  1. 1. Dissonant Voices : Philosophy, Children's Literature, and Perfectionist Education

    Författare :Viktor Johansson; Klas Roth; Nicholas C. Burbules; Martin Gustafsson; Paul Standish; Stockholms universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Dissonance; Philosophy; Education; Perfectionism; Children s Literature; Childhood; Cavell; Wittgenstein; Educational Science; pedagogik med inriktning mot utbildningsvetenskap;

    Sammanfattning : Dissonant Voices has a twofold aspiration. First, it is a philosophical treatment of everyday pedagogical interactions between children and their elders, between teachers and pupils. LÄS MER

  2. 2. Highly Concentrated Electrolytes for Lithium Batteries : From fundamentals to cell tests

    Författare :Viktor Nilsson; Kristina Edström; Patrik Johansson; Erik Berg; Chalmers University of Technology; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Li-ion battery; SEI; Highly concentrated electrolyte; Al corrosion; Li metal battery;

    Sammanfattning : The electrolyte is a crucial part of any lithium battery, strongly affecting longevity and safety. It has to survive rather severe conditions, not the least at the electrode/electrolyte interfaces. LÄS MER

    Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Highly concentrated electrolyte; Al dissolution; ion transport; SEI; Li-ion battery; Li metal battery; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Sammanfattning : The electrolyte is a crucial part of any lithium battery, strongly affecting longevity and safety. It has to survive rather severe conditions, not the least at the electrode/electrolyte interfaces. LÄS MER

  4. 4. Quantum Dot Solar Cells: Towards Environmentally Friendly Materials

    Författare :Viktor A. Öberg; Erik Johansson; Muhammet S. Toprak; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Quantum dots; Nano-crystals; Energy conversion; Solar cells; Quantum dot solar cells; Low toxicity; Silver Sulfide; Silver Bismuth Sulfide; Lead Sulfide; Chemistry with specialization in Physical Chemistry; Kemi med inriktning mot fysikalisk kemi;

    Sammanfattning : To decrease the world’s energy dependence on fossil fuels, energy production and specifically electricity production needs to shift to more sustainable alternatives. One such alternative is solar cells as they directly convert energy emitted from the sun into electricity. LÄS MER

  5. 5. Thermal adaptation along a latitudinal gradient in damselflies

    Författare :Viktor Nilsson-Örtman; Frank Johansson; Karl Gotthard; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Growth rate; metabolic theory of ecology; universal temperature dependence; environmental gradients; thermal performance; thermal sensitivity; environmental variability; optimality theory; life history; acclimation; size structure; competition; cannibalism; intraguild predation;

    Sammanfattning : Understanding how temperature affects biological systems is a central question in ecology and evolutionary biology. Anthropogenic climate change adds urgency to this topic, as the demise or success of species under climate change is expected to depend on how temperature affects important aspects of organismal performance, such as growth, development, survival and reproduction.
