1. Environmental Assessment and Strategic Technology Choice : The Case of Renewable Transport Fuels
Sammanfattning : The scale of the required changes is huge, and time is limited if we are to avoid the most severe effects of climate change. To reduce greenhouse gas emissions from road transport, several fuels and electricity originating from renewable energy sources have been proposed, all of them in different stages of development and with various and shifting environmental impacts.

2. Den raka och den krokiga vägen : om genus, ingenjörer och teknikkarriärer
Sammanfattning : Abstract The purpose of this doctoral thesis is to shed light on, explain, and problematize women’s and men’s paths both to and within the profession of engineer. Computer and mechanical engineers are in focus and the overarching issues that this thesis attempts to answer are: How can women’s and men’s paths to the profession of engineer be explained and what has governed/motivated their choice of education? How do women’s and men’s career patterns look in professional life, and how can these patterns be explained? This study is based on a social-constructivistic approach, entailing a focus on how choices of education and profession have been negotiated through social and cultural practices, norms, and values.

3. Silicon Nanoribbon FET Sensors : Fabrication, Surface Modification and Microfluidic Integration
Sammanfattning : Over the past decade, the field of medical diagnostics has seen an incredible amount of research towards the integration of one-dimensional nanostructures such as carbon nanotubes, metallic and semiconducting nanowires and nanoribbons for a variety of bio-applications. Among the mentioned one-dimensional structures, silicon nanoribbon (SiNR) field-effect transistors (FET) as electro-chemical nanosensors hold particular promise for label-free, real-time and sensitive detection of biomolecules using affinity-based detection.

4. Multiscale materials design of hard coatings for improved fracture resistance and thermal stability
Sammanfattning : Physical vapor deposited hard coatings comprised of cubic (c) transition metal (TM)-Al-N, and (TM)-Si-N are the current workhorse materials for a large number of metal cutting and wear resistant applications to fight against the extreme conditions of temperature and stress simultaneously. In spite of a high degree of sophistication in terms of material choice and microstructural design, a lower fracture resistance and limited thermal stability of the coatings remains a technological challenge in the field.

5. Look-ahead Control of Heavy Vehicles
Sammanfattning : Trucks are responsible for the major part of inland freight and so, they are a backbone of the modern economy but they are also a large consumer of energy. In this context, a dominating vehicle is a truck with heavy load on a long trip. LÄS MER
