1. Infrared Emittance of Paper : Method Development, Measurements and Application
Abstract : Thermography is a non-destructive technique which uses infrared radiation to obtain the temperature distribution of an object. The technique is increasingly used in the pulp and paper industry. To convert the detected infrared radiation to a temperature, the emittance of the material must be known. READ MORE

2. The spectral reflectance of coniferous tree stands and of barley influenced by stress : an analysis of field measured spectral data
Abstract : This thesis focuses on the spectral signatures for vegetation. Knowledge about the spectral characteristics of different vegetation types is imperative for an efficient use of existing remote sensing systems, and also to provide guidelines for sensor development. READ MORE

3. Preparation and Characterization of Sputter Deposited Spectrally Selective Solar Absorbers
Abstract : The optical efficiency of a commercially available sputter deposited spectrally selective solar absorber was improved. The main purposes were to decrease the thermal emittance, increase the solar absorbtance of the absorber and to protect the substrate from degradation due to environmental influence. READ MORE

4. Model catalysts studied by x-rays, visible and infrared light
Abstract : This work is focused on the study of transition metal model catalysts for gas-phase heterogeneous catalysis, studied with light-based in-situ and operando techniques.Metallic model catalysts, such as Palladium (Pd) and Iridium (Ir) single crystals and in minor part deposited Rhodium (Rh), were studied using a combination of x-ray and non x-ray techniques.

5. Crystallization of Parabens : Thermodynamics, Nucleation and Processing
Abstract : In this work, the solubility of butyl paraben in 7 pure solvents and in 5 different ethanol-water mixtures has been determined from 1 ˚C to 50 ˚C. The solubility of ethyl paraben and propyl paraben in various solvents has been determined at 10 ˚C. READ MORE
