  1. 1. The effectivity of vacuum impregnation with glycerol and secondary metabolites on electroporated arugula leaves to improve freezing stability.

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Oscar de Kuijer; [2021]
    Keywords : Pulsed electric field PEF; Arugula; Electroporation; Secondary metabolites; Glycerol; Food engineering; Livsmedelsteknik; Technology and Engineering; Agriculture and Food Sciences;

    Abstract : Freeze damage is a common issue in many food items. The cellular dehydration caused by freezing can be prevented through addition of a cryoprotectant. Research has shown that it is possible to improve the freezing tolerance of plant materials by addition of cryoprotectants, which forms hydrogen bonds with water molecules. READ MORE

  3. 2. Analysis of Heating Processes for the Production of Bipolar Plates in PEM Fuel Cells

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : LASSE MATTHIAS REINPOLD; [2020]
    Keywords : ;

    Abstract : Polymer electrolyte membrane fuel cells (PEMFCs) are a promising alternative to combustion engines and batteries in vehicles. PEMFCs are more efficient than combustion engines, and cars powered by PEMFCs tend to have longer ranges than battery powered cars and has a short fuelling time. READ MORE

  4. 3. Accelerated degradation of bipolar plates in the PEMFC

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Marcus Eriksson; [2016]
    Keywords : ;

    Abstract : The aging of bipolar plates in the polymer electrolyte membrane fuel cell was evaluated using different accelerated degradation tests. From previous studies, it is well known that the startups and shutdowns of a polymer electrolyte membrane fuel cell is the primary cause of fuel cell component degradation. READ MORE

  5. 4. Development of Wet Electrostatic Precipitator for Generation of Nanoparticle-Protein Solution

    University essay from Lunds universitet/Ergonomi och aerosolteknologi

    Author : Julia Adner; [2015]
    Keywords : WESP; Nanoparticle; bioligical identity; protein solution; Technology and Engineering;

    Abstract : To examine nanoparticle toxicity there is a need to produce defined nanoparticles dispersed in a colloidal suspension. Such a solution could also be interesting for other fields such as nano-medicine. In order to disperse the particles in the liquid there are often surfactant added to the process that alternates the surface of the particles. READ MORE

  6. 5. Split of sodium and sulfur in a Kraft mill and internal production of sulfuric acid and sodium hydroxide

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Helena Lundblad; [2012]
    Keywords : LignoBoost; electrodialysis; salt split; bipolar membrane; internal production;

    Abstract : The removal of lignin in a Kraft pulp mill, with the aim to utilize the lignin as more value added green product than just firing lignin in black liquor, is possible with a LignoBoost plant. The LignoBoost plant uses sulfuric acid in the process and this results in an increased net input of sulfur to the pulp mills recovery cycle. READ MORE
