Rheology of Rapid Kinetics
Summary Quantifying changes in rheological properties of fluids undergoing rapid physical change is a non-trivial feat. Certain stimuli (like UV-light, electrical fields, magnetic fields, chemical species interaction, or heat) can initiate rapid changes in rheological properties (viscosity, modulus, etc.). Example systems could include hemostatic agents intended to rapidly coagulate blood, or curing hydrogels for use […]
Yield Strength Rheometry
This application note examines yield stress, highlighting its importance in determining when materials begin to deform or flow. Yield stress is crucial for products like hair gels and adhesives, which must maintain shape until a specific force is applied. It outlines two methods for measuring yield stress: applying an increasing force and using a steady […]
