Modifying food texture is a valuable approach to enhancing the quality of life for patients with dysphagia. Incorporating thickened soy protein-based liquid systems (SPLS) into their diet not only improves protein intake but also promotes safer swallowing. However, the properties of thickened SPLS are crucial for safe swallowing, may vary depending on the conformation of the thickened polysaccharides used. In this study, SPLS with different levels of thickening were prepared using xanthan gum, pectin and guar gum. The influence of polysaccharide conformation on the rheological (shear and extensional) and tribological properties of thickened SPLS was investigated. The results revealed that xanthan gum-thickened SPLS exhibiting the highest shear viscosity (110.073 Pa.s) and extensional viscosity (7.405 Pa.s), which increased with polysaccharide concentration. Meanwhile, xanthan gum possessed the strongest lubricating properties. These results shed light on the development of plant protein-based solutions for dysphagia management.

The nanocellulosic pellicle derived from the symbiotic culture of bacteria and yeast (Kombucha SCOBY) is an important biomaterial for 3D bioprinting in tissue engineering. However, this nanocellulosic hydrogel has a highly entangled gel network. This needs to be partially modified to improve its processability and extrusion ability for its applications in the 3D bioprinting area.

The generation of long-chain branches (LCB) in biobased and biodegradable polylactide (PLA) by adding different amounts of a chain extender is studied. The rheological and calorimetric behavior have been used to determine the effect of LCB presence and their topology on PLA melt strength and crystallization behavior. Rheological modeling of linear and non-linear viscoelastic shear and extensional properties identified several possible branched structures.

Drops in extensional flow undergo a deformation, which is primarily fixed by a balance between their surface tension and the viscous stress. This deformation, predicted and measured by Taylor on millimetric drops, is expected to be affected by the presence of surfactants but has never been measured systematically. We provide a controlled experiment allowing us to measure this deformation as a function of the drop size and of the shear stress for different surfactants at varying concentrations.

In the realm of tissue engineering, replicating the intricate alignment of cells and the extracellular matrix (ECM) found in native tissue has long been a challenge. Most recent studies have relied on complex multi-step processes to approximate native tissue alignment. To address this challenge, we introduce a novel, single-step method for constructing highly aligned fibrous structures within multi-modular three-dimensional conglomerates.

Enhanced oil recovery (EOR) methods are generally employed in depleted reservoirs to increase the recovery factor beyond that of water flooding. Polymer flooding is one of the major EOR methods. EOR polymer solutions (especially the synthetic ones characterized by flexible chains) that flow through porous media are not only subjected to shearing forces but also extensional deformation, and therefore, they exhibit not only Newtonian and shear thinning behavior but also shear thickening behavior at a certain porous media shear rate/velocity.
