11. Optical Imaging and Spectroscopy of Metal Nanostructures
Sammanfattning : Noble metal structures with size in the sub 100 nm range exhibit extraordinary optical properties due to collective oscillations of conduction electrons, the surface plasmon resonances (SPR). The most remarkable feature of these structures is the ability to redistribute electromagnetic radiation and concentrate strong fields near the surface. LÄS MER

Sammanfattning : .... LÄS MER
13. Functionalized Biomaterial Surfaces by Micro- and Nanofabrication
Sammanfattning : In the field of biomaterials, well-defined nano- and micropatterns or features at material surfaces can serve both as models for investigating material-biosystem interactions and as functional features for inducing, hindering or measuring specific bioreactions or biologic responses. Important bioreactions include protein adsorption and conformation, cell attachment and function, and adhesion and function of organized tissues or whole organisms. LÄS MER
14. Elucidating Chemical and Electrochemical Side-Reaction Mechanisms in Li-ion Batteries
Sammanfattning : Lithium-ion batteries constitute a leading technology that plays a major role in the transition towards sustainable transportation and power generation. The stability of modern batteries relies on a passivation layer formed on the negative electrode known as the solid electrolyte interphase (SEI). LÄS MER
15. Optical properties of silver nanostructures prepared by electron beam lithography
Sammanfattning : In this thesis, electron beam lithography (EBL) has been used to fabricate substrates for studies of nanoparticle optics, in particular for the investigation of noble metal nanoparticles and their tunable optical properties. The strong interaction of metal nanoparticles with light has its origin in the resonant excitation of collective oscillations of conduction electrons, so called localized surface plasmons (LSP).
