A microfluidic approach to studying the injection flow of concentrated albumin solutions

open access: yesSN Applied Sciences, 2021
Subcutaneous injection by means of prefilled syringes allows patients to self-administrate high-concentration (100 g/L or more) protein-based drugs. Although the shear flow of concentrated globulins or monoclonal antibodies has been intensively studied ...

Constitutive modeling for the flow stress behaviors of alloys based on variable order fractional derivatives

open access: yesMaterials Research Express, 2022
During hot working, alloys may experience three kinds of flow stress behaviors, including strain hardening, strain softening, or steady flow, because of the competition of work hardening and thermal softening. Modelling the flow stress behaviors plays an

Energy Dissipation in the Human Red Cell Membrane

open access: yesBiomolecules, 2023
The membrane of the human red cell consists of a lipid bilayer and a so-called membrane skeleton attached on the cytoplasmic side of the bilayer. Upon the deformation of red cells, energy is dissipated in their cytoplasm and their membrane.

Development of Dressing-Type Emulsion with Hydrocolloids from Butternut Squash Seed: Effect of Additives on Emulsion Stability

open access: yesGels, 2022
Background: Natural ingredients have been employed to develop food products. Methods: Hydrocolloids from butternut squash seeds (HBSSs) were extracted with water at pH 3, 7, and 10 and characterized bromatologically and rheologically; then these HBSSs ...

The Rheology of Binary Mixtures of Highly Concentrated Emulsions

open access: yesApplied Rheology, 2011
The rheological parameters (elastic modules and the yield stress) of binary mixtures of highly concentrated emulsions with different droplet sizes can be several times lower than additive values in a certain range of concentration. This is related to the

A Microfluidic Prototype for High-Frequency, Large Strain Oscillatory Flow Rheometry

open access: yesMicromachines, 2022
We introduce a “Rheo-chip” prototypical rheometer which is able to characterise model fluids under oscillatory flow at frequencies f up to 80 Hz and nominal strain up to 350, with sample consumption of less than 1 mL, and with minimum inertial effects ...

Developing Biodegradable Films from Mango (Mangifera indica) Starch and Extract: A Rheological and Physical Study

open access: yesGels
The development of biodegradable films with antioxidant properties offers a promising approach to food preservation. This study focused on creating and characterising mango starch-based films enriched with mango peel extract (MPE) at concentrations of 0,

Oleogels Based on Starch and Natural Extracts from Cassava (Manihot esculenta) as a Fat Replacement in Cookies

open access: yesApplied Sciences
Oleogels, a semi-solid fat-like material, have emerged as a promising alternative to traditional saturated fats in food products. This study aimed to develop and characterize novel oleogels using starch and extracts from cassava (Manihot esculenta) to be

Rheology and zeta potential of cement pastes containing calcined silt and ground granulated blast-furnace slag

open access: yesMateriales de Construccion, 2011
This study aimed to analyse the re-use of dam silt as a supplementary binder for self-compacting concrete (SCC). When burnt, silt becomes more reactive because the kaolin it contains is converted into metakaolin.

Application of Fractional Calculus to Modeling the Non-Linear Behaviors of Ferroelectric Polymer Composites: Viscoelasticity and Dielectricity

open access: yesMembranes, 2021
Ferroelectric polymer composites normally show non-linear mechanical and electrical behaviors due to the viscoelastic and dielectric relaxation of polymer matrixes. In this paper, a fractional calculus approach is used to describe the non-linear behavior
