  1. 1. Experimental investigation of premixed ammonia combustion at high Karlovitz number conditions

    Författare :Qingshuang Fan; Förbränningsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulent premixed combustion; Ammonia flames; Laser diagnostics; Flame structure; High Karlovitz number; Turbulent burning velocity; Fysicumarkivet A:2021:Fan;

    Sammanfattning : This thesis aims to acquire deep knowledge on turbulent premixed combustion at high Karlovitz (Ka) number conditions with the help of laser-based diagnostic measurements.Considering that ammonia (NH3), as a carbon-free energy carrier, is a promising candidate for replacing conventional fossil fuels in the future, all the investigations in this work were carried out on ammonia/air premixed flames.

  4. 3. Towards Artificial Photosynthesis: Exploration of Efficient First-Row Transition Metal-Based Water Oxidation Catalysts

    Författare :Lizhou Fan; Licheng Sun; Thomas Wågberg; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Artificial photosynthesis; Water oxidation; Heterogeneous catalyst; Electrochemistry; Electronic structure; Kemi; Chemistry;

    Sammanfattning : Artificial photosynthesis provides a promising strategy for sustainable energy harvesting, yet its overall efficiency is limited by the water oxidation reaction. The subject of this thesis focuses on the exploration of highly efficient cost-effective heterogeneous catalysts for water oxidation, and the investigation of essential catalyst structure-activity relationships.

  5. 4. Viral Strategies to Regulate Transcription and Pre-mRNA Splicing

    Författare :Shaoan Fan; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Adenovirus E1B-55kDa; E4-ORF4; E4-ORF6 proteins; L1 mRNA; Polyoma virus small T antigen; regulation; transcription; splicing; PP2A; Biokemi; Biochemistry; Biokemi; Medical Virology; medicinsk virologi;

    Sammanfattning : A typical DNA virus encodes for a few key regulatory proteins that modify the host cell biosynthetic machinery to achieve a selective viral gene statement. One such example is illustrated by the adenovirus E4-ORF4 protein, which form an enzymatically active complex with the serine and threonine-specific protein phosphatase 2A (PP2A). LÄS MER

  7. 5. Mechanistic Modeling of Annular Flows at Near-Dryout Conditions

    Författare :Wenyuan Fan; Henryk Anglart; Martin Rohde; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kärnenergiteknik; Nuclear Engineering;

    Sammanfattning : This work aims at advancing the modeling methodology for near-dryout annular flows using two different computational fluid dynamics (CFD) approaches. One is termed as the transported film approach, where the film flow is separately modeled by a simplified liquid film model and then coupled with the gas core simulation using various closures.
