    Sammanfattning : According to the famous axiom known as Moore’s Law the number of transistors that can be etched on a given piece of ultra-pure silicon, and therefore the computing power, will double every 18 to 24 months. However, around 2020 hardware manufacturers will have reached the physical limits of silicon. LÄS MER

  5. 14. Synthesis and Evaluation of Photoactive Pyridine Complexes for Electron Transfer Studies and Photoelectrochemical Applications

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Fullerene; solar cell; bipyridines; Ruthenium; organic synthesis; Organisk kemi; Organic chemistry; Organisk kemi;

    Sammanfattning : In this thesis, the preparation of new photoactive substances containing mono- and bipyridines coordinated to ruthenium is presented together with initial evaluations of their photoelectrochemical and photophysical properties. Complexes of the type Ru(bpy)2(4-X-py)2 (X = SH, COOH) were prepared and used in Grätzel-type solar cells based on ZnO. LÄS MER
