21. Microfluidics for High-Pressure Inertial Focusing : Focusing, Separation and Concentration of Micro and Sub-micron Particles
Sammanfattning : The birth of microsystems set the ground for technologies never imagined before, for it is not only the small size what characterizes the miniaturized systems, but unique phenomena arise in the micro scale. This thesis relates to one such unique phenomenon, inertial focusing, a phenomenon that occurs in microfluidic systems if very special conditions are met and that allows for fine manipulation of particles in fluid samples.

22. Biomimetic Formation of Calcium Phosphate Based Nanomaterials
Sammanfattning : The intercellular material in bone is a nanocomposite of aligned “hard” inorganics—calcium phosphate (CaP) platelets embedded in the long-range ordered “soft” organic collagen matrix. This elaborate structural arrangement redeems the weaknesses of the individual components (being soft protein or brittle mineral) and gives bone its excellent mechanical properties for the protection and support of our bodies.

23. High Clay Content Cellulose Nanocomposites for Mechanical Performance and Fire Retardancy
Sammanfattning : Materials based on wood can offer sustainable alternatives to fossil-based plastics and composites, and show interesting mechanical properties. However, the issue of their flammability is generally unresolved. In this thesis, eco-friendly, fire retardant clay-cellulose nanofibril materials are investigated. LÄS MER
24. Engineering Nanotherapeutic Strategies for Osteoarthritis Treatment
Sammanfattning : Osteoarthritis (OA), the most prevalent joint disorder, is characterized by the degeneration of cartilage tissue leading to pain, stiffness, and impaired mobility. Primarily affecting the elderly, OA can also impact athletes, postmenopausal women, and individuals with conditions like diabetes. LÄS MER
25. Innovations in nanomaterials for proton exchange membrane fuel cells
Sammanfattning : Hydrogen technologies are rapidly receiving increased attention as it offers a renewable energy alternative to the current petroleum-based fuel infrastructure, considering that continued large-scale use of such fossil fuels will lead to disastrous impacts on our environment. The proton exchange membrane fuel cell should play a significant role in a hydrogen economy since it enables convenient and direct conversion of hydrogen into electricity, thus allowing the use of hydrogen in applications particularly suited for the transportation industry.
