Recently, research on particle migration in non-Newtonian viscoelastic fluids has gained
considerable attention. In a viscoelastic fluid, three dimensional (3D) particle focusing can …

Single polymer dynamics offers a powerful approach to study molecular-level interactions
and dynamic microstructure in materials. Direct visualization of single polymer chains has …

Delayed capillary break-up of viscoelastic filaments presents scientific and technical
challenges relevant for drop formation, dispensing, and adhesion in industrial and biological …

We investigate theoretically the steady incompressible viscoelastic flow in a hyperbolic
contracting channel. The fluid viscoelasticity is modeled using the upper convected Maxwell …

We analyse the pressure-driven flow of the Oldroyd-B fluid in slowly varying arbitrarily
shaped, narrow channels and present a theoretical framework for calculating the …

We elucidate the influence of chemical structure on macromolecular hydrodynamics,
rheological response, and pinching dynamics underlying drop formation/liquid transfer using …

We show that poly (ethylene oxide)(PEO) solutions formulated using solvent mixtures of
acetonitrile (AcN) and water can be centrifugally spun into fibers. We find that spinnability …

Quantitative studies of capillarity-driven pinching and extensional rheology of aqueous
solutions of polysaccharides like hydroxyethyl cellulose (HEC) are beyond the measurable …

Charge-bearing groups that ionize in solution influence the macromolecular conformations,
interactions, and dynamics of polyelectrolytes. The rich and complex shear rheological …

Understanding and characterizing the influence of polymers and surfactants on rheology,
application, and processing is critical for designing complex fluid formulations for enhanced …
