Fluxes and transformation of carbon in the Siberian shelf seas under changing environment
(2012-05-16)The Arctic is especially vulnerable to the increased air temperature caused by emissions of greenhouse gases to the atmosphere, carbon dioxide being one of them. In this thesis, both fieldwork and modelling of the East ... -
Hydrolytic Synthesis and Physicochemical Properties of TiO2 Nanoparticles: Fundamentals and Applications
(2012-04-13)Titanium dioxide (TiO2) nanoparticles were synthesized via the hydrolysis of TiCl4 in order to produce clean, surfactant-free oxide surfaces. By controlling the synthesis and aging conditions, stable particles with ... -
MECHANISTIC INVESTIGATIONS OF TRANSITION METAL CATALYZED REACTIONS
(2011-12-14)Transition metal catalyzed reactions have had a large impact on the human progress for the last century. Several extremely important areas, such as the agricultural industry and the plastic industry, have benefited from ... -
Chiral Lithium N,P-amide Complexes. Synthesis, Applications and Structural Studies by NMR and DFT.
(2011-11-28)Enantiospecific synthesis reactions are of intense interest, owing to the increasing request for enantiopure compounds in both research and industry. Lithium amides containing a secondary chelating group are a class of ... -
Influence of resuspension on sediment-water solute exchange and particle transport in marine environments
(2011-11-24)Marine sediments contain a large pool of nutrients, which if released would contribute to increased eutrophication, in spite of decreased nutrient loads from land and atmosphere. Resuspension is a process, which might ... -
New insights in contact allergy and drug delivery. A study of formulation effects and hapten targets in skin using two-photon fluorescence microscopy
(2011-11-08)The skin is a remarkable barrier, protecting us from invasion of e.g. harmful microorganisms and UV-radiation. However, the skin is not adopted to resist repeated exposure to the multitude of xenobiotics introduced into ... -
Conformational Dynamics of Rhodopsins Visualized by Time-resolved Wide Angle X-ray Scattering
(2011-10-27)Rhodopsins are a family of light-sensitive proteins found in the cellular membranes of a wide range of living organisms. These membrane proteins share a common molecular architecture and are able to use light energy ... -
Physical properties and processes of secondary organic aerosol and its constituents
(2011-10-27)Atmospheric aerosol particles are involved in several important processes including the formation of clouds and precipitation. A considerable fraction of the ambient aerosol mass consists of organic compounds of both primary ... -
Experimental studies of cluster ions containing water, ammonia, pyridine and bisulphate
(2011-10-06)Molecular cluster ions are fascinating subjects of study. Bridging the size gap between molecules and bulk, they often display non-trivial size dependent behaviour and properties. As an example, for some cluster types there ... -
Synthesis of Novel Inhibitors of IdeS, a Bacterial Cysteine Protease Including Studies of Stereoselective Reductive Aminations
(2011-09-30)Abstract The cysteine protease IdeS is an IgG degrading enzyme secreted by the bacterium Streptococcus pyogenes to evade the human immune system. In this thesis several inhibitors of IdeS have been synthesized and ... -
Chemical and Dermatological Aspects of UV-absorbing Compounds
(2011-09-27)ABSTRACT The sun’s UV radiation is necessary for the existence of life on earth. However, too much UV exposure can lead to the development of skin cancer. Therefore, sunscreens are often used by the general population ... -
On the Electrolyte Induced Aggregation of Concentrated Silica Dispersions - An Experimental Investigation Using the Electrospray Technique
(2011-09-08)Gels are weak, solid-like structures that arise when colloidal particles aggregate to form a network of particle clusters. A variety of colloidal systems that are important scientifically as well as in industrial applications ... -
Analysis of phospholipids in cellular membranes with LC and imaging mass spectrometry
(2011-05-20)Imaging mass spectrometry enables the creation of molecule specific images from the surface of a solid sample in vacuum. To solve the issue of bringing single cells into vacuum without altering their native distribution ... -
Colloidal interactions obtained from total internal reflection microscopy measurements and scattering data
(2011-05-18)The scattering of radiation can be used to extract information about the interactions between colloidal (10^{-7}-10^{-3} cm radius) particles suspended in liquids. As colloidal interactions incorporate entropic effects ... -
Integrated biomechanical, electronic and topographic characterization of titanium dental implants
(2011-05-11)Titanium dental implants are medical devices used to restore the function entailed with the loss of one or several teeth. To obtain successful function over long periods, the dental implants must be sufficiently anchored ... -
Regulation of electron donation to photosystem 1
(2011-05-09)Photosynthesis is the process where energy from light is used to catalyze the formation of energy-rich molecules such as NADPH and ATP. These reactions are in fact the result of a long series of electron-transfer reactions ... -
AQUAPORINS: Production Optimization and Characterization
(2011-05-05)Aquaporins are water facilitating proteins embedded in the cellular membranes. Such channels have been identified in almost every living organism – including humans. They are vital molecules and their malfunction can lead ... -
Absolute Asymmetric Synthesis
(2011-04-18)Absolute asymmetric synthesis is the synthesis of optically active products from achiral or racemic precursors only. This has generally been regarded as impossible and is relevant in the discussion of the origins of ... -
Homochiral Crystals for Selective Synthesis
(2011-04-13)Six new coordination compounds were prepared from monodentate sulfide ligands and copper(I) halides and their crystal structures were determined by single-crystal X-ray diffraction. The aim was to prepare coordination polymers ...
