1. 1. Conducting Polymers Containing In-Chain Metal Centres : Electropolymerisation and Charge Transport

   Författare :Johan Hjelm; Anders Hagfeldt; Emad Mukhtar; Robert Forster; A. R. Hillman; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Polymer electrochemistry; Conducting Polymers; Metal Complexes; Electropolymerization; Electron-hopping; Microelectrodes; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

   Sammanfattning : Conjugated polymers that exhibit high electronic conductivities play key roles in the emerging field of molecular electronics. In particular, linking metal centres with useful electrochemical, photophysical, or catalytic properties to the backbone, or within the polymer chain itself, is a topic which has attracted a significant amount of interest lately.

3. 2. NADH:quinone oxidoreductase: the black box of the respiratory chain

   Författare :Robert Roth; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NADH:quinone oxidoreductase; Complex I; electron transport; membrane protein; ubiquinone; respiratory chain; respiration; metabolism; Metabolism; Biokemi; Biochemistry;

   Sammanfattning : Complex I or NADH:quinone oxidoreductase the largest, most complex and least understood of the five membrane-bound enzyme complexes constituting the mitochondrial respiratory chain. The enzyme is present in all types of organisms, from bacteria to mammals. LÄS MER

4. 3. Electron transport in π-conjugated systems

   Författare :Magnus Paulsson; Libero Zuppiroli; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : This thesis deals with theoretical studies of electron localization and conductance in conjugated molecular systems. Anderson localization of electrons is examined for nearly one-dimensional systems. This work was performed to understand the peculiar electronic properties of conducting polymers. LÄS MER

5. 4. Prokaryotic respiratory supercomplexes : Studies of interactions between complexes III and IV

   Författare :Olga Stah; Pia Ädelroth; Petra Hellwig; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; bioenergetics; membrane protein; bacterial respiration; electron transport chain; supercomplex; cytochrome c oxidase; membrane-anchored cytochrome c; cytochrome bc1 complex; electron transfer; proton transfer; time-resolved spectroscopy; apoptosis; biokemi; Biochemistry;

   Sammanfattning : Respiratory processes for cellular energy conversion are carried out by the membrane-associated enzymes of the electron transfer chain (ETC). In recent years there has been emerging data showing that the members of the ETC organize into higher-level assemblies called supercomplexes (SCs) whose functional relevance is not yet fully understood.

7. 5. On the antiporter-like subunits of respiratory chain Complex I - implications for the evolution and coupling mechanism of the NADH:quinone oxidoreductase enzyme complex

   Författare :Cecilie Mathiesen; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metabolism; Biokemi; metabolism; Biochemistry; mrp; electron transport; respiration; membrane protein;

   Sammanfattning : Complex I or NADH:quinone oxidoreductase is the largest enzyme complex, but the least understood energy coupling site in the respiratory chain of mitochondria and bacteria. No high-resolution structural information exists for this enzyme and the molecular mechanism that couples electron transfer and proton pumping is not understood. LÄS MER
