11. Material distribution-based topology optimization for wave propagation problems
Sammanfattning : This thesis employs material distribution-based topology optimization for wave propagation problems. In the material distribution approach, we define a material indicator function that models the presence and absence of material in a design domain. LÄS MER
12. Graphene-based nanocomposites for electronics and photocatalysis
Sammanfattning : The development of future electronics depends on the availability of suitable functional materials. Printed electronics, for example, relies on access to highly conductive, inexpensive and printable materials, while strong light absorption and low carrier recombination rates are demanded in photocatalysis industry.

13. Nanoscale technologies for plasmon-assisted solar light harvesting and lipid membrane composites
Sammanfattning : Techniques for design, manipulation and characterization of nanoscale structures provide the basis for technological advances in areas like optics, electronics and biotechnology. The aim of this thesis is to develop new nanoscale methods and design schemes that extend the applicability of nanoscale devices. LÄS MER
14. Multifunctional Nanocellulose Composite Materials
Sammanfattning : Nanoparticles (NPs) are particles with more than one dimension between 1 and 100 nm. Because of their small size, they typically display different physical and chemical properties than the corresponding bulk materials. NPs have been used in many different applications, such as in electronics, optics, catalysis, and in biomedicine. LÄS MER
15. Development and Use of Optical Sensors in Modern Analytical Chemistry
Sammanfattning : A successful long-term high resolution imaging experiment in marine sediments was performed (17 days within the sample; Paper I). The time correlated calibration procedure was evolved to include parametric sigmoidal and logarithmic functions to provide three of the best performing (optical) pH sensors available up to date (Papers II, III and IV), precision of these sensors were in the 0.
