9.12. Optical measurements of complex liquids

 Public examination of a doctoral dissertation in the field of physics

Doctoral candidate: M.Sc. Ville Kontturi 

Date and venue: 9.12.2011 at 12 noon, M102 Metria, Joensuun kampus 

ABSTRACT 

This thesis is focused on novel measurement methods of the optical properties of complex liquids. Complex liquids are liquids which contain solid particles, gas bubbles or both. To obtain the optical properties of complex liquids, novel techniques are introduced to data analysis and measurement setups. Data analysis techniques are presented to obtain the colour of dry ink, quality of biofuels, number density of metallic nanoparticles, the optical properties of nanoparticles and the complex refractive index of colloidal gold. A novel measurement setup is presented for obtaining the turbidity of liquids from absorbing liquids. 

The doctoral dissertation of M.Sc. Ville Kontturi entitled “Optical measurements of complex liquids” will be examined at the Faculty of Science and Forestry. The opponent in the public examination is Docent Erik Vartiainen of the Lappeenranta University of Technology and the custos is Professor Kai-Erik Peiponen of the University of Eastern Finland.
