Thermogravimetric Analysis of Powdered Graphite for Lithium-ion Batteries
In this note, TGA will be performed on natural and synthetic graphite of various particle sizes. The analysis will provide information that would find value in quality control settings, such as batch consistency and impurities.
Auto-Trim Accessory
The auto-trim accessory for the DHR simplifies polymer melt rheology by automating the sample heating and trimming process.
Polymer Melt Rheology Workflow Automation: Auto-Trim Accessory for Discovery Hybrid Rheometers
The 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.
Rheology as a Suitable Tool for Quality Control of Collagen Hydrogels
Here, a standard operating procedure (SOP) for determining the quality of collagen hydrogel was developed using oscillatory rheology with a DHR-2 rheometer.
Preventing Wall Slip in Rheology Experiments
Wall 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.
Monitoring DNA Melting using Nano DSC
In this application note, we used the Nano DSC to monitor ST-DNA melting at a range of concentrations in phosphate buffer.
