1. Nano- and mesoscale morphology evolution of metal films on weakly-interacting surfaces
Sammanfattning : Thin films are structures consisting of one or several nanoscale atomic layers of material that are used to either functionalize a surface or constitute components in more complex devices. Many properties of a film are closely related to its microstructure, which allows films to be tailored to meet specific technological requirements. LÄS MER
2. In-situ Studies of Spontaneous Potential Oscillations during Electrochemical Deposition of Copper and Cuprous Oxide
Sammanfattning : Self-oscillating behaviour in alkaline Cu(II)-lactate and -tartrate systems has been investigated by in-situ pH and confocal Raman spectroscopy measurements. Formation of Cu(II)-lactate and -tartrate complexes is a key factor underlying the self-oscillations. LÄS MER
3. Adsorption and surface reaction properties of synthesized magnetite nano-particles
Sammanfattning : The surface chemistry of inorganic materials is of great significance in a number of industrially important processes such as separation of ore by flotation, catalysis, water purification, paper coating and pharmaceutical industry. The purpose of this study has been firsly to develop a method for optimal synthesis of magnetite nanoparticles and secondly to utilize these particles as adsorbent in order to investigate their adsorption/desorption properties.

4. The Applicability of Geoelectrical Methods in Pre-Investigation for Construction in Rock
Sammanfattning : Construction in rock is associated with risks because knowledge of the geology and ground conditions is limited. Unforeseen rock conditions involve a large risk to the project and can in the end entail delays and extra costs. LÄS MER
5. On the Local Filtration Properties of LignoBoost lignin: Studies of the influence of xylan and ionic strength
Sammanfattning : Kraft pulping technology is currently the most commonly-used method for producing paper pulp from wood. A new and promising opportunity for Kraft pulp mills is to take a step towards becoming biorefineries by implementing technologies able to extract and convert the organic by-products, such as lignin, into a wide range of value-added products and chemicals.
