  1. 1. Time-dependent climate impact of short rotation coppice willow–based systems for electricity and heat production

    Författare :Niclas Ericsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Fossil fuel use and man-made land use change has increased carbon dioxide (CO₂) levels in the atmosphere, contributing to climate impacts such as global warming. Perennial crops such as short rotation coppice (SRC) willow have received attention because of their potential to sequester carbon (C) from the atmosphere and build up soil organic carbon stocks while producing biomass which can be used to generate energy services.

  4. 3. Prospects for Bioenergy in Europe - Supply, Demand and Trade

    Författare :Karin Ericsson; Miljö- och energisystem; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiforskning; Energy research; biofuel trade; perennial energy crops; co-firing; bioenergy policy; biomass production cost; potential biomass supply; Bioenergy; Europe;

    Sammanfattning : Renewable energy sources (RES), such as biomass, can be used to address two important issues in Europe: climate change and energy security. If biomass is produced sustainably and used efficiently, bioenergy contributes very little to CO2 emissions. LÄS MER

  7. 5. The Buried Oxide of Silicon on Insulator Materials

    Författare :Per Ericsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxide defects; internal oxidation; aluminum oxide; wafer bonding; SOI; silicon on insulator; buried oxide;

    Sammanfattning : The buried oxide of silicon on insulator (SOI) wafers plays an important role in the operation of electronic devices made on such materials. The presence of defects in the buried oxide can seriously degrade the performance of a circuit. LÄS MER
