DetailsThis application note discusses how to use rheology to evaluate the influence of graphite particle size and particle shape on the rheological behavior of a battery slurry.
DetailsIn this application note, a TA Discovery HR rotational rheometer facilitates coating optimization by measuring slurry viscosity over different shear rates that relate to coating speed. Drying kinetics are investigated with a Discovery TGA to yield the most cost-efficient condition.
DetailsA rheometer is a powerful instrument that can be used to monitor the gel formation and also to measure the gel strength. Two case studies are discussed regarding the use of a TA Instruments’ rotational rheometer to analyze the properties of different types of hydrogels.
DetailsWall slip is a common problem when testing highly concentrated emulsions or suspensions on a rheometer. It is usually caused by large velocity gradients in a thin region adjacent to the wall. When slip occurs, the measured viscosity can be significantly lower than the actual viscosity of the sample. To overcome this influence, we have introduced a series of roughened surface geometries, such as crosshatched or serrated plates, which significantly improve the contact between the geometry and the sample to reduce slip.
DetailsTA Instruments’ High-Pressure TGA (HP-TGA) enables users to investigate stability and lifetime of polymers under realistic working conditions, assessing not only the effect of temperature on material stability, but also the effects of high pressure and possibly corrosive atmospheres.
DetailsIn this note, the processing behavior of two lactose excipients is studied by measuring shear and flowability of milled and spray-dried lactose. Milled lactose was found to have higher cohesion, yield strength, confined and unconfined flow energies when compared to spray-dried lactose.
DetailsThe TA Instruments Powder Rheology Accessory was used with Discovery HR 30 rheometer to perform shear measurements. Duplicate measurements were performed with fresh samples under ambient conditions.
DetailsThe auto-trim accessory for Discovery Hybrid Rheometers automates the melting, gap setting, and crucial sample trimming step in polymer melt rheology testing. The automation of this step improves data consistency by up to 5x, increases continuous walkaway time by 80%, and reduces new operator training time to less than 30 minutes.
