WebApr 13, 2024 · This work reports that the rheology of ideally monodisperse lambda (λ $$ \lambda $$) phage DNA solutions is extremely sensitive to the applied strain in dynamic oscillatory experiments.λ $$ \lambda $$ DNA exhibits nonlinearity at strains far smaller than what is observed in conventional synthetic polymers. However, it is found that … In practice, rheology is principally concerned with extending continuum mechanics to characterize the flow of materials that exhibit a combination of elastic, viscous and plastic behavior by properly combining elasticity and (Newtonian) fluid mechanics. It is also concerned with predicting mechanical behavior (on the continuum mechanical scale) based on the micro- or nanostructure of the material, e.g. the molecular size and architecture of polymers in solution or the particle size …

WebOct 11, 2024 · Dynamic oscillatory shear testing is used to investigate polymeric viscoelastic behaviors. Small and large amplitude oscillatory shear tests are the canonical method for characterizing the linear and nonlinear viscoelastic behaviors of any polymeric material. With prominent and abundant work on linear viscoelastic studies, the nonlinear …
WebDynamic tests to monitor changes in structure are usually conducted at a single frequency. In order to perform a more detailed characterization, the rheological properties of a sample may need to be measured at multiple test frequencies. This is typically done in a frequency sweep test, where data is collected point-by-point at each frequency.
