    Author : Elisabet Horvath; KTH; []
    Keywords : adsorption; electrolyte; polyelectrolyte; ;

    Abstract : The polyelectrolyte titration method has been developed overthe years in order to determine the surface charge ofcellulosic fibers. The conditions have been varied depending onthe author. READ MORE

  5. 3. Molecular structure, interactions, and dynamics of novel Li-battery electrolytes

    Author : Luis Aguilera Medina; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; SAXS; Raman scattering; imidazolium; NSE; lithium ion battery; electrolyte; organic solvent; pyrrolidinium; TFSI; ionic liquid;

    Abstract : Lithium-ion batteries are one of the most promising candidates for energy storage in sustainable technologies such as electro-mobility or renewable energy systems. However, at present they are incapable to compete with the combustion engine to power vehicles in terms of capacity, price, and safety. READ MORE

  6. 4. Clinical studies in severe heart failure : neurohormonal, electrolyte and metabolic aspects

    Author : Mats Broqvist; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Congestive heart failure is a common and complex syndrome with a poor prognosis. Although heart disease is usually the primary event, the clinical syndrome is characterised by several extra-cardiac manifestations. Neurohormonal activation seems to play a crucial role for these manifestations and the progression of the disease. READ MORE

  7. 5. Modelling of Battery Electrolyte Interactions

    Author : Gustav Åvall; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lithium-ion batteries; semi-empirical Methods.; sodium-ion batteries; ab initio molecular dynamics; electrolytes; density functional theory;

    Abstract : The rechargeable lithium-ion battery (LIB), powering our portable electronics, has transformed our everyday lives. Even though the success of the LIB there is a need for next generation batteries, due to a lack of abundant lithium and a need for greater performance and sustainable chemistries, in order to move towards a sustainable society with applications such as hybrid and electrical vehicles (EVs) and large scale energy storage for solar and wind power.
