  2. 16. Plastidial phosphate transport in plants

    Author : Patrik Milton Karlsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis; phosphate transport; thylakoid membrane; root plastid; photosynthesis; leaf size; starch metabolism; homology modeling; site-directed mutagenesis;

    Abstract : Phosphorus is an essential element for all living organisms and is central to the genetics and energetics of life. Inorganic phosphate (Pi) is recurrently involved in protein regulation and signal transduction but also in energy transfer as a component of the ATP-molecule. READ MORE

  4. 17. Iron Based Materials for Positive Electrodes in Li-ion Batteries : Electrode Dynamics, Electronic Changes, Structural Transformations

    Author : Andreas Blidberg; Fredrik Björefors; Torbjörn Gustafsson; Carl Tengstedt; Miran Gaberšček; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Li-ion; batteries; electrochemistry; iron; LiFeSO4F; Li2FeP2O7; PEDOT; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Abstract : Li-ion battery technology is currently the most efficient form of electrochemical energy storage. The commercialization of Li-ion batteries in the early 1990’s revolutionized the portable electronics market, but further improvements are necessary for applications in electric vehicles and load levelling of the electric grid.

    Abstract : The stability of electrode/electrolyte interfaces in Li-ion batteries is crucial to the performance, lifetime and safety of the entire battery system. In this work, interface processes have been studied in LiFePO4/graphite Li-ion battery cells. READ MORE

  6. 19. Nonlinear Optical Materials Structural Studies of Alkali Titanium Phosphates

    Author : Stefan Norberg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nonlinear optical materials; alkali titanium phosphates; phase transition; alkaline cation shifts; rare-earth langbeinites; doped KTP isostructures;

    Abstract : Crystals are beautiful, not only as pieces of jewellery, but also for their intrinsic properties, which are of significant scientific and technological importance. Ferroelectric materials are extremely versatile, since they may be combined with piezoelectric or electrooptic devices for use as filters, oscillators, memories, light detectors, and displays.

  7. 20. Speciation of copper in ashes from municipal solid waste combustion

    Author : Henric Lassesson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; copper compounds; MSWI ash; XANES; metal speciation; EXAFS; X-Ray absorption spectroscopy;

    Abstract : Copper is one of the most important trace elements in municipal solid waste (MSW) combustion. Knowledge of the speciation of copper is fundamental for the understanding of the effects of copper compounds on the combustion chemistry as well as of the environmental impact of the ash. READ MORE
