1. 16. Energy and greenhouse gas balance of decentralized energy supply systems based on organic agricultural biomass : a life cycle perspective

   Författare :Marie Kimming; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : More and more farms apply organic production methods to reduce their environmental impact, but currently even organic farms are mainly using fossil fuels. Technologies available today or in the near future make it possible to produce heat, electricity and fuels from agricultural residues or woody biomass. LÄS MER

3. 17. Materials Design for the Improvement of SiC Field Effect Gas Sensor performance in High Temperature Process Control applications

   Författare :Lida Khajavizadeh; Mike Andersson; Fredrik Eriksson; Krisztian Kordas; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Following growing concerns about the effect these last decades of accelerating energy consumption, escalating use of natural (not the least fossil) resources, and waste generation has had on earth’s climate, human health, and the environment, industry is facing mounting pressure to increase the energy-, resource-, and cost-efficiency of both processes and products while drastically reducing pollutant emissions. In response, industry is, besides increasing their utilization of renewable energy and introducing new bio-based products, taking advantage of the rapid development in 5G technology and associated wireless interconnectivity to move towards full automation of production processes and facilities.

4. 18. Towards Understanding the Pelletizing Process of Biomass : Perspectives on Energy Efficiency and Pelletability of Pure Substances

   Författare :Stefan Frodeson; Jonas Berghel; Sylvia Larsson; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pelletability; wood pellets; densification; chemical composition; Miljö- och energisystem; Environmental and Energy Systems;

   Sammanfattning : The use of fossil resources has to decrease and the use of renewable resources has to increase significantly to mitigate the climate change. In this change towards more renewable resources, biomasses will play an important role, both for energy use and for products. LÄS MER

5. 19. Exergy Analysis in Buildings : A complementary approach to energy analysis

   Författare :Marco Molinari; Folke Björk; Gudni Jóhannesson; Ivo Martinac; KTH; []
   Nyckelord :Exergy; Energy; Building systems performance; Built environment.;

   Sammanfattning : Though mandatory to be pursued, improved energy efficiency is not the only target to reach. The quality of energy has to be assessed as well. Most of the overall energy use in residential building is for low temperature heat, i.e. LÄS MER

7. 20. Genome editing of oilseed species by CRISPR/Cas9 for trait improvement

   Författare :Sjur Sandgrind; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : The demand for vegetable oils for food and other applications is rapidly increasing due to a growing population and an urgent need to replace fossil oils. Furthermore, there are several challenges facing agricultural production, such as a shortage of arable land, climate change, and water pollution due to nutrient leaching from extensive use of fertilizers and tillage.
