   Sammanfattning : The current societal needs for fuels and chemical commodities strongly depend on fossil resources. This dependence can lead to economic instabilities, political problems and insecurity of supplies. LÄS MER

4. 13. Spatial forest resource competition: an economic study : How increased competition and production flexibility affect woody feedstock markets

   Författare :Elias Olofsson; Robert Lundmark; Hanne Kathrine Sjölie; Luleå tekniska universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi;

   Sammanfattning : This thesis explores the Swedish forestry and forest industry sectors, together with their adjoining markets, and examines how these sectors are currently positioned to meet future developments and demands. For this purpose, four specific research questions are formulated, focusing on: (1) the structural composition of forest industry sector and how it will be affected by an increasing feedstock competition; (2) the production flexibility of the forest industry; (3) the resource allocation and price effects from increased feedstock competition; and (4) the potential implications from improved harvesting efficiency.

5. 14. Wise Process Routes for Varying Feedstock in Base Metal Extraction : Modelling of a Peirce-Smith Converter and Investigation of Buildup Formation in an Electric Smelting Furnace

   Författare :Andreas Lennartsson; Pekka Taskinen; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

   Sammanfattning : Copper, like silver and gold, is one of the metals that are known to have been worked by some of the oldest civilisations on record. It is used forits unique properties such as corrosion resistance, good workability, high thermal conductivity and attractive appearance. LÄS MER

7. 15. Towards Controlled Growth and Applications of Carbon Nanotubes

   Författare :Raluca Elena Morjan; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; acetylene; carbon nanotubes; carbon feedstock; chemical vapor deposition; fullerenes; dc-glow discharge plasma; growth mechanism; metal catalyst;

   Sammanfattning : This thesis deals with growth, characterization and application of carbon nanotubes. The methods involved in the production of carbon nanotubes are thermal chemical vapor deposition (T-CVD) and plasma enhanced chemical vapor deposition (PE-CVD). LÄS MER
