1. Role of alloying elements in Mo5Si3 intermetallics
Sammanfattning : The role of alloying elements in the intermetallic compound Mo5Si3 was studied in the alloying systems Mo5-xMxSi3 (M = Cr, Ti, Nb, Ni, or Co, x = 0.5-2). The effects of the alloying elements were examined by characterising the microstructures and identifying the resulting phases. In the case of Cr and Nb alloying, a solubility of 25% (at. LÄS MER
2. Surface and porous structure of pigment coatings : Interactions with flexographic ink and effects on print quality
Sammanfattning : Each day, we are confronted with a large amount of more or less important information that we have to consider, and even in our digital society we need paper for communication, documentation and education. Much of the paper we use or are confronted by in our daily life, such as newspapers, books and packages, contains printed images or texts, and the appearance of both the print and the supporting surface is important.

3. Epigenetic changes and immunological features of chronic obstructive pulmonary disease
Sammanfattning : Background: Chronic obstructive pulmonary disease (COPD) is a heterogenous and chronic inflammatory syndrome with the lungs as its main target organ. Clinically, COPD is characterized by airflow limitation, chronic respiratory symptoms, and many extrapulmonary comorbidities. LÄS MER

The thesis consists of four essays that address the issues of firm disclosure and the relevance of information for analysts and investors in the capital market. LÄS MER
5. Printability and Ink-Coating Interactions in Inkjet Printing
Sammanfattning : Inkjet is a digital printing process where the ink is ejected directly onto a substrate from a jet device driven by an electronic signal. Most inkjet inks have a low viscosity and a low surface tension, which put high demands on the coating layer’s porosity and absorbency characteristics. LÄS MER
