Research news on Rheology techniques

Rheology techniques comprise experimental methods used to characterize the flow and deformation behavior of materials under applied stresses or strains, typically by quantifying relationships between shear stress, shear rate, and time. Core approaches include rotational rheometry (e.g., cone-plate, parallel-plate, and concentric cylinder geometries) for steady and oscillatory shear, capillary and microfluidic rheometry for high shear rates, and extensional rheometry for elongational flows. These techniques enable determination of viscoelastic moduli, yield stress, viscosity functions, thixotropy, and nonlinear responses, supporting constitutive modeling and microstructure–rheology correlations in complex fluids, soft solids, polymers, gels, and suspensions.

Reduce rust by dumping your wok twice, and other kitchen tips

When you reach the bottom of a container of milk or honey, you might be tempted to tip the container over to get that last pesky little bit out. After all, you only need another teaspoon for that recipe, and you're sure it's ...
