  3. 7. Liquid-Phase Exfoliation of Two-Dimensional Materials : Applications, deposition methods and printed electronics on paper

    Författare :Viviane Forsberg; Magnus Norgren; Luis Miguel Pereira Nunes; Mittuniversitetet; []
    Nyckelord :molybdenum disulfide MoS2 ; transition metal dichalcogenide TMD ; thin films; inkjet printing; 2D inks; liquid-phase exfoliation; shear exfoliation; printed electronics; organic electronics; PEDOT:PSS; photoresponse; photocurrent; cathodoluminescence;

    Sammanfattning : After the unprecedented success of graphene research, other materials that can also be exfoliated into thin layers, like Transition metal dichalcogenides (TMDs) such as molybdenum disulfide (MoS2), have also become the subjects of extensive studies. As one of the most promising methods for large scale production of such materials, liquid-phase exfoliation (LPE) has also been the subject of extensive research and is maturing as a field to the point that devices using additive manufacturing and printed nanosheets are often reported.

  4. 8. Kinetic Measurements Using Nanoplasmonic Sensing

    Författare :Markus Schwind; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sn Nanoparticles; Sensing; Localized Surface Plasmon Resonances; Particle Plasmon; Metal Oxidation; Metal Corrosion; Solid-Liquid Phase Transition; Kinetics; Al Nanoparticles;

    Sammanfattning : In this thesis the nanoplasmonic sensing technique was used to study kinetics of (i) the oxidation of Al nanoparticles in air and water and (ii) the solid-liquid phase transition in Sn nanoparticles. The nanoplasmonic sensing technique detects changes of the localized surface plasmon resonance (LSPR) in metal nanoparticles. LÄS MER

  5. 9. Subvalent Cluster Compounds and Synthesis in Alternative Reaction Media

    Författare :Josefin Åkerstedt; Lars Kloo; Mats Johnsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metal cluster; Zintl ion; metal-organic sandwich complex; ionic liquid; X-ray diffraction; spectroscopy; crystal structure; Inorganic Chemistry;

    Sammanfattning : With the aim of finding alternative reaction media for the synthesis of subvalent main group and transition metal cluster compounds, traditionally made through solid state reactions or in superacidic media, different alternative reaction media have been explored in this work. Room-temperature ionic liquids are amongst the more unconventional reaction media used. LÄS MER

  7. 10. Extraction of Metal Values : Thermodynamics of Electrolyte Solutions and Molten Salts Extraction Process
