21. Nanoplasmonics for solar cells
Abstract : The main source of our energy system, the fossil fuels, will eventually be depleted and also pose environmental and climate hazards. There is thus a need for alternative, renewable energy sources. Solar (photovoltaic) cells will play an important role as one of them. READ MORE

22. Near-field scanning optical microscopy and fractal characterization with atomic force microscopy and other methods
Abstract : This thesis is devoted to the development of near-field scanning optical microscopy (NSOM) for aqueous solutions and to fractal characterization of steel surfaces with atomic force microscopy (AFM) and other methods. NSOM combines optical properties from a light microscope and the technique of scanning probe microscopy, SPM (invented in the early 1980’s). READ MORE

23. Nanoplasmonic Enhancement of Photon-to-Electron Conversion in Functionalized Iron Oxide Photoanodes
Abstract : The ever increasing energy demand of modern society clashes with the accelerating depletion of the fossil fuels from which most of this energy is taken today. Moreover, fossil fuels consumption poses a severe threat on the Earth’s environment and climate through global warming. READ MORE

24. Photoelectrochemical Processes on Fe2O3 Based Model Anodes
Abstract : One possibility to partially satisfy the ever-increasing energy needs of modern society, without compromising the Earth’s environment through e.g. global warming, consists in harvesting solar energy and storing it as hydrogen produced from water splitting. This can potentially be achieved on a large scale using photoelectrochemical (PEC) cells. READ MORE

25. Microscale electrostatic 2D- and 3D-printing
Abstract : There has been an explosive interest in 2D- and 3D-printing production methods during the past decade due to the ability to rapidly create almost arbitrary structures. Challenges of printing control are encountered for instance when pushing the methods to produce smaller and smaller structures. READ MORE
