    • The study presents findings regarding drivers' patterns of use, attitude towards, and reported effects of access tomature nomadic navigation support systems. Three different systems were tested by 582 drivers in four-field operationaltests for a period of six months. A majority of the participants used the support system for trips where the route/destination was unfamiliar but there were also other use scenarios. The main benefits entailed convenience andcomfort. Reported effects involved increased possibilities to choose the route according to preferences; a decrease inthe time it took to reach destinations and in the distance covered to reach the destination. One in four reported adecrease in fuel consumption attributed an increased compliance with speed limits and/or that driving around andsearching for the correct route to reach the desired destination could be avoided. A majority reported ‘no change’regarding the number of journeys made by car. Reported effects (whether increases or decreases) were howeversmaller than expected before the trial.

  • Short-range structure of proton-conducting perovskite BaInxZr1-xO3-x/2 (x=0-0
  • 2009
  • Ingår i: Chemistry of Materials. - : American Chemical Society (ACS). - 0897-4756 .- 1520-5002. ; 20:10, s. 3480-3486
  • Tidskriftsartikel (refereegranskat)abstract
    • In a systematic study, we investigate the effect of dopant level and hydration on the short-range structure of the proton-conducting perovskite-type oxide BaInxZr1-xO3-x/2 (x = 0 - 0.75), using infrared and Raman spectroscopy. The results show that the doping leads to significant local distortions of the average cubic structure of these materials. By increasing the In concentration from x = 0 to x = 0.75, new bands appear and grow in intensity in both the IR and the Raman spectra, showing that the local distortions become successively more and more pronounced. The structural distortions are largely uncorrelated to the presence of oxygen vacancies, but instead are mainly driven by the size and charge difference between the In3+ and Zr4+ ions, which leads to displacements of the cations and to tilting of the (In/Zr)O-6 octahedra. On the basis of our results, we suggest that there is a threshold between x = 0.10 and x = 0.25 where the structural distortions propagate throughout the whole perovskite structure. Comparison of our spectroscopic data with the proton conductivity for the same materials indicates that the presence of extended structural distortions is favorable for fast proton transport.

  • Solid state proton conductors: hydrated perovskites and hydrated alkali thio-hydroxogermanates
  • 2007
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • This thesis concerns experimental studies of hydrated perovskites and hydrated alkali thio-hydroxogermanates, two classes of solid state proton conductors which are promising to be used as electrolytes in future intermediate temperature (200-500°C) fuel cells.This is an attractive temperature range for many applications but for which today's available electrolytes do not show satisfactory performance. For the development of new materials with better performances a deeper understanding of the structure and proton dynamics of the material is essential.Incorporation of protons in perovskites, A2+B4+O2-3, requires the formation of oxygen deficient structures through acceptor doping, AMxB1-xO3-d (M = Y3+, Yb3+, In3+, Ga3+ etc.), and subsequent hydration.Key issues to understand are how the type and concentration of dopant atoms and the presence of oxygen vacancies influence the structure and proton dynamics of the material. These issues have been addressed in this thesis, in particular for the proton conducting BaInxZr1-xO3-x/2 (0.10
