    Author : Xiao Huang; Adolf Gogoll; Martin Sjödin; Maria Strømme; David Mecerreyes; Berit Olofsson; Fredrik Björefors; Tom Lindfors; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Organic electrode material; Energy storage; Conducting redox polymer; Polythiophene; Terephthalate; PEDOT; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Abstract : Organic electrode materials represent an intriguing alternative to their inorganic counterparts due to their sustainable and environmental-friendly properties. Their plastic character allows for the realization of light-weight, versatile and disposable devices for energy storage. READ MORE

  2. 2. The Bentonite Barrier - Swelling Properties, Redox Chemistry and Mineral Evolution

    Author : Daniel Svensson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; montmorillonite; bentonite; smectite; freezing; thawing; hydration; intercalation; four-water-layer; ethylene glycol; X-ray diffraction; time-resolved; spatial-resolution; XANES; Fe; redox; iron; ABM; TBT; Äspö;

    Abstract : Bentonite is planned for use as a buffer material in high-level radioactive waste repositories, where safety assessment is performed for very long periods (100-1000 ka). This thesis focuses on the swelling of smectites in liquid water, and analysis of bentonite from field experiments at Äspö Hard Rock Laboratory, Sweden. READ MORE

  3. 3. Dinuclear Manganese Complexes for Artificial Photosynthesis : Synthesis and Properties

    Author : Magnus Anderlund; Björn Åkermark; William H. Armstrong; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Crystal Structure; Artificial photosynthesis; Manganese complex; Organic chemistry; Organisk kemi;

    Abstract : This thesis deals with the synthesis and characterisation of a series of dinuclear manganese complexes. Their ability to donate electrons to photo-generated ruthenium(III) has been investigated in flash photolysis experiments followed by EPR-spectroscopy. READ MORE

  4. 4. Environmental levels of thallium : influence of redox properties and anthropogenic sources

    Author : Ulrika Karlsson; Stefan Karlsson; Anders Düker; Roger Herbert; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; thallium; Tl I ; Tl III ; separation; ion chromatography; fresh water; sediment; mine waste; fly ash; redistribution; ICP-MS; Environmental chemistry; Miljökemi; Kemi; Chemistry;

    Abstract : Thallium is a highly toxic element that humans are exposed to mainly by consumption of drinking water and vegetables grown in soil with high thallium content but also through inhalation of particles in the air. Thallium is also present in fossil fuels, alloys, and in electronic utilities. READ MORE

  5. 5. Electrochemical Studies of Redox Properties and Diffusion in Self-Assembled Systems

    Author : Johan Kostela; Mats Almgren; Maja Elmgren; Martin Malmsten; Renata Bilewicz; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; electrochemistry; self-assembly; bicontinuos cubic phase; redox potential; diffusion; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi;

    Abstract : In this thesis electron transfer reactions and diffusion of redox molecules in three different types of self-aggregated structures are investigated. Electrochemistry was used to investigate the redox potential and diffusion coefficients for redox active molecules with different polarity. The first aggregate system studied was the micellar phase.
