    Nyckelord :biostimulation; oxygen release compound; ORC; ORM; in situ; toluene; Earth and Environmental Sciences;

    Sammanfattning : It is common that oxygen is a limited factor in microbial decomposition of a substance. Biostimulation with oxygen release compound, increase dissolved oxygen in groundwater and stimulate natural decomposition of petroleum hydrocarbon. LÄS MER

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

    Master-uppsats, KTH/Materialvetenskap

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

    Sammanfattning : 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. Developing Formaldehyde Free Flame Retardant for Cellulose

    Magister-uppsats, Högskolan i Borås/Institutionen Textilhögskolan

    Författare :MD.Abdul Hannan; [2011]
    Nyckelord :cotton cellulose; organophosphorus flame retardant; acetal linkage; low temperature pyrolysis; THC; HRR; char residue; LOI;

    Sammanfattning : Two organophosphorus compounds, namely diethyloxymethyl-9-oxa-10- phosphaphenanthrene-10-oxide (DOPAC) and diethyl (2,2-diethoxyethyl) phosphonate (DPAC) were applied on cotton cellulose to impart non-carcinogenic and durable (in alkaline washing) flame retardant property to it. Some acidic catalysts, sodium dihydrogen phosphate (NaH2PO4), ammonium dihydrogen phosphate (NH4H2PO4) and phosphoric acid (H3PO4), were successfully used to settle acetal linkage between cellulose and flame retardant (FR) compound.
