Capillary rheometers are especially advantageous for characterization of therapeutic protein solutions since it determines the ability to be syringed. [6] Additionally, there is an inverse relationship between the rheometry and solution stability, as well as thermodynamic interactions. Rotational geometries of different types of shearing rheometers
Capillary breakup rheometry is an experimental technique used to assess the extensional rheological response of low viscous fluids. Unlike most shear and extensional rheometers, this technique does not involve active stretch or measurement of stress or strain but exploits only surface tension to create a uniaxial extensional flow.
Measuring principle: The slit viscometer/rheometer is based on the fundamental principle that a viscous liquid resists flow, exhibiting a decreasing pressure along the length of the slit. The pressure decrease or drop ( ∆ P ) is correlated with the shear stress at the wall boundary.
Rheology (/ r iː ˈ ɒ l ə dʒ i /; from Greek ῥέω (rhéō) 'flow' and -λoγία (-logia) 'study of') is the study of the flow of matter, primarily in a fluid (liquid or gas) state but also as "soft solids" or solids under conditions in which they respond with plastic flow rather than deforming elastically in response to an applied force.
Much like the Meissner-type rheometer, the SER rheometer uses a set of two rollers to strain a sample at a given rate. [31] It then calculates the sample viscosity using the well known equation: σ = η ϵ ˙ {\displaystyle \sigma =\eta {\dot {\epsilon }}} where σ {\displaystyle \sigma } is the stress, η {\displaystyle \eta } is the viscosity ...
U.S. News & World Report just rated the Mediterranean diet as the No. 1 diet for the eighth year in a row. Not only did it win best overall diet, it also won the top spot for managing diabetes ...
For example, a typical ER fluid can go from the consistency of a liquid to that of a gel, and back, with response times on the order of milliseconds. [1] The effect is sometimes called the Winslow effect after its discoverer, the American inventor Willis Winslow, who obtained a US patent on the effect in 1947 [ 2 ] and wrote an article ...
