The section for 'Electrochemical Materials' (EMA) researches on advanced, inorganic and organic materials for electrochemical and optical energy conversion and storage technologies. Through novel approaches to materials synthesis, surface modification, processing, and interface architectures, materials properties are tailored to achieve desired functionalities. This is supported by advanced characterization techniques to monitor the electrochemical, optical, and catalytic properties.Stricter regulations have been imposed on ships for SO2 emissions. One way to monitor the levels of SO2 emitted from ships is to use an electrochemical sensor. In this project an all solid state sensor based on a potassium ion conductor will be developed.
