21. Aerosol Synthesis and Characterization of Heterogeneous Bimetallic Nanoparticles
Sammanfattning : As the proverbial noose tightens around humanity’s resource spending, research is focused on utilizing materials to their fullest potential. Nanotechnology is the ultimate way to economize by splitting objects into smaller parts and dispersing the material properties over greater surface to volume ratios. LÄS MER
22. Dinuclear Manganese Complexes for Artificial Photosynthesis : Synthesis and Properties
Sammanfattning : This thesis deals with the synthesis and characterisation of a series of dinuclear manganese complexes. Their ability to donate electrons to photo-generated ruthenium(III) has been investigated in flash photolysis experiments followed by EPR-spectroscopy. LÄS MER
23. Diurnal variation of stratospheric short-lived species
Sammanfattning : Diurnal variation of stratospheric short-lived speciesMaryam KhosraviChalmers University of TechnologyDepartment of Earth and Space SciencesAbstractThe depletion of ozone in the stratosphere has a direct impact on the amount of ultravioletradiation reaching the Earth’s surface. The ozone abundance and distributionis controlled by the photo-chemical reactions and catalytic cycles involving halogens(chlorine and bromine), odd hydrogen and odd nitrogen species as well as by atmospherictransport.

24. Radiative transfer in the absorption bands of oxygen : Studies of their significance in ozone chemistry and potential for aerosol remote sensing
Sammanfattning : Among the scientific topics of greatest public interest are the ozone question and climatic change. The discovery of the Antarctic ozone hole in 1985 and recognition of large scale ozone depletions in the northern hemisphere focused the world's attention on human induced changes in the atmosphere.

25. Compounds with Non-Buttressed Metal-Metal Bond between Platinum and Thallium. Model Systems for Photoinduced Two-Electron-Transfer
Sammanfattning : A new family of oligonuclear cyano compounds incorporatingtransition (Pt) and main group (Tl) metals bound with anon-buttressed Pt-Tl bond was synthesised in aqueous solution.The metal-metal linkage is formed in the reaction betweenplatinum and thallium in their stable oxidation forms, Pt(II)and Tl(III), orvice versa: Pt(IV) and Tl(I).
