6. Lean NOx reduction over silver-alumina catalysts - Aspects on synthesis, structure and activity
Abstract : The aim of this thesis is to increase the understanding of how to design highly active silver-alumina catalysts for selective catalytic reduction of NOx with hydrocarbons (HC-SCR) in oxygen excess at low temperatures (150-250 °C). Silver-alumina catalysts have been prepared using different methods, including a new unique preparation method developed during the thesis project. READ MORE

7. Freeze-Dried Wheat Gluten-Based Foams
Abstract : This thesis presents wheat gluten foams as an alternative to the available commercialfoams. Polymeric foams, like all plastics, are mostly made from petroleum, and this isaffecting the environment negatively with the emission of greenhouse gases and generation oflandfills. READ MORE

8. Design of solid dosage forms for mucosal vaccination - Investigations on the influence of excipients on product performance
Abstract : Most vaccines today are liquid formulations for parental administration. However, there are several drawbacks connected to these vaccines. Since injectable vaccines only induce systemic antibody responses, they are not effective against the various pathogens that affect mucosal surfaces with poor permeability for serum-derived antibodies, e.g. READ MORE

9. Starch Pickering Emulsions : Process and Encapsulation Stability
Abstract : The emulsion stabilization functionality of surfactants and biopolymers can be replaced by solid particles adsorbed at the interface, where they create a category of emulsions known as Pickering emulsions. Recently, health and environmental concerns have led to new market demand for natural, biodegradable and renewable sources of ingredients. READ MORE

10. Pharmaceutical Nanocomposites : Structure–Mobility–Functionality Relationships in the Amorphous State
Abstract : Amorphous materials are found in pharmaceutical formulations both as excipients and active ingredients. Indeed, these formulations are becoming an essential strategy for incorporating drugs into well-performing solid dosage forms. READ MORE
