11. Quantitative microscopy of coating uniformity
Sammanfattning : Print quality demands for coated papers are steadily growing, and achieving coating uniformity is crucial for high image sharpness, colour fidelity, and print uniformity. Coating uniformity may be divided into two scales: coating thickness uniformity and coating microstructure uniformity, the latter of which includes pigment, pore and binder distributions within the coating layer.

12. Mechanical behaviour of carbon nanostructures
Sammanfattning : AbstractCarbon nanotubes (CNTs) have extraordinary mechanical and electrical properties. Together with their small dimensions and low density, they are attractive candidates for building blocks in future nanoelectromechanical systems and for many other applications. LÄS MER
13. Quantitative Electron Microscopy Studies of Metal Nanoparticle Catalysts: Nanostructure, Support Interaction and Ageing Effects
Sammanfattning : Heterogeneous catalysis plays a major role in modern society, for example in chemical production, sustainable energy production and emission control technologies. Metal nanoparticles (NPs) supported on oxide materials are frequent catalytic systems in this field. LÄS MER
14. Scanning Tunnelling Microscopy and Spectroscopy of Adsorbates on Aluminium and Silicon
Sammanfattning : The main topic of this thesis is the investigation of atomic andmolecular adsorbates on single crystal surfaces of silicon and aluminiumusing the techniques of scanning tunnelling microscopy (STM) andspectroscopy (STS). The emphasis has been to use atomic-resolutionspectroscopy and imaging to determine the relationship between thesurfaces' geometric and electronic structures. LÄS MER
15. Development of Techniques for Characterization, Detection and Protein Profiling of Extracellular Vesicles
Sammanfattning : Nanosized extracellular vesicles (EVs, ∼30-2000 nm) have emerged as important mediators of intercellular communication, offering opportunities for both diagnostics and therapeutics. In particular, small EVs generated from the endolysosomal pathway (∼30-150 nm), referred to as exosomes, have attracted interest as a suitable biomarker for cancer diagnostics and treatment monitoring based on minimally invasive liquid biopsies.
