  2. 1. Molecular Solar Thermal Energy Storage System: Evaluation of Different Candidates

    Author : Zhihang Wang; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy storage and release; Vinylheptafulvene; Catalyst; Quadricyclane; Solar Energy; Thermal dynamics; Molecular switches; Azobenzene; Norbornadiene; Energy conversion; Dihydroazulene;

    Abstract : The development of solar energy can potentially meet the growing requirements for a global energy system beyond fossil fuels, however necessitates new scalable technologies for solar energy storage. One approach is the development of energy storage systems based on molecular photoswitches, so-called molecular solar thermal energy storage (MOST). READ MORE

  4. 2. All-Photonic Control of Biorelevant Processes using Molecular Photoswitches and Caged Compounds

    Abstract : The development of light-controlled molecular tools for in situ regulation of biological activity holds great promise e.g. for resolving dynamic aspects of cellular signal transduction and to overcome inherent pharmaceutic limitations such as poor drug selectivity. READ MORE

  5. 3. Thermal Isomerization of Azobenzene Side Chain Copolymers

    Author : Viktoria Skeppstedt; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; free volume; thermal isomerization; positron annihilation lifetime spectroscopy; physical ageing; phthalate; methyl methacrylate polymer; azo polymers; plasticization;

    Abstract : Irradiation of azobenzene induces isomerization between its trans- and cis forms. By introduction of azobenzene chromophores in polymers, it is possible to optically control a variety of polymer properties. The isomerization of azobenzene can be used to influence conformational, optical or surface properties of the poly mer material. READ MORE
