  1. 1. Electrochemical oxidation of PFAS in soil conditions : Using Boron-doped diamond electrodes and iron electrodes

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

    Author : Alexander Öhberg; [2022]
    Keywords : PFAS ELECTROCHEMICAL OXIDATION IN-SITU DESTRUCTION MINERALISATION REMOVAL;

    Abstract : Per- and polyfluoroalkyl substances (PFAS) are a rising topic in the field of contaminated sites around the world, with destruction of these being an area in dire need of innovation. Previous experiments of destructive character have been proven efficient using boron doped diamond electrodes (BDD) in small scale electrochemical cells. READ MORE

  3. 2. In-situ Reduction by Incorporating H2 Filled Hollow Glass Microspheres in PM HIP Capsules

    University essay from KTH/Materialvetenskap

    Author : Emil Strand; [2018]
    Keywords : Hot isostatic pressing; hollow glass microspheres; powder metallurgy; oxide reduction; surface oxides; hydrogen;

    Abstract : For many metal components the presence of hard, non-metallic inclusions such as oxides lowers the impact toughness by acting as fracture initiation points and easing crack propagation. In components produced by powder metallurgy hot isostatic pressing (PM HIP), oxides often form a continuous network of small, spherical inclusions after consolidation at the prior particle boundaries (PPB).

  4. 3. Mineral Chemistry and Parageneses of Oxyborates in Metamorphosed Fe-Mn Oxide Deposits

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Zacharias Enholm; [2016]
    Keywords : Oxyborates; in situ boron analysis; microchemical analysis; Raman analysis; Fe-Mn oxide deposits; Långban; Nordmark; Jakobsberg; Oxyborater; in situ boranalys; mikrokemisk analys; Ramananalys; Fe-Mn-oxidmalmer; Långban; Nordmark; Jakobsberg;

    Abstract : Oxyborate minerals can represent the most important sink for boron in silica-undersaturated mineralised systems such as those of the Långban-type. Yet, their distribution, characteristics and parageneses are still not completely known. READ MORE
