3. 2. Two-Step Targeting for Effective Radionuclide Therapy : Preclinical Evaluation of 125I-labelled Anthracycline Delivered by Tumour Targeting Liposomes

   Författare :Amelie Fondell; Lars Gedda; Detlef Gabel; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radionuclide; Auger electrons; liposomes; targeting; tumour therapy; Biomedical Radiation Science; Biomedicinsk strålningsvetenskap;

   Sammanfattning : For the treatment of cancer, Auger-electron emitting radionuclides are strongly dependent on their close proximity to DNA to utilize the local therapeutic potential of the Auger electrons. This thesis investigates a two-step targeting approach that uses targeting liposomes for the delivery of an Auger-electron emitter, 125I, coupled to a DNA-binding compound, Comp1, to the tumour-cell DNA.

4. 3. Nuclear Dynamics in X-ray Absorption and Raman Scattering

   Författare :Ivaylo Minkov; Faris Gelmukhanov; Knut Borve; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; x-ray scattering; theory; simulations; recoil; Doppler effect; nuclear dynamics; Auger; XPS; Theoretical chemistry; Teoretisk kemi;

   Sammanfattning : This thesis presents theoretical studies of several x-ray spectroscopies - x-ray absorption, x-ray photoelectron emission, radiative and non-radiative resonant Raman scattering spectroscopy. The main focus point is investigating the influence of nuclear dynamics on these spectra for a variety of small molecules - naphthalene, biphenyl, ethylene, the water dimer, HCl, CO. LÄS MER

5. 4. Single-photon multiple ionisation of atoms and molecules investigated by coincidence spectroscopy : Site-specific effects in acetaldehyde and carbon dioxide

   Författare :Sergey Zagorodskikh; Raimund Feifel; Vitali Zhaunerchyk; Melanie Mucke; Maria Novella Piancastelli; Tom Field; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; acetaldehyde; carbon dioxide; xenon; electron correlation; double ionisation; triple ionisation; core-valence ionisation; site-specific Auger decay; multiple Auger decay; branching ratios; site-specific photodissociation; molecular rearrangement; time-of-flight multi-electron-ion coincidence spectroscopy; synchrotron radiation; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Sammanfattning : In this thesis, multiple ionisation processes of free atoms and molecules upon single photon absorption are studied by means of a versatile multi-electron-ion coincidence spectroscopy method based on a magnetic bottle, primarily in combination with synchrotron radiation. The latter offered the possibility to access not only valence but also core levels, revealing processes, which promote the target systems into different charge states. LÄS MER

7. 5. Models of Auger Neutralization and Tunneling at Metal Surfaces

   Författare :Tony Fondén; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : This thesis consists of a theoretical study of electron transfer at metal surfaces. It considers two types of electron transfer (electron tunneling and Auger neutralization) that both can be used as a spectroscopy to investigate the surface electronic structure. LÄS MER
