  1. 11. 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.

  3. 12. Synthesis and transport properties of 2D transition metal carbides (MXenes)

    Författare :Joseph Halim; Michel Barsoum; Lars Hultman; Per Eklund; Johanna Rosén; Martin Magnuson; Jun Lu; Christina Birkel; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Since the isolation and characterization of graphene, there has been a growing interest in 2D materials owing to their unique properties compared to their 3D counterparts. Recently, a family of 2D materials of early transition metal carbides and nitrides, labelled MXenes, has been discovered (Ti2CTz, Ti3C2Tz, Mo2TiC2Tz, Ti3CNTz, Ta4C3Tz, Ti4N3Tz among many others), where T stands for surface-terminating groups (O, OH, and F).

  4. 13. Environmental factors selecting for predation resistant and potentially pathogenic bacteria in aquatic environments

    Författare :Peter Mathisen; Agneta Andersson; Johanna Thelaus; Mats Forsman; Anders Sjöstedt; Tron Frede Thingstad; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Eutrophication; productivity; predation pressure; predation-resistant bacteria; pathogens; Francisella tularensis; adaptation; biomarker; oligotyping;

    Sammanfattning : The long history of co-existence of bacteria and their protozoan predators in aquatic environments has led to evolution of protozoa resistant bacteria (PRB). Many of these bacteria are also pathogenic to humans. LÄS MER

  5. 14. Synthesis and characterization of two- and three-dimensional nanolaminated carbides

    Författare :Quanzheng Tao; Johanna Rosén; Per O A Persson; Amit Keren; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis is focused towards the synthesis and characterization of novel nanolaminated materials in primarily bulk (powder) form. Of particular interest is magnetic materials, or laminates that can be used as precursor for two-dimensional (2D) materials. LÄS MER

  7. 15. Acoustic Platform for MXene Synthesis and Electrochemical Behaviour of i-MXenes in Aqueous Electrolytes

    Författare :Ahmed El Ghazaly; Johanna Rosén; Ahmed Etman; Husam N. Alshareef; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Surface Acoustic Waves; MXene; i-MXene; Supercapacitor;

    Sammanfattning : Climate Change is believed to be the greatest global challenge and on its forefront is the topic of energy. While being of extreme importance, debates over energy have become a normality. LÄS MER
