1. 6. Cellulose Nanofibril Networks and Composites : Preparation, Structure and Properties

   Författare :Marielle Henriksson; Lars Berglund; Alain Dufresne; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cellulose nanocomposites; microfibrillated cellulose; nanofibrils; biofibers; mechanical properties; deformation mechanisms; molar mass; endoglucanase; Materials science; Teknisk materialvetenskap;

   Sammanfattning : Träbaserade cellulosananofibriller är intressanta som förstärkande fas i polymera nanokompositer; detta främst på grund av den kristallina cellulosans höga styvhet och på grund av nanofibrillernas förmåga att bilda nätverk. Cellulosananofibriller kan användas i form av mikrokristallin cellulosa, MCC, som har lågt längd/diameter förhållande, eller i form av mikrofibrillerad cellulosa, MFC, med högt längd/diameter förhållande.

3. 7. Computational Insights on Functional Materials for Clean Energy Storage : Modeling, Structure and Thermodynamics

   Författare :Tanveer Hussain; Rajeev Ahuja; Caetano R. Miranda; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Density functional theory; Molecular dynamics; Hydrogen storage; Chemisorption; Physisorption; Functionalization; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Sammanfattning : The exponential increase in the demands of world’s energy and the devastating effects of current fossil fuels based sources has forced us to reduce our dependence on the current sources as well as finding cleaner, cheaper and renewable alternates. Being abundant, efficient and renewable, hydrogen can be opted as the best possible replacement of the diminishing and harmful fossil fuels. LÄS MER

4. 8. Prevention of type 2 diabetes : modeling the cost-effectiveness of diabetes prevention

   Författare :Anne Neumann; Lars Lindholm; Katarina Steen Carlsson; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; type 2 diabetes mellitus; prevention; health economics; Markov modeling; risk equations; health-related quality of life; lifestyle modification; pre-diabetic states; cost-effectiveness; Västerbotten Intervention Programme;

   Sammanfattning : Background: Diabetes is a common and costly disease that is expected to continue even to grow in prevalence and health expenditures over the coming decades. Type 2 diabetes is the most common diabetes type and is characterized by insulin resistance and relative insulin deficiency. LÄS MER

   Sammanfattning : This thesis consists of an introductory chapter and four self-contained essays on financial performance and capital structure. Essay I assesses the strength of strategic inputs into profitability among firms within several sub-sectors within the industrial service sector in the U.S. and Sweden. LÄS MER

7. 10. In pursuit of next generation photovoltaics : An electronic structure study of emerging solar cell materials

   Författare :Axel Erbing; Michael Odelius; David Scanlon; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Solar cells; computational physics; density functional theory; electronic structure; molecular dynamics; Solceller; beräkningsfysik; täthetsfunktionalteori; elektronstruktur; molekyldynamik; Theoretical Physics; teoretisk fysik;

   Sammanfattning : The development of a new generation of photovoltaic technologies is an important task in order to increase the production of clean energy. Perovskite solar cells, with an exceptionally rapid development over the last decade, have transformed into perhaps the most promising candidate to provide a low-cost alternative to conventional cells.
