  1. 1. ZrN based Nanostructured Hard Coatings Structure-Property Relationship

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Phani Kumar Yalamanchili; Magnus Odén; Naureen Ghafoor; Emilio Jiménez-Piqué; Jon Andersson; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Ever since the hard coatings have been introduced, there has been a constant push for better mechanical properties, which motivates for deeper understanding of the microstructure-mechanical properties correlation. The aim of this thesis is to extend the knowledge on how microstructural variation influences the deformation, fracture and wear behavior of ZrN based nanostructured coatings. LÄS MER

  3. 3. Towards alkali-stable polymers and hydroxide exchange membranes functionalized with alicyclic quaternary ammonium cations

    Detta är en avhandling från Centre for Analysis and Synthesis, Department of Chemistry, Lund University

    Författare :Thanh Huong Pham; [2019]
    Nyckelord :hydroxide exchange membrane; fuel cell; alicyclic quaternary ammonium; alkali-stable; high hydroxide conductivity; structure-property relationship;

    Sammanfattning : In the current work, cationic polymers functionalized with N-alicyclic quaternary ammonium (QA) cations were synthesized and characterized as potential hydroxide exchange membranes (HEMs) for application in fuel cells. Three different polymers, namely poly(arylene ether sulfone), spiro-ionene and poly(arylene alkylene), were explored as polymer backbones for the HEMs. LÄS MER

  4. 4. Exploring N-alicyclic quaternary ammonium functional polymers as hydroxide exchange membranes

    Detta är en avhandling från Centre for Analysis and Synthesis

    Författare :Joel Olsson; [2020]

    Sammanfattning : As the global power generation is shifted toward renewable and intermittent sources, the importance of fuel cells and other energy storage and conversion devices is continually increasing. However, many of these technologies are still under development and further research is necessary before they can be implemented. LÄS MER

  5. 5. Experimental Studies of Deformation Structures in Stainless Steels using EBSD

    Detta är en avhandling från KTH Royal Institute of Technology

    Författare :Karin Yvell; KTH.; Högskolan Dalarna.; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EBSD; Austenitic stainless steels; Duplex stainless steel; In situ tensile test; Grain boundaries; Grain rotation; Grain size distribution; Texture; Strain hardening; Structure-property relationship; High strain rate; Wire rod rolling; Roll forming; Steel Forming and Surface Engineering; Stålformning och ytteknik;

    Sammanfattning : In this thesis, the focus has been the study of deformation structures in stainless steels by using electron backscatter diffraction (EBSD). Via increased knowledge of the evolution of the substructure during deformation, the design and control of the manufacturing process can be improved. LÄS MER
