This thesis describes the development and characterisation of a novel biomembrane model suitable for electrochemical investigation, and its applicability in studies of biologically related phenomena. The model system consists of a lipid monolayer, deposited at a polarisable liquid – liquid interface with the Langmuir – Blodgett technique. Combinations of ac and dc electrochemical techniques wit...

The reliability of portable electronic devices was studied by applying standardized test procedures for test vehicles that represent the technologies and lead-free materials typically used in novel portable products. Thermal cycling and drop testing are commonly used because they reveal the failure modes and mechanisms that portable devices experience in operational environments. A large number...

The aim of this study was to develop a biotechnological production process for xylitol. The xylitol production characteristics of Candida millerii, Candida guilliermondii and Candida tropicalis were compared. C. tropicalis was the best xylitol producer. A volumetric productivity of 5.7 g xylitol L h was achieved with 69 % yield from D-xylose on a mineral medium with a modified repeated fed batc...
