Summary: This study investigated the rheological properties of seven commercial meat sauces at different temperatures, showing pseudoplastic behavior with significant temperature effects. The sauces behaved like weak gels in oscillatory tests, with viscoelastic properties following a power law model of oscillatory frequency. The application of linear and nonlinear Cox-Merz rule proved satisfactory in correlating viscosity values at different temperatures.

Summary: This study compared the application of the Cox-Merz rule in oscillatory rheometry testing with high-pressure capillary and extrusion rheometry in determining the viscosity of HDPE pipe grades. The results indicated that for high molecular weight HDPE, viscosity data obtained from capillary pressure flow described the pressure drop in the pipe head better than data from parallel-plate rheometry applying the Cox-Merz rule, while for lower molecular weight HDPE, both measurement techniques showed good accordance.

Summary: Bigel systems were formed by combining an oleogel formed with canola oil and beeswax, and a hydrogel formed with sweet potato or chayote tuber starch. The self-standing BG exhibited uniform phase distribution and high oil-binding capacities. The droplet size and viscoelastic properties of BG were influenced by the OG : HG ratio.

Summary: Interdisciplinary study of alkali-silica reaction (ASR) provides a quantitative understanding of the viscoelastic behavior of ASR products. Six ASR gels with different compositions were synthesized, and the polymerization of SiO2 into 3-dimensional viscoelastic networks was found to depend on the concentration and type of cations. Ca2+ gels exhibited a higher level of gel network strength earlier than Na and K-dominated gels. The addition of Li+ had differing effects on the viscoelastic behavior and Q4 production of Na+ and K+ gels.

Summary: Rheology is a powerful tool for accurately assessing the fresh properties of cementitious systems. This study evaluates the effect of testing conditions on the measurement of the rheological properties of fly ash-based geopolymer paste, and finds that different testing geometries and shear rate increments have a significant impact on the results.

Summary: The rheological properties of cells have functional implications and can be analyzed using microfluidic devices and rheometers. This technique allows for the fast analysis and study of cell deformation and vitality. However, the impact of experimental conditions on the results should be considered when studying the effects of microtubule-active drugs and cells with size variation.

Summary: The identification of the percolation threshold in short fiber composites is crucial for assessing material properties and biodegradation speed. In this study, an original rheological approach was used to estimate the percolation threshold of hemp and kenaf-based composites, which showed good agreement with conventional dielectric spectroscopy analyses.

Summary: This study provides a comprehensive review of traditional and non-traditional methods for characterizing the rheological parameters of 3D concrete printing (3DCP) material. Experimental studies were conducted to compare different testing methods and identify their similarities, dissimilarities, pros, and cons. It was found that standard rheology measurement techniques have limitations when used for 3DCP material due to its unique properties, and non-conventional and novel techniques are needed for accurate rheological characterization.

Summary: This study investigates the fundamental differences in viscoelasticity between alkali-activated fly ash/slag materials (AAMs) and cement pastes, showing that the activator viscosity significantly affects the rheological behavior of AAM pastes. The temporal changes in viscoelasticity reveal negligible colloidal interactions between particles in AAM paste until initial setting, resulting in very different viscoelastic behavior compared to well-percolated network in cement paste.

Summary: Plastic pollution is a global concern, and biodegradable plastics have emerged as a potential solution. However, their lower mechanical strength and slower degradation hinder their widespread adoption. This study investigates the incorporation of New Zealand jade particles into poly(lactic acid) to enhance the performance of the resulting composite. The findings show that the addition of jade particles significantly affects the density, thermal stability, and mechanical properties of the composites, contributing to the development of sustainable solutions for plastic pollution.

Summary: This study simulated the locomotion state and motion type of elliptical squirmers in a channel flow of power-law fluids. The influence of different parameters on the squirmers was explored, and it was found that coupled structures are prone to break and viscosity significantly affects the flow velocity and motion type of squirmers.

Summary: This study investigated the electroosmotic flow of a viscoelastic fluid in a capillary system. The rheology of the fluid was characterized by a novel generalized exponential model equation, and the effect of charge density on the double-layer field and electrical forces was analyzed. Mathematical models were used to describe the rheological properties and flow performance of the fluid, and experimental data were used to make predictions. The study also examined the influence of applied forces on the structure of the fluid.

Summary: This article presents a multi-step, iterative technique for locally non-parametric identification of the standard linear solid (SLS) material model using fractional order time differential operators. Test input data consists of a set of identified material complex modulus values estimated at different frequency values obtained from input-output experimental measurements and quasi-static relaxation measurements on the same specimen. The proposed technique is based on an algebraic procedure to solve an overdetermined system of linear equations in order to obtain optimal values for the unknown parameters of the model. The procedure is non-parametric, as the order of the SLS model is initially unknown.
