1. 1. Latent Heat Thermal Energy Storage for Indoor Comfort Control

   Författare :NingWei Justin Chiu; Viktoria Martin; Motoi Yamaha; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Energy Storage; Phase Change Material; Indoor Comfort; Heat Transfer; Termisk Energilagring; Fasändringsmaterial; Inomhuskomfort; Värmeöverföring;

   Sammanfattning : Equating Earth’s existence to 24 hours, we, the Homo sapiens, came about in the last four seconds. Fossil fuel came to our knowledge with mass extraction dating from the Industrial Revolution two centuries ago, in other words 4 milliseconds out of Earth’s 24-hour equivalent lifetime. LÄS MER

3. 2. Partial carbon capture – an opportunity to decarbonize primary steelmaking

   Författare :Max Biermann; Chalmers tekniska högskola; []

   Sammanfattning : Climate change requires that all energy-related sectors drastically reduce their greenhouse gas emissions (GHG). To have a high likelihood of limiting global warming to 1.5°C, large-scale mitigation of GHG has to start being implemented and cause emissions to fall well before Year 2030. LÄS MER

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

   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

5. 4. Extension of PC-SAFT to model inhomogeneous and transport properties

   Författare :Gulou Shen; Georgios Kontogeorgis; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

   Sammanfattning : CO2 separation plays an important role in greenhouse gas emission mitigation, in bio-fuel production via biomass gasification as well as in biogas upgrading. The current CO2 separation technologies are energy intensive, and new cost-effective CO2 separation technologies are needed. LÄS MER

7. 5. Free Energy and Surface Forces in polymer systems: Monte Carlo Simulation Studies

   Författare :Andrei Broukhno; Beräkningskemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polyelectrolytes; electrostatic interactions; phase transitions; colloidal stability; surface forces; Monte Carlo simulation; free energy evaluation; polyampholytes; Physical chemistry; Fysikalisk kemi;

   Sammanfattning : The thesis is focused on two major subjects: - Calculation of free energy is of great help in the study of any molecular system. The free energy determines phase behaviour of colloids and polymer solutions. It also controls the conformational properties of single macromolecules, e.g. LÄS MER
