6. Interactions between whole blood and TiO₂ surfaces with focus on adhesion and activation of PMN granulocytes
Sammanfattning : Foreign materials come in contact with the human body more and more frequently. The surgical procedure of inserting an implant into the body will cause bleeding, evoke an inflammatory response and initiate a healing process, ultimately leading to acceptance or rejection of the material.

7. Raman Spectroscopy and Hyperspectral Analysis of Living Cells Exposed to Nanoparticles
Sammanfattning : Nanoparticles, i.e. particles with at least one dimension smaller than 100 nm, are present in large quantities in ambient air and can also be found in an increasing amount of consumer products. It is known that many nanomaterials have physicochemical properties that differ from physicochemical properties of the same material in bulk size. LÄS MER
8. Methods for evaluation of early bone healing at titanium implants
Sammanfattning : Titanium has for a long time been the implant material of choice when in need for abilities as strength, biocompatibility and stability. Although numbers of studies have been made, little is known about the early events in implant healing. The primary aim in this thesis was to develop methods for evaluating bone healing around implants. LÄS MER
9. Porcelain veneering of titanium : clinical and technical aspects
Sammanfattning : Guld- och andra legeringar har i många år använts som material vid framställning av kronor och broar för ersättning av skadade eller förlorade tänder. Emellertid har tvivel uppstått kring lämpligheten av att använda guldlegeringar i tandersättningar, då guld har visat sig kunna ge biverkningar i form av allergiska reaktioner. LÄS MER
10. Complex Oxide Photonic Crystals
Sammanfattning : Microphotonics has been offering a body of ideas to prospective applicationsin optics. Among those, the concept of photonic integrated circuits (PIC’s) has recently spurred a substantial excitement into the scientific community. Relisation of the PIC’s becomes feasible as the size shrinkage of the optical elements is accomplished. LÄS MER
