  1. 11. Theoretical Design of Molecular Photonic Materials

    Författare :Yanhua Wang; Yi Luo; David Beljonne; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optical property; Molecular material; Solvent environment; Nuclear vibrations; Aggregation effect; Theoretical chemistry; Teoretisk kemi;

    Sammanfattning : This thesis presents a theoretical study on optical properties of molecular materials. Special emphasis has been put on the influence of solvent environment, nuclear vibrations, and aggregation effects on molecular properties like linear and nonlinear polarizabilities, one- and two-photon absorption probabilities.

  4. 13. The effect of radiolysis of BTBP type molecules on distribution ratios

    Författare :Anna Fermvik; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; radiolysis; transmutation; partitioning; BTBP; solvent extraction; lanthanides; actinides;

    Sammanfattning : Partitioning and transmutation of spent nuclear fuel enables a decrease in the long term radiotoxicity and volume of the waste to be disposed. By transforming the long-lived nuclides into shorter-lived or even stable ones, the time required for a final repository to be regarded safe for the environment can decrease from 100,000 years to less than 1,000 years.

  5. 14. CO2 Separation - from Aqueous Amine Solvent to Ionic Liquid-based solvent

    Författare :Nan Wang; Xiaoyan Ji; James Glynn; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : CO2 separation is one of the most important roles in CO2 mitigation target as many human production activities (e.g., cement, iron and steel, and biogas productions) cause CO2 emissions. The solvent-based absorption is the most mature technology for CO2 separation, where different solvents capture CO2 either in chemical or physical absorptions. LÄS MER

  7. 15. Film morphology for organic solar cells : Effect of Solubility and Gravity Conditions

    Författare :Ishita Jalan; Jan van Stam; Leif Ericsson; Stela Andrea Muntean; Philippe Leclère; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry; Chemistry - Physical Chemistry; Kemi - fysikalisk kemi;

    Sammanfattning : Organic photovoltaics is a promising environmentally friendly technology, due to their printability, light-weight nature and mechanical flexibility, and the possibility to use off-grid. Research and development in this field has resulted in power conversion efficiencies of over 15%. LÄS MER
