  2. 1. Electron Transfer in Ruthenium-Manganese Complexes for Artificial Photosynthesis : Studies in Solution and on Electrode Surfaces

    Author : Malin L. A. Abrahamsson; Gerald J. Meyer; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Artificial photosynthesis; electron transfer; energy transfer; ruthenium; manganese; titanium dioxide; Fysik; Physics; Fysik; Physical Chemistry; fysikalisk kemi;

    Abstract : In today’s society there is an increasing need for energy, an increase which for the most part is supplied by the use of fossil fuels. Fossil fuel resources are limited and their use has harmful effects on the environment, therefore the development of technologies that produce clean energy sources is very appealing. READ MORE

  4. 2. Tuning electron transfer reactions by selective excitation in porphyrin-acceptor assemblies

    Author : Mikael Andersson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; Physical Chemistry; fysikalisk kemi;

    Abstract : This thesis concerns electron transfer reactions from different excited states in porphyrins, and the effect of changing the energy of the link connecting the donor and acceptor. Photoinduced electron transfer, and subsequent processes were studied using ultrashort laser pulses and nanosecond laser flash photolysis. READ MORE

  5. 3. Charge Transport Properties in Nanostructured Electrodes of Metal Oxides

    Author : Niclas Beermann; James Durrant; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Iron oxide; titanium dioxide; nanostructured; photoelectrochemistry; charge transport; morphology; incorporation; Fysik; Physics; Fysik; Physical Chemistry; fysikalisk kemi;

    Abstract : In the last decade research in the field of nanostructured metal oxide thin film electrodes for various applications, e.g., solar cells and hydrogen production, has been of great interest. In this thesis, interfacial and bulk electrochemical properties and charge transport properties of nanostructured thin films have been investigated. READ MORE

  6. 4. Electron and Energy Transfer in Supramolecular Complexes Designed for Artificial Photosynthesis

    Author : Helena Berglund Baudin; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; artificial photosynthesis; electron transfer; energy transfer; ruthenium; manganese; Fysik; Physics; Fysik; Physical Chemistry; fysikalisk kemi;

    Abstract : In the society of today the need for alternative energy sources is increasing. The construction of artificial devices for the conversion of sunlight into electricity or fuel seems very attractive from an environmental point of view, since these devices are based on processes that does not necessarily generate any harmful biproducts.

  7. 5. Liposomes for Drug Delivery : from Physico-chemical Studies to Applications

    Author : Nill Bergstrand; Katarina Edwards; Felix M Goni; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; liposome; steric stabilisation; BNCT; cryo-TEM; EGF; targeting; stability; permeability; pH-sensitive liposomes; triggered release; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

    Abstract : Physico-chemical characterisation of structure and stability of liposomes intended for drug delivery is the central issue in this thesis. In addition, targeted liposomes to be used in boron neutron capture therapy (BNCT) were developed.Lysolipids and fatty acids are products formed upon hydrolysis of PC-lipids. READ MORE
