Tittel på prøveforelesning: "Late-stage isotopic labelling of pharmaceuticals" Tittel på avhandling: Targeting Kinases for (Radio) Pharmaceutical Development Sammendrag: Cancer remains one of the leading causes of death, and better tools to detect and treat it are urgently needed. In this project, I developed small molecules to stop cancer-related enzymes called kinases and others that carry radioactive labels to scan for brain tumors with high levels of kinases. Here, I describe the design, synthesis, and radioactive labeling of molecules for diagnosis and treatment. The molecules were tested in different models, from single cancer-related proteins and cells to animal models with cancer. This work may lead to improved cancer treatment and more accurate imaging – especially for aggressive brain tumors.

Conventional hydrotreatment requires substantial external hydrogen input and expensive noble- metal catalysts, leading to high costs and rapid catalyst deactivation. Co-pyrolysis of biomass with plastic waste offers a viable strategy to simultaneously upgrade bio-oil and valorize plastic residues through synergistic interactions. In this work, an environmentally benign and cost-effective clay-based catalyst was developed for catalytic co-processing of biomass and plastics. Catalytic co-pyrolysis of beechwood with various plastics achieved 60–80 wt% oxygen removal, producing oils with only 3–7 wt% residual oxygen. High yields of hydrocarbons in the naphtha and sustainable aviation fuel (SAF) ranges were obtained, demonstrating strong industrial potential. Mechanistic studies using DRIFTS and DFT revealed an oxygen-transfer pathway on the catalyst surface. Appropriately tuned acidity enabled oxygen migration from rigid biomass-derived oxygenates to more labile intermediates, facilitating efficient deoxygenation while maximizing carbon retention. This study provides both a practical route to carbon-neutral fuel precursors and fundamental insights into biomass–plastic co-pyrolysis, supporting the development of next-generation catalysts for sustainable fuel production.
