21. Surface interactions of wood with adhesives and coatings
Sammanfattning : The theme of this thesis is the properties of wood surfaces,and particularly some important aspects of their interactionswith adhesives and coatings.The surface inactivation of wood due to the development ofchemical weak boundary layers was monitored by wettabilitystudies based on contact angle measurements.

22. The making and breaking of families : Studies on inequalities in the face of parenthood and separation
Sammanfattning : Becoming a parent for the first time is one of the most life-altering events individuals experience. For some, this life-altering change is also followed by the breaking of families when couples part ways in either divorce or separation. LÄS MER
23. Silicon Nanopore Arrays : Fabrication and Applications for DNA Sensing
Sammanfattning : Nanopore biomolecule sensing and sequencing has emerged as a simple but powerful tool for single molecule studies over the past two decades. By elec- trophoretically driving single molecules through a nanometer-sized pore, often sitting in an insulating membrane that separates two buffer solutions, ionic current blockades can be detected to reveal rich information of the molecules, such as DNA length, protein size and conformation, even nucleic acid se- quence.

24. Low-Power Nanowire Circuits and Transistors
Sammanfattning : This thesis explores several novel material systems and innovative device concepts enabled by nanowire technology. State-of-the-art fabrication techniques such as electron beam lithography and atomic layer deposition are utilized to achieve high control and quality in the device fabrication. LÄS MER
25. Exploring the Possibilities of 14C Bomb-Pulse Dating of Human Tissue Samples
Sammanfattning : The testing of nuclear weapons in the atmosphere, in the middle of the 20'h century, resulted in a bomb-pulse excess of atmospheric 14C. A bomb-pulse dating method was thus developed. The latter is a method to determine the time of formation of formerly living modern (i.e. LÄS MER
