|This course emphasizes the practical applications of thermal analysis techniques in real world problem solving situations (commonly experienced in industrial and academic work environments). A brief background of the most common TA methods will be given; including differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA), thermomechanical analysis (TMA) and thermogravimetric analysis (TGA). Case studies illustrating how these techniques can be collectively used to solve industrial process and product development problems will be presented.
|This course emphasizes the practical applications of TA techniques in real world problem solving situations (commonly found in industrial and academic work environments). The subject matter is appropriate for technical professionals and managers with academic backgrounds in all fields of chemistry. Prior thermal analysis experience is not required.
