  2. 1. Charge-transfer excitations and phtophysical properties of molecular building blocks

    Author : Oscar Rubio Pons; Yi Luo; Antonio Rizzo; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical chemistry; Photophysical porperties; CCSD; CASSCF; Teoretisk kemi; Theoretical chemistry; Teoretisk kemi;

    Abstract : This thesis reports a state-of-the-art theoretical study of photophysical properties of organic charge-transfer aromatic molecules. These molecules are building blocks of molecular functional materials used in modern photonics technology and play essential roles in chemistry and biology in general. READ MORE

  4. 2. Photophysical Properties of Organic and Organometallic molecules

    Author : Oscar Rubio Pons; KTH; []
    Keywords : molecule; two-photon absorption; singlet-triplet. spin-orbit; CASSCF; emission; phosphorescence; DFT; B3LYP;

    Abstract : Highly correlated quantum chemical methods have been appliedto study the photophysical properties of substituted benzenes.With the inclusion of spin-orbit coupling, the phosphorescencesof these molecules have been calculated usingMulti-CongurationalSelf- Consistent Field (MCSCF) quadraticresponse theory.

  5. 3. Simulations of Silicon Carbide Chemical Vapor Deposition

    Author : Örjan Danielsson; Erik Janzén; Anne Henry; Michel Pons; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Most of the modern electronics technology is based on the semiconducting material silicon. The increasing demands for smaller electronic devices with improved performance at lower costs drive the conventional silicon technology to its limits. READ MORE

  6. 4. Political Careers, Government Stability, and Electoral Cycles

    Author : Davide Cipullo; Eva Mörk; Luca Repetto; Vincent Pons; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Gender gaps; Self-selection; Political careers; Sticky floor; Voting; Government stability; Fragmentation; No-confidence votes; Bargaining; Brexit; Interest Groups; Forecaster behavior; Electoral cycles; Political selection; Macroeconomic forecasting;

    Abstract : Essay 1: This essay investigates the impact of voter support on the representation of women in the political profession. The empirical analysis exploits two-stage elections in the United States and Italy to hold the selection of candidates constant. READ MORE

  7. 5. Fear, Startle, and Fear-Potentiated Startle : Probing Emotion in the Human Brain

    Author : Anna Pissiota; Mats Fredrikson; Scott Rauch; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; anxiety; attention; brain; fear; fear-potentiated startle; human; neuroimaging; positron emission tomography; posttraumatic stress disorder; regional cerebral blood flow; startle; startle habituation; symptom provocation; Psykologi; Psychology; Psykologi; Psychology; psykologi;

    Abstract : The present thesis explored the neurobiological basis of three aspects of defense behaviors in humans. Positron emission tomography methodology was used, and changes in regional cerebral blood flow (rCBF) were measured as an index of neural activity. READ MORE
