1. 6. X-ray Spectroscopy of Molecules Driven by Strong IR Fields

   Författare :Freddy Fernandes Guimaraes; Faris Gelmukhanov; Michael Meyer; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Theoretical chemistry; Teoretisk kemi;

   Sammanfattning : The current thesis deals with one important branch of the physics of ultrafast processes, namely modeling of femtosecond nuclear dynamics. We suggest a new type of time resolved spectroscopy, the phase sensitive infrared-x-ray pump probe spectroscopy, which combines rich opportunities of IR laser techniques in quantum control of molecular systems with the site selectivity of x-rays.

3. 7. Electron-nuclear Dynamics in Nonlinear Optics and X-ray spectroscopy

   Författare :Sergey Polyutov; Faris Gelmukhanov; Patrick Norman; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Biokemi;

   Sammanfattning : This thesis is devoted to theoretical studies of the role of nuclear vibrations on nonlinear and linear absorption, pulse propagation, and resonant scattering of light. The molecular parameters needed for the simulations are obtained through suitable quantum chemical calculations, which are compared with available experimental data. LÄS MER

4. 8. Resonant and Non-Resonant Electron Spectroscopy of Free Molecules and Free Clusters

   Författare :Raimund Feifel; Michael Meyer; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; fysik; Physics;

   Sammanfattning : Resonant electron spectroscopy has been performed on the diatomic molecules CO, N2 and HCl. Core-excitations were made to bound and dissociative intermediate electronic states. Fundamental interference phenomena are observed and discussed in the framework of ”X-ray Raman Scattering Theory”. LÄS MER

5. 9. Covalent functionalization of carbon nanomaterials for bioelectrochemical applications

   Författare :Naoual Allali; Alexander Soldatov; Manuel Dossot; Victor Mamane; Silvia Giordani; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Experimentell fysik; Experimental Physics;

   Sammanfattning : Carbon nanotubes (CTNs) are renowned for their exceptional electronic and mechanical properties. Their structure can be considered as rolling up a graphene sheet along a specific crystallographic direction, leading to a 1D confinement of the electronic wavefunction of the delocalized electrons along the perimeter of the cylindrical structure thus obtained.
