| Short Description: Universal Mechanical Spectrometer for linear and nonlinear viscoelastic properties of matter in wide Temperature (-100 °C to 300 °C) and frequency (0.001 to 100 Hz) ranges. | Picture of the Equipment
| |
| Available Experiments/Techniques: Dynamic moduli in oscillatory shear flow, viscositis in shear and extensional flow, all types of stress controlled experiments including retardation function determination. | ||
| Special Equipment: add on to measure extensional viscosity of high viscous and high elastic materials | ||
| Measurements on the equipment are currently done by: | Students after Introduction Students after extensive training Trained scientific service personal | |
| Recent Publications, where this instrument was important (citation): | C. Iacob, J. Sangoro, A. Serghei, S. Naumov, Y. Korth, J. Kärger, C. Friedrich, and F. Kremer Universal scaling of charge transport in glass-forming ionic liquids, Phys Chem Chem Phys 11 (2009), 913-916. | |
| Typical problems that may be solved with this instrument: | -Structure-rheological properties relationships for polymeric materials, including composites, ionic & molecular liquids. -Determination of characteristic viscositis and moduli of matter, relaxation time spectra -visualization of flow induced structures -rheological properties as influenced by magnetical or electrical fields | |
