DOI: 10.1016/j.icheatmasstransfer.2019.05.008

Abstract: Abstract Cavitation in a transparent centrifugal pump has been experimentally investigated using viscoelastic fluid. Viscoelastic fluids are aqueous solutions of polyacrylamide with different concentrations of 100, 200, and 400 ppm at room temperature. The cavitation inception… read more here.

DOI: 10.1016/j.jmbbm.2020.104131

Abstract: Currently, Periodontal ligament (PDL) is considered as a viscoelastic solid biomaterial. However, we observed the steady-state rheological behavior of PDL through long time loading experiments, and suggested the theoretical definition of PDL as a viscoelastic… read more here.

DOI: 10.1016/j.jnnfm.2019.104222

Abstract: Abstract Microfluidic contraction devices have been proposed for extensional rheometry measurements, in particular as a useful method for determining the extensional viscosity of low elasticity solutions. The first commercially available “Extensional Viscometer-Rheometer-On-a-Chip” (e-VROCTM), developed by… read more here.
