  1. 1. Studies on Rechargeable Fe-air electrodes in Alkaline electrolyte

    Author : Alagar Raj Paulraj; Yohannes Kiros; Carlos Ponce de León Albarrán; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fe-air battery; Cu Sn-doped nanostructured iron electrodes; Alkaline electrolytes; Bi-functional OER ORR catalyst; perovskite spinel catalyst; NiFeOx; air electrode; Chemical Engineering; Kemiteknik;

    Abstract : Energy storage system is an important component in the energy system based on variable renewable energy sources into the grid. Energy storage system could contribute to decarbonization, energy security, offset the demand and supply of the electricity sector, especially for the electric grid. READ MORE

  2. 2. Colloidal fumed silica and soluble silicates — Interactions and microstructure

    Author : Jonas Nordström; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electrolytes; Infrared spectroscopy; Alkaline sodium silicate; Colloidal stability; Ionic liquids; Gelation; Raman spectroscopy; Photon correlation spectroscopy; Fumed silica; Water glass;

    Abstract : Colloidal dispersions and gels are important material systems with applications in many industrial processes and consumer products. This thesis aims at increasing the understanding of colloidal interactions and the phase transition from a colloidal dispersion to an arrested structure in two systems based on silica. READ MORE

  3. 3. Rechargeable Aqueous Batteries Based on Available Resources : Investigation and Development towards Efficient Battery Performance

    Author : Mylad Chamoun; Dag Noréus; Gunnar Svensson; Jekabs Grins; Ann Mari Svensson; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; rechargeable aqueous batteries; alkaline electrolytes; aqueous sulfate electrolytes; zinc electrodes; manganese dioxide electrodes; iron electrodes; air electrodes; oxygen electrocatalysts; oorganisk kemi; Inorganic Chemistry;

    Abstract : Batteries employing water based electrolytes enable extremely low manufacturing costs and are inherently safer than Li-ion batteries. Batteries based on zinc, manganese dioxide, iron, and air have high energy relevancy, are not resource restricted, and can contribute to large scale energy storage solutions. READ MORE

  4. 4. Structure and Dynamics of Silica Dispersions and Gels

    Author : Jonas Nordström; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; aging; Photon correlation spectroscopy; sodium silicate; lithium electrolytes; water glass; fumed silica; sol-gel transition;

    Abstract : This thesis deal with the sol-gel transition of two quite different systems, both based on silica. The overall aim is to understand what interactions lead to this sol-gel transition and how the structure and dynamics change as a result of this.The first project concern the gelation of water glass, also known as alkaline sodium silicate solutions.

  5. 5. On the bone response to oxidized titanium implants. The role of microporous structure and chemical composition of the surface oxide in enhanced osseointegration

    Author : Young-Taeg Sul; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : Oxidized titanium implants; micro arc oxidation; oxide growth; surface oxide properties; bone; biomechanical tests; histomorphometry; enzyme histochemistry.;

    Abstract : Background: Titanium implants have been widely used clinically for various types of bone-anchored reconstructions. A thin native oxide film, naturally formed on titanium implants contacts with bone tissue and has been considered to be of great importance for successful osseointegration. READ MORE
