanfattning : Microstructure and micro-mechanical characterization of as-built and heat-treated samples of Hastelloy X produced by laser powder bed fusion (LPBF) process has been carried out in this study. As-built LPBF blocks were solution heat-treated at 1177°C and 1220°C followed by fast cooling. LÄS MER

  4. 3. Dioxin i mark : En undersökning kring saneringsmetoder in-situ och on-site.

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

    Författare :Anton Axelsson; [2022]
    Nyckelord :Dioxin in soil; Dioxin i mark;

    Sammanfattning : Dioxins are among the most toxic substances known to man. Dioxins are hydrophobic organic molecules that accumulate in the food chain and can cause cancer and reproductive difficulties for both animals and humans. A common method for remediating contaminated soil is excavation and transporting the masses to a landfill site. LÄS MER

  5. 4. In Situ Heating During XRD Measurements as a Method to Study Recrystallisation of Aluminium Alloy AA3003

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Louise Bäckström; [2018]
    Nyckelord :In situ XRD; in situ heat treatment; recrystallisation; rolled aluminium; AA3003;

    Sammanfattning : Recrystallisation is an important topic in the metal industry since the process may drastically alter the properties of the materials subjected to it. By controlling the recrystallisation process, the material properties can be adjusted as desired, which could lead to stronger materials and hence lighter constructions, decreasing our material consumption.

  7. 5. Thermodynamic Equilibrium Prediction of Corrosion Tendency in Fluidized-Bed Combustion of Solid Waste

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Aida Hosseinian; [2017]
    Nyckelord :Waste to Energy; Fluidized Bed Boiler; Combustion; Corrosion; Factsage; Chemical Fractionation; Waste-derived Fuel;

    Sammanfattning : Global warming and air pollution are two issues of greatest concerns to human life in recent years. Environmental concerns and econimal/political independency of fossil fuels have been the driving force of developing interest in renewable resources of energy for many countries. LÄS MER
