  1. 1. Enzymes as catalysts in synthesis of enantiomerically pure building blocks : secondary alcohols bearing two vicinal stereocenters

    Författare :Rong Liu; Hans-Erik Högberg; Torbjörn Norin; Thorleif Anthonsen; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; enzyme; kinetic resolution; enantioselectivity; lipase; diastereoselectivity; epimerisation; metal-catalysed transformation; intramolecular alkylation.; Chemistry; Kemi;

    Sammanfattning : Enzymes as tools in organic synthesis have provided enormous advantages. This thesis deals with the applications of enzymes in the kinetic resolutions of racemic compounds. The stereochemistry of chiral compounds and the kinetics of α/β hydrolase lipases are presented. LÄS MER

  2. 2. Life Cycle Assessment of Paper Based Printed Circuits

    Författare :Qiansu Wan; Li-Rong Zheng; Changqing Liu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Printed Electronics; Environment; PCB; Life Cycle assessment; Emissions; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Printed circuit boards have been massively manufactured and wildly used in all kinds of electronic devices during people’s daily life for more than thirty years since the last century. As a highly integrated device mainly consists of silicon base, an etched copper layer and other soldered components, massive production of printed circuit boards are considered to be environmentally unfriendly due to the wet chemical manufacturing mode and lack of recycling ability.
