  1. 6. SOFC Modeling from Micro- to Macroscale: Transport Processes and Chemical Reactions

    Författare :Hedvig Paradis; Värmeöverföring; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mass transport; diffusion; microscale; porous media; kinetics; LBM; CFD; anode multicomponent; MATLAB;

    Sammanfattning : The purpose of this work is to investigate the interaction between transport processes and chemical reactions, with special emphasis on modeling mass transport by the Lattice Boltzmann method (LBM) at microscale of the anode of a solid oxide fuel cell (SOFC). In order to improve the performance of an SOFC, it is important to determine the microstructural effect embedded within the physical and chemical processes, which usually are modeled macroscopically.

  5. 9. Catalytic Functionalization of Allylic Substrates by Palladium Pincer Complexes

    Författare :Nicklas Selander; Kálmán Szabó; David Milstein; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Catalysis; Palladium; Pincer Complex; Boron; Multicomponent Reaction; Organic chemistry; Organisk kemi; organisk kemi; Organic Chemistry;

    Sammanfattning : This thesis is based on the development of novel catalytic reactions for the synthesis and application of organometallic reagents. The main focus is directed towards organoboronate derivatives. We developed an efficient procedure for converting allylic alcohols to the corresponding allylboronates using palladium pincer complexes as catalysts. LÄS MER
