Sammanfattning : How could one understand and interpret the phenomenon of information technology, is the overall research question of this licentiate dissertation. The point of departure is the way some official texts in Sweden define the concept of information technology. It is possible to identify two dominating discourses; the technical and the social.

Sammanfattning : In this thesis, conventional and unconventional technologies have been studied and combined in order to make heterogeneous microfluidics with potential advantages, especially in biological applications. Many conventional materials, like silicon, glass, thermoplastic polymers, polyimide and polydimethylsiloxane (PDMS) have been combined in building heterogeneous microfluidic devices or demonstrators.

Sammanfattning : The GaAs-based vertical-cavity surface-emitting laser (VCSEL) is the standard light source in today's optical interconnects, due to its energy efficiency, low cost, and high speed already at low drive currents. The latest commercial VCSELs operate at data rates of up to 28 Gb/s, but it is expected that higher speeds will be required in the near future. LÄS MER
Sammanfattning : Alloys have for a long time been important in the development of our society; from the bronze age, where man learned how to alloy copper with tin, to today, where many products are made of steel and aluminum alloys. Similarly, but maybe not as generally well known, also in heterogeneous catalysis alloys are explored to develop solutions to increase activity and selectivity of chemical processes. LÄS MER
Sammanfattning : Nanoparticles are, due to their large exposed surface area, widely used in the field of heterogeneous catalysis where they accelerate and steer chemical reactions. Although catalysis has been known about for centuries, the scrutiny of catalysts under realistic application conditions is still a major challenge. LÄS MER
