  1. 1. Development of Multi-Component Reactions using Catalytically Generated Allyl Metal Reagents

    Författare :Nicklas Selander; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic Chemistry; Organic chemistry; Organisk kemi;

    Sammanfattning : This licentiate thesis is based on the development of catalytic reactions for the synthesis and application of organometallic reagents. By use of palladium pincer-complex catalysts, we have developed an efficient procedure for the synthesis of allylboronates starting from allylic alcohols. LÄS MER

  3. 2. Numerical simulation of multi-scale transport processes and reactions in pem fuel cells using two-phase models

    Författare :Munir Khan; Jinliang Yuan; Bengt Sundén; Värmeöverföring; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; numerical analysis; multi-scale; multi-phase; reacting flows; multi-component;

    Sammanfattning : A numerical study for the cathode of a PEM fuel cell has been performed in this study. The results have been limited to cathode only because, in PEM fuel cells, the oxygen reduction reactions, ORRs, are considered the rate limiting reactions and govern the fuel cell performance.

  4. 3. Development of 2-Pyridone-based central fragments : Affecting the aggregation of amyloid proteins

    Författare :Magnus Sellstedt; Fredrik Almqvist; Petri Pihko; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 2-pyridone; central fragment alteration; multi-component reactions; directed diversity-oriented synthesis; peptidomimetics; amyloid; protein aggregation; pilicide; curlicide; Biorganic Chemistry; bioorganisk kemi;

    Sammanfattning : There are many applications of small organic compounds, e.g. as drugs or as tools to study biological systems. Once a compound with interesting biological activity has been found, medicinal chemists typically synthesize small libraries of compounds with systematic differences to the initial “hit” compound.

  5. 4. Organocatalytic Transformations with N-Heterocyclic Carbenes - An Investigation of Ionic Liquids as NHC Precatalysts and Aerobic Oxidative Esterifications

    Författare :Linda Ta; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; N-heterocyclic carbene; ionic liquid; multi-component reaction; aerobic oxidation; OTHO; Organocatalysis; green chemistry;

    Sammanfattning : The call for more sustainable processes in the chemical society has led to the development of the field of green chemistry. The Twelve Principles of Green Chemistry serve as guidelines for the design of processes. LÄS MER

  7. 5. Investigations of Slag Properties and Reactions

    Författare :Mikael Persson; Seshadri Seetharaman; Masanori Iwase; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik;

    Sammanfattning : The present dissertation describes the efforts directed towards the development of computational tools to support process modeling. This work is also a further development of the Thermoslag® software developed in the Division of Materials Process Science, KTH. LÄS MER
