21. 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.

22. Compact Soft X-Ray Microscopy : Sources, Optics and Instrumentation
Sammanfattning : This thesis describes the development of a sub-60-nm full-period resolution compact soft x-ray microscope operating in the water-window region (2.3-4.4 nm). Soft x-ray water-window microscopy is a powerful technique for high-resolution imaging of organic materials exploiting the natural contrast mechanism between carbon and oxygen, cf. LÄS MER
23. Compact Soft X-Ray Microscopy
Sammanfattning : This thesis describes the development of soft x-rayreflective optics, instrumentation and applications for compactsoft x-ray microscopy. The microscope is based on a table-topliquid-jet-target laser-plasma source in combination with aspherical normal-incidence multilayer condenser mirror andnanofabricated diffractive optics for imaging.

24. Dermal cell trafficking : from microscopy to microdialysis
Sammanfattning : The term dermal cell trafficking has been used to describe the dynamic nature of cell movement in the dermis reflecting the skin's role as an immunological organ. A light microscopic experimental model for qualitative and quantitative counting of the dermal inflammatory cell infiltrate in allergic, acute irritant and cumulative irritant contact reactions has been developed In human studies use of microdialysis technique has enabled observation of biochemical events in the skin, in vivo over a period of time.

25. Characterizing cavity containing materials using electron microscopy : A study of metal oxides, mesoporous crystals and porous material containing nanosized metal-particles
Sammanfattning : This thesis concerns the characterization of novel materials by utilizing electron microscopy techniques. The examined materials contain cavities with certain attributes that enables desired properties for applications such as gas separation, catalysis and fuel cells. LÄS MER
