  1. 6. Mixed mode loaded adhesive layers : from measurement of material data to analysis of structural behaviour

    Författare :Jia Li Högberg; Högskolan i Skövde; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adhesive layer; mixed mode testing; cohesive law; J-integral; Engineering mechanics; Teknisk mekanik; Teknik; Technology;

    Sammanfattning : In manufacturing of multi-material products, a joining method that is able to cost-effectively assemble components made of dissimilar and similar material, with irregular geometries, is optimal. As an alternative, adhesive bonding is in-creasingly adapted by the industry, which is also used in manufacturing of multi-phase materials. LÄS MER

  3. 7. Anti-Ageing Strategies : How to avoid failure in sodium-ion batteries

    Författare :Le Anh Ma; Reza Younesi; Daniel Brandell; Laurent Duda; Philipp Adelhelm; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sodium-ion batteries; manganese-based cathodes; solid electrolyte interphase; ageing mechanism; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Sammanfattning : In order to move away from fossil fuels, batteries are one of the most important technologies to store energy from renewable sources. The rapid demands of battery applications put pressure on supply chains of raw materials, such as lithium, nickel, copper, aluminium and cobalt. LÄS MER

  4. 8. Li2O2 quantification in non-aqueous Li-O2 batteries with binder-free cathodes

    Författare :Chenjuan Liu; Torbjörn Gustafsson; Martin Sahlberg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The non-aqueous Li-air (Li-O2) battery has been emerging as one of the most promising high-energy storage systems to meet the requirements for electric vehicle applications due to its high theoretical energy density. In order to uncover the underlying electrochemistry and enable an informed battery design, it is crucial to gain a detailed understanding of the cell´s chemical components as well as its behavior during cycling.

  5. 9. Digital information and traditional knowledge : the implementation of GPS collars as a tool in reindeer husbandry

    Författare :Kajsa Kuoljok; Alf Arvidsson; Marianne Liliequist; Ivar Bjørklund; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; reindeer herding; technology; GPS - global positional system; Actor network theory; ethnolgy; Ethnology; etnologi;

    Sammanfattning : This dissertation presents the use of global positioning systems (GPS) navigation devices to monitorthe reindeer within husbandry. The use of the GPS collar in the study area has expanded over theyears. LÄS MER

  7. 10. Calcitonin gene-related peptide in temporomandibular inflammation

    Författare :Joakim Carleson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :CGRP; Calcitonin gene-related peptide; neuropeptides; inflammation; temporomandibular joint; masseter muscle; TMJ; TMD; nociception; scratching; neurogenic inflammation.;

    Sammanfattning : Calcitonin gene-related peptide (CGRP) is an important biological mediator and cell-signalling molecule, involved in modulation of the immune system, inflammatory response and pain modulation. During pain and inflammation, sensory nerves are activated, and sensory neuropeptides such as CGRP is released from peripheral and central nerve endings. LÄS MER
