This study had a threefold purpose: 1) study the creep response of bone to repetitive phsyiologically-relevant loading 2) to perform these types of tests on a small scale; and, 3) to illustrate and identify age-related effects on the mechanical properties of bone.
DetailsModulated DSC (MDSC) was performed on a polypropylene (PP) battery separator to gain additional insights into the effects of stretching during processing of the film.
DetailsModulated thermomechanical analysis (MTMA) was performed on a polypropylene (PP) battery separator to gain further insight into the mechanism of the dimension change and coefficient of linear expansion (CLE or α).
DetailsIn this application note, we used the Nano DSC to monitor ST-DNA melting at a range of concentrations in phosphate buffer.
DetailsChoosing to model DSC data can give additional insight into the unfolding process of a macromolecule or be helpful to deconvolute a multiple transition thermogram. This application note will discuss general guidelines of choosing the correct baseline and DSC model.
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.
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.
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.
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.
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.
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.
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.
