1. Water film-mediated mineralogical transformations and photocatalytic reactions
Sammanfattning : Mineral particles capture water vapor in the atmosphere in the form of water films that are only few monolayers thick. Water films form nanoscale hydration environments that mediate a wide range of important reactions in nature and technology. LÄS MER
2. Thin water and ice films on minerals : a molecular level study
Sammanfattning : Minerals in Earth’s crust and suspended in the atmosphere form water or ice films as thin as a few nanometers to as thick as a few micrometers, and beyond. Mineral-bound water and ice films in terrestrial systems (e.g. LÄS MER
3. Pilicides and Curlicides : Design, synthesis, and evaluation of novel antibacterial agents targeting bacterial virulence
Sammanfattning : New strategies are needed to counter the growing problem of bacterial resistance to antibiotics. One such strategy is to design compounds that target bacterial virulence, which could work separately or in concert with conventional bacteriostatic or bactericidal antibiotics. LÄS MER
4. Synthesis of Potential Inhibitors Against HIV
Sammanfattning : This thesis describes the syntheses of various potential inhibitors of HIV, e.g. some 3´-hydroxymethyl-substituted carbocyclic nucleoside analogues as reverse transcriptase inhibitors and some symmetry-based peptidomimetics as protease inhibitors. LÄS MER
5. Unraveling the importance of thiol compounds on mercury speciation, uptake and transformation by the iron-reducer Geobacter sulfurreducens
Sammanfattning : The biogenic methylation of inorganic, divalent mercury (Hg(II)) by methylating microorganisms leads to formation and bioaccumulation of monomethyl mercury (MeHg) in the environment and can cause severe damage to ecosystems and human health. Diverse microorganisms carry the gene sequence hgcAB and are able to methylate Hg(II) intracellularly. LÄS MER
