11. Optimization of the Sensor-Chip Surface in a Capacitive Biosensor for use in Aflatoxin Assays
Sammanfattning : The capacitive biosensor technology can be utilized for the analytical detection of a variety of different compounds. By employing the electrical double-layer principle, it is possible to detect very low concentrations of the target analyte due the methods inherent high sensitivity. LÄS MER
12. Biological Pre-filtration and Surface Water Treatment - Microbial barrier function and removal of natural inorganic and organic compounds
Sammanfattning : Waterworks in Sweden that apply conventional chemical surface water treatment are facing a number of challenges, including changes in raw water quality and demands for improved particle removal. The chief objective of this work was to evaluate biological pre-filtration for typical Swedish surface water, regarding the removal of natural organic matter, particles, iron and manganese, and taste and odour compounds.

13. Development of ATR-FTIR Kretschmann Spectroscopy for In situ Studies of Metal / Polymer Interfaces : and its Intergration with EIS for Exposure to Corrosive Conditions
Sammanfattning : The environmental stability of a metal / polymer interface is essential for the durability and mechanical stability of constructions in several important areas such as the automotive, offshore, building and aerospace industries. The protective capability of a polymer film is strongly connected to its barrier properties, but the transport of water and corrosive constituents through the polymer and the subsequent processes at the metal surface are complicated to analyse in detail.

14. Wear of coated and uncoated PCBN cutting tool used in turning and milling
Sammanfattning : This licentiate thesis has the main focus on evaluation of the wear of coated and uncoated polycrystalline cubic boron nitride cutting tool used in cutting operations against hardened steel. And to exam the surface finish and integrity of the work material used. LÄS MER
15. Valorization of Low Value Organic Waste by the use of Black Soldier Fly Larvae – Bioconversion of Sludge from the Pulp and Paper Industry
Sammanfattning : The current economic system is not sustainable, as it is based on a linear flow of resources from extraction, production, use and disposal. The linear flow of resources must be replaced with a circular flow where waste is seen as a resource. LÄS MER
