| Two dielectric spectrometers (Novocontrol concept 40) that include: high resolution (minimum tandelta~2x10-5), dielectric analyzer ALPHA-ANB with DC-Bias ±40 V (70 mA), with a frequency range from 3μHz to 20 MHz, active head sample cell ZGS, QUATRO temperature controller for measurements in the range from -160 to +400 oC. |
| In addition to T-dependent studies the lab at the UoI is equipped with a pressure-dependent dielectric spectroscopy for pressures in the range from 1 to 1000 atm. The UoI is recognized for the first studies of homopolymer (local and global polymer dynamics) and polymer blend dynamics (dynamic heterogeneity) at elevated pressures. In addition, pressure-dependent studies on polypeptides, performed solely at the UoI, were instrumental in clarifying the origin of the polypeptide liquid-to-glass transition. |

The rheometer (TA Instruments, model AR-G2) includes a magnetic bearing that allows for low nano-torque control (minimum torque: 0.01 μN∙m, maximum torque: 200 mN∙m, torque resolution: 0.1 nN∙m, displacement resolution: 25 nrad). It is equipped with Peltier plates, Environmental test chamber for temperature control from -160 to +600 oC, camera with image capture, small-angle light scattering unit for simultaneous rheology/scattering measurements (scattering angles from 6 to 26.8o, corresponding length scale from 1 to 4.6 μm). |
| Polarizing optical microscopy (Zeiss Axioskop 40, equipped with a video camera and a fast frame grabber) and with a Linkam temperature control unit (model THMS600, with TMS94 temperature programmer, temperature range -196 to 600 oC) will be employed in the Liquid Crystal/AAO studies. |
| DSC Q2000 (TA Instruments), temperature range: -180 to 500°C, DSC and TM-DSC. |
