    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; children; generations; species; the environment; appearance; temporality; political action; the acting body-subject; school strike for the climate; Arendt; Merleau-Ponty; Child and Youth Science; barn- och ungdomsvetenskap;

    Sammanfattning : The thesis brings together childhood studies and the problems of environmental degradation and climate change. It focuses on intergenerational and interspecies relations and aspects connected to environmental sustainability. LÄS MER

  3. 27. Cholesterol and apolipoprotein E in suicidal behavior

    Författare :Peter Asellus; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Introduction: Low cholesterol has repeatedly been associated with an increased risk of suicidal and violent behavior. The increase in risk is believed to be associated with alterations in serotonergic signaling, which is associated with low cholesterol. LÄS MER

  4. 28. Insights into Stability Aspects of Novel Negative Electrodes for Li-ion Batteries

    Författare :Hanna Bryngelsson; Kristina Edström; Stefania Panero; Uppsala universitet; []
    Nyckelord :Inorganic chemistry; Li-ion batteries; anode materials; Sb; Cu2Sb; electrodeposition; Oorganisk kemi;

    Sammanfattning : Demands for high energy-density batteries have sharpened with the increased use of portable electronic devices, as has the focus global warming is now placing on the need for electric and electric-hybrid vehicles. Li-ion battery technology is superior to other rechargeable battery technologies in both energy- and power-density. LÄS MER

  5. 29. Operando Characterisation of Lithium–Sulfur Batteries

    Författare :Yu-Chuan Chien; Daniel Brandell; Matthew Lacey; Paul Shearing; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lithium–sulfur batteries; operando characterisation; intermittent current interruption; X-ray diffraction; small-angle scattering; electrochemical impedance spectroscopy; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Sammanfattning : Lithium–sulfur (Li–S) batteries have been under the spotlight of research on electrochemical energy storage systems, primarily owing to their high theoretical specific energy (2552 Wh kg-1). So far, Li–S cells on the market have presented a specific energy of 400 Wh kg-1, which is superior to many commercial alternatives, but far below the theoretical value. LÄS MER

  7. 30. 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
