Summary: This paper studies the rheological properties of organic kerosene gel and fits constitutive models to describe the relationship between viscosity and shear rate, temperature, and shear history. It is found that intense pre-shear can reduce viscosity, and the viscosity-temperature relationship can be approximated by an empirical power law. The fitted second-order kinetic model accurately corresponds to the viscosity at different shear rates and shear times.

Summary: The study investigates the degradation behavior of a triblock-copolymer surfactant made from polyethylene oxide (PEO) and polypropylene oxide (PPO) (PEO-PPO-PEO), showing how the aggregation behavior of this polymer in water changes with aging. It was found that degradation of the polymer surfactant leads to significant mass losses and alters aggregation behavior, forming larger rod-like or planar aggregates over time. Interaction between the polymer surfactant and poly(N-isopropylacrylamide) microgels was studied, highlighting the potential dramatic changes in aggregation behavior and formulation properties of commonly used polymeric surfactants over time.

Summary: Recent progress in elastohydrodynamic lubrication (EHL) has been achieved through a shift in method from adjusting viscosity as a parameter to measuring it using viscometers. However, measuring shear-dependent viscosity in lubricating oils is challenging due to other phenomena affecting constitutive behavior. The lack of understanding of thermal feedback in viscometers has resulted in wasted effort in EHL friction research.

Summary: By analyzing the experimentally measured bond networks of colloidal particle gels, the contradiction between variations in shear moduli and colloidal volume fraction changes is resolved. It is found that structural heterogeneity of the gels is crucial in understanding frequency-dependent elasticity. A phenomenological spring-dashpot model that accounts for the interplay between fluid viscosity, particle dissipation, and contributions from the affine and non-affine network deformation leads to a universal collapse of shear moduli.

Summary: A recent experimental study demonstrates that locally ordering colloidal gels can be achieved by acoustically modulating an embedded microbubble. In this study, Brownian dynamics simulations were performed to investigate the mechanical effect of an oscillating microbubble on the gel structure. The simulations reveal the presence of hexagonal-close-packed structures within the range of oscillation amplitudes. However, the unexpectedly long-ranged modification observed in the experiment could not be reproduced in the simulations, suggesting the need to consider long-ranged effects such as fluid flow in future computational work.

Summary: This work develops a thermodynamically consistent microscopic model for a suspension of aggregating particles under arbitrary, inertia-less deformation. The model takes into account the lognormal distribution of the aggregate size population, the aggregation and breakup processes, and the viscoelastic description of the elastic network of the particle aggregates. The model predictions are consistent with the observed rheological behavior of typical systems of aggregating particles. Additionally, an expression for the total entropy production is provided to evaluate the importance of dissipative phenomena in flow processes.

Summary: Researchers have developed Rheology-Informed Neural Networks (RhINNs) to accurately predict the fully resolved solution of constitutive equations for complex fluids under various flow protocols. RhINNs can learn non-trivial model parameters for complex materials using a single flow protocol, enabling accurate modeling with limited experiments. RhINNs are not limited to a specific model and can be extended to recover complex manifestations of kinematic heterogeneities and transient shear banding of thixotropic fluids.

Summary: The study investigated the cleaning efficiency of aqueous solutions of four different surfactants on removing post soldering flux residue from printed circuit boards. It found that different surfactants showed varying ability to disperse the residue, and the selection of an effective cleaner should consider solubilizing or dispersing the residue, low surface tension and contact angle on the substrate, as well as matching polar and dispersive components of the solution's surface tension with the substrate's surface free energy.

Summary: This study synthesized biochar based on sapropel and investigated the effects of chemical modification on its textural characteristics, acid-base properties, and adsorption properties. The results showed that the chemical modification increased the fraction of micropores, specific surface area, and changed the surface properties of biochar. The experiment also revealed that biochar pretreated with alkali exhibited the maximum adsorption capacity for copper ions. A conceptual model identifying the mechanisms of copper adsorption on sapropel-based biosorbent was proposed.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
