  1. 6. Probing Catalytic Reaction Mechanisms of Biomimetic Diiron Complexes through Time-resolved Absorption Spectroscopy

    Författare :Shihuai Wang; Leif Hammarström; Reiner Lomoth; Jillian Dempsey; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Artificial photosynthesis; Biomimetic catalysts; H2 formation; Catalytic intermediates;

    Sammanfattning : Directed design of improved molecular catalysts for hydrogen evolution reactions relies on rational benchmarking based on a detailed understanding about the mechanism of catalysis. Specifically, investigation of multi-electron redox catalysis, with structural characterization of catalytic intermediates, combined with the kinetics of their transformations, can reveal the rate-limiting step of the overall reaction, possible degradation pathways and the function of structural motives.

  3. 7. Ions colliding with molecules and molecular clusters : fragmentation and growth processes

    Författare :Tao Chen; Henrik Cederquist; Hutton Roger; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PAH; H2; C60; fragmentation; fysik; Physics;

    Sammanfattning : In this work we will discuss fragmentation and molecular growth processes in collisions of Polycyclic Aromatic Hydrocarbon (PAH) molecules, fullerenes, or their clusters with atoms or atomic ions. Simple collision models as well as molecular structure calculations are used to aid the interpretations of the present and other experimental results. LÄS MER

  4. 8. On performance limitations of large-scale networks with distributed feedback control

    Författare :Emma Tegling; Henrik Sandberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Networked control systems; microgrids; platooning; vehicular formation; multi-agent systems; H2 norms; fundamental limitations; consensus; Distributed control; large-scale networks; oscillator networks; power networks; power system dynamics; system performance; spatially invariant systems; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : We address the question of performance of large-scale networks with distributed feedback control. We consider networked dynamical systems with single and double integrator dynamics, subject to distributed disturbances. We focus on two types of problems. First, we consider problems modeled over regular lattice structures. LÄS MER

  7. 10. Formation of small molecules in space through the process of radiative association

    Författare :Daria Jones; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; astrochemistry; reaction rate constants; formation of molecules; physical chemistry;

    Sammanfattning : This thesis is dedicated to calculating the reaction rate constants for the formation of molecules through radiative association (RA) under interstellar conditions. The molecules that have been studied are CH, AlCl, Na+ − H2 and Al+ − H2. LÄS MER
