  1. 1. Environmental Barrier Coatings to protect Ceramic Matrix Composites in next-generation jet engines

    University essay from Högskolan Väst/Institutionen för ingenjörsvetenskap

    Author : Shivang Parmar; [2023]
    Keywords : Environmental barrier coating; ceramic matric composite; atmospheric plasma spray; suspension plasma spray; thermal cyclic fatigue; Barriärbeläggning; keramisk komposit; atmosfärisk plasmasprutning; suspensionsplasmasprutning; termisk cyklisk utmattning;

    Abstract : Gas turbine engine efficiency needs to be raised in order to decrease fuel consumption, greenhouse gas emissions, and expenses. Efficiency may be improved in two ways: by reducing engine weight and raising intake temperatures. READ MORE

  3. 2. Investigating the Adsorption of Per- and Polyfluoroalkyl Substances on Amine-functionalized Mesoporous Carbons

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : MOJISOLA SALISU; [2023]
    Keywords : Mesoporous carbon; PFOA; PFOS; PFAS; Rose Bengal; Adsorption;

    Abstract : Water pollution is a profound ecological concern, exerting detrimental effects on human well-being, ecological systems, and animal life. Among the emerging contaminants that critically influence water quality and have garnered substantial scientific interest in recent times are per- and polyfluoroalkyl substances (PFAS). READ MORE

  4. 3. Challenges and Metallurgical Benefits of Implementing Metal Additive Manufacturing : A Case Study on Excavator Bucket Teeth Comparing Sand Casting with Additive Manufacturing

    University essay from Mälardalens universitet/Akademin för innovation, design och teknik

    Author : Sam Thai; Michael Thunberg; [2023]
    Keywords : Challenges; Electron Beam Melting; Metal Additive Manufacturing; Metallurgy; Microstructure; Porosity; Qualification; Sand Casting;

    Abstract : Introduction: Production systems go through changes over time and there are different factors driving the change. Metal Additive manufacturing (AM) could be a factor with industries that already havetaken interest in the manufacturing technique. READ MORE

  5. 4. Estimating active layer thickness at the high Arctic study site Zackenberg from remotely sensed ground subsidence

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Lotte Wendt; [2021]
    Keywords : active layer thickness; DInSAR; subsidence; permafrost; Zackenberg; CALM; Earth and Environmental Sciences;

    Abstract : The active layer thickness (ALT) is an indicator of permafrost thaw, which potentially leads to the release of large amounts of greenhouse gases under global warming, and thus could further amplify climate change. The thaw depth of the active layer also governs seasonal surface deformation, caused by the volume change between ice to water, which poses risks for slope stability and infrastructure foundations.

  6. 5. Dustiness Testing and Particle Characterization of CNT-enhanced Concretes

    University essay from Lunds universitet/Ergonomi och aerosolteknologi

    Author : Sara Marsh; [2021]
    Keywords : concrete; dustiness; airborne particles; carbon nanotubes; Technology and Engineering;

    Abstract : The introduction of fibers into concrete is a common way of reinforcing the mechanical properties and preventing cracking. The fibers act as bridges between the composite components and help reduce the porosity. Today, micrometer-sized fibers are widely used, but there is an increased interest in using smaller fibers e.g. READ MORE
