21. Pharmaceutical binders and their function in directly compressed tablets : Mechanistic studies on the effect of dry binders on mechanical strength, pore structure and disintegration of tablets
Sammanfattning : In this thesis, the strength-enhancing mechanisms of dry binders in direct compression were studied. The systems investigated were binary mixtures containing various compounds and binders. Among the binders used were a series of different molecular weights of polyethylene glycol. LÄS MER
22. The void : Urban wasteland as political space
Sammanfattning : The rugged field and group of trees between housing estates or next to the railroad tracks, the left-over space of deserted industrial areas, the vacant demolition site of a central city block – they could all be termed ‘urban voids’. However, they are often anything but voids, in a literal sense, as they are not empty, or deserted. LÄS MER
23. Single Copper Nanoparticle Oxidation
Sammanfattning : Cu nanoparticles are commonly used in microelectronic devices and as catalysts in, for example, methanol synthesis and methanol steam reforming reactions. However, Cu nanoparticles are prone to oxidation. LÄS MER
24. Initial Oxidation of β-NiAl(Pt) Coatings and Model Alloys
Sammanfattning : The aim of this work was to investigate the oxidation properties of NiAl coatings and model materials during high temperature oxidation. One of the important issues was to elucidate the beneficial role of Pt additions. A better understanding of the involved processes provides a key for the further improvement of the coatings performance. LÄS MER
25. Business Model Design for Social Goods and Services in Developing Economies
Sammanfattning : Over the past decade there have been increasing calls for alternative ways of tackling poverty problems in developing economies. Rather than aid or charity approaches that have traditionally dominated this area, an alternative line of discussion around base-of-the-pyramid approaches has emerged which emphasizes the role of innovation and pro-poor entrepreneurship.
