1. 11. Highly enantioselective synthesis of lactam and sugar derivatives by chiral aminocatalysis and merging with transition metal catalysis

   Författare :Zhang Kaiheng; Armando Cordova; Malkov Andrei; Mittuniversitetet; []
   Nyckelord :;

   Sammanfattning : This thesis presented novel methodologies for enantioselectivesynthesis of highly functionalized lactam and sugar derivatives.Asymmetric organocatalysis, cooperative dual catalysis and one-pot multicomponent reaction strategies were applied for the construction of continuous and quaternary stereogenic center.

3. 12. Equilibrium aspects of Cr-alloyed cemented carbides

   Författare :Bartek Kaplan; Malin Selleby; Armando F. Guillermet; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk materialvetenskap; Materials Science and Engineering;

   Sammanfattning : In view of the extensive use of Cr as a grain growth inhibitor in WC-Co cemented carbides this thesis comprises a combined experimental and ab initio study of a number of critical issues pertaining to phase equilibria of the subsystems to the W-Co-Cr-C system.To be able to predict which of the stable Cr-carbides forms above the solubility limits of Cr and C in the fcc phase the respective solubility of Co in Cr23C6, Cr7C3 and Cr3C2 are investigated experimentally.

4. 13. Impact of feedback on the ISM of extreme starburst galaxies : The case of Haro 11

   Författare :Veronica Menacho Menacho; Göran Östlin; Armando Gil de Paz; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Galaxies; stellar feedback; ISM; Integral field spectroscopy; Astronomy; astronomi;

   Sammanfattning : Blue compact galaxies (BCGs) are compact, metal-poor, starbursting galaxies with characteristics similar to what is expected for the young high-redshifted galaxies. BCGs are among the most active in producing a large number of massive star clusters, each containing thousands of massive stars. LÄS MER

5. 14. Aspects of optimizing pulp fibre properties for tissue and packaging materials

   Författare :Hafizur Rahman; Armando Cordova; Per Engstrand; Börje Norlin; Göran Bengtsson; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : To improve the competitive advantages of pulp fibre-based materials for tissue and packaging over fossil-based products, it is essential to increase knowledge of the selectivity of the cooking and the chemimechanical processes by optimizing the unit operations of impregnation, cooking and refining. A general goal in pulping processes is to achieve as efficient and even fibre separation as possible. LÄS MER

7. 15. Organocatalytic Domino Reactions

   Författare :Henrik Sundén; Armando Córdova; Pavel Kočovský; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organocatalytic; domino; iminium-enamine; enamine-iminium; Organic chemistry; Organisk kemi; Organic Chemistry; organisk kemi;

   Sammanfattning : Organocatalyzed reactions involving activation strategies of ketones and aldehydes are important processes in organic chemistry. These activation strategies serve as a versatile platform for the construction of several domino reactions. LÄS MER
