    Sammanfattning : ABSTRACTPolyvinyl chloride (PVC) is one of the world’s most widely produced polymers. Its products are used in a wide range of areas such as building and construction, packaging, automotive, electrical/electronic and healthcare. PVC can easily be tailored to adapt material properties to specific applications. LÄS MER

  4. 4. Structural chemistry and optical application

    Detta är en avhandling från Chalmers University of Technology

    Författare :Mohamed Ghazzali; Chalmers tekniska högskola.; Chalmers University of Technology.; Chalmers tekniska högskola.; Chalmers University of Technology.; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Funktionella material; Functional materials; NLO-materials; single crystal x-ray diffraction; porphyrins; conjugated polymers;

    Sammanfattning : The demand for materials with optical activities against LASER radiation has been extensively increased over the last decade with the development of sophisticated high energetic LASER sources. The goal is to obtain organic or metal-organic molecules capable of increasing their absorptions against LASER irradiance while still maintaining a degree of transmittance. LÄS MER

  5. 5. Homochiral crystals for selective synthesis

    Detta är en avhandling från Chalmers University of Technology

    Författare :Theonitsa Kokoli; Göteborgs universitet.; Gothenburg University.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Absolute asymmetric synthesis; total spontaneous resolution; optical activity; coordination compounds; coordination polymers; photoisomerization; enantioselective sulfide oxidation; single crystal X-ray crystallography; co-crystallization of diastereomers;

    Sammanfattning : Six new coordination compounds were prepared from monodentate sulfide ligands and copper(I) halides and their crystal structures were determined by single-crystal X-ray diffraction. The aim was to prepare coordination polymers that crystallize as conglomerates in order to use them in total spontaneous resolution. LÄS MER
