  1. 1. Toward Safer Energy Storage Solution by Development of Fluorine-Free Battery Electrolyte

    Författare :Elham Hosseini Bab Anari; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; sodium-ion batteries SIBs ; aqueous electrolyte; lithium-ion batteries LIBs ; safer electrolyte; fluorine-free salt;

    Sammanfattning : Portable electronic devices such as mobile phones, laptops, cameras and electronic vehicles (EVs) which contain lithium-ion batteries (LIBs), are indispensable part of our modern society. The safety of conventional electrolytes of LIBs, composed of fluorinated lithium salts and organic solvents is the source of some concerns. LÄS MER

  3. 2. Safety in the making : studies on the discursive construction of risk and safety in the chemical industry

    Författare :Joel Rasmussen; Birgitta Höijer; Åsa Kroon Lundell; Mark Elam; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; safety; risk; occupational health and safety; organizations; chemical industry; discourse; discursive practices; discursive strategies; power; governmentality; responsibilization; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Media and communication studies; Medie- och kommunikationsvetenskap; Media and Communication Studies; Medie- och kommunikationsvetenskap;

    Sammanfattning : This compilation thesis aims to analyse how risk and safety are constructed, reproduced, and negotiated by communicative means in safety-critical workplaces. It conceptualizes these communicative moments of shaping and reshaping risk and safety as enmeshed in multiple forms of governing. LÄS MER

  4. 3. Studies on Rechargeable Fe-air electrodes in Alkaline electrolyte

    Författare :Alagar Raj Paulraj; Yohannes Kiros; Carlos Ponce de León Albarrán; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; 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;

    Sammanfattning : 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. LÄS MER

  5. 4. Complexation of Thorium with Phosphates and Silicates under Repository Conditions

    Författare :Andreas Knutsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; AKUFVE; Liquid-liquid extraction; Silicates; Complexation; Stability Constants; Thorium; Phosphates;

    Sammanfattning : In order to make reliable performance assessments of the safety for planed underground repositories for spent nuclear fuel large amounts of chemical thermodynamical data is needed. In some cases the databases used for modeling the migration behavior of radionuclides in groundwater is missing data. LÄS MER

  7. 5. Mobilization and Management of Tellurium in Severe Accident Scenarios

    Författare :Anna-Elina Pasi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nuclear; gamma irradiation; source term; severe accident; tellurium;

    Sammanfattning : Safety is one of the highest priorities in any industry. In the nuclear industry, safety is in the essence since in case of a nuclear accident, the consequences can be long-lasting, hazardous, and devastating to the public, environment, and the industry. LÄS MER
