  1. 1. Modelling and simulation of building components : thermal interaction between multilayer wall and hydronic radiator

    Författare :Christian Brembilla; Thomas Olofsson; Per Sahlin; Persson Leif; Annika Moström; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydronic radiator; multilayer wall; efficiencies of emission; systemanalys; Systems Analysis; engineering science with specialization in microsystems technology; teknisk fysik med inriktningen mikrosystemteknik;

    Sammanfattning : Background and Scope: The scope of this thesis is to investigate the thermal behaviour of building components as hydronic radiator and multilayer walls subjected to dynamic conditions. The modelling and simulation of these building components provide information on how these components thermally interact among each other. LÄS MER

  2. 2. 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.

  4. 4. Some new Hardy-type inequalities on the cone of monotone functions

    Författare :Guldarya Shambilova; Peter Wall; Lars-Erik Persson; Vladimir D. Stepanov; Dorothee Diethild Haroske; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Sammanfattning : This PhD thesis is devoted to the study weighted Hardy-type inequalitieswith quasilinear integral operators on the cone of monotone functions. Thethesis consists of six papers (papers A - F) and an introduction, which givesa brief review of the theory of Hardy-type inequalities and also serves to putthese papers into a more general frame.

  5. 5. Transmission Electron Microscopy of 2D Materials : Structure and Surface Properties

    Författare :Linda Karlsson; Per Persson; Javier Bareno; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transmission Electron Microscopy; Two-dimensional materials; Graphene; MXene; Ti3C2Tx; Low-voltage TEM; Aberration-corrected TEM; monchromated TEM; Scanning transmission electron microscopy; Electron energy loss spectroscopy;

    Sammanfattning : During recent years, new types of materials have been discovered with unique properties. One family of such materials are two-dimensional materials, which include graphene and MXene. These materials are stronger, more flexible, and have higher conductivity than other materials. As such they are highly interesting for new applications, e. LÄS MER
