1. Computational Studies of Chemical Interactions: Molecules, Surfaces and Copper Corrosion
Detta är en avhandling från Stockholm : KTH Royal Institute of TechnologySammanfattning : The chemical bond – a corner stone in science and a prerequisite for life – is the focus of this thesis. Fundamental and applied aspects of chemical bonding are covered including the development of new computational methods for the characterization and rationalization of chemical interactions. LÄS MER
2. Effects of methyl jasmonate on chemical defenses of conifer seedlings in relation to feeding by Hylobius abietis
Detta är en avhandling från Stockholm : KTH Royal Institute of TechnologySammanfattning : The chemical elicitor methyl jasmonate (MeJA) could replace insecticides in Europe and Asia for protection of young conifers against the pine weevil (Hylobius abietis). This thesis mainly focuses on the effects of MeJA treatment on chemical defenses of conifers from seedling batches with documented field resistance. LÄS MER
3. Dynamic Sulfur Chemistry Screening, Evaluation and Catalysis
Detta är en avhandling från Stockholm : KTHSammanfattning : This thesis deals with the design, formation and evaluation of dynamic systems constructed by means of sulfur-containing reversible reactions, in organic and aqueous media and under mild conditions.In a first part, the synthesis of thioglycoside derivatives, constituting the biologically relevant starting components of the dynamic systems, is described.

4. Chemical signals in interactions between Hylobius abietis and associated bacteria
Detta är en avhandling från Stockholm : Kungliga tekniska högskolanSammanfattning : The pine weevil (Hylobius abietis L.) is one of the two topmost economically important insect pests in Swedish conifer forests. The damage increase in areas were the silvicultural practice is to use clear cuttings were the insects gather and breed. LÄS MER
5. Artificial Photosynthesis: Molecular Catalysts for Water Oxidation
Detta är en avhandling från Stockholm : KTH Royal Institute of TechnologySammanfattning : Artificial photosynthesis provides a promising solution to the future sustainable energy system. Water is the only suitably sufficient protons and electrons supplier by the reaction of water oxidation. However, this reaction is both kinetically and thermodynamically demanding, leading to a sluggish kinetics unless the introduction of a catalyst. LÄS MER
