  1. 1. Surface characterization of 2D transition metal carbides (MXenes)

    Författare :Ingemar Persson; Per Persson; Justinas Palisaitis; Johanna Rosén; Vanya Darakchieva; Vincent Mauchamp; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Research on two-dimensional (2D) materials is a rapidly growing field owing to the wide range of new interesting properties found in 2D structures that are vastly different from their three-dimensional (3D) analogues. In addition, 2D materials embodies a significant surface area that facilitates a high degree of surface reactions per unit volume or mass, that is imperative in many applications such as catalysis, energy storage, energy conversion, filtration, and single molecule sensing.

  2. 2. The Potential and Challenges of the Use of Dynamic Software in Upper Secondary Mathematics : Students’ and Teachers’ Work with Integrals in GeoGebra Based Environments

    Författare :Sanela Mehanovic; Per Jönsson; Morten Blomhøj; Per-Eskil Persson; Morten Misfeldt; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Sammanfattning : An introduction of computer software into mathematics classrooms makes the didactical situation more complex compared with previous learning environments (Blomhøj, 2005). A technological tool becoming a mathematic work tool in the hands of the students is a process that has turned up unexpectedly complex (Artigue, 2002). LÄS MER

  3. 3. Parallel Numerical Procedures for the Solution of Contact-Impact Problems

    Författare :Per Persson; Karl Schweizerhof; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Finite element (FE) simulations of complex problems tend to yield very large models if detailed knowledge of the problem is required. As the model becomes larger, the time needed for solving the problem increases. The solution time is even longer if contact is present in the model. LÄS MER

  4. 4. Electron microscopy of ion implanted silicon carbide

    Författare :Per Persson; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : This thesis investigates structural defects into Silicon Carbide (SiC) in processed Al and B ion implantated samples. Ion implantation is currently the preferred way to introduce impurity atoms into the SiC crystal lattice. The structural defects found was concluded to be extrinsic dislocation loops composed of excess Si interstitials. LÄS MER

  5. 5. Industrial statistics in product development

    Författare :Per Persson; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Product development is recognized as a critical activity in most companies. One important aspect of product development is how to handle different kinds of variation. There are many sources of variation, even at the very beginning of the product development process, there is often variation in what needs are important to different customers. LÄS MER
