  2. 21. Computational prediction of novel MAB phases

    Author : Adam Carlsson; Johanna Rosén; Denis Music; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The synthesis procedure of any materials system is often considered a challenging task if performed without any prior knowledge. Theoretical models may thus be used as an external input and guide experimental efforts toward novel exotic materials which are most likely to be synthesizable. READ MORE

  4. 22. New Materials for the Molten Carbonate Fuel Cell

    Author : Sara Randström; Carina Lagergren; Michel Cassir; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molten Carbonate Fuel Cell; Anode current collector; Cathode; Wet-seal; Ionic liquid; TFSI; Smältkarbonatbränslecell; Anodströmtilledare; Katod; Wet-seal; Jonvätska; TFSI; Electrochemistry; Elektrokemi;

    Abstract : Smältkarbonatbränslecellen (MCFC) är en högtemperaturbränslecell för stationära applikationer. Den har samma höga totalverkningsgrad som konventionella kraftvärme-anläggningar, men kan byggas i mindre moduler (från 250 kWe). READ MORE

  5. 23. Multistability, Ionic Doping, and Charge Dynamics in Electrosynthesized Polypyrrole, Polymer-Nanoparticle Blend Nonvolatile Memory, and Fixed p-i-n Junction Polymer Light-Emitting Electrochemical Cells

    Author : Daniel Simon; Sue Carter; Frank Bridges; J Campbell Scott; USA Santa Cruz University of California; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; organic electronics; polymer; light emission; biomimetics; memory;

    Abstract : A variety of factors make semiconducting polymers a fascinating alternative for both device development and new areas of fundamental research. Among these are solution processability, low cost, flexibility, and the strong dependence of conduction on the presence of charge compensating ions. READ MORE

  6. 24. Energy Relevant Materials: Investigations Based on First Principles

    Author : Erna-Krisztina Delczeg-Czirjak; Levente Vitos; Manuel Richter; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; magneto-caloric; DFT; elastic constants; Materials science; Teknisk materialvetenskap;

    Abstract : Energy production, storage and efficient usage are all crucial factors for environmentally sound and sustainable future technologies. One important question concerns the refrigeration industry, where the energy efficiency of the presently used technologies is at best 40% of the theoretical Carnot limit. READ MORE

  7. 25. Non-aqueous Electrolytes and Interfacial Chemistry in Lithium-ion Batteries

    Author : Chao Xu; Torbjörn Gustafsson; Kristina Edström; Daniel Brandell; Brett Lucht; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lithium-ion batteries; electrolyte; electrolyte additives; electrochemistry; interfacial chemistry; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Abstract : Lithium-ion battery (LIB) technology is currently the most promising candidate for power sources in applications such as portable electronics and electric vehicles. In today's state-of-the-art LIBs, non-aqueous electrolytes are the most widely used family of electrolytes. READ MORE
