1. 6. Provenance of the pre-Quaternary aeolian dust deposits of East Asia

   Författare :Katja Bohm; Thomas Stevens; Anu Kaakinen; Alex Pullen; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chinese Loess Plateau; Red Clay; mineral dust; sediment provenance; detrital zircon; detrital rutile; Neogene; Paleogene; Earth Science with specialization in Physical Geography; Geovetenskap med inriktning mot naturgeografi;

   Sammanfattning : Atmospheric mineral dust is a key component in the climate system, but its effect on and response to climate changes are poorly understood, especially over long timescales. This thesis investigates the sources of late Paleogene and Neogene dust deposits that formed under warmer-than-present global climates in the northern Chinese Loess Plateau (CLP) region in mid-latitude East Asia.

5. 9. Molecules and Clusters on Oxide Surfaces

   Författare :Evren Ataman; Synkrotronljusfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : In this thesis X-ray photoelectron spectroscopy, X-ray absorption spectroscopy, scanning tunneling microscopy,and density functional theory have been used to study the fundamental interactions between model oxidesurfaces and either organic, mixed organic/inorganic, or purely inorganic adsorbate layers. As model oxidesurfaces have served the rutile TiO2(110) surface and an in-situ grown iron oxide film supported by a Pt(111)surface. LÄS MER

7. 10. Infrared spectroscopy studies of adsorption and photochemistry on TiO2 surfaces : From single crystals to nanostructured materials

   Författare :Andreas Mattsson; Lars Österlund; Per-Anders Carlsson; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik;

   Sammanfattning : TiO2 based photocatalysis is a green nanotechnology that can be used for removal of pollutants from water and air, as well as making synthetic fuels from water and carbon dioxide. Said photocatalysis has received major research interests during the last decades. LÄS MER
