  2. 26. Characterization of Novel Electrolytes for Li-Batteries

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

    Abstract : In a world that strives toward greener and more sustainable energy solutions, the need for suitable energy storage devices has brought Lithium-ion batteries (LIB) into focus of research. Although the Lithium-ion battery is a consolidated technology for portable applications, capacity, cost, and not the least safety aspects are major concerns when it comes to its implementation into large-scale energy storage applications, such as electric vehicles.

  4. 27. The Role of Sugars for Protein Stabilization

    Author : Christoffer Olsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; protein; water; QENS; biomolecule; EPSR; amorphous; trehalose; neutron scattering; cryopreservation; DSC; neutron diffraction; dielectric spectroscopy;

    Abstract : The understanding of biomolecular interactions with water and co-solutes can lead to greater knowledge regarding the mechanisms behind biomolecular stabilization. This is highly important for developing technologies aimed to preserve biological materials. READ MORE

  5. 28. The Quest for M-theory

    Author : Ulf Gran; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; supersymmetry; solitons; gauge symmetry; M-theory; string theory; duality; p-branes; D-branes; superspace; supergravity;

    Abstract : In ten dimensions, there exist five consistent string theories and in eleven dimensions there is a unique supergravity theory. When trying to find the fundamental theory of nature this is clearly an "embarrassment of riches". In the mid 90s, however, it was discovered that these theories are all related via a kind of transformation called duality. READ MORE

  7. 30. Characterisation of Organic Dyes for Solid State Dye-Sensitized Solar Cells

    Author : Ute Cappel; Anders Hagfeldt; Gerrit Boschloo; Udo Bach; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; energy alignment; hole conductor; injection; interface; perylene; photo-induced absorption; regeneration; spectroelectrochemistry; spiro-MeOTAD; Stark effect; titanium dioxide; Physical chemistry; Fysikalisk kemi; Physical Chemistry; Fysikalisk kemi;

    Abstract : Energy from the sun can be converted to low cost electricity using dye-sensitized solar cells (DSCs). Dye molecules adsorbed to the surface of mesoporous TiO2 absorb light and inject electrons into the semiconductor. READ MORE
