The goal | The aim of the course is that students learn their methodology, principles and application of modern chemical sensors in the evaluation and quality control of materials and processes. For future chemical engineers is essential to have an insight into the quality of air, water, materials and reaction medium in which the chemical reaction takes place. Chemical sensors, as well as primary sources of information, converts effects of chemical reaction into an electrical signal, enable the transfer and management of information systems . | |||
The outcome | Students will get the skills, knowledge and gain experience in chemical sensors, such specific devices that will be in engineering practice effectively applied in the analysis and quality control of materials and processes. Students will learn the art of selection and preparation of chemically active sensor coating (chemical compounds, sorbents, biomaterials) sensitive to the change of the measured quantities (mass, resistance, piezoelectricity, the absorption of radiation) that are functionally and selectively associated with material properties (density). | |||
