PEG-PCT) has been successfully synthesized via ring opening polymerization. By adjusting initial monomer feeding ratio, TOSUO molar content in the hydrophobic block increases from 0% to 20% while the repeat units of the blocks remain [...]

Additive “4D” Rheoprinting for the Manufacture of Enhanced Biomaterial Products

Duhduh A., Jaafar I.H., Coulter J.P., Lehigh University, US

A novel additive manufacturing technique, which we have coined as the “4D Rheoprinter”, has been developed. This technique enables 3D printing of polymers with tunable material properties for optimized performance in wide range of applications. [...]

Capillary flow of whole blood in microsystems: non-Newtonian blood behavior and substrate reagent-coating effect

Berthier J., Gosselin D., Huet M., Sabatte G., Cosnier M.L., Pouteau P., Cubizolles M., CEA-Leti (University Grenoble Alpes), FR

Introduction: The use of whole blood is a preferred solution for portable diagnostic and monitoring systems. We analyze here two particularities of microsystems for blood analysis: the blood non-Newtonian behavior, and the capillary flow in [...]

Rheological Characterization of a Novel Viscoelastic Surfactant for Subsurface Applications

Liebum M., Nguyen Q.P., The University of Texas at Austin, US

Viscoelastic solutions (VES) are used in many applications including oil and gas operations regarding reservoir stimulation and enhanced oil recovery to modify rheology properties in the subsurface. In general, the viscoelastic property of the surfactant [...]

SRD-MD modelling of hydrodynamic interactions in colloidal systems: playing between computational cost and resolution

Laganapan A.M.K., Videcoq A., Cerbelaud M., Mouas M., Bienia M., Ferrando R., Science of Ceramic Processing and Surface Treatments (SPCTS), FR

A ubiquitous problem that has always been a subject of intensive research is the role played by hydrodynamic interactions (HI’s) in several fundamental problems in colloid rheology and aggregation kinetics. However, the high computational demand [...]

Polymer Gels: Fracture, Friction, Healing and Superabsorbency

Erk K.A., Purdue University, US

Polymer gels have many industrial uses, from drug-delivery and wound-healing materials to the superabsorbent gels used in baby diapers as well as high-performance concrete. The macro-scale physical properties of the polymer gels, including the gel’s [...]

Development of alternative binder for lithium ion battery based on epoxy resin

Bunzel F., Wagner M., Stammen E., Dilger K., Technische Universität Braunschweig, DE

The development of batteries for the e-mobility continuously creates new challenges for the researchers. To improve performance of lithium ion batteries, different approaches might be considered. Therefore the Institute of Joining and Welding (ifs) focuses [...]

Rheology of Portland cement pastes with calcined clays additions

Irassar-Viviana Rahhal E., Pedrajas C., Talero R., Universidad Nacional del Centro de la Provincia de Bs.As., AR

In this paper, the rheological behavior of pastes of Portland cement and different calcined clays additions were analyzed. For this purpose, two Portland cements with different mineralogical composition (low C3A and high C3S content and [...]
