4. 3. Cryogenic soil processes in a changing climate

   Författare :Marina Becher; Jonatan Klaminder; Johan Olofsson; Jan Karlsson; Niclas Börlin; Philip Wookey; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Non-sorted circle; Carbon storage; Soil motion; Terrestrial photogrammetry; Cryoturbation; Carbon fluxes; naturgeografi; Physical Geography;

   Sammanfattning : A considerable part of the global pool of terrestrial carbon is stored in high latitude soils. In these soils, repeated cycles of freezing and thawing creates soil motion (cryoturbation) that in combination with other cryogenic disturbance processes may play a profound role in controlling the carbon balance of the arctic soil.

5. 4. Oxy-coal combustion and its integration with power systems for CO2 capture

   Författare :Yukun Hu; Jinyue Yan; Roland Span; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxy-coal combustion; flue gas recycle; radiation; peak and off-peak operations; cryogenic CO2 purification;

   Sammanfattning : Oxy-fuel combustion is one of the technologies for carbon dioxide (CO2) capture and storage (CCS) in fossil fuel based power systems to mitigate global greenhouse gases (GHGs) emissions. When introducing oxy-fuel combustion into the power systems, energy penalty for CCS has significant impacts on the system performance. LÄS MER

7. 5. Light’EM up! : structural characterization of light-driven membrane protein complexes by cryogenic electron microscopy

   Författare :André Tomás Graça; Wolfgang P. Schröder; Johannes Messinger; Karina Persson; Werner Kühlbrandt; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 3D reconstruction; Arabidopsis thaliana; assembly; chlorophyll; cryo-EM; cyanobacteria; Deinococus radiodurans; electron; land plants; membrane protein complexes; Photosystem II; proton; single-particle analysis; S-Layer Deinoxanthin Binding Complex SDBC ; water.; Biochemistry; biokemi; biologisk kemi; biological chemistry;

   Sammanfattning : Photosynthesis is probably the most important process for allowing life to develop into the diverse forms we see today. In this process, solar radiation is used to convert CO2 into biomass. From this process, we obtain oxygen to breathe, sources of food (plant biomass), and the potential for clean and sustainable energy. LÄS MER
