   Sammanfattning : The concept of open innovation has received increased attention among practitioners as well as in academia in recent years. It provides a conceptual platform for understanding how external sources of knowledge drive internal growth. LÄS MER

4. 3. Steam Explosion of Wood

   Författare :Muhammad Muzamal; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element model; Steam explosion; biorefinery; pretreatment; wood;

   Sammanfattning : The rising price of petroleum and environmental concerns regarding CO2 emissions has increased interest in alternative renewable resources. Biomass can be considered as an excellent alternative raw material. A biorefinery uses biomass and produces fuel, energy and value-added chemicals. LÄS MER

5. 4. Hybrid Solvents based on Ionic Liquids/Deep Eutectic Solvents for CO2 Separation : Experiments, Modeling, Process Simulation and Evaluation

   Författare :Chunyan Ma; Xiaoyan Ji; Päivi Mäki-Arvela; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 separation; Ionic liquids; Deep eutectic solvents; Cosolvent; Thermodynamic modeling; Process simulation and evaluation; Energiteknik; Energy Engineering;

   Sammanfattning : CO2 separation plays a vital role in reducing CO2 emissions to combat climate change, in which solvent-based absorption is widely considered the most promising technology. Many conventional chemical and physical solvents have been introduced for CO2 separation, still facing challenges. LÄS MER

7. 5. Initiating Original Equipment Manufacturer Remanufacturing

   Författare :Johan Vogt Duberg; Erik Sundin; Jelena Kurilova-Palisaitiene; Ou Tang; Patricia van Loon; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Remanufacturing; Circular economy; Value-retention process; Economic assessment; Initiation; Prerequisite.; Återtillverkning; Cirkulär ekonomi; Värdebevarande process; Ekonomisk värdering; Initiering; Förutsättning.;

   Sammanfattning : Remanufacturing is an industrial process in which a core – a used, discarded, or broken product – is transformed into a product whose specification and condition are new-like. However, to this date, remanufacturing activities on the market are few in comparison to manufacturing. LÄS MER
