Kemilaborationens bidrag till förståelse - högskolestudentens perspektiv -
(2008-11-14)Den här studien har som mål att försöka förstå hur laborationen bidrar till att underlätta studenternas kognitiva arbete att förstå teorin ingående i deras första kemikurs på akademisk nivå. Empirin har framförallt sökt ... -
Lidar Studies of Tropospheric Aerosols and Clouds
(2008-09-22)An improved description of aerosol and cloud processes is a prerequisite for successful prediction of future climate change. The climate on Earth is controlled by the radiation budget, i.e. the relation between the radiation ... -
Ligand Dependent Regioselectivity in Palladium Mediated Allylic Alkylation
(2010-09-17)In this thesis, different aspects on ligand dependent regioselectivity in palladium mediated allylic alkylation have been studied. It is believed that the regioselectivity is a result of nucleophilic attack trans to ... -
Limonene Hydroperoxides in Allergic Contact Dermatitis. Radical Formation, Sensitizing Capacity and Immunogenic Complex Formation.
(2009-04-24)Contact allergy to fragrance compounds is an increasing problem in the western countries today. R-Limonene is one of the most common fragrance compounds; it is used in hygiene products and cosmetics as well as in industrial ... -
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 ... -
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 ... -
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 ... -
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 ... -
Proton conductivity in acceptor-doped lanthanide based pyrochlore oxides
(2009-11-06)A high interest in developing new materials for SOFC applications in the temperature range of approximately 200–500 degrees C has been growing lately. The lower activation energies for proton (H+) mobility can give higher ... -
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 ... -
Samarium(II)-mediated reactions in organic synthesis - method development and mechanistic investigation
(2010-04-07)This thesis describes the development of methods using divalent samarium reagents in organic synthesis. The main focus is placed on functional group reductions, but reductive formation of carbon-carbon bonds has also been ... -
Structure and Function of Aqua(glycero)porins - A Path to Drug Design
(2011-04-05)Membrane proteins are a major class of the drug targets. Rational design of drugs requires knowledge about the structure and function of these proteins. Working with membrane proteins, however, is experimentally challenging ... -
Structure, phase behavior, and dynamics of colloidal systems characterized by strong, short- and moderate-ranged attractions: a computational study
(2010-11-03)Attractions between colloidal particles are often so strong that non-equilibrium behavior results. However, dissolved non-adsorbing polymer can be added to give a weak attraction between particles so that equilibrium phase ... -
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 ... -
Theoretical Investigations of the Role of Ion-Ion Correlations and Ion-Specific Interactions in Electric Double Layers
(2009-09-10)Electric double layers are ubiquitous, arising in some form in almost every situation involving an interface with an aqueous electrolyte solution. In order to gain insight into the behavior of electrolytes and electric ...
