As can be observed from the figures, all of the hydrogels exhibited a storage modulus ( G ’) that was always higher than the loss modulus ( G ”), denoting that the … A rheometer is a laboratory device used to measure the way in which a viscous fluid (a liquid, suspension or slurry) flows in response to applied forces. It is used for those fluids which cannot be defined by a single value of viscosity and therefore require more parameters to be set and measured than is the case for a viscometer. It measures the rheology of the fluid. notorious news https://aplustron.com
