  2. 16. Exploring new protic ionic liquids: From synthesis to fundamental properties

    Author : Eduardo Maurina Morais; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; thermal analysis; acidity; transport properties; DFT; Protic ionic liquids;

    Abstract : The ionic liquid community frequently leverages the selling point that more than a million new ionic liquids could conceivably be created. Nonetheless, the number of commercially available compounds is orders of magnitude lower. READ MORE

  4. 17. Materials and interfaces for sustainable organic solar cells

    Author : Qilun Zhang; Mats Fahlman; Xianjie Liu; Ronald Österbacka; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Organic Solar Cell; Interfaces; Photoelectron Spectroscopy; Natural based materials; Sustainable;

    Abstract : Photovoltaics, the apparatus utilizing green solar power to generate electricity, is one of the efficient measures to the continuously increasing energy demand and exacerbated carbon emission of the human civilization. As a candidate with the potential of providing the cheapest and greenest form of electricity, organic solar cells (OSCs) received tremendous scientific interest, resulting in a significant power conversion efficiency (PCE) boosting to above 19% recently.

  5. 18. Multifunctional Supramolecular Organic Ferroelectrics

    Author : Indre Urbanaviciute; Martijn Kemerink; Mats Fahlman; Bengt-Harald Jonsson; Van Dijken Sebastiaan; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Ferroelectric materials are known and valued for their multifunctionality arising from the possibility to perturb the remnant ferroelectric polarization by electric field, temperature and/or mechanical stimuli. While inorganic ferroelectrics dominate the current market, their organic counterparts may provide highly desired properties like eco-friendliness, easy processability and flexibility, concomitantly opening unique opportunities to combine multiple functionalities into a single compound that facilitates unprecedented device concepts and designs.

  6. 19. Image dipoles and polarons in organic semiconductors

    Author : Yongzhen Chen; Mats Fahlman; Xianjie Liu; Yiqiang Zhan; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic electronics; Interface dipole; Polaron; Conjugated polymer; Photoelectron spectroscopy; N-type doping; Electron transport material;

    Abstract : The rapid development of organic electronics depends on the synthesis of new π-conjugated molecules/polymers and the exploration of fundamental physics. However, most of the efforts have been concentrated on the former, leading to a lack of thorough understanding of many important concepts, which will become the ultimate limiting factor for overall performance and applications.

  7. 20. Dissolved Organic Matter from a colloidal perspective

    Author : Erika Andersson; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dissolved organic matter; colloids; Microbial decomposition; hematite nanoparticles; soil; small angle scattering; light scattering; 1H NMR;

    Abstract : Dissolved organic matter (DOM) is considered the most bioavailable fraction of soil, and thus play a key role in the cycling of carbon. Because of its mobility, DOM also forms the connection between terrestrial and aquatic systems, and constitutes an important vector for nutrients and contaminants. READ MORE
