11. Synthesis and Characterization of Transition Metal Diborides
Sammanfattning : This thesis is devoted towards physical vapor deposition (PVD) of thin films of transition-metal (TM) diborides, focused on the material system TiBx, Ti1-xAlxB2-y and CrBx. The metal diborides are a large family of compounds with both metallic and ceramic properties, due to its bonding nature being a mix of covalent and ionic bonds. LÄS MER
12. The Baltic Sea from the present to future : microbial carbon & nutrient cycling in a changing climate
Sammanfattning : Climate Change is caused by the accelerated increase of anthropogenic greenhousegas emissions to the atmosphere and affects all ecosystems on our planet. A resultof higher CO2 uptake by the oceans as well as an increase of heat trapped in theatmosphere leads to, for example acidification, stratification, sea-level rise, oxygenloss, and temperature increase of the earth’s waterbodies.

13. Silicon photonic MEMS building blocks for low-power programmable circuits
Sammanfattning : Silicon photonics, or the confinement and control of light in integrated silicon waveguides, has rapidly grown from research labs to high-end chips for telecommunications. With the associated improvements in waveguide performance, the technology is promising for a wide range of new applications, from computing to sensing. LÄS MER
14. Design for 3D Concrete Printing : Optimisation Through Integrated Workflows
Sammanfattning : The transition from conventional cast concrete to 3D Concrete Printing (3DCP) marks a paradigm shift by directly depositing fresh concrete layer upon layer according to a digital model without the need for a formwork. This technology offers the possibility of achieving innovative and complex geometries in an automated process. LÄS MER
15. InAs Nanowire Devices and Circuits
Sammanfattning : Since the introduction of the transistor and the integrated circuit, the semiconductor industry has developed at a remarkable pace. By continuously fabricating smaller and faster transistors, it has been possible to maintain an exponential increase in performance, a phenomenon famously described by Moore’s Law. LÄS MER
