Modulated Temperature Differential Scanning Calorimetry (MTDSC)

Modulated Temperature Differential Scanning Calorimetry (MTDSC)

FYSC has been actively participating in the development of MTDSC instruments and methods since the introduction of the modulated dsc by TA Instruments and Dr. Mike Reading in 1992, developing methods for studying cure and vitrification in reacting polymer systems (thermosets), phase separation and remixing in polymer blends and polymer solutions,...

Rapid-Heat Cool Calorimetry (RHC)

Rapid-Heat Cool Calorimetry (RHC)

Rapid-Heat Cool calorimeter (RHC) developed by TA Instruments RHC in 2007. This instrument is one of 5 prototypes (worldwide) and is not commercially available. The instrument is equipped with a liquid nitrogen cooling system and permits high quality DSC experiments at heating and cooling rates of up to 2500 K/min between -170°C and 400°C on samples of 50-1000 µg.

Chip Calorimetry

Chip Calorimetry

Fast scanning chip calorimetery as used in the FYSC group was developed at the Polymer Physics Group of Rostock University. The combination of thin-membrane chips and sample masses in the order of nanograms allows for much higher scanning rates, up to 1000 000 K/s, by strongly reducing the thermal mass.

Atomic Force Microscopy (AFM)

Atomic Force Microscopy (AFM)

AFM is an imaging technique based on the interaction between the sample and a tiny probe, called the cantilever. The cantilever contains a sharp tip, which is the actual part that will interact with the sample surface. By scanning a sample surface and plotting how these interactions change in function of the x-y position an image can be obtained which plots several physical properties such as e.g ...

Dynamic Mechanical Analysis (DMA)

Dynamic Mechanical Analysis (DMA)

In Dynamic Mechanical Analysis (DMA) a small sinusoidal perturbation is superimposed on a static stress, permitting the measurement of the viscoelastic response of solid materials, characterized by the storage modulus, loss modulus and the loss angle. DMA is a very sensitive technique for studying glass transitions. The TA Instruments Q800 DMA equipped with a liquid nitrogen cooling can be used ...

Dynamic Rheometry (DR)

Dynamic Rheometry (DR)

Dynamic rheometry or small angle oscillatory shear viscometry is a technique for studying the viscoelastic behaviour of materials. It is most suited for studying liquids, gels, and soft rubbers. For materials having a higher stiffness, DMA is more suitable. In Dynamic rheometry (DR) a sample is placed between two plates, small sinusoidal displacement is applied to the upper plate, and the ...

Thermomechanical Analysis (TMA)

Thermomechanical analysis is the measurement of height of a probe placed on a sample using a small or constant force, while exposing the sample to a selected temperature program. This technique can be used to measure thermal expansion coefficients, the glass transition, expansion during the melting of an embedded phase, and cure or crystallization induced shrinkage.

MATKIN: Software to Model Kinetics and Rheokinetics

MATKIN: Software to Model Kinetics and Rheokinetics

MATKIN is in house developed software is able to simulate kinetic processes such as chemical reactions and crystallization. The results can be optimized by changing the kinetic parameters in order to fit experimental measured data like for example heat flow of a differential scanning calorimeter. In addition the chemical reaction model can be linked to a molar mass model which will based on ...
